Why KEPLER DUAL BATTERY rides different

Built for real-world riding

Kepler Dual Battery is engineered for real-world e-bike riding, not just specs on paper. These videos show how its dual-battery range, torque and cadence pedal assist, and ride control perform in everyday urban conditions, longer commutes, and mixed terrain.

Sensor System

Torque and Cadence Assist

Two assist modes in one bike. Torque delivers power that responds instantly to how hard you pedal for a natural, controlled ride, while cadence provides smooth, steady assist for easy cruising and longer distances with less effort.

Battery Safety

Thermal-Protected Battery

Our advanced battery uses high-grade lithium cells with thermal-resistant tech, encapsulating each cell in heat-absorbing resin for greater safety, efficiency, and lifespan.

Durability & Control

Protected Dual-Crown Front Fork

A reinforced dual-crown front suspension fork with 80mm of travel and extended rubber protection keeps the front end stable, controlled, and well-protected over daily riding conditions.

Comfort & Control

Suspension Seat Post

Built-in suspension absorbs bumps and road chatter, reducing fatigue and improving comfort on longer rides, without changing your riding position or control.

Which Sensor is Right for You?

Torque reacts to effort. Cadence reacts to pedal rotation. Pick the ride feel you want.

Dual-Crown Front Suspension

Dual-Crown Front Suspension

Heavy-duty dual-crown front fork designed for stability and control.

With 80mm of suspension travel and a reinforced two-crown design, it keeps the front end steady under braking and smooth over rough pavement. A hydraulic lockout lets you firm it up when you want a more rigid, efficient ride.

Two Pedal Assist Feel Options

You can choose how the motor reacts when you pedal. Torque mode feels more responsive and natural. Cadence mode provides consistent power with less effort. Switch anytime to match your comfort and riding style.

Smoother Ride Seatpost

Smoother Ride Seatpost
