Jasion Thunder 1800W Fat-Tire Electric Bike

The Jasion Thunder is a fat-tire electric bike built for riders who want one bike that handles both everyday urban commuting and genuine all-terrain exploration. Its 26 x 4-inch puncture-resistant tires and adjustable front suspension are designed to smooth out rides across city streets, gravel, sand, snow, and rugged trails, making it a versatile choice for commuters who also want to get off the pavement on weekends.

A brushless hub motor rated at 750W with a peak output of 1,800W and 85 N·m of torque powers the Thunder to a stated top speed over 30 mph with pedal assist. The 48V 18Ah (864Wh) lithium-ion battery provides a maximum range of up to 80 miles per charge, while a Shimano 7-speed drivetrain, five pedal-assist levels, and a twist throttle give riders the flexibility to pedal, cruise on throttle alone, or blend the two depending on the terrain.

The adjustable and lockable front suspension fork helps absorb impacts from potholes, roots, rocks, and other uneven terrain, while dual hydraulic disc brakes provide responsive stopping control in a range of conditions. A color display shows speed, battery level, and mileage at a glance, and riders can connect a smartphone to monitor battery status, track rides, and adjust settings. Integrated lighting includes a headlight, turn signals, parking lights, and brake lights, and a heavy-duty rear rack combined with an ergonomic seat rounds out the Thunder's commuting and cargo-carrying capability.
