Key item features

750W High-Torque Motor with 1500W Peak Output: Powered by a 750W brushless motor with up to 1500W peak output, this fat tire bike for adults delivers strong, steady torque for quick starts and confident climbing - a powerful 750W machine that stays smooth and predictable in everyday riding.
48V 17.5Ah (840Wh) Removable Battery, UL2849 Certified: The removable 48V 17.5Ah lithium battery is UL2849 certified for safe charging and dependable performance, supporting a 30-60 mile riding range per charge with pedal assist. Slide it off and charge it at home or in the RV - a long range fat tire bike that is always ready to ride.
Class 2 (20 MPH) with 3 Riding Modes: Choose pure throttle, pedal assist, or manual pedaling. As a Class 2 bike, motor assistance tops out at a factory-set 20 MPH in line with U.S. Class 2 standards, and the simple single-speed drivetrain means no gears to shift or maintain - just twist and go.
Full Suspension for a Smooth, Controlled Ride: A dual-crown front suspension fork plus rear shock absorbers soak up bumps and vibration, keeping the ride stable, comfortable, and planted. This full suspension fat tire bike delivers confident handling and an aggressive, head-turning stance that stands out from ordinary bikes.
20x4 Puncture-Resistant Fat Tires: Wide 20x4 fat tires with reinforced puncture-resistant construction put a big contact patch on the ground for dependable grip, balance, and load capacity. The extra-wide profile improves traction, stability, and impact resistance for everyday peace of mind.
Reinforced Frame Built for High Torque: The strengthened high-strength frame is engineered to handle the motor's high torque output, offering long-term durability and stable handling for heavier riders and gear loads - with a rugged, muscular silhouette that turns heads wherever you park it.
Safety First, Fully Certified: UL2849 certified electric system for peace of mind. Recommended for riders aged 16 and up; always ensure the front wheel is securely installed before riding, wear a helmet and protective gear, and avoid unauthorized modifications. Top motor-assisted speed: 20 MPH (Class 2).

About this item

Product details

The HiKeep 20 inch fat tire bike for adults pairs bold, aggressive styling with Class 2 compliance: a factory-set 20 MPH top speed, a 750W high-torque brushless motor with up to 1500W peak output, and a UL2849 certified 48V 17.5Ah (840Wh) removable lithium battery, all built into a reinforced high-strength frame. With three riding modes - pure throttle, pedal assist, and manual pedaling - it is an easy-to-control ride that both new and experienced riders can enjoy with confidence.

The full suspension setup - a dual-crown front fork paired with a rear shock - soaks up bumps and vibration for a smoother, more controlled ride, while puncture-resistant 20x4 fat tires add grip, stability, and load capacity. A simple single-speed drivetrain means no gears to adjust and minimal maintenance: just twist and go. With a riding range of 30-60 miles per charge with pedal assist (actual range varies with rider weight and assist level) and convenient indoor charging at home or in the RV, this compact fat tire bike is a head-turning ride for adult men and women aged 16 and up.
