NBPOWER Hydraulic Brake !QS V3 205 Motorcycle 17" 18" 19" 21" 72v 5000W Ebike Rear Motorwheel with tire, 72V 100A Sabvoton Controller with PAS and Alarm,Matching (21inch Rear)

Bought in August 2023, I've put more then 1k miles in the fall/winter and it is a very fun kit. It's plenty zippy and has a great top speed. I haven't had any issues with it and the ordering process was smooth. They do contact you to get your options and to verify the motor/tire size and they do a great job at streamlining it. Do make sure to get a battery that can support the wattage that this thing pulls. Although my 80s moped isn't that light it gets it going real quick.

Hi all. Be aware that the NB power does not honor their warranty, and in case of any trouble when contacting their technical support you may receive totally unqualified help (which in my case burnt/shorted the whole system). I purchased the 72v 3000-5000w kit form NB Power for my Sondors Madmods Scrambler. The kit is this Sabvoton 80a controller (SVMC7280) paired iwth NP power's own motor, which they call fatmotor 3-5k. I asked for 4T winding to get more torque than speed (have lots of hills). I have a 72v batttery with 80a daly bms. The pack is built with 160pcs of p421 Molicells (21700) in a 20s8p configuration amounting to 72v 33.6 ah. I installed the setup and the bike was running beatiful for 20 minutes. I was a happy camper. Parked and the next day I tried the bike the wheel had constant drag and vibration (usually damaged hall sensor). Tried both hall sensors, same issue. Contacted NB power and their technician would not believe there was a probelm with the motor, despite the permanent drag and vibration (plus noise during operation, again, typical of hall sensor damage). The NB power technician kept asking to change some parameters and test again, changed ofset andgles several times, nothing helped. He eventually said the bike was working properly (despite drag and noise and vibration) and asked me to test ride it. During the testing immediately as I gave it throttle the display shut off and wouldn't turn back on. I had to connect and reconnect from the battery (I am using QS8 antispark connectors), but it gave a spark. Tried second time, and it gave a spark again, so I disconnected everything and tested my battery first with a multimeter. Battery tests ok, and the voltage matches what the daly bms displays through the bluetooth app. So now I tessted the controller and the positive and negative wires are short circuited. Also by running basic tests I can see the short circuit on the blue and green phase wires of the controller. NB power did not honor their warranty, though it has been on ly 5 months since purchase (just took me a while to build the battery pack, the kit actually worked only for 20 minutes). So beware that when buying from NB power you are taking a chance.

Rim has a great finish, but for as much as you pay you would think it came with spinle ready for mounting.

Ive had this full setup for about 2 years. It was a bit of a hastle putting it together but once finished its a beast. Approx 200 mile range with 8000watt hr battery, top speed approx 60 mph.Smooth ride, sturdy, looks awesome too. Just as good as an electric dirtbike, its like having a second vehicle!Highly recommended, its way better than others Ive ridden.Things to note: be very careful to secure the main power wire away from rear brake roter or it will chew into the power cable.

First of all, Anne was great and very patient, answered all of my questions within 24 hrs and usually within 6-7 hours. Really outstanding customer service. On the newer controllers they switched the colors of the throttle and PAS wires, but my wiring diagram did not take this into account, so I spent a day messing with a multimeter trying to figure out why my throttle voltage was stuck at 0v, and the signal to ground was outputting 2.6V instead of a bit over 1v. turns out I was plugging the throttle into the PAS, which actually matches colors with the throttle. Plugged into the black red and green and I was good to go.Another thing to watch out for is that , in order to access teh settings menu you have to double click the button below the power button. There were no instructions provided for this, and I had to contact Anne in order to find out.

The NP Power 72 V 5000 W hub motor is very fast and I like the quality of all the components.I have only ridden a few miles but I can tell the Sabvoton controller makes the motor very quiet and smooth. The best part to me was the help of the staff after setup. Many thanks to those who helped me!

Anne is great to do business with and their products are good quality.
