Rolling over anything and going everywhere 

The A4 sports a powerful BRUSHLESS HUB 36V 250W XOFO FAT high torque motor powered by a 36V 10.4AH SAMSUNG battery. The electric motor takes the grueling effort out of powering the ebike. The motor-battery combo is capable of reaching a maximum speed of 15.5MPH and delivering up to 60 KM of ride range depending on rider, road, climb degree and pas selected. When dusk comes, the SIBANG HEAD LIGHT & TAILLIGHT keep the fun going.

A straightforward ebike 

The A4 fatboy ebike is more than pleasant to look at. The chunky knobs provide predictable traction in soft condition while the KD21C LCD control module with 5 PAS LEVELS provides a miniaturised infotainment console with essential dials for battery indicator, speed meter, lights on/off motor control. The A4 fatboy is intentionally designed with ZOOM handlebar and stem to give riders more stability in loose conditions and lighter steering even at higher speeds. With 3.5hrs charge time and nearly 60km range, the bikes geometry and power prove that more is always better. 

The 26inch x 4inch KENDA wheels are fun and weight conscious; at only 28kg, the A4 has a carrying capacity of 120kg. The RST band suspension absorbs shock on harder surfaces and bumps making your ride smoother and predictable.
