By far one of the most visually striking bicycles we’ve come across in a while is the 4 Strike Bike by TSG Essempio. The innovative bike features the ability to pedal with both hands and feet at the same time for complete body movement. For those that want to only focus on one pair of limbs at a time, the crankshaft has a special freewheel system that allows the bike to be used with the legs alone. Whether or not the concept catches on waits to be seen, but the design is certainly intriguing if not a bit perturbing.
