Is the JASION Thunder worth it?

If you want a fat-tire ebike with a 750W motor, hydraulic brakes and a big 864Wh battery at a budget price, it is a strong package. Accept the 82 lb weight and treat the 80-mile range as a best case.

The motor is rated for up to 28 mph in the listed specs, though the product name and some copy claim 30 mph. Expect Class 3-style speeds on pedal assist and throttle.

What is the real battery range?

The claim is up to 80 miles of pedal assist from the 864Wh battery. With throttle use, hills or a heavy rider, expect considerably less.

JASION lists a rider height range of 5'2" to 6'3". The 26-inch wheels and 46-inch wheelbase suit most adults in that range.

It is rated IPX4, which covers splashes but not heavy rain, pressure washing or submersion. Store it covered and dry the battery contacts after wet rides.

What comes in the box?

Expect the bike, the removable 48V 18Ah battery, charger and basic assembly tools. Check the listing for the exact included accessories before ordering.
