Every figure below is labelled with where it comes from, so a manufacturer’s claim never reads as a measurement.
Real-world assistance varies with rider load, hills and battery state.
Range depends on battery option, assist level, hills, load and temperature.
Cable adjustment, pad condition and wet pavement affect stopping distance.
Test the carry if stairs or frequent vehicle loading are part of daily use.
Use lower gears on climbs to maintain comfortable cadence and reduce drivetrain load.
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.
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.
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.
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. Browse all Thunder electric bikes, compare our e-bike collection, or book local e-bike service.

Unedited reviews from riders across the Lower Mainland — and a few who crossed the border just to see us.
I drove all the way from Seattle to bring my daughter's scooter to ProMechBC and I could not be more pleased with both the repairs and the customer service. I will definitely be bringing the scooter North of the border when it needs some love.
Recently had an accident with my Apollo Go — luckily nothing major was damaged, but it still needed some repair and replacement parts. Service was great, and I got my scooter back within a week. :D
The service was incredibly fast, professional and efficient — they fixed my scooter wheel quickly and the quality of the repair was outstanding. Honest, reliable, professional and fast.
