My son is 13 and is interested in making anything/everything electric. He has taught himself so many things based on searching the internet and watching YouTube. He saved his own money to buy this motor so that he could make a traditional Power Wheels F-150 have more power (and surprise the neighbors). Well, this motor was great. He is a tall kid, so it's so it's funny watching this teenager roll around in a Power Wheels meant for a 4 year old. Now he needs to upgrade other parts in order for this to be a functioning vehicle (tires, battery, etc.) The motor is perfect and has everything he needs to make this function. I will post additional updates (and pics/videos) once he upgrades the frame/tires/etc.Thank you! AW and SW

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.

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.

Thank you

This is a huge electric motor! Please proceed with caution..It's a wonderful beast of a motor...Looks proper; but a monster she is!

Written by Sean Vogelsang. Bought this set up for a Razor MX650. I had to mod a lot of things to make it work. The wire on the motor has to come out the side (modified) the screws on the rear plate are in the way for the razor sub frame. I wish they recess the screws like the factory motor. (I modified this issue) had to cut the bottom bracket off on one said because it hits the frame. And I had to grind and drill a hole in the rear end to make it fit correctly. Powered by 2x 6s lipo 48V and makes the razor mx650 so much fun!! This motor is decently fast, maybe to fast for your average kid. It’s to fast for my 38 year old brother, he won’t ride it because I slid across the grass coming in hot from the street on this thing, lol!! Just buy it, it’s not to expensive and it works great. But you do have to modify a few things to make it fit for your MX650 razor scooter.

As noted by others the most frustrating part is the lack of documentation. You have to reverse engineer by taking the controller apart and following the wires. Even then it's a bit of luck to figure it all out. Once you wire the controller correctly it's an impressive DC motor/Controller for a DIY project. This motor has a lot of kick. Very happy with result, and has been great for the first couple days using it on a DIY go kart I've been building.Addendum: After figuring out the wiring I ran across the above picture of a similar product. Surprisingly, it appears to be the correct wiring diagram - correct number of wires, correct wire color, but use at your own risk. Hope this helps save another buyer some frustration. Good Luck!

Works very well. The battery does get hot pretty quick sometimes but that doesn't bother me too much. Very powerful.

Had to find the wiring guide in the other listed review, and then figure out the speed switch wiring after googling it. Use for upgrading a 24vdc razor kick scooter, and powering it with (3) 18Vdc power tool batteries. Swapped out sprocket, and was easy to change. Insanely powerful (easy to wheelie and will throw off a 170lb rider) and fast (up to 25-30mph easy), great runtime (est 10mi or more distance). Motor runs very cool temp. Excellent value, would work great for an electric gocart.
