Customer Reviews for 48V DC 1800 Watt Electric Motor with 9Tooth #8 Chain Sprocket and Mounting Bracket for Go Karts Scooters & E-bike

Had installed 3 of them already on mx650 razor not much modification is needed only to remove motors 2 washers and put the bolts back on everything else is plug and play.

I made a custom mount to put this on a mountain bike. To be honest it's all rigged up and looks trashy, but I'm to blame for that. This is a really beefy motor that'll spin up real fast. However it's doesn't have a lot of torque. If your going to put this on something that propels a human(I assume you would), then your going to need a really low gear ratio to get moving. You'll loose a bit of top speed but this motor is so fast I wouldn't worry about it. I like that it has many optional wires on it for things such as lights, reverse, different speed levels, and more.

I did test the unit and it does spin, no wiring diagram but there are images and tips on YT if you search brushless speed controller. You need to use a jumper or on/off switch on the connector marked "lock" I would also recommend using a 30 amp switch on the + side of the battery connector.

Worked well to upgrade the motor on a razor electric dirt bike. Arrived on time and everything worked well. Happy customer!-SM

It works good but haven't try on bike yet, easy plug and ply connections, all works as describe...

The motor looks good, but I did not test it yet. I am very disappointed that I never received the chain shown in the picture.Edit: I spoke with customer service twice, and was finally helped out the second time. My 3* went to 4* because she was just great. I tested the motor and it runs very well. If you don't care for the chain, get this motor.
