WOOSTARMotorcycle Speed Controller 24V 250W Replacement for Electrical Scooter E Bike Bicycle Tricycle Brush

Overvoltaged the razor 250w motor to 36v so I bought this controller for that purpose. Way better than the stock controller especially love the variable throttle. Does get a little warm but not too warm. Then I decided to upgrade the motor from 250watt to 350watt for more power and speed and controller takes that quite well too. Does get warmer than before but not hot at all. Please note that this 36v 800watt controller is NOT waterproof due to no silicone around it so make sure it's in a dry enclosure to prevent damage to the controller. Easy to wire up, Blue wire is positive to motor, yellow is negative to motor. Will buy again in future.

I used this controller to add proportional throttle to my kid's dynacraft 24v UTV vehicle. It took a little research to get it working but so far it's been great! There are no instructions included and all the labels are in Chinese. Thankfully, I was able to find an English pinout diagram for a similar unit on Google. That combined with a little reverse engineering allowed for a successful install. I used an electric ATV hall effect throttle peddle (red 5v, black GND, green 1-4V) for throttle control. I repurposed the original dynacraft accelerator peddle for a break peddle with one NO contact connected to the yellow and black break lead. It has two red/black lead for break lights. I used one to activate a relay that disconnects the motors from the controller and applies a break shunt.

I bought an electric quad and the controller broke within a day.No help or support from rosso motors. They just wanted me to buy a new controller at $70.At $13 this was amazing value.This does not support the three stage speed limiter that the one on the quad did, but other than that it was a simple replacement and the kids have been tearing up the dirt ever since.

I purchased two of these for a home project. Neither one of them came with a wire diagram of the plugs. I have worked with similar controllers in the past, so with some time I figured out what each plug was (there are stickers on the plugs that tell you what the plug belongs to) After I had it all hooked up to my system, the motor plug won’t supply the proper voltage. My multimeter won’t pick up any voltage as I adjust my throttle. However the blue wire to ground gives +21v and the white wire to ground gives +6v. I believe that there is something wrong with the output to the motor plug. Both my drives have this same effect. So I either have this hooked up wrong or this product is for a different type of application that should be better labeled.

I wired this to a modified MX350 Razor. I had to do some significant soldering to get it to be plug n play for the bike. I didn't want anything to be hard wired. Not a single plug fit so I had to change them all out. The throttle was the only tricky part since the original is 4 prong and this one was 3. Other than the significant alteration for it to work, it runs like a charm. Thanks.

Seems to be working as intended. I ran into an issue where my led display on my throttle was staying illuminated even with my key removed. This throttle has been operating perfect with other modules of the same brand. Took a second to spot it, someone at the factory flipped the leads on the "power locks" (blue+red wire plug) once swapping leads in this plug the led screen turns off with key now. I read a few questions and reviews with this same issue. That's the fix. 😎👍🏻

Update; 6/12 it is still holding up, it does get pretty hott after 20 mins of use on my bike setup. I’m running a 750wMotor&36v12ah I hope it does not fail prematurely due to heat. But so far so good 😊Nice that it has a brakes plug, front and rear lights plug. Controller is not in English but refer to the pictures for proper wiring. I will have time to test it out this weekend and make sure it functions properly.

Working great in my scooter. Pushing a 24 volt 500 watt motor to 36 volts! Easy to hook up. Doesnt get too hot even pushing my 200lbs on my Rad2Go scooter! I took the wires for throttle out of connector and soldered the wires for a better connection than just a crimp! Don't want to lose connection on that!

Posted through letterbox with a thud. Not what it says. Wrong wiring, this has a 3 cable lcd speedo, lap, time,etc set up and an extra single black cable,also yellow n blue motor cables very thin and normal pair of thick with different plugs on 4 sets of extra wires, I hope this makes sense.

It gives power to the throttle but not the motor I swapped lead to lead so I know that are right the yellow and blue motor leads are not getting power so the motor won't work but there is power going to the throttle

Does the job exactly. Connector labels were strange but easily worked out.

Unfortunately I wasn't able to use it as I intended :(

Perfect I’m running 62v battery’s on this on my quad works really well
