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.

Parts[edit | edit source]

Board: MBS Comp 95x from MBS Mountainboards.

Motor: Turnigy SK3 6364 from AsiaTees

Sprockets : Scooter sprocket and Motor Sprocket from Electric Scooter Parts

Aluminum pieces: from the scrap yard

The batteries, controller, and throttle were all ordered from AsiaTees

Batteries: Two 22.2v 5Ah lipo batteries.

Controller: 150amp car ESC

Throttle: Wireless 2.4 ghz

Other parts: Wire, electrical tape, wire connectors, nuts and bolts, zip ties, tie down straps.

How to Build[edit | edit source]

Gather your needed parts and supplies. Most important determine which motor you want and what board you want to use. Also you will need these tools. Tools Used: Socket set, Sawhorses, Hacksaw (or equivalent), Hammer, Adjustable wrenches, Hex key wrenches, Pliers, Clamps, Drill and bits, Grinder ( or equivalent), Metal files, Wire stripper, Chain breaker, soldering iron.

Went to the scrap yard and found some aluminum L-channel. This is what I used to make motor mount/bracket piece form.

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.

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.

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.

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.

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.

I mounted the controller using industrial 3m velcro as well as the receiver for the wireless remote.

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.
