labwork 36V/48V/60V/24V 350/250/500/800/1000W DC Brushless Motor Speed Controller Replacement for Electric Bicycle E-Bike Scooter

So far so good. Bought to repair a Ryobi push mower that had died. Hooked it up and paired it with a thumb throttle controller and it works great so far. Cannot say anything about longevity as I have not had it long but it works well so far.

No instructions or compatability information for older ebikes without built in lights HAD to return

👍

Update: Worked nice for a few days, then quit. Checked all the connections, didn't see anything loose. It appeared to be getting power. Battery was still at 50 volts. Opened up the controller box and didn't see anything fried or anything loose. Not sure what it is, so can't 100% blame this product, but I ordered something else.Just bench testing, I couldn't get it to work at first. I had to cut the 3-wire plug off my old throttle (red, green, black wires) which matched 3 wires on one of the controller plugs so I correctly assumed it was throttle. But the single red wire with the eye lit has to be connected to power too. That wire would go to an on/off switch if you have one. The wheel spun the wrong way so I connected the single white leaning wires together and it spun (without giving it throttle), I disconnected them and reconnected them and it spun the correct way. Disconnected them and leave them disconnected. Now the single red eye lit wire gives it power and the throttle makes the wheel spin in the right direction. Problem solved but a little frustrating.I looked at other amazon ads for similar controllers that had better wiring diagrams and color photos that showed the actual color of the wire unlike this listing. And I read comments and found some helpful wiring info too.

It's a nice product has many applications but the one thing it does need is a wiring schematic without it it's hunting pack to make it work all it takes is one little wrong wire and you can short everything out so you really got to be careful

Being new to the ebike world, and a bmw performance specialist, i had to get more power out of my new ebike. the little 250 watt controller powering a bafang 500 watt geared hubmotor just wasnt cutting it. so after trying about 3 different controllers, frying my display and all my hall sensors, i replaced the sensors, and the burnt up wiring both in the harness and coming out of the hub. I was thrilled to feel this controller unleash the beast i knew that 500 watt motor to be. the three speeds are great for letting my girl ride or for when i take my child for a spin on it. ive been using it daily going on months now and it hasnt let me down once. currently being used on a 48volt battery and when its fully charged it gets out of the hole for real and doesnt heat up my hub hardly at all

Works just fine some wires are confusing but overall great product

The media could not be loaded. Doesn't wort...bad hall sensor. Don't waste money
