Bionic's City-X (City/Trail Cross) is the perfect bike for both city cruising and light trail use. It has a 48 volt rear motor, providing smooth power when you need it. The City-X features Bionic's SensorDrive system, giving the feel of a mid motor but in a rear motor format. The battery is fully integrated into the frame and can be unlocked for removal. The tyres have been specifically chosen to allow good road holding and also good grip in gravel, so they are perfect for New Zealand's rail trails. The gearing is provided by a SRAM 9 speed system and has been configured to allow for a wide range of terrain. Shimano hydraulic brakes come fitted as standard, giving awesome stopping power and sensors are fitted to both brakes to automatically stop the motor when the brakes are applied, making the City-X a very safe bike to ride.
