The Magnum Peak T5 is a full-featured electric mountain bike built for trail riding and everyday adventure. Powered by a 48V 500W rear geared Bafang hub motor, it delivers smooth, responsive performance up to 25 mph across six levels of pedal assist. A torque-sensing pedal assist system reads rider input to provide natural, energy-efficient power delivery that extends battery life on longer rides.
The 48V 15Ah (720Wh) battery provides a range of 30 to 56 miles per charge depending on terrain and assist level. The battery is expandable to 17.5Ah or 20Ah for greater range. The bike rolls on 27.5-inch wheels fitted with CST Patrol 2.8-inch wide tires for confident traction on loose and technical terrain. The front suspension fork includes adjustable preload and a lockout switch for efficient pedaling on smooth roads.
Stopping power comes from Logan 4-piston hydraulic disc brakes, which provide consistent, controlled deceleration in all conditions and prolong rim life compared to rim brakes. Shifting is handled by a Microshift AX 1x11-speed drivetrain that eliminates the front derailleur for a cleaner, lighter setup. An oversized backlit display gives clear visibility in all lighting conditions. The bike is configurable as a Class 1, 2, or 3 e-bike, with the throttle removable for Class 1 compliance. Maximum rider load is 265 lbs. Includes a one-year limited warranty.
