Our Verdict
The Jasion Thunder electric bike is a high-capacity fat tire e-bike built around a 1500W peak motor and a 864Wh (48V 18Ah) battery — one of the largest watt-hour ratings available under $1,000. At 1500 watts and 85 N.M of torque, hill climbing is effortless and acceleration from a standstill is noticeably faster than competing 750W models at the same price. The 5-level pedal assist system gives riders fine control over output: drop to assist level 1 and the Jasion Thunder reaches up to 80 miles of range; push to full throttle and expect 35 miles of pure electric range. Either way, the 48V voltage platform and 18Ah amp-hours provide a stable power delivery that avoids the voltage sag common in cheaper 36V systems.
At $949, the Jasion Thunder's cost-per-mile is among the lowest in the fat tire electric bike category. Comparable e-bikes with similar watt-hours and hydraulic brakes typically retail between $1,200 and $1,500, making the Thunder a genuine budget standout. The 26-inch × 4-inch fat tires and front suspension handle gravel paths, sand, and light trails without requiring a dedicated off-road bike, adding real versatility. Integrated lights, turn signals, and Bluetooth app connectivity — features that add $50–$150 to other builds — come standard, reinforcing the value case for daily commuters.
The trade-offs are worth stating plainly. At 82 lbs, the Jasion Thunder requires two people or a purpose-built ramp to load onto a car rack. The 8-hour charge time for the full 864Wh battery means a depleted pack cannot be ready same-day without an early start. The bike ships without a rear rack, fenders, or USB charging port, so budget-conscious commuters should plan an extra $30–$60 for accessories. Jasion offers a 1-year warranty on the frame and motor with 6 months on the battery — shorter than the 2-year frame and 1-year battery warranty standard among premium brands like Rad Power Bikes at a $300–$400 higher price point. No UL 2849 electrical system certification is listed, which matters to buyers focused on verified battery safety. For riders who can charge overnight and store the bike in a garage, the Jasion Thunder delivers top-tier electric bike performance at a mid-range price.
What We Like
- 1500W peak motor produces 85 N.M of torque, enabling steep hill climbing and faster acceleration than most 750W fat tire rivals in the $800–$1,100 price range
- 864Wh (48V 18Ah) battery is among the highest watt-hour capacities available under $1,000, delivering up to 80 miles on pedal assist level 1 per charge
- Dual 180mm hydraulic disc brakes provide consistent, fade-resistant stopping power in wet conditions — a feature typically found on electric bikes priced above $1,200
- 26-inch × 4-inch fat tires paired with front suspension absorb trail, gravel, and sand impacts, replacing the need for a separate off-road e-bike
- At $949 with 1500W, 864Wh, hydraulic brakes, integrated lights, and app control included, cost-per-feature ratio outperforms direct competitors priced $1,100–$1,500
What Could Be Better
- At 82 lbs, the Jasion Thunder requires two people or a ramp to load onto a car rack and is impractical to carry up more than one flight of stairs unassisted
- 8-hour full charge time for the 864Wh battery means a depleted pack cannot be recovered same-day unless charging starts by early morning
- Jasion's 6-month battery warranty falls short of the 1-year battery coverage offered by competing brands like Rad Power Bikes and Lectric at comparable price points
- Ships without rear rack, fenders, or USB charging port — commuters should budget an extra $30–$60 to add these accessories before daily use
- No UL 2849 electrical system certification is listed, which is a consideration for buyers who prioritize independently verified battery and charger safety standards

How far can this bike go on one charge?
It can go 35 to 80 miles on one charge, depending on how much you pedal. If you use the pedal assist and help the motor, you'll get closer to 80 miles. If you only use the throttle without pedaling, it will be closer to 35 miles.
How fast does this electric bike go?
The bike can go over 30 miles per hour at top speed. You can choose speeds between 10 and 28 mph using the 7 gears and 5 pedal assist levels, so you can go slower for easy rides or faster when you're in a hurry.
How long does it take to charge the battery?
The battery takes 8 hours to fully charge from empty. It's best to plug it in overnight so it's ready to ride in the morning. The battery can be removed, so you can charge it inside your house.
Can this bike handle rough trails and sand?
Yes! The 26-inch by 4-inch fat tires and front suspension are made for rough ground. You can ride on trails, sand, snow, wet streets, and even shallow water. The wide tires give great grip and the suspension soaks up bumps.
How much weight can this bike carry?
The bike can carry up to 400 pounds total, including the rider and any cargo. The bike itself weighs 82 pounds. It's built for riders between 5 feet 4 inches and 6 feet 2 inches tall.
