NBPOWER 48V/60V/72V 3000W Electric Bike Conversion Kit, 26" Double-wall Alloy Rims, with sine wave programmable controller, Twist throttle with LED Display for E-Bike Conversion Kit.

Only took 7 days to arrive and the Sabvoton controller is a fantastic bit of kit

Really fast.... does 42mph. I like the alarm and electronic wheel lock. 72v Batteries are really expensive but that's nothing to do with this product. If fitting to a normal mountain bike torque arms are a must because there is so much torque it would rip straight out .hydrolic brake are a must...bigger the better. Only complaint is that the Bluetooth connection didn't work to communicate with the controller for adjustment. ... that's why the 4 star otherwise it would have been a 5 star.

good communication and good product.

J'ai bien réussi à monter un vélo électrique avec ce kit. 80km/h validé (je ne peux pas aller plus vite car la batterie que j'ai acheté ne me le permet pas. Seul bémol pour ma part: le système de communication par Usb ne marche pas. Ni avec la clé bluetooth ni avec un câble usb relié à mon Pc....Le contrôleur vendu dans ce kit est un sabvoton 72080 soit 72v 80a (prévoir la batterie qui va avec!!!).
