Motor wattage can differ by market; confirm the exact regional configuration when comparing power or ordering electronics.
Maximum range varies with battery option, assist level, hills, rider load and temperature.
Stopping performance depends on pad condition, tire grip, total load and surface conditions.
Fit should be checked by reach and inseam as well as rider height.
Shift under reduced pedal pressure and use lower gears on climbs to limit chain and cassette wear.
The Rize MD is a mid-drive electric bike designed for riders who prioritize climbing torque and a more natural pedal-assist feel. Its 750W Bafang BBS02 mid-drive motor produces up to 120 N·m of torque, making the motor’s output available through the bike’s gearing rather than driving the rear wheel directly.
The standard 48V 15Ah / 720Wh Samsung battery is manufacturer-rated for up to 43 miles (69 km) of assisted range. An optional 48V 30Ah / 1440Wh dual-battery setup extends manufacturer-rated range to up to 86 miles (138 km) under favourable conditions.
The MD suits riders dealing with steeper routes, frequent elevation changes or heavier commuter use where mid-drive torque matters more than a simple hub-motor layout. Actual range depends heavily on assist level, gearing, rider load, terrain and temperature.

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.
