The Magnum Cosmo is a budget friendly option in our popular Cosmo series. The Cosmo has a light low step frame with a fully integrated battery. The power system is 48 Volts running on a 500 Watt motor and a 10Ah battery for the range and power you need to run errands or go on a relaxing bike ride.
The heart of the Magnum Cosmo is the integrated, long-range 48V / 10Ah / 480Wh Samsung battery that powers rides up to 40 miles long, depending on variables like body and cargo weight, terrain, wind direction, and pedal assist level.
Designed and built with the city and commuter cyclist in mind, the low-step frame design is a breeze to mount and dismount, and it comes in stylish colors with a sleek, integrated battery.
