Good kit, great company
Color: 27.5inch Rear
It's a good kit by a great company. I had some issues with a couple of the parts in my kit. However, the customer service was excellent and I got speedy replacements. I installed the kit to a Giant Talon XL Aluminum mountain bike with disk brakes. I added a few things such as 12V converter for automotive grade LED lights, a rack to mount my battery, a full frame bag, and different sprockets. I put a 52 tooth front, and 34-11 tooth rear freewheel on it. This allows low gear to pedal uphill with no electric assist, and also pedal along at a comfortable cadence up to 45 MPH. Just keep in mind you need a compatible rear derailleur and a few extra links in your chain. I would recommend similar upgrades if doing long commutes and night riding. The power is great and on the higher settings will try to wheelie if you're not careful. I paired mine with a Unit Pack Power 72V 40Ah battery. That battery is very big and heavy, makes the bike awkward to maneuver when I'm not on top of it, and required a beefy custom mount. Not the battery I'd recommend for everyone, but I wanted lots of range and it was cheap. The range is 40 to 120 miles. I'm a tall and heavy rider, so me on the bike with battery, tools, lunch, work clothes and water comes out to 330 lbs. I have lots of steep hills and it's been windy lately. Even so, a charged battery gets up to 45 MPH on a slight incline very quickly with no pedaling. This style of riding averages 40 MPH will result in only about 1 mile per Ah. If I pedal along with it and average 35 MPH, it uses 11Ah to go 20 miles on those same hills, so the range is nearly doubled this way. Now a note here, I adjusted my amperage down from 40 to 20 Amps. There was only a slight uphill acceleration loss, but the efficiency went up, and the heat buildup went way down. I tried various set points, and I recommend 20-25 Amps. I think the motor and controller will last a lot longer this way(84V for charged 72V nominal battery X 40 Amps = 3360 Watts!, way over the 2000 Watt advertised rating), and I can confirm the range for 20 Amps is improved at the same speeds. Also note, that if you intend to use this kit over 25 MPH, I strongly suggest you have disk brakes and wear protective gear. I also recommend getting your wheels trued up perfect. if they're wobbling and bouncing it's going to be really bad at high speed. I recommend this kit to anyone with a little mechanical knowledge and OK with putting in some work to get a great end result. As a motorcyclist who also cycles for exercise (since my knees aren't the best when I run a lot), this kit is a perfect in-between which lets me commute to work, get my exercise, and have fun all at the same time. ... show more

Nice Kit, Powerful
Color: 27.5inch Rear
I just finished this and I've only ridden it a couple of times. I had it up to 30mph which is scary fast on a bicycle. I doubt it will hit 40 as I weigh 210 and it is a heavy frame, but I'll update this when I've ridden it more. I used an old steel frame from a cheap 20 year old Murray. I stripped it and replaced every single thing on the bike. It was not designed for disk brakes and that was the biggest obstacle. Anyone building this kit should use a hardtail mountain bike that was designed for disk brakes. I did not hook up the PAS. The control panel has a trip odometer, battery level, speed, Watt, and power level display. It has 5 power levels. Level 5 is Quick. It feels like the front wheel wants to lift when you hit the throttle. Levels 3 & 4 are good for just cruising. I like the full twist throttle better than the half twist my other e bike has, but they are both nice. I've never tried the thumb throttle. I bought the 20 amp hour battery and you can see it fits easily in this frame. It probably wouldn't fit a bike with rear suspension. I think it's a good kit with a heavy duty motor. The rear wheel drive feels better than my other front drive bike, more like a motorcycle. Sweet. ... show more

Great kit but…
Color: 27.5inch Rear
Unless you know are skilled in this kind of thing, it’s not DIY, especially because it comes with vague instructions. I had to find a bike shop that does E-bike conversion to make it happen. Still, so far, it has been great. Living in a place with hills everywhere, I can get around very easily and on flat sections, I can easily go over 30 in fourth gear. I’ve been able to top out at 47 while in 5th. However, it’s best to limit usage of 5th gear because it gets very hot and drains the battery fast. ... show more

3 years 600 hard off road miles later.
Color: 27.5inch Rear
Using with a 52v battery. Put this on a Vitus Nucleus VR frame. Running on some mild off road MTB trails with a few jumps. Has taken everything Ive thrown at it. Ive added magnetic liquid to help cooling though I never had a over heating problem even on the hottest days. I did put a different geared cassette on it. Good stuff. Everything is solid. The only problem I ever had was with the battery connector. The part on the actual battery where the contacts touch were melting/corroding/becoming obligated so and intermittently cutting power. I replaced the connector on the battery and its solid again. Heres to another solid 600 miles. ... show more

All is great with my purchase!!!!!!!!!!!! 4 months later now and I'm loving this kit even more!!!d
Color: 27.5inch Rear
I love this kit!! It was so easy to hook up!! Everything went together so smoothly!! Unfortunately I bought a Voilamart kit and it didn't work. I finally was able to get the Voilamart kit working after replacing the controller which they reimbursed me for so thank you Voilamart. This one works great!! I definitely will be buying more from this seller. I highly recommend this seller!!!! Aaron Update- I just finished building a better battery for my kit. Now it flat out flys!!!! I can cruise at over 40MPH. What a great kit!! Another Update- This kit has worked flawlessly! I mainly just ride on light trails and roads. If you plan on doing extreme off roading than you must get a mid-drive kit or you will burn the motor and controller up. I tried to ride on a really aggressive trail a few weeks ago and my ebike made it but I'm afraid I over heated the motor a few times. It's still working at 100 percent though. When I ordered this kit it took over 3 weeks to get it but was well worth the wait!! Aaron ... show more

Not fully plug and Play. Expect to buy extra parts
Color: 27.5inch Rear
When you order a kit that typically means everything's compatible, plug and play if you will. Apparently that doesn't go for these Chinese motors, the phase wires for the motor and the phase wires for the controller are completely different thickness gauge wires and they have completely different connectors on the ends. So in order to get this to work I have to buy more parts. The so called controller bag they give you is an absolute joke, piece of advice find your own controller bag ... show more

10/10, Best cost/performance, Great support
Color: 27.5inch Rear
Highly recommend this kit. Installation can be tricky for first time people, but definitely can be figured out. Instructions are decent. Support is 10/10, 2 minute response time on whatsapp. Faster than you want (I usually leave it in 3 or 4 out of 5), great range, great torque for hub drive, better than my friends $1k Amazon bikes by a long shot. Haven’t had issues with heat. Little to no noise at all, in fact I like the small noise it makes, feels cool. This seems to be the best route to go if you want a performing e-bike. ... show more
