Choose torque or cadence sensing
Torque mode follows how firmly you pedal for natural, proportional assistance. Cadence mode supplies power when crank rotation is detected for easier cruising. A thumb throttle provides power without pedaling up to its configured limit.
- Advanced torque sensor for proportional response
- 12-magnet cadence sensor for easy cruising
- Configurable Class 1, 2, or 3 operation
- Up to 25 mph pedal assist and 20 mph throttle-only

Frequently Asked Questions

Who is this folding e-bike best for?
It suits commuters, RV and camper travelers, apartment residents, recreational riders, and anyone who values low-step access, compact storage, stable wide tires, and a relaxed riding position.
What is the difference between torque and cadence sensing?
Torque sensing changes assistance according to pedal pressure for a natural feel. Cadence sensing supplies assistance when crank rotation is detected for easy cruising. This model lets you select either mode.
How far can it travel per charge?
Magnum publishes a 30–50 mile range. Actual range varies with rider and cargo weight, terrain, wind, temperature, tire pressure, speed, stops, and assist level.
How fast does it go?
The current specification lists up to 25 mph with pedal assist and up to 20 mph throttle-only. It can be configured for Class 1, 2, or 3 use; permitted settings vary by location.
Does it include a rack, lights, and fenders?
Yes. The rear rack, front and rear fenders, front and rear lights, electric horn, adjustable kickstand, and charger are included. A front rack and bottle cage are not included.
What rider size does it fit?
Magnum recommends a minimum rider height of 5 feet. Saddle height adjusts from about 21.75 to 31.5 inches, and the telescopic stem adds cockpit adjustment. A test ride is recommended when reach, mobility, or inseam is a concern.
