Thunder Pro Step-Thru Long-Range Electric Bike
The Thunder Pro Step-Thru electric bike pairs an accessible low-step frame with the longer-range equipment of Thunder’s Pro commuter platform. Its Bafang G02 500W rear hub motor, 840Wh Samsung battery and upright geometry suit frequent riders who want easier mounting without giving up full-size wheels.
Manufacturer-Rated Range up to 150 km
The 48V 17.5Ah battery is listed for up to 150 km under favourable pedal-assist conditions. This is a maximum claim: rider and cargo weight, hills, wind, temperature, speed, throttle use and assist level can reduce actual distance.
Pro-Level Commuter Hardware
Tektro hydraulic disc brakes, an RST Blaze suspension fork and 27.5 × 2.10-inch Kenda tires provide a more substantial road setup than the standard Step-Thru line. Shimano Tourney 7-speed gearing helps manage starts, hills and lower-assist riding.
Step-Thru or Step-Over?
Choose the Step-Thru for easier mounting and stopping. The Thunder Pro Step-Over offers the same core motor, battery and range targets in a traditional frame layout. Browse Thunder e-bikes, compare electric bikes, 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.
