Bionic’s City-X Bike is a versatile 9 speed cruiser which is designed for city and trail use. The step-through frame design makes getting on and off the bike easy while the handlebar configuration allows a very comfortable upright riding position (which can be easily adjusted via a quick-release system). 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. It has front suspension which can be locked for better efficiency on smooth roads or engaged for rougher roads and trail use. The gearing is provided by a Shimano Acera 9 speed system and has been configured to allow for a wide range of terrain. Stopping power is awesome through hydraulic disc brakes with 180mm discs. The City-X is also supplied with fully integrated front and rear LED lighting (which means you don’t ever have to replace batteries), keeping you safe when on the road at night.
