The Twicycle is an innovative new bike concept that gives both your arms and legs a workout.
A traditional rear drivetrain connects foot pedals to the back wheel, while a second drivetrain connects the front wheel to a hand crank, to allow for hand pedalling. This exercises your arms and shoulders as well as your legs. Right now, the Twicycle is in the prototype phase, but its inventor, Boyan Rista, plans to launch a crowdfunding campaign this summer and price it similarly to other road bikes already on the market.
