The Magnum Cosmo+ is the road ebike in our popular Cosmo series. The Low Step frame has a fully integrated battery to give the Cosmo+ better balance and a low profile. The power system is 48 Volts driving a 500 Watt motor and a 15Ah battery for the power and range you need to run errands or go on a relaxing bike ride.
The heart of the Magnum Cosmo+ is the integrated, long-range 48V / 15Ah / 720Wh Samsung battery that powers rides up to 50 miles long, depending on variables like body and cargo weight, terrain, wind direction, and pedal assist level.
The wide Kenda 700 x 50c tires are comfortable, durable, and great for commuting and city uses. The larger wheel diameter and wide cross-section make them efficient, fast and comfortable.
