Electric motocross APOLLO RFN SX-E15 blue/red

Discover the RFN SX-E15, a full-size electric motocross bike designed for riders aged 15 and over and adults approximately 1.65–1.90 m tall. Positioned in the equivalent 85 cc category, it delivers the size, sensations and commitment of an 85 cc racing bike – without the mechanical constraints of a combustion engine.

Up to 15 kW of power, a top speed of 90 km/h and a racing architecture designed to fully exploit electric torque.

⚙ 15 kW and integrated gearbox: total torque control

The RFN SX-E15 develops a nominal power of 8 kW through its high-performance electric motor, powered by a removable Samsung 74 V 40 Ah lithium battery. This configuration delivers strong, progressive acceleration, perfectly usable when exiting corners and during acceleration phases.

Its distinctive feature in the range is the integration of a genuine gearbox. This system makes better use of the available torque, optimises acceleration and precisely adapts motor response to the terrain and riding style.

The result:

• Stronger acceleration
• Better low-speed torque management
• More effective acceleration out of corners
• Riding sensations close to an 85 cc racing bike

Range can reach up to 2 hours depending on the mode used and riding intensity. Thanks to fast charging, a full charge takes just 3 hours.

The electronic management system offers 10 fully adjustable riding modes through the RFN mobile app. This interface allows precise adjustment of several essential riding parameters, including throttle sensitivity and regenerative braking use.

The bike’s behaviour can therefore be adapted to the rider’s level, the terrain or riding conditions, providing an evolutive and fully customisable machine.

⚙ Aluminium frame and swingarm: full-size stability

The RFN SX-E15 is built around an aluminium frame and aluminium swingarm, ensuring structural rigidity, precision and controlled lightness.

Fitted with 16"–19" wheels, it adopts a competition-style full-size format offering:

• Stability at high speed
• Improved obstacle-clearing ability
• Precision when cornering
• Confidence on landing

The 880 mm seat height naturally places the rider in an aggressive stance, suited to committed riding on tracks or technical terrain.

⚙ Fully adjustable racing suspension

The fork and rear shock are fully adjustable for compression, rebound and preload.

This level of adjustment allows precise tuning:

• According to rider weight
• According to the terrain
• According to riding intensity
• According to the type of use

Landing progression, acceleration stability and precision under hard braking are optimised for intensive use.

⚙ High-performance braking

Disc brakes provide powerful, consistent and progressive braking, essential at speeds of up to 90 km/h. Control remains stable even during prolonged use.

The optimised transmission and advanced electronic management provide immediate and controlled traction.

⚙ Performance without the constraints

The RFN SX-E15 lets you ride more often, with less maintenance and without the regular mechanical adjustments required by a combustion engine. No carburettor to adjust, no fuel mixture to prepare and no excessive vibrations.

The goal is simple: maximise riding time and rider progression.

Before first use, check all fasteners and fully charge the battery. Set the appropriate riding mode via the RFN app. Recharge after every session and avoid complete discharge to preserve battery life. Store the vehicle in a dry, temperate place.

Wearing a full-face helmet and suitable protective equipment is essential. Vehicle delivered partially assembled.
