How to Strap a Leaf Blower Engine to a Bike and Go Fast

Step 4 Adding the Spring

I was able to ride the bike at this point, but I didn't get very far: after a few miles of high speed bumps and vibrations, the motor brackets loosened up. After a bit of time thinking up solutions, I ended up buying a spring from a local hard ware store. I rigged up a wire hook to a hole on the bikes fork and a brass hook on the far end of the plywood plate between which the spring can be tensioned. The spring allows for changes and movement of the engine while keeping plenty of traction between wheel and motor.

Seems like you could pretty easily add a foot pedal clutch in the form of a lever that acts upon the whole setup in the opposite direction as the spring. This shouldn't be too risky since it would only be needed at low speed. The problem then would be getting back up to speed. It would make for some humorous one-legged-scootering starts. On second thought, this would probably work better as a hand-lever. What do you think?
