The FX-510 folding bike accommodates a full size adult up to 125kg and folds up small enough to easily fit into the boot of a car or a small wardrobe. Even though it is so small it still carries most of the features of its siblings in the Bionic stable. It is equipped with a 48 volt rear motor drive system to provide smooth power when you need it. An intelligent sensing system measures how much torque you are applying to the pedals and magnifies this torque by an amount that you control. If you need a break, a thumb throttle is standard on this model and allows direct speed control when you want it. The FX-510 features front and rear suspension, giving it the smoothest ride of any folding e-bike.
