NBPOWER 135mm dropouts e-Bike kit 48V-72V 3000w e Bike Conversion Kit 100km/h Speed,3000W ebiken kit with 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 media could not be loaded.  It would have been nice if they just used the waterproof Juliet connectors. The set up would go way smoother without that yellow block. I opted to use soldering heat shrink to do the connection to the motor from the controller. I justwish they weren't being cheap or they aren't top notch at details, whatever it is I'd suggest finding a company that does have it.Update: so I'm in the middle of actually installing it I realized what another review was talking about. They mentioned filing something and it turned out they needed to file the fork on their bike down because one of the axles is wider than the 135mm measurements listed. Good thing I too own a file so I can make it fit I just want anyone else to be aware of this issue.So in conclusion the flaws are that width of the axle discrepancy and the poor choice in wire components.SECOND UPDATE: THIS THING IS GARBAGE. I ALMOST GOT IN AN ACCIDENT IN THE STREET TODAY BECAUSE THE DAMN THROTTLE DECIDED IT WANTED TO CONTINUE TO ACCELERATE EVEN WHEN I WASNT TWISTING THE THROTTLE AND ACTIVELY BRAKING! I HAD TO POWER IT OFF TO STOP IT. I TOLD A FRIEND WHO WORKS IN BIKES AND HE TOLD ME HIS BUDDY HAD THE SAME CONTROLLER AND PROBLEM. SO CLEARLY IT WASN'T JUST ME. IF ONLY I WERE ABLE TO HOOK UP MY BRAKE CUTOFF SWITCHES TO THE CONTROLLER BUT THESE CHEAP BASTARDS DIDNT PUT THE WATERPROOF CONNECTORS THAT ALLOW ME TO DO THAT. IM DEBATING ON GETTING A COMPLETE REFUND AND DEALING WITH NOT HAVING A MOTOR FOR HOWEVER LONG IT WOULD TAKE TO GET A QUALITY KIT FROM A REPUTABLE SELLER OR SHAMING THESE FOLKS INTO GIVING ME THE CONTROLLER THAY WOULD WORK PROPERLY ON THE MOTOR WHICH SEEMS FINE BTW. THE MOTOR THEY COULDVE SOLD ME SEPARATE AND SPARED EVERYONE THE TROUBLE OF COMPLAINING WHEN THIS ONE EVENTUALLY SCREWS UP.
