Jasion Thunder Pro

What the Jasion Thunder Pro is built for

The Jasion Thunder Pro is a commuter e-bike, built for daily rides to work, errands and city streets.

It has a 2 kW (2 kW peak) motor and a top speed of 35 mph (56 km/h).

It carries a 1,040 Wh battery and a stated range of up to 90 miles (145 km) on a charge. Real-world range is usually lower than the rated figure: it falls with throttle use, hills, cold weather, rider weight and higher assist levels.

The Jasion Thunder Pro has full suspension.

In the United States the Jasion Thunder Pro sells for $1,099, below the median of $1,499 across 230 commuter e-bikes with a US price, among the more affordable models. That is $1 per watt-hour of battery.

Where the Jasion Thunder Pro may be ridden

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 2 kW motor is above the 250 W limit and its 35 mph (56 km/h) top speed is above the 25 km/h at which assistance must stop. A model above those limits is treated as a moped there, with type approval, registration and insurance, unless the brand sells a version set to the European limits.

Jasion Thunder Pro safety certification

The brand states that the Jasion Thunder Pro is certified to UL 2849.

UL 2849 is the US safety standard for the whole electrical system of an e-bike: battery, charger, motor and controller tested together.

New York City allows only e-bikes certified to UL 2849, with batteries certified to UL 2271, to be sold or rented there; California requires e-bike batteries to meet UL 2849 or EN 15194 from 2026.
