How fast does the Mars Folding Electric Bike go?

The motor is rated for a 28 MPH top speed, with five pedal-assist levels and a throttle. Range depends on assist level, terrain and rider weight.

Mars rates it for 30-degree slopes with 54 Nm of torque. Riders report strong pull on steep grades, though long climbs drain the battery faster.

Is the battery removable?

Yes. The 48V 13.5Ah pack comes out for charging indoors or swapping, and a full charge takes 6–7 hours.

How small does it fold?

The folded frame measures about 920×520×760 mm, small enough for a car trunk or closet.

How much assembly is needed?

It arrives 250% pre-assembled with tools included, so most of the build is done; you finish the remaining setup.

Is it good for tall riders?

The 20.8-inch wheels and folding frame suit average adult riders. Very tall riders may find the compact geometry cramped.

About the Mars Folding Electric Bike for Adults

The Mars Folding Electric Bike is a 20-inch-wheel fat-tire e-bike with a 500W rear hub motor, a removable 48V 13.5Ah battery and a steel frame that folds for storage or car transport. It runs on throttle or five levels of pedal assist, with a 7-speed drivetrain and 3-inch tires for grip on rough pavement and light trails. The electrical system is UL 2271/UL 2849 certified, which matters for home charging. It suits riders who want a compact, powerful folder rather than a light city e-bike; the steel frame and fat tires make it heavy to carry and pedal unassisted.
