NBPOWER 170-175mm Dropout 20inch *4.0 3000W Electric Fat Bike Conversion kit with tire, Sabvoton Programmable Controller, TTFT UKC1 Display, 7- Speed Freewheel, and alram Lock

Paired with a 72v 30ah 50bms tuned controller down to 50amps tweaked a few settings hit 55mph. Faster then I expected only thing I wish I knew was there is no easy way to hook the lights up for the bike

Ive had problems with the controller the second month i had it I tried to return the faulty controller but i was redirected to try fixing the problem instead .they walked me through the problem to try and fix the issue the first time but the problem happened again which isn’t my fault may i add, i reached out to them again but the problem is the controller is not working completely now mind you i have a warranty and they want me to pay for a new one even though i had a bad controller from the beginning watch these folks I wouldn’t purchase from here there scamming folks

I installed it on a 4 year old Radunner. I've been very pleased with the company. Anne was great to work with. She returns all of your emails. Delivery was on time. I love the Bluetooth programmable controller. I use my ebike on very rugged backwoods terrain. This motor has been holding up. I'd do business with the company again.

I connected my battery to the controller n it started to smoke and they won’t give me a refund n trying to make me pay for a new controller when they sent me a faulty one don’t buy

I contacted them through WhatsApp and they were very helpful. They gave me guidance the whole way through the order and gave me advice on the install sense I have no idea what I’m doing and plus they sold me a battery. They are very reliable. The kit is very powerful. If you want a powerful kit get this one. Their customer service is Amazing!

Highly recommended will definitely be doing business with again

Company sells faulty products

I bought just the motor from Anne and so far it has been treating me well. I used a sabvoton 72150 and a 48v battery that I made (200amp max continuous BMS). Thing was able to reach 57mph at 48v. I used statorade to cool it down and two grin's torque arms to keep it in place. I'll update my review should I notice any issues.
