Pros: 1. Relatively good value in an e-bike as of Jan/2018 @ $1400 2. 625Wh Battery. Very good battery capacity, well suited to the bike over all. 3. Quick-Release removable battery, easy to swap. 4. Decent general consumer mid-range components 5. Includes lots of small accessories with the bike (Kickstand, head-light, reflectors, fenders, bell) 6. Includes manual throttle control as well as automated Assist mode for electric motor 7. Easy assembly, mostly assembled in the box 8. Vendor is accessible Cons: 1. Seat was uncomfortable 2. Documentation is inadequate, and does not cover much beyond assembly. Provided instructions are out-of-date and incomplete. 3. Factory failed to tighten steering stem cap, a slight QC issue. 4. Gear/chain adjustment from the factory needed tuning. Components may need break-in time, so slight adjustments will be needed over time. No instructions on performing these adjustments. 5. A red rear-reflector or tail-light is not provided. 6. Mud guards are insufficient. 7. Very small company, buys bikes from OEM in China. This is mitigated by the use of good standard components, so the bike serviceable by any knowledgeable person or service center. Rating: 5 stars, in the current environment this bike is a great value with generally good quality components, including the very important battery. All the small included accessories means you can be up and riding quickly without too much time spent finding and buying additional accessories. General Recommendations: 1. Switch the seat to something comfortable if it does not work for you. Very important to have a nice seat. 2. Switch the pedals to these Race Face Chester Pedal Black, One Size . 3. Get a red rear reflector, or better a red tail-light. Even for day time use. 4. If your bike came assembled with the Bell next to the left hand grip, I suggest you remove it from there and move the controller switch right next to the handgrip for much easier and more ergonomic access to the important speed control. You can actually mount the bell on the support arm for the brake-level and have excellent access to that as well. (see attached picture). 4. Taking it into a bike shop for small adjustments might help get the fit right for you if you don't have the time or the ability to do the tweaks yourself. The Long Story: THE FIRST 24 HOURS - 2018.01. 27 This is not the perfect e-bike (or e-bike package), but I believe it is a 5 star package. I had been thinking about an e-bike for a while, but price, quality and the battery capacity (very important to me) never really came together at a price I was happy with. This bike met my main requirements starting with the battery capacity and quality (based on cell manufacturer used and certifications). The more traditional design and component specs appealed to me as well. So I bought this on a whim really when it popped up as a suggestion. Read a couple reviews on-line at Amazon and other places and decided it was worth a try. Two days latter it was delivered (a signature was required which was unfortunate, they should have let the driver decide). My seasoned UPS driver of almost 2 decades and I, decided it was very well packaged. The plastic handle inserts for the box were all missing except 1, and one wrap had come off somewhere along the line (probably dragging it in or out of the truck), and there was a very small amount of box damage near the rear wheel where the kickstand folds up. Over all very happy, very heavy corrugated box. So far so good, everything arrived undamaged and complete, no missing pieces, unlike a scooter I got recently which I've still not been able to get right. The bike frame did have a couple of scratches on it exposing the metal under the paint, but these were done before the protective wrap was put on the bike. I colored them and put gaffer's tape bandaids on them for now. The frame is aluminum so no worries on rusting, I got rid of the juvenile Top Gun stickers from the forks, but I wasn't able to do anything yet about the large DJ Bikes logos on the crossbar which I'l like to remove. I'm sure most would just leave all the stickers alone and be happy with them. Battery Charging. Pretty straight forward, I always do this first (and they recommend to as well). I wanted to charge it with the battery off the bike. There were no instructions on how to remove the battery so it too me a while to figure out the lock was controlled by the on/off key because I was looking at the bike from the other side. Charging was actually really quick, just about an hour and I was expecting a lot longer. This meant the battery must have been quite fresh, but also strange as usually they are shipped at storage charge levels, this one was clearly not. The instructions were wrong about the charger, a typo said the light should be green while charging, when it should be red, but the picture showed it correctly to be red. It was also obviously a mistake because the next paragraph indicated the battery was fully charged when the light was green. While charging there was no indication of how much the battery was charged which is a little annoying and too basic for me. It's always great though when the battery charges without issue. Assembly; This was pretty easy, it comes mostly assembled, only having to attach the front wheel and fender, handle bar, seat, pedals and head lamp. The instructions are not the clearest, and they are not even correct in some cases as I guess the components have changes a bit (e.g. no front bracket for wires). There were no instructions on mounting the Headlamp which mounts with the fender screw. The bike comes with a pretty large Bike-Tool for assembly and maintenance that contains Allen-keys, wrenches, Phillips screwdriver, some sockets, etc. It's very nice that they included this tool rather than just a couple Allen keys or nothing at all. I assembled using my own quality tools, needing just 6mm, and 5mm hex/Allen keys, a 15mm wrench for the pedals, and a Phillips to adjust the headlamp I think it was. The included 15mm wrench will scar the pedal bolt a bit as it is thin and non-precision. After Assembly I rode it without the battery to give it a bit of a shakedown to see if it all held together, get a feeling for the gears and breaks, and then a bit more to get the seat height correct. The components such as the gears and breaks all seem to come adjusted adequately out of the box. I'm very impressed with the overall package. It included almost all essentials missing only a rear reflector or light. I didn't have to spend extra for a kickstand, or fenders. I didn't have to remove the small bell from my traditional bike or get a new one of these, it included basic wheel reflectors in the spokes, and even a bottle carrier and a small aluminum water bottle. These extras are often skipped and one has to get them later. Even if one wants to update the accessories, it's nice to have a complete package. This really impressed me. I would have loved a rear carrier, but I actually agree with them leaving this out out of the package for price and widely differing preferences. I would recommend one get a rear reflector at minimum and better a light, even if only daylight riding it is more important than the headlamp during the day. The headlamp won't even begin to meet my requirements, but I was impressed it was provided in the package, and it include a white reflector as well which is always useful (a basic requirement). You'll probably have to go to their website to figure out how to turn it on (hold Mode and Up together for 2-3 seconds). I will reserve this light for emergencies only. I mounted a good bike head light on the frame and electrically disconnected the supplied one. I had to disconnect the supplied one because the control to turn on the head-light also turns on the LCD backlight on the control-center which I need for riding when it is darker and I did not want the head light shining or wasting my battery. I mounted a small Hotshot USB rechargeable Tail Light to the seat post for rear visibility. One must remove the seat (quick release) in order to remove or insert the battery. Operation. My package had NO information about operation of the e-bike after assembly. Having never ridden an e-bike I was a bit taken back on how the assist worked from a stop if one is not careful. I can now understand what others have told me about their first bike experiences. The Assist defaults to ON (Level 1) when the bike it first powered ON; I would prefer it to default to OFF. After turning on the Key, one must hold the Mode Button on the controller to turn on the bike (this was not in my manual, but easy enough to figure out). I figured out most of the controls without the manual, and set the time and such on the control center. I later found a manual on-line for the the King Meter J-LCD model, but it was not too useful since I had already figured out the operations. It did contain one useful thing I had not found and that was a Walking Mode, that offers a 6 km/h assign intended to help when walking the bike. This could be very useful for walking uphills with the bike. It warns against not trying to ride the bike in this mode. I did not test this mode yet as I was already done for the day when I was reading the manual. First rides. I rode the bike for 17km the first day in mainly 2 short trips. The bike performed great, and this is what I had hoped for. Compared to my Segway Mini Pro, this e-bike has the speed to get more more places quicker and without having to swap out the battery, an unpleasant option on a Segway in Winter. The bike moves without effort on level ground, but was also able to make it up a steep hill on battery alone, although it was not too happy about it. With just a little pedaling it was much happier on hills. I was surprised that I could get a bit of a workout in assist mode, and since I'm not in the best of shape this is a good thing I think. The bike seems to be happy at 20km/h in Assist Mode 1, and does not really like going slower than that, one has to use the break and the pedals accordingly when going slower is needed. It would be really nice to have a nice left thumb accessible button to quickly turn Assist OFF or ON to the Last level. Having to press the button on the control center is a bit distracting, The good news is I was able to do it with gloves on. I have not looked into if the control center can be replaced with a different model in the future, but I suspect it can if needed. I didn't find the seat very comfortable, but was happy with all the other components. As with all e-bikes the controls on the right hand are not optimally placed because of the extra width needed for the throttle control places the front-brake level and gear-shift a little further away than they should be. Still this didn't cause any huge problems and it's pretty common with many bikes. The throttle could be removed, as it is not really required for everyone, but I like having it. I didn't get to use the gears much, but the gearing is pretty 'pedestrian' I'd say. No problems starting it on level ground in top gear (7), but moving against the wind in Assist Mode 1, I could get a bit of a workout in the top gear. Still for me gears 6 and 7 seem like they will be used the most to almost exclusively; switching between these two gears worked well. On a couple hills I tried the other gears as low as 3, but not long enough to get a feeling for them or how well the shifter was aligned and operating/locking in those gears. My preference would be to have a couple higher gears. Initial Impression (* * * * *). This bike is a great value and is of very good quality. Including almost all the small essentials in the package to get going is a really nice touch. The documentation, or links to e-bike operation, needs to be updated, and the assembly manual could use a few tweaks. A youtube assembly video is probably the way to go for most people, that would make it a snap for anyone This bike is worth trying if you are looking for a 26" sized e-bike that has decent construction and a decent battery at a very fair price ($1400 at this time). AFTER THE HONEYMOON During next shake down cruise I did run into a couple of issues. Luckily I had thrown in the Bike-Tool provided with the bike into my pocket just in-case. After a short off trail ride there was a definite rattle. Took a few minutes to track it down to the Handlebar Stem cap. It had become very loose, I could lift it more than an inch, but when the bike was stoped it was sitting down properly and so did not look loose. This adjustment is not touched during assembly so I can only assume that it was incorrectly tightened during assembly. I should have inspected all the bolds during assembly but I had forgot to check that one. Luckily on this type of handle bar assembly I believe it is completely non-structural, bit don't hold me to that. I tightened it with a hex key and was ready to continue. It did remind me also that I had not adjusted the height of the handle bars. Turns out that is not mentioned at all in the manual, and I would like to do it. The seller says "it 'should' be possible" so something for me to look into very soon. Problem number 2, started shortly there after with the chain slipping from time to time, not slipping out of gear per-say, just slipping. I stopped and a couple pushes on the derailed and it seemed good, but only for a very short time. I stoped and tried to investigate, and determined that the tension on the chain was way too loose. I used the Phillips on my Swiss Army knife to give the tension adjustment two roughly 1/4 turns, maybe a bit more, and it seemed rock solid. I made it back about 10km without any further issue. Many people would not know how to make this adjustment so I think the instructions need to be updated a bit. I'll go back and look at the guild for the basic components and see how much they mention that. Since the gearwheel and drive was assembled prior to delivery I feel this was a manufactures issue with the assembly. The controller for the bike is pretty basic; it's battery level is very primitive and wavers like a willow in the wind. Keep track of your trip mileage and don't rely on the controller gauge for an accurate indication of the battery level. I don't yet know if the gauge on the battery is any better since you have to stop and get off the bike to activate that and it looks to be too low of resolution to tell you anything other than if the battery is fully charged. At this point I had 40km on the bike, and put the battery on the charger. It took roughly 4hrs to finish charging. Adding a rear cargo carrier; I mounted a rear carrier on the bike. The ' Topeak Super Tourist Tubular Bicycle Trunk Rack DX with Side Bar for Disc Brake Bikes ', see my review here: https://smile.amazon.com/gp/customer-reviews/RS6TY8FSHPPZG/ref=cm_cr_dp_d_rvw_ttl? ie=UTF8&ASIN=B000ZKHN6Y Waiting for the weather to warm up to put some more miles on the bike. If you are thinking about buying your first e-bike you better check the laws for your region. Here in Massachusetts, the laws read like there were written in the 1900s. If you ride the transit system in Boston you will understand how far behind in transportation thinking the state is. 2018.02.14 Update At this time I have 63km on the bike, and the gears are still giving me a little trouble, but I've not made any additional adjustment just yet. I'm thinking the springs and everything in the derailed need to be broken in a bit. The mud guards are insufficient, even in very mild wed conditions the mud spray is too great. There is a very large gap between the centermost and where the rear fender starts, this means you and the battery can get lots of spay even when there is little water on the road or trail. I'll be patching this up a bit with plastic and zip-ties I suspect soon. The ride is nice, although I did switch out the seat, the other one seemed to create hotspots and was uncomfortable even though I had adjusted to it somewhat. Replaced it with this well rated saddle Sunlite Cloud-9 Bicycle Suspension Cruiser Saddle, Cruiser Gel, Tri-color Black , but that took a little work. It's really a bit too wide for this bike, but it seems comfortable and should work until I can find something more suitable. See my review on it for more details. 2018.02.23 Update Put a few more miles on the bike, and still tweaking it. Fixed up the rear fender using a second 1/2 fender to extend the guard all the way to the base of the bike; a nice improvement for wet roads and trails. There is only a small gap now where the two guards join at the mounting clamp. I will be patching that up shortly. I decided that the console control was too important and the bell got in the way of easy access with my hand on the left grip. I was going to swap the positions of the bell and the controller sacrificing access to the bell. I noticed on the company's website that they had pictures with the components in this order so I thought yup makes sense... then I did something better... after moving the controller input next to the hand-grip I found I could mount the bell on the support arm for the brake-lever. So perfect! Now I have quick and convenient access to the bell and the controller (see attached picture). Then it was time to raise the handlebar.... I decided to first try the built-in adjustment at the neck... the problem with this is it also tilts the handle bar and moves it slightly back.... more after testing. I'm still interested in knowing if the existing stem can be raised. 2018.02.25 Update Over 100km on the bike now. The gears/derailer seem to have settled in and have been great for the last 40km or so. The new position for the electrics control switch, and the bell are working fantastic, If your bike came with the bell in-between the handgrip and the control switch, I highly recommend moving them. I was a a bit silly when I adjusted the height of my handle bar and then twisted all the components on the bar so they were level again. The handle-bar is not actual straight, so raising it with the head adjustment actually tilts it incorrectly to. The way to adjust it properly is to simply loosen the head afterwards and rotate the entire bar like you did during installation. This puts all the controls back and the bar in the right orientation. I've raised mine quite a bit for a more upright riding position and to better suit the length of my arms. I've tilted my brake levers a bit lower than they came, and moved the 'high-beam' switch from my 3rd-party add-on headlight to the right-hand brake-lever support like the bell on the left side, and it is perfect for that. I'll likely be switching the saddle again, the C9 is just not the right one for me using this as a road and trail bike. The C9 is pretty comfortable though and no problems with any pains or soreness. I have a new recommendation; Switch the pedals to these ones Race Face Chester Pedal Black, One Size . I can't believe how much better they feel with the light hikers I'm using to ride right now. 2018.08.05 Update - 550km + Still loving this bike. Everything is working pretty good, and I’ve had it off road and off trails a bit. At just around 500km I did get a flat front tire; Luckily I was near home as I didn’t have a patch kit with me. A thorn went right through the tire between the tread and punctured the tube. I probably picked it up off road, but returning to hard surfaces pushed it through the tire. The good news was it was the front tire, so easily replaced, but instead I fixed it with a liquid tire sealant that I’ve had a round the house for a couple of years for my regular bike. I’m always testing something so I’m happy to report it worked like a charm, 50psi no problems, i’ve since hit very rocky trails and regular roads for another 80km and it’s holding. I switched the saddle again way back and have settled on the “Planet Bike Men's A.R.S. saddle”, and I’m finally happy. I’d recommend when assembling to use a Thread-Locker on the screws. While I ride some bumpy trails and off trail, even regular vibration seems to be able to loosen just about anything. I’m just about to apply a thread-locker to all the screws. Maybe it’s east coast weather, as the humidity has been very high, but I feel my chain didn’t come well lubricated and after 300km it was already sticking and rusting… did a temporary fix and it’s good right now, but I plan to take it off and do a proper job as soon as I can. Will probably replace with a more rust resistant chain. The shifter, like all index shifters it seems, needs periodic adjustment, but I’m happy with it. It would be cool if electric bikes used electric shifters since they already have a great power source. It only seems right for an e-bike to use an electronic shifter, and l would love the reduced maintenance. The rear carrier (Topeak Super Tourist) I got for it has worked out excellent for me, great to have that. I use it with the MTX Trunk Bag DXP, which has been fantastic. Waiting to try it with other accessories, but so far the trunk-bag has been all I need. I occasionally need a lock so I can go hiking and leave my bike. If you want to use the basic locking approach which locks the rear-tire through the center of the frame, because of the battery you will need quite a large U-Lock if you use one of those. The great ABUS Granite X-Plus 540/160HB300 will just reach and it has a 300mm loop, the shorter more standard 230mm one will not fit. Even with the 300mm u-lock, you will still need another lock to secure the frame to some immovable object as in the basic high security 2 lock approach. The frame is large, and with the battery, the mounts provided to attach these locks to the frame will not work on this bike, so you’ll have to come up with your own carrying solution. The 85cm ABUS Bordo 6500 folding lock is also just a few cm short to use in this fashion also. The larger one will almost certainly work. This bike works easier with chains or cable locks given the design. Cables and cable-locks are OK for light security only, but good ones are bigger and heavier than most people want to carry. My LCD Control Panel kept losing the current time, I thought it needed a new battery, but unlike the manual and seller says, my control panel does not have a replaceable battery that’s accessible. I asked the vendor about that, but they never got back to me after saying they would check. The good news is after a few hundred km, my control panel started working correctly. Not sure if internally the rechargeable battery they use finally changed from the battery on the bike, or if they use a super-capacitor to retain the memory, but whatever the case it is now working correctly. I can now remove the main battery for a week, and the control-panel will still have the correct time. I still have not got around to doing a formal range test for my typical riding, but I did make a trip of 51km (31.7mi), and I still had quite a bit of battery remaining (battery gauge is not accurate enough to report the real remaining capacity). I did baby the battery a bit at the beginning, but I’m pretty sure this battery is good for 60-65km if not more. So much depends on riding style, rider weight, and terrain, but I’m happing with the basic range I’m getting on the battery. One thing to note; if you buy a second battery for the bike, it will likely come with a different key, so you’ll have to keep two different keys handy. This is unfortunate, but understandable given the way the battery locks into the frame. I was thinking about getting a faster e-bike or changing the gear-set for when I had to travel on some main roads, but adjusted the max-speed of the controller through the control panel to 40km/h and I was like a kid on Christmas. That was just what I wanted and it was like I had just got a new bike. That little bit made all the difference, and on a fresh battery it is heaven. .... to be continued ... ... show more

    • Exactly the Bike I was Looking For
I’ve now had this bike for 6 months and have over 2,400 miles on the odometer. That said, considering what I know about this bike now, I’d buy it again today, in a heartbeat. It’s an excellent bike and suites my needs exactly. Before finding this bike on Amazon I tried several bikes in local shops to understand the fundamental features. I got this bike for exercise and for my short commute to work. I needed a bike that could accommodate my bad knees, ruined by athletics and years of running on hard pavement. I am unable to effectively ride a regular bike in the area where I live, which is very hilly (Seattle area). On a normal bike (my 15-year old mountain bike) I can’t transfer enough energy to the pedals to get up the final street to my house, my knees don’t allow it. This bike takes the edge off the hills but still allows me to minimize or turn off the assist when I don’t really need it. I don’t use this bike off-road as a mountain bike. I use it for riding on paved roads and urban biking/walking trails. There are two basic types of electric bikes, cadence sensor assist mechanisms and tension assist sensor mechanisms. The latter is the newer technology and tends to be much more expensive. However, a bike with cadence sensor technology and a throttle are much better suited for a person with bad knees like mine based on the test rides I did on various bikes. Now to the bike… The descriptions, stats and reviews in the listing are spot on. It’s a heavy bike, but electric bikes are heavy. That starts with a stout frame to take the additional stresses inherent in electric bikes. Take that heavy frame, and then add a ten pound motor and a nine pound battery and you come out at about the 57 pounds stated by the seller. My bike, now outfitted with a Topeak rack as recommended by the seller, a good tool kit/flat repair kit and a few extra additions to the handlebar area comes in at about 63 pounds. However, for riding, when I add a trunk bag to the rack (with an extra jacket, a stout lock, a small first aid kit and some extra cold weather gear), a single clip-on panier with my serious rain gear (and room for groceries), and a water bottle; my bike clocks in at about 78 pounds before I get on it. I weigh about 215 so the combined weight is starting to push three hundred pounds. My typical ride is about 20 miles. I regularly go on 30+ mile rides and have gone on rides of over 40 miles without exhausting the battery. As I previously mentioned, I live in a very hilly area. If you live in flatter areas your distances could presumably be further. It all depends on how you use the bike and how much of your own power you can contribute to the ride, and of course, your weight. I find on longer rides I tend to be more “battery aware” and take measures to preserve the battery so there’s enough charge left to make it up my street. I have exhausted the battery only once, fortunately that was about 50 feet from my driveway. I’m 6’1” and the frame fits me very well. I have very long legs so I have the seat post extended to its maximum height. I would expect that this bike would feel comfortable to some several inches taller than me. The suspension is good, in the seat and the front fork. This bike’s motor is powerful and, if you want to, you can easily speed up long hills at 20 mph. The initial setup of the computer allows you to set a maximum speed of higher than 20 mph (beyond street legal in most of the US) but there’s really no point to it since the gearing is not suited for speeds in excess of 22-23 mph. While I’m on the subject of speed, the limitation of 20 mph only applies to the motor, at 20 mph it stops its assist. On downhill coasts, because of the mass of the bike, it is easy to attain speeds of over 40 mph where the road and traffic conditions allow (be careful). As for traffic, this is where this bike shines compared to others. I live in a fully developed suburban area and am always sharing the road with cars. The real test of an electric bike is being stopped at a stop light, pointed up a steep hill, in the middle of a long line of cars in a left-hand turn lane. With the throttle I find that I move through the intersection just as if I’m another car, with no lag, and moving right with the traffic. The lithium battery at 48V and 13Ah holds more charge than batteries on most commercial electric bikes. That extra power translates to more responsiveness and longer ride times. As the battery discharges, the “intensity” of the assist will diminish somewhat. I typically sense this at about the ten-mile stage of any ride. The battery also has a USB port on which I’ve used a few times to charge my phone during a ride – a great bonus when you need it. I have kept detailed statistics about rides and the charging of the battery. After over 120 charge cycles I’ve found that the recharge process takes about 13 minutes per mile ridden or about 3.2 minutes of charge time for each minute ridden. I invested in a second battery which I found to be a good decision. With each battery currently at just over 60 charge cycles I’ve seen no degradation in performance. As for electricity cost – it’s about a penny for enough charge to travel 5 miles. So the charge cost for a forty mile ride would be 8 cents. The computer is mounted on the handlebars and provides feedback on assist level, speed, and odometer and information about the battery status. I use, and rely on, the first three items. As for the battery status information, it is pretty sketchy. I can get back from a 40-mile ride and still have 2 of 4 bars of battery capacity left according to the computer (I don’t). It also tries to tell you how much capacity remains at a given time at your current work load and assist level – but it really doesn’t. I’ve found that I can “feel” the status of the battery with greater accuracy than the information provided by the computer. Bars (out of 4) remaining should give me an idea of how much battery capacity I have left. Here’s what it’s told me (distance traveled): 4 bars remaining – up to 15 miles, 3 bars remaining – 12-17 miles, 2 bars remaining – 13-41 miles, 1 bar remaining – 23-41 miles. This means that at 14 miles traveled I might have 2, 3 or 4 bars of battery capacity left. This type of information is not useful. There must be a better computer out there. It would also be useful to show the current battery voltage and the amperage being drawn by the motor at any given time – that would be very meaningful so someone looking to conserve their battery usage. What I’ve added to the bike: The Topeak Super Tourist DX rack recommended by the seller was an excellent choice. I finally added a Topeak trunk bag and have clip-on panniers for when I need them. The existing headlight is fine but in dark and sometime rainy conditions I find I need more light. I’ve added a 1,000 lumen headlight for conditions that warrant it. I’ve added bar end mirrors, necessary for urban driving among cars. I’ve added a splash guard in front of the bottle cage (MudX) and an extended splash guard at the end of the back splash guard (home made). These have made a big difference. After my first flat at 400 miles I upgraded to Marathon Plus tires. Changing the rear tire on this bike is quite a task so I wanted to minimize the need for doing that again. I upgraded the rear disc brakes to Avid BB7 brakes (180mm rotor). I found that the constant braking needed in my neighborhood (hilly with most intersections uncontrolled) made me feel that the stock brakes were not suited for the stresses of my biking conditions and the mass they were stopping. I will eventually move these brakes to the front wheel and put Avid BB7 brakes with a 200mm rotor on the rear wheel, this will allow access to the inside caliper adjustment with a tool. Problems: The walk assist feature is set to about 8 mph, this is way too fast and cannot be changed. As assembled in the factory the left and right brake cabling was reversed. It was suited for locations where you drive on the left side of the road. This was easily fixed. At about 300 miles the controller failed. This is an electronics box that sits under the battery. It acts as the interface between the motor, the battery, the computer on the handlebars, the cadence sensors on the pedal assembly and the throttle. It was replaced under warranty at no cost to me. I have discussed this with owners and techs at electric bike shops and have learned that controllers occasionally fail early in their life (like many electronic items) and if replaced, the chances of another failure are slim. The failures tend to be a glitch in the manufacturing of the controller. No stars off for that. Service: The seller (Daniel of DJ Bikes) is very accessible when needed, helpful in providing information, and very responsive when problems arise. This bike can be serviced at virtually any bike shop that deals with electric bikes. Expectations: Unless you have assembled a bike before I would recommend that you have a bike shop do the initial assembly or check out your assembly. I found that I had incorrectly over-tightened the front fork assembly. A tech can also provide guidance on how to do “on-the-fly” disc brake adjustments which are occasionally necessary. If you buy this bike you should be prepared to learn about basic servicing and adjustments. Disc brakes need adjusting and tweaking from time to time and you should learn to do that on your own (or find a friend that will do it). Likewise, the derailleur will need occasional adjustments. What I Would Do Differently to the Fundamental Bike Design: 1. I would look for a computer that provides better feedback on the battery status. 2. I would consider a different gear cassette or a larger front gear to allow more power to the rear wheel at higher speeds. I did a lot of research before buying this bike, and as I said at the beginning of this review, I would buy this bike again knowing what I know now. It’s an excellent e-bike. The statement below the bike’s description on the Amazon page is absolutely correct in my opinion: “You will not find a better deal on a high-performance low-cost ebike anywhere.” I have not been compensated by the seller and have no affiliation with him except as a satisfied customer. ... show more
