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/terrains...how 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 ... show more

    • 40MPH flat, 48 mph down hill w/ 72 volt battery.
Color: 29inch Rear
I've built a few ebikes before, and if this is your first it will be tricky. There really aren't any instructions and you should have good tools and a bike stand. I knew that going in so it's no problem. I paired this with a hardtail 29er, 20 ah 72 volt battery and it rips! I'm 200 lbs and full charged can get me about 38 mph. slight downhill or lighter person easily breaks 40. Plenty of power. The main thing they could improve is with the pedal assist sensor. When you pedal a bit, it counts it as max and goes max power of that level. I guess they'd need a torque sensor or cadence should work, but it's a bit annoying for it to suddenly take off. I have over 600 miles already and it has worn the tire down but no issues. ... show more

    • Impressive
Color: 26inch Rear
With this kit I get my custom e-bike to hit 53mph with a hill on a full 72v battery (maintains 45mph on flat ground). Does get hot after a while and would recommend hubsink and statorade. Says it’s for 135mm drop outs but I needed to spread them apart a few mm to get the hub to fit.

High quality kit less power that expected but with a shunt mod it does well 48 mph after shunt mod 40 without and slow take off without but it is nice 180c windings this motor could probably take about 4000 watts but nbp motors are really good quality and pretty much the best so you get what you pay for ... show more

1)Rim arrived bent but only on the single of a double wall. NBpower Anne whatsapp response "Engineer says is fine" You will need rim tape and you will need to file down burrs leftover from manufacturing. 2)Kit seemed second hand, disheveled, products not in original packaging and bread ties astrewn. Nbpower Anne says "Is okay" 3)Display only shows wattage output to three (3) digits instead of four (4) NBpower Anne says "engineer says is okay" 4)Display has a max Amp setting at 40 amps NBpower Anne says "engineer says this does not matter" .. of which is partially true as the Display setting ignores any setting regardless of setting it to 1 or 40. I had specifically asked about this before purchase and was assured it was adjustable when I brought this point up NBpower Anne said "Buy cycle analyst V2" I asked why I would have to buy a better Display to get the features this one was supposed to have and was told "it's better". Grin technologies stopped producing the V2 Display and I am discouraged that I should have to supplement the kit with a $150 more to achieve stated capabilities. 5)Controller MQCon 7245 is a well built product with 18 mosfets, 100v capacitor but is obviously programmable to have customized limits by vendor; however the specifications say 45 Amp continuous rating of which I can only produce 40 amps peak and 25 continuous on numerous batteries. NBpower Anne says "enginner says no problem" when I asked why I cannot achieve 45 amps regardless. The numerous reviews expounding the great support and knowledge of NBpower encouraged me to buy this but my experience differed. Unless it's only documentation- that's generic- and an encouraging everything's okay regardless of the problems and inaccuracies You may be tempted to purchase elsewhere. All connectors do fit and the kit is plug and play as well as user friendly if the potential above shortcomings don't matter for your purposes. It is very unlikely I will pursue NBpower for conversion of the rest of my projects that this product was the testbed for. Good luck and happy cycling! ... show more
