Review: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 Read more

Review:just finished this build from NP power via Amazon and went very smooth....the performance from this 72 volt system is almost scary ....smooth and fast!...the order was on time and NP Power was great to deal with..... No issues! and the the performance of modifying my own bike with this setup truly outperforms what you can buy off the shelf. Read more

Review:I bought a 2000w kit for my son's heavy duty mountain bike, as the previous 3 kits were not quite powerful for hills. After he had it put together, I was the first one to test it for speed and safety: 1. fast, definitely not for beginners 2. easy to control 3. great for the price 4. stealth, you can still take it on bike trails if you go slow 5. not that much heavier than 500w or 1000w last but not least: I recommend motorcycle safety gear. Good and professional seller, 5 stars Read more

Review:Buying a product from this company is no different than dealing with an American business. You can talk to them using WhatsApp before, and after your purchase which allows you to request express shipping. I chose express for an additional $120, and received my e-bike kit in less than a week from overseas. The box was delivered by FedEx in good condition, and inside everything was packed well. This build uses a new 2021 Schwinn Al Comp. It has an aluminum hydro formed frame, front/rear mechanical disc brakes, shimano shifters/derailleur/gears, 27.5in MTB tires, suspension forks upfront, and rear hardtail to allow room inside the frame for the battery later on (using rear tire rack temporarily). Bought the bike already assembled at a store that starts with W and ends with mart for $240 total. I had to remove the plastic spacer from the kit for the disc brake so that the motor’s wire had more clearance, and wouldn’t get caught on the screws (picture attached). The backpack, and bungee cords are temporary until I build a housing for the battery that fits in the frame. I am using a 72V 20ah Li-ion battery with a 50amp BMS, and XT60 connector that I purchased on Amazon for about $600 from a seller in China ("Grade A" cells but they're generic). Most of you know this, but as you drain the battery your precious voltage also goes down, and before you know it you have to increase the system power level (1-5) so that you can maintain the same speed/torque. When I have a fully charged battery with all 72+ volts, motor power level set to 5, a flat road, and light wind I can achieve a speed of 43mph according to the LCD, but that number might be 2mph over if radar speed signs are correct--> me: 217lbs + bike: est.95lbs.Yes, the motor/controller get hot when you're using throttle only for at least 15 miles at an average speed of 25-30mph, but so far it seems to operate just fine, and I can place my bare hand on the motor without discomfort so I guess it’s probably a normal amount of heat considering the total weight, and constant throttle usage. Also, hills are a joke to me. On power levels 4 and 5 I was able to climb a very steep hill, throttle only, that was entirely grass which kind of gives you an idea of the torque level. You can have offroad fun similar to a small displacement gas enduro in certain situations/ long the motor and controller last before getting super hot from just air-cooling is another question, but if you stay at 3 (power level I use most) you'll probably be alright. Now, to explain why I gave this kit 4.5 out of 5 stars. It did not come with rim tape which is absolutely necessary before applying the tube and wheel so I used some electrical tape I had. When I was applying the "rim tape" I noticed that one of the holes for the spokes had a sharp metal edge piece/point protruding up that would definitely puncture the tube once you put weight on it so I had to break it off with needle nose pliers. I checked each of the spokes, and one of them was loose, and I had to tighten it before beginning the installation. The manual that comes with the kit is ok, but it should include more detailed information that is kept up-to-date. For example, in the manual there is a picture with labels for the wires from the controller, but the kit you're using does not have wires that exactly match the picture, which isn't a big deal, I was able to figure it out after comparing stuff. For some reason the LCD (SW900) appears to only have 3 digits for the wattage display even though the max output of the motor is at least 2,000W which would require 4 digits to display accurately, and the numbers that do show up seem a little random, jumping from 848 to 436 to 674 even though the throttle input hasn’t changed, and there's also no battery voltage display. It would be nice if the manual had a spec sheet at the end with all the P# settings/values listed for the SW900, in order to double-check the pre-configured factory settings. I could be wrong, but perhaps this kit should have 2 torque arms instead of one to make sure the dropouts do not snap from prolonged use at the highest power levels. Last thing, there’s a slight metal brushing/grinding-ish sound from the motor that you can only hear if passing very close to a fence/wall, and it could be totally normal. Overall, I am happy with this purchase, and would buy another kit from them if I ever wanted to upgrade. SW900 original custom factory settings for my bike: P01-1 P02-2 P03-72 04-0 05-1 06-27.5 07-46 08-100 09-0 10-2 11-1 12-3 13-12 14-35 15-63 16-91 Read more

Review: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. Read more

Review:This motor paired with the 72v battery is crazy powerful and smooth! @ 210lbs I was able to cruise at 45 mph with traffic no problem. With gas prices currently near $3 a gallon this will nearly pay for itself within a few months of commuting to work on it. I will post a long term review down the road for those interested. Anne from customer service was very helpful as well as soon as the order was placed she reached out to help me customize the kit to my liking and adjust shipping details. If youre gonna buy a motor this is the way to go. Read more
