A4 Fatboy Mountain eBike

For riders who want more than just the fattest tyres 

The A4 fat wheel ebike is a no-brainer pick for beginners and experienced pro cyclists alike. It is a comfortable all-year rounder capable of plowing through any terrain with ease. Built for serious off-road backpacking, the wider 26inch X 4inch KENDA tyres have a wider surface area for better traction. The A4 fat tyre ebike makes cycling through any terrain much easier.

The A4’s geometric design centers the rider between the wheel and lets them loft over obstacles across wild and diverse terrains. The A4 fatboy has a 6061 ALUMINIUM ALLOY TIG WELDED frame with rigid RST suspension fork. The fat wheel electric bike has SHIMANO ACERA 8 GEARS with derailleur protector drivetrain along with TEKTRO Aries front and rear disc brakes.  

The brakes are mounted on a TEKTRO brake lever with integrated bell featuring safe disconnection from motor while breaking. The 26inch X 4inch KENDA tyres and wheels offer more stability and rigidity when off-roading. The 1X8 speed drivetrain offers a fuzz-free gear change with derailleur protection.

A powerful, lightweight fattie 

The A4 fatbike has 26inch x 4inch KENDA fat tyres each with half size mud guards. It is built around a special 6061 ALUMINIUM ALLOY TIG WELDED frame with RST brand suspension fork. You get 8 speeds courtesy of PROWHEEL crankset and 8 Gears SHIMANO ACERA with stopping power delivered by TEKTRO Aries disc brakes with safe automatic motor disconnection. 

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.  

Explore nature on two wheels 

Try out an authentic off-roading experience on a fat wheel ebike with a tighter frame design for quick manoeuvrability around sharp corners and obstacles. Appreciate the additional stability of an RST band suspension fork and a PROWHEEL crankset with 5 pedal assist levels. 

Enjoy the convenience of a simple and trustworthy shifter to keep you on track all year long with 5 pedal assist levels. The 26inch fat tyres comfortably hold their own against soft sand, snow or mud. On top of their massive grip on wet surfaces, their thread design lets you get up some speed on hard surfaces including tarmac. 

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. 

A worthy battery for a worthy fatbike 

A high capacity and powerful fatboy bike motor aren’t something you cheap out on. That’s why we designed and built the A4 fatboy batteries with genuine and undeniably superior 36V 10.4 AH SAMSUNG battery.
