Why should the legs get all the fun during a bike ride? Let’s ask that another way – why should the legs do all the work on a bike ride? The truth is that the arms get a workout too, but now retired surgeon Lex Van Stekelenburg has devised a concept that will truly put the arms to work.
He had designed the 4StrikeBike, which in addition to the conventional leg-powered drivetrain, also calls on the rider to use his/her arms to help provide power. This is done by turning the handlebar like a second set of pedals and crank. The hand pedals can be locked into the highest position to provide a more stable stance to let the legs do the work as well – and this allows the arms to be used to provide that extra bit of power.
