Torque Where the Trail Turns Vertical.
"When the ground tilts up, torque is everything."
The Rambo Roamer 2.0 is a mid-drive all-terrain machine — the one you reach for when the ground tilts up and the trail turns loose. Its Bafang 750W mid-drive puts power through the crank instead of the wheel, so every ounce of torque lands where you need it: climbing grades, crawling over roots, and hauling a loaded rack without bogging down.
Rolling on fat 24 x 4.0 Kenda anti-puncture tires and stopped by Logan 2-piston hydraulics, it is built to wander — up to 48 miles on the standard 48V 15Ah battery, or 65 with the 20Ah upgrade. A Box 8-speed drivetrain gives you the gearing range to spin up anything.
"The Roamer is the climber of the lineup. A true Bafang mid-drive and an 8-speed drivetrain make it the pick when your rides involve real elevation and a loaded rack — power multiplied through the gears, not just pushed from the hub. Efficient, torquey, and built to wander all day."
BUILT FOR RIDERS WHO
- You ride real terrain — steep, loose, rooted — and want mid-drive torque, not just hub-motor push
- You haul gear and want the 300 lb capacity and metal rear rack to carry it
- You value climbing efficiency and want gears to match the grade
- You want range flexibility with a 15Ah-to-20Ah battery upgrade path
MID-DRIVE, NOT HUB
Torque Multiplied Through the Gears
Hub motors push from the wheel at one fixed ratio. The Roamer's Bafang 750W mid-drive works through the crank and your 8-speed drivetrain — drop a gear on a nasty climb and the motor multiplies with you. That is the difference between spinning out and grinding to the top with a loaded rack.
Pair that with fat 24 x 4.0 Kenda Kevlar anti-puncture tires and the Roamer's footprint becomes a platform: dirt, sand, loose shale, and early-season mud handled by four inches of aggressive tread while the mid-drive pushes you through it.
RANGE YOU CAN UPGRADE
48 Miles Standard — 65 With the 20Ah
The Roamer ships with a 48V 15Ah, 720Wh LG-celled battery good for up to 48 miles. Step up to the 20Ah pack and range climbs to 65 — the flexibility to size capacity to how far you actually wander.
Ride in a lower assist mode on the way out and the range stretches further; call on the mid-drive's full torque for the loaded climb home. That headroom is what turns a day ride into an all-day ride.
KEY FEATURES
Waterproof LCD Display
The digital LCD is tough and waterproof, showing power, speed, battery, and mileage at a glance. Its Adjustable Class Setting (ACS) lets you switch between Class 1, 2, or 3 modes to match local e-bike laws.
Box 8-Speed Derailleur
A durable, budget-friendly Box 8-speed drivetrain delivers smooth, reliable shifting across a wide gear range — built to handle rugged riding and keep you in the right gear on every grade.
Metal Rear Rack
The sturdy metal rear rack adds reliable cargo support for hauling gear, groceries, or daily essentials, with durable construction built to handle heavier loads on the trail or around town.
Anti-Puncture Tires
Kenda all-terrain 24 x 4.0 Kevlar anti-puncture tires feature an aggressive tread for superior grip across dirt, sand, and rough terrain, with Kevlar protection to resist flats where you ride hardest.
PDW Fenders
The PDW front fender keeps water, mud, and debris off the rider, and the Mud Shovel rear fender extends coverage for a cleaner, more comfortable ride in wet conditions.
SEE IT IN ACTION
WHY THIS BUILD MATTERS
The Roamer's engineering choices are built around one idea: put the power where it does the most good and let you carry more, farther. Here is why they matter.
Mid-Drive Climbing Power
A hub motor gives you one ratio at the wheel. The Roamer's Bafang mid-drive runs through the 8-speed cassette and changes that ratio every time you shift. On a steep, loose grade with a loaded rack, gear multiplication is what keeps you moving.
Upgradeable Range
48 miles on the standard 15Ah battery, 65 on the 20Ah. Size the pack to the ride instead of paying for range you do not need — or add capacity later when your routes get longer.
Built to Haul
A 300 lb payload, a sturdy metal rear rack, and Kevlar anti-puncture tires mean the Roamer is set up to carry gear over rough ground without flats or frame strain.

Is the Roamer 2.0 a mid-drive or hub-drive e-bike?
Mid-drive. The Bafang 750W motor sits at the cranks and drives through the 8-speed drivetrain, so it multiplies torque through your gears — a real advantage on steep, loose climbs versus a hub motor.
How far can the Roamer 2.0 go on a charge?
Up to 48 miles on the standard 48V 15Ah battery, or up to 65 miles with the 20Ah upgrade. Real-world range depends on terrain, assist level, and load.
What size tires does it use?
Kenda all-terrain 24" x 4.0" Kevlar anti-puncture fat tires with an aggressive tread for grip on dirt, sand, and rough terrain.
