NBPOWER 135mm Dropout e-Bike Conversion Kit 48V-72V 3000W, 100km/h Speed, Alarm Lock

The media could not be loaded. This is my first product/customer service review that I have done in many, many years. However, this being my first, high powered ebike build, wanted to share my experience with NB Power's product and customer service.As with most upcoming technology, there were a number of "hiccups" with this build, that have been troubleshot and resolved. This was a learning experience for me, as these builds do take a certain level of mechanical knowledge to complete properly. NB Power's excellent customer department was there for me every step of the way. Amazing service.I purchased this 3000 watt kit from NB Power and a 72 volt triangle battery from another manufacture in order to save a few dollars. A big mistake on my part.... battery not compatible with kit. 2 weeks later, a battery recommended by NB Power was purchased and works/worked flawlessly. After new battery was received and installed, a "30H" error appeared on the display screen, with no hub motor function. I reached out to NB Power's customer service department, and after several trouble shooting procedures, it was determined that the controller was at fault. With constant contact from Anne regarding shipping information, a new controller was sent, received and installed. New controller did the trick with power to the rear hub, but display would not read MPH or any other viable information. Again, with the assistance of NB Powers' technical department, we were able to troubleshoot the issue and problem was resolved. I felt that Anne and the technical support team shared the same passion of finishing the build as I did. Even with the 12 hour time difference, many of my questions were answered after I assume their technical department was closed for the day. Amazing and first class customer service.As stated in previous reviews, this 3000 watt kit has surprising strong torque and speed. Will knock you off on your back if you don't show the throttle respect. Personally haven't taken the PAS past 5 (out of 9). Have reached speeds to 35 MPH in no time. I do feel this bike is capable of 50 MPH... way to fast for me.In conclusion, some time and finances were involved for me. I didn't mind at all knowing that this could be a challenge. NB Power was excellent from start to finish. They provided out standing communication and backed their product with confidence and pride.

So far so good. Okay, wannabe mad scientist here. I'm planning on building an ebike from scratch, and I decided to use this system as my drivetrain. So far, I'm super impressed. While, it can be confusing to set up, it wasn't allllllll that hard, and we figured it out. Tho, watch out for that pop when you plug the battery in. Someone needs to warn ya about that. But, other than that, I am thrilled with this system. I have a 48V 33ah battery from a dead scooter, and it seems to work fine. The controller display made it surprisingly easier than most bikes to make adjustments. Which gives one a lot of confidence in their setup. I'm also pleased to report, they emailed me before shipping to verify the specs and settings, so they could preset them up. I like that it came with a throttle instead of that silly push button. I have yet to figure out the alarm stuff yet. My only advice to the seller is, please print better pictures of the setup. It was hard to see the cable colors. Also, I've noticed a few extra cables ports. Not sure what to do with those? But, other then that, you've provided me a fine product, and if I need to upgrade the battery, I'll come here first.

The motor is amazing, it has a great solid feel and it's extremely fast and torquey. However the kit just leaves the feeling of unnecessary bloat meant to justify a $600 price tag. If I could have bought the motor by itself I would have had plenty of money to buy what I actually wanted. I could have got a VESC controller, some electric brake levers and a throttle.I don't need a built in lock feature with two key fobs because no one's going to steal a bike that looks like it has a bomb strapped to it on an extremely populated college campus.I don't need a pedal assist sensor because I'm doing an entirely chainless build with no pedals.I don't want a terrible controller that looks entirely different from the one that's in the lackluster diagram, which is labeled different than the one in the preview photos. A terrible controller that is barely programmable, the fact the description has the audacity to call it "smart" is laughable. A terrible controller where you can't even change the acceleration mode from duty cycle to amperage so I don't really every time I try to come out of a stop. A terrible controller that doesn't even take full advantage of the current that can be pushed through through the motor (which is probably why there isn't a connection for the motor's temperature sensor).The motor is great, it feels like amazing quality. It has a temperature sensors and hall sensors, two sets of each in fact. If you can find the motor by itself, and you have a decent knowledge of how to build EVs, buy it and order everything separately. If this is your first time building an EV, sure it's okay and it is nice to receive everything in one package.

The media could not be loaded. Purchased this item to upgrade my e-scooter with a more power motor. The installation was relatively simple, but unfortunately the controller display did not work, and since I waited a few months before starting the project, all I could do was purchase "another new one" from them for $107. Once installed I bench tested the upgrade. To my dismay, the motor had a death wobble that nearly shook it off the table. Thinking I installed it incorrectly, I double checked the mount, all washers, Level checked the motor from the top & side, then retorqued the nuts. The second test went no better. I used a caliper to find the wheel was warped almost .20inches. the quality of the uploaded video isn't great, but that scraping noise is the tire rubbing as it runs past the rack. They were quick to get back to me. There response, "I let our engineer to check the video ;The motorwheel spokes loose ,You find bike shop to fix it ;Usually after ride some time , the spokes loose cause the motorwheel not found ; you tighten and adjust is ok ;I have yet to find a loose spoke, heard back from them, or even had the chance to ride the thing yet............

48Vバッテリーで実際に使用中の実体験として普通に70kmの速度が出るので、ベースとする自転車はディスクブレーキ仕様の自転車を選んだ方が良いと思う。多分キャリパーブレーキでは止まれない
