Thunder Pro Step-Over Long-Range Commuter Electric Bike
The Thunder Pro Step-Over electric bike is a full-size road-oriented commuter with traditional frame geometry. A Bafang G02 500W rear hub motor, 840Wh Samsung battery and hydraulic brakes target longer commutes and frequent daily use rather than compact storage.
840Wh Battery with up to 150 km Claimed
The 48V 17.5Ah battery is manufacturer-rated for up to 150 km under favourable pedal-assist conditions. Actual range depends on rider load, hills, temperature, wind, speed, tire pressure, throttle use and assistance level.
Full-Size Wheels and Hydraulic Brakes
The RST Blaze suspension fork and 27.5 × 2.10-inch Kenda tires balance efficient paved riding with added comfort on broken surfaces. Tektro hydraulic disc brakes provide progressive control, while Shimano 7-speed gearing supports starts and climbs.
Step-Over or Step-Thru?
Choose this model if you prefer traditional step-over geometry. The Thunder Pro Step-Thru uses the same core power and battery platform with easier mounting. See all Thunder electric bikes, compare our e-bike collection, or arrange e-bike repair in Vancouver.

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.
Katie Barber
★★★★★
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.
