JRAHK BLDC Sine Wave Controller Electric Scooter 60 36 48 72 84V 2000W E-Bike Controller for Bicycle Accessories

Paired this with my 72V 3000W brushless DC motor, 72V 65Ah 35A BMS lithium ion battery; intentionally underpowered the motor capabilities to kept my set up mild for my 7 yr old; will hook up my 50A controller with appropriate battery when he’s masters this. Product works / performs great. Has extra /unneeded lines to use for power source (lights, display, etc. Dimensions perfect for a no cut/tomfoolery installation . Had to switch the signal and ground wire on throttle ; at first thought. Oh man POS ha but checked and all good bike rips 45MPH

Very good controller did my razor. The controller I got with the motor was very slow and non-responsive. This one works like a charm love it.

No stars item does not work

For the price this unit works great and was a good replacement for a burned out 60v Kunray controller. We have about 6 months on it so far, it doesnt get hot and we havent had any issues once we got it all figured out. We are using it with a Kunray 2000 watt 60v motor and a 60v 35ah custom built 21700 cell battery, in a Razor SX conversion. We are using the BASIC functions only: throttle, motor, battery, 3 speed switch and key switch. Depending on which Amazon throttle you use, you may have to rearrange the pins on the throttle connector to make it work; not a big deal, just an extra step. Dont forget to use the learn function or it wont run properly, so read the directions. The first one we received was used and had some of the connectors cut off. We were able to contact Amazon and a new one was shipped out immediately, not sure whos fault that was, but once the new one arrived it worked great!

This controller is a beast. Setup was straightforward and it runs my 1800W BLDC motor with smooth acceleration and low noise. Highly recommended for e-bike or kart projects.
