Real-world output varies with rider load, terrain, traction and battery state.

Every figure below is labelled with where it comes from, so a manufacturer’s claim never reads as a measurement.
Real-world output varies with rider load, terrain, traction and battery state.
Range varies with terrain, assist level, speed, rider load and temperature.
Brake condition, tire pressure and surface grip directly affect stopping and handling.
Check storage and vehicle loading if frequent lifting is part of ownership.
Use lower gears on climbs to maintain cadence and reduce drivetrain load.
The Thunder Mountain F750 is a full-size fat-tire electric bike built for riders who want stronger hill assistance, long-range battery capacity, and stable handling across city streets, gravel paths, and mixed surfaces. Its Bafang G060 rear hub motor is rated at 750W and up to 85 N·m of torque, paired with a 48V 20Ah LG lithium-ion battery (960Wh).
Thunder lists a maximum range of up to 150 km under favourable conditions. Real-world distance depends on assist level, rider and cargo weight, hills, temperature, wind, tire pressure, and stop-and-go riding. The 26 × 4-inch Kenda Krusade Sport tires add stability and flotation on loose or uneven surfaces, while the MOZO suspension fork helps soften potholes and trail chatter.
Compared with the Thunder Leisure F500 and Folding Step-Over F500, the Mountain F750 uses a higher-output 750W motor, more torque, a larger 20Ah battery, and full-size 26-inch wheels. Choose it when climbing support, range reserve, and planted handling matter more than compact storage.
Logan hydraulic disc brakes with 180 mm rotors provide controlled stopping, while Shimano 7-speed gearing lets riders adapt their cadence when pedalling with or without assistance. A thumb throttle and pedal assist support flexible urban and recreational riding.

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.
