5. Operating Instructions

5.1 Riding Modes and Pedal Assist Levels

The DUOTTS S26 offers versatile riding experiences with three distinct modes and five pedal assist levels:

• Pure Electric Mode: Engage the twist throttle for motor-only propulsion without pedaling.
• Assisted Bicycle Mode (PAS): The motor provides assistance based on your pedaling effort. There are 5 levels of pedal assist, allowing you to control the amount of motor support.
• Normal Bike Mode: Ride the bike like a traditional bicycle, using only pedal power with no motor assistance.

5.2 Dual Motor Operation

The S26 features dual 750W motors (3000W peak combined) for powerful performance. You can switch between single and dual motor modes. Dual motor mode provides maximum power and torque, ideal for steep inclines or off-road conditions, but will consume battery faster.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your DUOTTS S26 Electric Bike.

• Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
• Tires: Maintain proper tire pressure (refer to tire sidewall for recommended PSI). Inspect tires for wear and damage. The 26" x 4.0" fat tires provide excellent grip and stability.
• Brakes: Regularly check the dual hydraulic brakes for proper function and wear on brake pads. Adjust as needed.
• Chain: Keep the chain clean and lubricated for smooth gear changes and to prevent rust.
• Suspension: Inspect the front suspension fork and rear shock for proper function. The front fork allows adjustment for softness or firmness.
• Battery Care: Store the battery in a cool, dry place. If storing for extended periods, charge it to about 50-70% every few months.
