The kart is responsive and drives very nicely. High torque and fast response even at low speed. What is nice in this project is that the parts were not modified irreversibly, making possible to restore the hoverboard and the kart back to their initial factory functionality.
The kart can reach speeds of up 25 km/h with standard settings or up to 40 km/h with Field weakening activated. For enthusiasts, it is a great platform to learn about electric mobility, programming, control design and electronics.
Since we will keep the rear brake system, some of the kart screws will be re-used to attach the hoverboard. It is a good advice to store all the removed components from the kart in the case you want to revert the kart back to its original shape.
Attach the Hoverboard
The kart is mounted on top of the hoverboard. The key of this mounting is a U shaped bracket that I made from an aluminium straight bar.
On each side, the U shaped bracket is secured with 4 M5 screws. 2 screws to secure the bracket to the hoverboard and 2 screws to secure the bracket to the kart.
From plywood we can cut the floor of the kart. To ease the process, use a piece of cardboard to get the shape and dimensions right. Use the cardboard shape as a template to cut the plywood as shown in the picture.
Once the plywood shape is ready I glued few reinforcement pieces under the kart for extra strength. Finally, I painted the plywood in black.
Connect All the Electronics
In this step, add all the necessary electronics:
- add the hoverboard electronics and battery
- connect the pedals
- add buttons and LEDs
- add connectors for mainboard flashing and sideboard flashing
