Magnum Cosmo 2.0 Step Thru Electric Bike

The Magnum Cosmo 2.0 is a versatile step-through electric bike designed for comfortable, accessible riding. Its low 16-inch standover height makes mounting and dismounting effortless, while the lightweight aluminum alloy frame keeps the total weight at approximately 65-66 lbs.

The bike is powered by a VIH 48V, 500W rear-hub motor with 750W peak power, paired with a 48V, 624Wh Li-NMC battery seamlessly integrated into the down tube. The Magnum-branded VeloFox backlit LCD display provides easy access to five pedal-assist modes: Eco, Tour, Sport, Turbo, and Boost. A thumb throttle is also included for on-demand power. The Cosmo 2.0 ships as a Class 2 e-bike with speeds limited to 20 mph, but can be converted to Class 1 by disconnecting the throttle or unlocked to Class 3 speeds of up to 25 mph through the settings menu.

Range varies from 25-50 miles depending on assist level, with testing showing approximately 49.5 miles in Eco mode. The Shimano 7-speed drivetrain features a 48T chainring and 11-32T cassette operated by a RevoShift twist shifter. Stopping power comes from Tektro hydraulic disc brakes with 2-piston calipers and 180mm rotors. The SR Suntour suspension fork offers 80mm of travel with a lock-out feature for smooth rides on varied terrain.

The bike rolls on 26 x 2.35 CST tires and includes integrated front and rear lights, full-coverage fenders, a rear cargo rack rated for 55 lbs, kickstand, wide platform pedals with reflectors, electronic horn, ergonomic grips, and a Velo gel comfort saddle. The seat adjusts from 27.75 to 37.75 inches, accommodating riders 5'0" and taller. Total payload capacity is 220 lbs. UL 2271 certified for safety.
