Wooden Electric Motorcycle

After my electric wooden bike toy and my reproducible wooden bike, the next logical step was to build this wooden electric motorcycle. I found my local fablab a bunch of unused stuff that worked perfectly for this project: electrical motor, small lead acid batteries, speed regulator and wheelbarrow wheels.

Tools

• CNC router (flexicam)
• 3D printer
• Hammer
• Sandpaper
• Press drill
• 34mm drill bit
• Hacksaw

Material

• Plywood 18 mm (2m x 1m)
• Lumber 40 x 20 mm (length:)
• ABS filament
• E-bike conversion kit
• 2 lead acid batteries 12v 7Ah
• Epoxy glue
• White glue
• M20 nuts and bolts

• Cylindric lumber, diameter: 28mm length: 260mm (for curtain)

Download the dxf if you want to cut the parts directly. I also gave the solidworks files in case you want to modify something.

*Sorry I couldn't load zip and assembly files.

Clean the parts with sandpaper.

Now you can start assembling the chassis. (cf. image)

Be sure that everything works together before gluing. (white glue, wood glue or epoxy)

A big hammer can help but do not break the parts. If it is too difficult to assemble, go back to the sanding step.

• Drill the chassis
• Pressfit the axle in the direction triangle (and glue)
• Cut the direction triangle to ease the lumber passage
• Insert the two lumbers 20 x 40 mm previously marked with the position
• Secure the front wheel with the M20 bolt
• Glue the down bearing on the triangle with epoxy
• Glue the down bearing on the chassis
• Glue the top bearing on the other side

• Draw the part you need and print it (sorry I lost the file, it is just a cylinder with holes)
• Tap the holes
• Screw the sprocket on it
• Screw the whole on the rear wheel
• Place the rear wheel and the chain
• secure the rear wheel with the wooden plates (last image)

• Secure the battery in place
• Screw the motor on the wood
• Secure the controller
• Add the throttle (I adjusted the handlebar diameter)
• Screw the handlebar
• Secure the wires with zip ties

Try it! Stay safe! Add brakes!
