Chainsaw Powers Teenager’s Bike
Jared Witmer starts the chainsaw motor on his bike by moving forward. No rope pull needed.
    “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.
