Liked it for the price once got everything wired properly. The pdf instructions on the pinouts are not great.A few notes to others: The throttle wires pins are incorrect slots in connector. You have to take the connector apart and make it so black to black. Signal wire in the middle so swap the black and the green wire on the throttle. To take apart connecter stick a tiny screwdriver inside the connector and push the ramp down and pull the wires out.The other tough part for me was figuring out the blue 'learn wire'. You have connect the single blue wires to themselves for the first startup- note it will run as soon as the key is turned on so be ready. Then unplug the wire in the middle of running and it will stop. Now you can leave the blue wire unplugged for the rest of the time. If you leave it unplugged from the beginning the phases will be mixed up and it won't run properly.I had to flip the wheel so the breaks were on the right since the first time I tried the wheel was turning backwards so watch that.I used a 56V EGO battery and it worked pretty nice. I was using a Razor E200 frame and the rear forks were a bit too wide so I had to bend them in a bit. Had to get a bit creative with the breaks and holding the outer drum but not terrible. I didn't use the charge port or antitheft stuff. My son really likes it. It goes about 18mph max and has good acceleration and torque in hills. A gigantic improvement in fun over the Razor E200 and a decent project as intro to eMachines. Good luck.

Had some trouble after reading some reviews on similar products. First to note, those of you having issues with constant speed should note that other products refer to the two blue wire black connectors refer to a "Intelligent Motor Phase Reconition" tool. Disconnect those wires and the motor should stop spinning under power. The twist throttle pot. delivered is DOA. Purchased a thumb throttle and found that if you wire the throttle as show, (5vRef=red, Sense = wht, SenseGND = blk) the motor controller operates the motor very smoothly with a perfect amount of dead band IMO. The seller is obviously repackaging these items and the lack of supporting content deems it 3 stars IMO. Here is a link to the thumb throttle I used, but you will have to add your own key switch.https://www.amazon.com/dp/B09ZQJPD44?psc=1&ref=ppx_yo2ov_dt_b_product_detailsBest of luck everyone!

The box was all torn up the foam that held the wheel was all broken, not all wires are labeled and some wire didn’t match to the cable they were supposed to go, overall wouldn’t recommend
