A high-step frame on 26 x 4.0 in fat tires gives the Jasion Thunder Pro a stiff, sporty riding position for snow, sand and rough trails. It pairs a hub motor rated 1200 W sustained and 2000 W at peak with a 1040 Wh battery and a 227 kg load rating.
Highlights
- Hub motor: 1200 W sustained and 2000 W at peak, with 115 N·m of torque, a twist throttle and cadence-sensing pedal assist.
- 1040 Wh battery: 52V 20Ah, rated by the brand for up to 145 km on the lowest assist level and 72 km on the highest. A full charge takes 7–8 h; 15 to 80% takes 5 h.
- Speed and gears: a top speed of 56 km/h by the brand's figure, with a Shimano 7-speed drivetrain.
- Suspension and brakes: a hydraulic fork with lockout, a soft-tail rear shock and hydraulic discs on 180 mm rotors front and rear.
- Load: 227 kg maximum, with a rear rack for groceries, gear or a pet carrier; the bike weighs 37.4 kg.
- Connected and lit: a phone app, headlight, brake light and turn signals, a thick saddle and a colour display.

Good to know
- Range is the brand's figure; speed, hills, rider weight, tire pressure and cold all change it. How to estimate your range.
- Ships free anywhere in Canada (no P.O. boxes).
- One spec table on Jasion's page lists the motor at 1800W; the rest of the page gives 1200 W sustained and 2000 W peak.
