This style of electric bike positions the rider in a laid back position for comfort and aerodynamics. Cranks and pedals are usually mounted out front on an adjustable boom vs. directly below the seat tube and saddle. Instead of sitting on a saddle, most recumbent ebikes utilize a canvas chair that supports the bottom and back of the rider; some even have adjustable headrests. Recumbent bicycles are usually set up as tricycles with two wheels up front and one in the back (called tadpole trike), or two wheels in the back with one up front (called delta trike). There are a few unique recumbents that use two wheels like a traditional bicycle, making them easier to lean and turn but less stable to mount.
