Peak output and torque are manufacturer ratings; terrain, rider load and battery state affect real-world performance.

A mixed-terrain e-bike with 85 N·m torque, a 705.6Wh swappable battery, 26 × 4-inch tires, 80 mm front suspension and NFC controls.
Peak output and torque are manufacturer ratings; terrain, rider load and battery state affect real-world performance.
Range varies with assist level, rider load, hills, temperature, speed and tire pressure.
Brake adjustment, tire pressure and surface grip directly affect stopping performance.
Height ranges are only a starting point; reach, inseam and saddle position should also be checked.
Pedal-assist response is cadence-based, so mechanical gear selection still matters for comfortable climbing.
The OKAI Ranger EB50 is a fat-tire electric bike built for commuting, recreational riding and mixed terrain. Its 750W nominal / 1000W peak BAFANG rear-hub motor produces 85 N·m of torque and is paired with a 705.6Wh Samsung-cell swappable battery.
OKAI rates the EB50 for up to 45 miles (72 km) of assisted range. The manufacturer’s U.S. configuration can reach up to 28 mph (45 km/h), while permitted speed and configuration depend on market and local rules.
26 × 4-inch fat tires and an 80 mm RST suspension fork provide comfort on rougher surfaces. Tektro mechanical disc brakes, Shimano 8-speed gearing, a touchscreen display and NFC unlocking add everyday utility.

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.
