I've been working with electric bikes for almost 3 years now and as I was browsing my favorite site looking for new ideas I stumbled upon a electric mountain board and started doing research. I started becoming more and more interested in working with rc motors and finally took the plunge making one for myself.
Step 2: Went to the scrap yard and found some aluminum L-channel. This is what I used to make motor mount/bracket piece form.
Step 3: I measured, cut and drilled the holes for the mount using the truck as your template since it will be bolted to the truck using the pre-existing brake mounting holes.
Step 3b: I also cut a v out of the center to allow for the mount to sit flush and allow for side to side movement of the truck.
Step 4: Using pieces cut from the aluminum, a piece scavenged from another project I was able to come up with this mount. ( This will be different for everyone ) Once the mount was made I mounted the motor using the mounting screws that were provided.
Step 5: Using the brake disc provided with the mountain board as a mount for the drive sprocket I drilled the holes and bolted it up making sure there was enough space for the chain to clear.
Disc mount used as mounting plate for drive sprocket.
Step 6: After I mounted the drive sprocket to the wheel I installed the motor side sprocket and the chain. ( NOTE* You need to grind down a flat spot on the motor shaft so that the set screw has a flat surface to lock down on.) Also check for chain alignment before tightening down the set screw.
Step 7: I mounted the controller using industrial 3m velcro as well as the receiver for the wireless remote.
Step 8: After getting everything mounted and ready I hooked up the batteries in parallel to give me 22.2v 10ah and used Velcro strapping to hold it to the board.
