Thunder Step-Thru Electric Bike for Everyday Commuting
The Thunder Step-Thru electric bike uses a low-step frame to make mounting and stopping easier while retaining the components of a full-size urban commuter. A 500W Bafang rear hub motor, thumb throttle and Shimano 7-speed drivetrain support daily travel, errands and moderate city hills.
15Ah and 20Ah Samsung Battery Options
Battery choices are listed for up to 100–125 km, depending on configuration and favourable pedal-assist conditions. Actual range changes with rider weight, hills, wind, temperature, assist level, throttle use and tire pressure.
Comfort Without Fat-Tire Bulk
The MOZO suspension fork and 26 × 1.95-inch Kenda tires help smooth rough pavement while keeping the bike more road-oriented than a 4-inch fat-tire model. Tektro mechanical disc brakes and familiar derailleur gearing also make routine service straightforward.
Which Thunder Step-Through?
Choose this model for battery choice and a simpler mechanical-brake setup. The Thunder Step-Thru RX adds an 840Wh battery and hydraulic brakes. Browse Thunder e-bikes, compare all electric bikes, or book Vancouver e-bike repair.

What our customers say
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.
