Review: Long and Fun Journey - 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.
Review: BETTER THAN ADVERTISED - Bad Ass Kit (topgun) BUT NOT FOR THE MECHANICALLY TIMID. You have to be able to think. Pros: When you get this product, you realize it's better than expected. This is a high performance product! Cons: There were no assembly instructions at all. Fortunately, I've been an aircraft mechanic 20 years, so I was able to install everything and even splice my old ebike throttle and brakes into this installation. It worked❗It was still a pain to figure everything out. The whole job took me about 6 hours (taking my time). Advice: be very careful when handling the controller wires (the power terminals) after connecting the battery, because it will shock you or spark even if you have disconnected the battery. Also, once everything is connected, you MUST turn on the display unit and go to system settings (double press "M"), and change the voltage to the voltage of your battery. My bike was sluggish at first, but after changing the settings, it was quick as fk.

### ⭐⭐⭐⭐⭐ Fast, great support
*by K***R on March 15, 2023*

Fantastic! I was coming from 4 generations of 2 stroke bike kits and finally decided to try electric. I even used my electric bike frame for this build (built in gas tank!). Just wow...no comparison at all! First, it makes my bike silent again! And there is no resistance, no noise, and very agile again. The weight is really nicely centered, and the torque makes it wheelie on command. It is SUPER fast (definitely 55+), torquey and fun! I have to say that support is also fantastic, I had one issue with my UKC1 after about 650miles and they got me a replacement fast. Even though they are overseas they are very responsive on whatsapp. I also got some spoke replacements (over 1000 miles on it) but after looking at them very closely this winter I've found that the rim is still very straight, so I'm good to go this season. FYI, I have the 20A battery and get a solid 50+ miles per charge when I average about 25mph. The amount of boosts definitely impacts distance, like any electric vehicle, so ymmv. And it takes my battery about 5 hours to recharge when I'm at about 20-25% left. I'm looking forward to putting another 1000+ miles on it this summer!
