I like it good buy never got disappointed it goes and goes over 2 hour ride mx350 my son is 51 pounds 7 years old with lithium ion batteries and variable throttle and controller upgrade.

I like the extra power, but it is difficult to find other gears that will mount easily in this motor's shaft.

Is good product gracias

The motor came on time. However, the plug is broken. Good thing my husband knows how to fix it, but what a disappointment. I'd return it if we didn't need it this weekend.

Well, just function tested it and works. I am using this on my razor mx350. The size of it is pretty much the same as the stock, but stronger. The only thing that sucked was the fact that who ever assembled it put the wires backwards, so the motor was spinning the wrong direction. I had to pick all the glue they placed on the wire out just to be able to pull them out and place them back in the right spot. The paint job on the bracket isn't the greatest. It easily chipped away. Not only that, it was a slight pain to screw in the bolts due to the paint getting inside the threads. Just waiting on a new controller. Once completed, I will possibly do an update.9/28/22 Update: New controller has been tested and works great. The motor is doing awesome. FYI, 2 of the motor screw holes is threaded. The other 2 holes are not threaded and will need a nut to keep it in place. Do not use just the 2 threaded ones only as the torque of the motor will slowly bend the bracket upwards. Other than that, when racing against my youngest who weighs 60LBS on his MX350 and my MX650 stock who weighs at 160LBS, he is going faster than me at top speed by approximately 1mph.Suggestion will be to aftermarket the batteries to extend the ride time for this motor.

Lasted me a long time. With great power to size it would pretty much fit in anything. While still having some nice torque. Its still going even after it being through torture. Would recommend.
