Electric kick scooter conversion battery box

thingiverse

This is a conversion of an old Yedoo Wzoom kick bike and an old hoverboard into an e-scooter. Just sharing it if someone has an old bike and wants to convert it. The hoverboard battery needed a case, so I made one. Not super happy about the design, but it's functional and really fun. Good range with a 6-year-old driving it. The acceleration is way better than my Xiaomi M365, but the top speed is 19 Km/h. It climbs all hills you throw at it with a small driver. Parts from the hoverboard are the motor, battery, charger, and motor mount. Then I bought a new controller on eBay (36V ebike controller dirt cheap) and a throttle. The battery box is mounted in the screw holes from the back brakes and strapped against the frame in the front. The motor is mounted with the removed mounts and a steel plate against a 40x40 item rod. The item rod is screwed at an angle into the frame (original hole) to take the twisting loads from the side-mounted motor. Then the rod is just strapped against the frame that supports the item rod. When assembling, the battery needs some protective foam in the box to prevent it from shaking apart. The steel plate welded in front of the battery box needs to be slightly tilted forward; I thought it was screwed into place but it wasn't. Holes for the charger and fuse are removed and need to be fixed with your chosen connectors. Printed in PetG, 4 perimeters, 60% infill, supports in the screw holes. Screws: wood screws (2x 4x30-40), wood screws (8x 3x14 about), and 2 M6 screws. Happy riding, and remember to use a helmet.
