Thunder Step-Thru RX Long-Range Commuter Electric Bike
The Thunder Step-Thru RX electric bike combines accessible low-step geometry with the larger battery and hydraulic braking package of Thunder’s RX platform. It is designed for frequent commuting, errands and riders who prefer easier mounting without moving to a compact folding bike.
500W Assistance and an 840Wh Battery
The Bafang G02 rear hub motor is rated at 500W with up to 80 N·m of torque. Its 48V 17.5Ah Samsung battery is listed for up to 120 km under favourable assist conditions; real-world range varies with rider load, hills, temperature, throttle use, speed and tire pressure.
Hydraulic Control for City Riding
Tektro hydraulic disc brakes, a MOZO suspension fork and 26 × 1.95-inch Kenda tires create a comfort-focused urban setup. Shimano 7-speed gearing gives the rider mechanical options for climbs and lower-assist riding.
RX vs Standard Step-Thru
The RX is the better fit when hydraulic braking and the fixed 840Wh battery are priorities. The Thunder Step-Thru offers multiple battery options with mechanical brakes. Explore Thunder electric bikes, browse all e-bikes, or schedule e-bike service 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.

★★★★★
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.
