Eunorau Flash 2.0 Full-Suspension Fat Tire Electric Bike

The EUNORAU FLASH 2.0 is a full-suspension fat-tire electric bike designed for commuting, recreational riding, carrying a passenger, and extended-distance travel. Its 6061 aluminum-alloy frame combines an 80mm-travel front suspension fork with a rear spring shock and 20 x 4-inch CST tires.

Powered by a 52V 1,000W Truckrun mid-drive motor producing up to 220 Nm of torque, the FLASH 2.0 uses torque and speed sensing to provide responsive motor assistance. It comes standard with a 52V 16Ah battery and supports two additional compatible batteries for longer rides.

The manufacturer lists a range of up to 65 miles with the main battery, up to 135 miles when the optional second battery is added, and up to 220 miles with all three batteries. The FLASH 2.0 also features a Shimano 8-speed drivetrain, four-piston hydraulic disc brakes, BC281 LCD display, thumb throttle, integrated lighting, and a 440 lb total payload capacity.
