Overview
The ZorixBike R8 is a fat tire electric bike styled after a vintage motorcycle, built around a 1500W peak brushless motor and a 48V 20Ah removable battery. It targets riders who want a commuter and trail bike that looks distinct from the usual mountain e-bike shape.
Marketed with speeds up to 31-35 mph and a battery rated for as much as 80 miles, real-world range depends heavily on which of the four riding modes you use, with throttle-only trips landing closer to 40-55 miles. The bike ships mostly assembled, and ZorixBike's customer service comes up repeatedly for shipping replacement parts fast when something fails out of the box.
- 1500W peak brushless motor, 90 Nm torque
- 48V 20Ah removable battery, up to 80 miles rated
- 20 x 4.0 fat tires with front suspension fork
- Dual mechanical disc brakes and daytime running lights
Who it's for
Fits adults and older teens who want a fat tire commuter with motorcycle styling rather than a standard mountain e-bike look. Less suited to taller riders since more than one reviewer needed a seat or handlebar extension to get comfortable at 6 feet.
Pros and cons
- Strong torque for hills and dirt trails
- Removable 48V 20Ah battery for indoor charging
- Fast replacement parts when something breaks
- Four modes cover throttle and pedal-only riding
- LCD display or controller has failed for some buyers
- Seat and handlebar height run short for tall riders
- Electronics underneath sit exposed to debris
Performance notes
The 1500W peak brushless motor and 90 Nm of torque are meant to handle hills and loose terrain, and the 20 x 4.0 fat tires add traction on dirt and gravel. Four modes (pure electric, pedal assist, push, and pedal only) plus a 7-speed drivetrain let riders trade range for speed; one owner at 219 lbs reported hitting 31 mph on flat ground. Stopping comes from dual mechanical disc brakes, and a front suspension fork with a padded seat is meant to absorb bumps, though seat height was a recurring complaint for taller riders.

Frequently asked questions
What speed does the ZorixBike R8 actually reach?
One reviewer at 219 lbs reported hitting 31 mph, matching the lower end of the bike's 31-35 mph rated range; heavier riders or hillier terrain will likely see less.
How far will the battery last?
ZorixBike rates the 48V 20Ah battery at up to 80 miles, with 65-80 miles under pedal assist and 40-55 miles on throttle alone; actual range depends on rider weight and terrain.
Does the R8 come assembled?
It ships about 90 percent pre-assembled with video guides for the rest, though buyers say the printed instructions alone are harder to follow than the videos.
