4. Operating Instructions

Familiarize yourself with the operating functions of your DEEPOWER S20 Electric Bike for a safe and enjoyable ride.

4.1 Powering On/Off

• To Power On: Press and hold the power button on the LCD display for a few seconds until the screen illuminates.
• To Power Off: Press and hold the power button on the LCD display again until the screen turns off.

4.2 Riding Modes

The S20 offers three riding modes:

• Manual Mode (Pedal Only): Ride the bike like a traditional bicycle without motor assistance.
• Pedal Assist Mode (PAS): The motor provides assistance as you pedal. You can adjust the level of assistance (typically 1-5) using the controls on the display. Higher levels provide more power.
• Full Electric Mode (Throttle): Use the twist throttle on the handlebar to engage the motor without pedaling. This mode provides full motor power up to the maximum speed.

4.3 Gear Shifting

The S20 is equipped with a 7-speed gear system. Use the shifter on the right handlebar to change gears. Shift to a lower gear for easier pedaling on inclines and a higher gear for faster speeds on flat terrain.

4.4 LCD Display

The advanced LCD display provides real-time information about your ride.

• Speed: Current riding speed.
• Distance: Trip distance and total odometer.
• Battery Level: Indicates remaining battery charge.
• PAS Level: Shows the current pedal assist level.
• Error Codes: Displays diagnostic codes if an issue occurs.

4.5 Battery Management

The 48V 25Ah removable lithium battery provides extended range. For optimal performance and longevity:

• Charge the battery fully before the first use and after each ride.
• Avoid completely draining the battery.
• Store the battery in a cool, dry place when not in use, and charge it periodically if stored for long periods.
• The battery is removable with a key lock for security and convenient charging.

4.6 Braking System

The DEEPOWER S20 is equipped with mechanical disc brakes on both the front and rear wheels for reliable stopping power.

• Apply both brake levers simultaneously for balanced and effective braking.
• Avoid sudden, hard braking, especially at high speeds or on loose surfaces, to prevent skidding.
• Regularly check brake pads for wear and replace them when necessary.

4.7 Lighting System

The bike features a high-brightness headlight, taillight, and signal lights for improved visibility and safety.

• Turn on the headlight and taillight when riding in low-light conditions or at night.
• Use the signal lights to indicate turns to other road users.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your DEEPOWER S20 Electric Bike.

5.1 Routine Checks

• Tires: Check tire pressure weekly. Recommended pressure is typically listed on the tire sidewall. Inspect for punctures or excessive wear.
• Brakes: Regularly check brake lever feel and pad wear. Adjust brake cables as needed to maintain proper tension.
• Chain: Keep the chain clean and lubricated. A dry or dirty chain can lead to poor shifting and premature wear.
• Fasteners: Periodically check all bolts and nuts (handlebars, seat post, wheels, crank arms) for tightness.
• Suspension: Inspect suspension components for any leaks or damage. Keep stanchions clean.

5.2 Cleaning

Clean your bike regularly with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components, bearings, or seals.

5.3 Battery Care

• Do not expose the battery to extreme temperatures.
• If the bike is not used for an extended period, charge the battery to 50-70% and store it in a cool, dry place. Recharge every 1-2 months.
• Only use the charger provided by DEEPOWER.
