Excellent E-Bike I’m extremely impressed with this e-bike! It arrived well packaged, was easy to assemble, and has been a lot of fun to ride. The bike feels solid and well built, and the electric assist provides plenty of power when you need it. The battery life has also been great for my rides. I especially like how smooth and comfortable the ride is. The controls are easy to use, and the overall quality is much better than I expected for the price. Customer Service has been GREAT!! **Very happy with this purchase and would definitely recommend it to anyone looking for a quality e-bike at a reasonable price!

Fantastic e-bike! Watch some YouTube videos for assembly but it's pretty simple except for the seat which should be installed with bike upside down. The six nuts are difficult to screw on because the bolts are too close to the frame to get a wrench or nut driver on. Leave all the nuts loose and move the seat until your nut driver or socket will fit over the nuts to tighten. Also, the really nice seat was too low for me and I'm only 5' 10". My knees came up too high while peddling so I added six aluminum spacers between the frame and seat and now it's very comfortable. The seat is not adjustable unfortunately. Anyway the throttle alone can run the bike at 28 mph alone without peddling which I love. I biked about 20 miles yesterday and the battery finally went from 4 bars to 3 bars so I don't know how far you can go using up the battery yet but it looks pretty good. The bike is very comfortable and lower to the ground than our previous Aventon e-bikes so it's much easier when you come to a stop or take off. The motor has a lot of torque and will pop up the front wheel from a dead stop if you hit the throttle too quickly. It's much easier to get the bike on a bike rack on the vehicle hitch. The price is great for what you get.

This bike is absolutely amazing. You’re able to unlock classes from 2-3. 3 being 28 mph, 2 being 20+. It’s fast and super fun, it handles very well and I can tell they really put their craftsmanship to this bike. It’s durable and worth the money. It’s actually affordable as well. Thank you for making such an amazing bike!

I have been using the bike for a few days now. The assembly process was not easy at all. Mine, in particular, had a problem, and I couldn't put in all the screws needed for the seat. It doesn't change much, but in the long run, it might affect the bike. Besides that, the bike works fine, the battery until now lasts more than I expected, and it is super fun to ride. I'm planning to take the bike to a bike shop so they check that everything is fine, and this is a general advice if you are planning to buy it

This ebike is a mix of good news and not-so-good news. Keeping in mind that the price was $720 (good news), expect a few areas of cost cutting and inattention (not so good). I'm in California, so maybe this is just for local sales but the bike has a sticker behind the "seat tube" that states "Class 2 ebike, limited to 20mph". Not exactly as advertised. I decided to register the bike as a "moped" to avoid issues with the crazy and constantly changing California ebike class system. It's a simple, one-time $28 registration with several benefits and a few requirements that I meet. A note to TST...how about a "MOPED" setting in the software. 30 mph, headlight automatically on with power up, persistent turn signals. Overall the classic (retro) moped step through frame, bench seat, integrated battery, mounting for a top box, 20x4 tires and full suspension are exactly what I was looking for. So, good news. So, now some observations.... Documentation Quality: Not so good. The user manual has QR codes printed on the front page. One is supposed to go to an assembly video, but goes to an unrelated 27" bike model instead. Use the video on the Amazon page instead, it's pretty good. The QR code to the Android app goes to "Orbital Sports" and definitely download this, connect it with Bluetooth, and look around in the device settings for ebike class (good news). BUT...the included printed "User Manual" is mostly about assembly and is completely useless for a User. This "User Manual" lists recommended service but has nothing about how to accomplish even the most rudimentary tasks (like changing a tire, more later). Keys: not so good...one of the two keys had broken plastic. Fixed it with super glue, but it shouldn't come this way out of the box. Paint: several areas were scuffed or scratched out of the box. Disappointing. BTW: Google translates the Chinese characters on the battery decal as "Battery Decal" :) Assembly: good news...fairly easy, good selection of tools included. Not great tools, but good enough and most of what's needed. Motor: advertised as 1500W, sometimes 750W. Advertised 32 mph, sometimes 28 mph, my reality is 26-27 cruising and occasional 28 with enough runway on level ground. Enough for my needs. Battery: advertised as 48V-15Ahr special for the 1500W motor, with 40 mile range in throttle mode. 1500W at 48V would require an ideal 31.25A from the battery...unlikely. In my experience the 40 mile throttle range is more like 20-25 with noticeable slowing at lower battery levels. Uphill sag is extensive, falling from 24-26 to 14-16 on a freeway overpass (not much of a hill). Gears/Shifter: good news...Shimano 7 speed, not their best but still quality. Brakes: good news...C-Star hydraulic discs, effective but the calipers need centering to keep them from rubbing. Also a little spongy after a couple months so a bleeding kit is a good idea. (nothing in the "User Manual" about either) Pedals: nothing good news here. replace. Controls: good news...effective but reposition everything. Brake levers, shifter and control panel are too high. Best if they are inline with your arm and natural to use. Turn Signals: nice feature but self-cancel after about ten seconds; not nearly long enough when stopped at a light or in a turn lane. Need a least 90 seconds, or a manual cancel. Brake light: also nice feature, not a traditional dim/bright but instead the tail light flashes. OK... Headlight: not so good...almost no illumination at night and barely visible during the day. Replaced it with a much brighter unit with daytime running light. Chain Guard: crank arm hits the chain guard, a little bending of the bracket solves this. Seat: not so good for me (6'1"-185lbs); front seat is short, narrow and collapses to the seat base under my weight. Same for back seat. Replaced the front seat with a custom seat that fits my posterior and doesn't bottom out. Replaced the back seat with an adapter for the top box. Seat Rail: good news...remove the rear seat and it's a perfect place to mount a top box. Gonna need an adapter and the three holes for the rear seat are really convenient. Rear Shocks: depends...they look like coil over damper, but the "damper" is just a slide with no damping. Adjustable pre-load is some good news; the web pictures don't show it but it's there and pretty good for this price point. They come with the preload all the way up (stiff); probably because they advertise the bike to carry a passenger. If you ride solo and aren't 450 lbs then the "shocks" are useless since even adjusting the pre-load to zero gives NO compliance from the springs. It's basically a hard tail for a solo rider (not so good). I replaced both rear "shocks" with a pair of air adjustable units from MEROCA (purchased on Amazon). Still dialing them in but so far it's a big improvement; makes the ride MUCH more comfortable and improves control. Tires: not so good, but maybe just for my application. Tires are very knobby, noisy, bumpy and THIN. Back tire flatted within the first month of riding on paved streets. Replaced both tires with Ultraverse Road Dominator tires (purchased on Amazon) and HUGE improvement. Also learned that removing the rear wheel requires disassembly of the battery connector in the downtube compartment to access the motor connectors to the controller, since there is no intermediate connector from the controller to the rear hub. (the bike was $720 so...short cuts) (also nothing in the "User Manual") Throttle: really not good news. Typical thumb throttle on the left side. It worked fine for the first couple months but recently has introduced an interesting quirk. With the bike stopped, power on but not touching the throttle, the bike will take off at full speed by itself. First time it just ran into a pile of fertilizer bags and I thought maybe I accidentally touched the throttle. Second time it almost shot me into a busy intersection and I know I didn't touch the throttle. Pulling either brake lever will stop it. Now it happens randomly so I keep my hand on the brake lever whenever the bike is stopped with the power on. This might need a replacement throttle, or maybe a complaint to the NTSB, haven't decided. In summary the not-so-good news is about even with the good news, and there is the throttle thing. If it's toy it might not matter, but think twice if you plan to use it for transportation or give it to a child. At this price it's a decent starting point if you want a project and have the skills and equipment, but NOT as a "buy it and ride every day safely" purchase. I'm keeping it, modifying it and using it just about every day for commuting and errands. Better for around town (5-15 miles round trip) than my van, especially with gas prices skyrocketing. BUT...stay tuned for more on the "death wish" throttle.

Excellent Bike with solid frame. Easy to assemble, especially with youtube tutorial. One slight issue with bike seat bolts but customer support was quick to help and send out replacement.

This bike has been very good to ride and eye‑catching enough that my neighbor complimented it. I’ve taken it out on the trails often and it is fun to ride it. I even ended up buying a second one for my wife, and she enjoys hers just as much. The technical support team has also been very responsive and helpful throughout.

Ton of fun! Bought 2 for wife and me. I think the difference between these and more expensive bikes is fit and quality. Love these but be advised you’ll need to be handy enough to adjust brakes etc. Overall these are great value for the money. Unlocked top speed is 27-28mph. Only have 36 total limes on them. Minor adjustments needed, brakes squeak which is a bit of a pain to fix but for $600 what can I say? Great value for the money and a ton of fun to ride.
