Thunder City 500W Urban Commuter Electric Bike The Thunder City electric bike is a conventional step-over commuter built for paved routes, errands and daily transportation. Its Bafang G02 500W rear hub motor is rated at up to 80 N·m of torque, while 48V Samsung battery options let riders balance purchase price, battery weight and range. Choose the Battery for Your Commute The 48V 15Ah version is listed for up to 100 km, while the 48V 20Ah option is rated up to 125 km under favourable pedal-assist conditions. Actual distance varies with hills, rider load, temperature, tire pressure, assist level and throttle use. Road-Focused Equipment Unlike a bulky fat-tire model, the City uses 26 × 1.95-inch Kenda tires with reflective sidewalls for efficient urban rolling. A MOZO suspension fork, Tektro mechanical disc brakes and Shimano Tourney 7-speed gearing provide familiar bike handling and straightforward maintenance. Thunder City or City RX? Choose the standard City for mechanical brakes and multiple battery options. Consider the Thunder City RX if a fixed 840Wh battery and hydraulic brakes are higher priorities.
