Euybike S4 Moped Electric Bike 1000W 28MPH 100-Mile Range 48V 25Ah 20"x4" Fat Tire 400lb Capacity

The Euybike S4 is a moped-style fat tire electric bike that blends the speed and presence of a moped with the eco-friendly efficiency of an e-bike. Powered by a 1000W rear hub motor delivering 96 N.m of maximum torque, it reaches a top speed of 28 MPH with confident, smooth acceleration. The massive 48V 25Ah lithium-ion battery — 1200Wh total capacity — provides an impressive 100-mile range per charge, making the S4 one of the longest-range fat tire e-bikes available. A 48V/25A controller and fast charger compatible with 100V–220V input keep downtime to a minimum.

The signature double shock frame design sets the S4 apart from standard e-bikes, delivering a genuinely moped-style ride comfort that absorbs road vibration and rough terrain effectively. A dual crown front suspension fork with lockout and adjustment further refines the ride quality, while the soft PU shock-absorbing saddle ensures all-day comfort on extended rides. The 20" x 4.0" fat tires on spoke wheels provide superior traction and stability across pavement, gravel, sand, and uneven terrain alike.

Five intelligent pedal-assist levels plus a twist throttle give complete riding flexibility — from full electric cruising to active pedaling with motor support. Shimano 7-speed gearing with a KMC chain delivers reliable shifting performance across varying terrain gradients, while Logan 180mm hydraulic disc brakes with motor cutoff grip levers provide powerful, precise stopping power in all conditions. An adjustable handlebar height accommodates riders from 5'7" to 6'5", and the maximum load capacity of 400 lbs makes the S4 one of the most capable high-capacity e-bikes in its segment.

A 48V LED front light ensures visibility for night riding, plastic fenders keep clothes protected from road spray, and pedals with reflectors add an extra layer of safety. The LCD provides clear real-time readouts of speed, battery level, and assist mode at a glance.
