Chainsaw Powers Teenager’s Bike
“I start pedaling, and the compression starts the motor,” he says. “When I hit the brakes, the motor stops.”
Witmer is a senior in high school and built the powered bike for fun. He attached a 41cc Husky chainsaw motor to the rear frame of his bike. He used a bracket that attached to the frame at the side and above the rear wheel. The bracket is also attached to the seat post. A turnbuckle connects the bracket to the other side of the bike wheel.
The Husky had the bar and clutch removed. Witmer attached a DMX bike foot peg to the chainsaw shaft and positioned it against the rear tire.
“The motor adds a little load to one side of the bike, but it’s not too bad,” says Witmer. “Right now, I reach behind and hold the trigger, but I am going to move the throttle to the handlebars.”
Witmer plans to use a twist throttle handgrip. In the meantime, he enjoys it as is. He hit 27 mph with his chainsaw-powered bike and is confident it could go faster.
