Go the Extra Mile

Enjoy the extended range Roamer offers. With two batteries operating in tandem, riders can cover longer distances without the need for recharging. This is particularly useful for eBike commuters, touring enthusiasts, or riders who frequently embark on lengthy adventures.

Leisure Riding

With ergonomic features and low-step frame design that prioritizes comfort, Roamer eBike can be a great option for leisure riding. The electric motor helps you cover greater distances with less effort, allowing you explore scenic routes, or simply taking a leisurely ride around town at a comfortable pace.

Dual Battery System

Roamer eBike is equipped with a highly efficient dual battery system for extended range or longer cycling duration. This eBike comes with two 14A batteries, allowing you to enjoy the benefits of increased power and extended rides without the need for frequent recharging.

High Efficiency

The mid-drive motor is located in the middle of the bike's frame, near the pedals. It drives the crank set directly, providing power directly to the drivetrain to optimize power delivery and improve overall efficiency. Mid-drive motors do not create resistance, allowing for smooth and unimpeded riding during regular exercise or when the battery is depleted.

Higher Torque & Faster Acceleration.

The mid-drive motor provides higher torque, which can be advantageous for climbing steep hills or riding in challenging terrain. Due to the stronger torque output of the mid-drive motor, Roamer eBike can more quickly respond to the rider's pedaling effort during acceleration. This makes it more competitive in situations such as starting at traffic lights, maneuvering through congested areas, or requiring quick bursts of speed.

New Biker!

I'm absolutely loving it! What I really dig are the cool design, comfy seat and grips, the bright front light, great tires, and how easy it is to pick up riding, especially since it's my first e-bike. When I reached out to customer service for help, they were super responsive and took care of my issue.

Thrilled with this e-bike

I am absolutely thrilled with this e-bike! The dual battery setup provides an incredible range - I managed to ride a whopping 150 miles on pure pedal-assist mode and still had 50% battery remaining. The BaFang mid-drive motor makes every ride feel like a breeze. I just love it!
