Overview
Jasion sells the Thunder line in three trims, base, PRO and ST, with peak power, range, top speed and load capacity all varying by trim (up to 2000W peak, 90 miles, 35 mph and 500 lb depending on which one you order). All three share 26 by 4 inch fat tires, dual hydraulic disc brakes and a UL-certified electrical system.
The line targets commuting and mixed-terrain riding rather than singletrack, and Jasion backs it with a 24-month motor, battery and controller warranty plus a remote-lock security feature.
- Three trims: Thunder, PRO, ST
- 26x4 fat tires, dual hydraulic disc brakes
- 48V 18Ah battery, up to 80 mile range
- UL-certified electrical system
Who it's for
Fits adult riders under about 400 lb on the base spec who want a fat-tire commuter with real pedal-assist range. One reviewer at 6 foot 6 found the frame too small, so taller riders should check geometry before buying.
Pros and cons
- Fat tires handle sand, snow and city streets
- 7-speed Shimano shifting with 5 assist levels
- Hydraulic disc brakes stop quickly
- 24-month warranty on motor, battery and controller
- At least one reported battery failure after cold storage, with replacement stock unavailable
- Hardware such as zip ties and screws missing from some boxes
- Return policy can cost up to half the price
- 82 lb shipping weight needs two people to unbox
Performance notes
The 7-speed Shimano drivetrain and 5 assist levels let riders dial in anywhere from a 10 mph cruise to a reported 28 mph on pedal assist. Dual hydraulic disc brakes bring the bike to a stop in about 2 seconds per spec, though one buyer's real-world test found the base motor struggled on a steep hill even with assist engaged.
