The HiKeep 20 inch fat tire bike for adults is built for riders who want retro style with smooth, controlled Class 2 performance. A 750W rated brushless motor delivers strong, predictable torque with a factory-set 20 MPH top speed to meet Class 2 standards - twist throttle, pedal assist, and manual pedaling give you three ways to ride. The removable 48V 17.5Ah lithium battery (UL 2849 certified) supports an estimated 35-65 miles of range per charge (actual range varies with rider weight and assist level), so longer days out are always within reach. Full suspension - a front fork working with a rear shock - soaks up bumps and vibration for a smoother, more controlled ride, and wide 20x4 inch fat tires add grip, balance, and stability. Dual disc brakes deliver responsive, dependable stopping power. Inspired by vintage motorcycle styling, this fat tire bike combines a bold retro look with everyday practicality - a distinctive ride for adult men and women aged 18 and up.
