Adding a bell or a splashguard to a bicycle wouldn’t be enough of an improvement for Dave Schneider, writing for the electrical engineering magazine IEEE Spectrum. Schneider decided to modify his bike into a DIY, human-electric hybrid. Using a battery from a wrecked Toyota Prius, some lathe work, and some elbow grease, Schneider’s bike can easily go 20 miles per hour and seamlessly switch back and forth from human to electric power. The total cost was about $750.00. The bike might not do everything that a car can, but it’s cheaper and better for the environment, too.
What was the best improvement you’ve ever made to your bike?
