Combining cutting-edge technology with race-ready features, the SX-E5 offers a ride that rivals and in many ways outclasses traditional 50cc petrol bikes.

Electric Muscle with Unmatched Torque

At the heart of the SX-E5 lies a 5kW Peak Output Motor, delivering an impressive 7 horsepower and a ground-gripping 145Nm of torque. With a top speed of 60 km/h, this electric warrior doesn’t just keep up with combustion-powered 50cc bikes it blows them away in acceleration and responsiveness, all without the noise, heat, or fumes.

High-Capacity Swappable Battery

Powered by a 48V 25Ah Lithium-Ion battery (1,200Wh), the SX-E5 offers a range of up to 40km at a steady cruising speed of 35 km/h. When the adventure’s not over, a 2-hour fast charging system and swappable battery design mean you can be back on the trails in no time.

Built for Real Off-Road Riding

Equipped with a 12” front and 10” rear knobby tire setup, the SX-E5 is ready to tackle everything from backyard dirt tracks to proper off-road trails. With 205mm of front suspension travel and 180mm rear travel, it soaks up bumps with ease and delivers a smooth, controlled ride ideal for developing skills in comfort and confidence.

Lightweight and Rider-Friendly

Weighing just 47kg, the SX-E5 is much lighter than petrol equivalents, making it easier for younger riders to handle, balance, and pick up if dropped. The adjustable seat height (615–665mm) ensures a perfect fit for a growing rider.

Clean, Quiet, and Low-Maintenance

Unlike petrol bikes, there’s no engine noise, no hot exhaust pipe, no fuel mixing, and no oil changes. That means less time maintaining, more time riding, and a safer, cleaner experience for both kids and parents.

Safety-First Features

Hydraulic Disc Brakes (Front & Rear) for reliable stopping power, Three-Speed Ride Modes for rider progression and parent-controlled limits, Steel Frame Construction for off-road durability, Electronic Controller with Advanced Motor Algorithms for smooth throttle control.
