5. Setup

5.1 Unpacking and Assembly

Your ENGWE E26ST Electric Bicycle comes partially assembled. Carefully remove all components from the packaging. It is recommended to have a second person assist with assembly.

1. Handlebar Installation: Attach the handlebar to the stem, ensuring it is centered and the brake levers and shifters are in a comfortable position. Tighten all bolts securely.
2. Front Wheel Installation: Install the front wheel, ensuring the disc brake rotor is correctly seated within the caliper. Secure the quick-release skewer or axle nuts.
3. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal threads counter-clockwise, and the right pedal threads clockwise. Apply a small amount of grease to the threads and tighten them firmly.
4. Seat Post Installation: Insert the seat post into the frame, adjusting the height for a comfortable riding position. Ensure the minimum insertion mark is not visible. Secure with the quick-release clamp.
5. Fender and Rear Rack Installation: Attach the front and rear fenders, and the rear rack, using the provided hardware. Ensure they are stable and do not interfere with wheel rotation.
6. Initial Inspection: Double-check all bolts, nuts, and quick releases to ensure they are tight and secure. Inspect brake cables, gear cables, and electrical connections.

5.2 Battery Charging

Before your first ride, fully charge the battery.

1. Locate the charging port on the battery (usually on the frame).
2. Connect the charger to the charging port, then plug the charger into a standard wall outlet.
3. The charger indicator light will typically show red during charging and turn green when fully charged.
4. Charging time is approximately 5.5-6 hours. Do not overcharge the battery.
5. Always charge the battery in a well-ventilated area, away from flammable materials.

6. Operating Instructions

6.1 Powering On/Off

1. To power on the e-bike, press and hold the power button on the LCD display for a few seconds.
2. To power off, press and hold the power button again until the display turns off.

6.2 Riding Modes

The ENGWE E26ST offers multiple riding modes:

• Pedal Assist Mode (PAS): The motor provides assistance as you pedal. Use the '+' and '-' buttons on the display to adjust the assist level (0-5 gears). Level 0 provides no assistance, while Level 5 provides maximum assistance.
• Throttle Mode: Engage the throttle (usually on the right handlebar) to propel the bike without pedaling. This mode is typically available in higher assist levels.
• Manual Mode: Ride the bike like a traditional bicycle with no motor assistance.

6.3 Gear Shifting

Your e-bike is equipped with a 7-speed SHIMANO derailleur system.

1. Use the shifter on the right handlebar to change gears.
2. Shift to lower gears for easier pedaling on inclines and higher gears for faster speeds on flat terrain.
3. Always ease off the pedals slightly when shifting gears to ensure smooth transitions and prevent damage to the drivetrain.

6.4 Braking

The e-bike features hydraulic disc brakes for powerful and responsive stopping.

1. Apply both brake levers simultaneously for balanced and effective braking.
2. Practice braking in a safe area to get a feel for the stopping power.
3. Avoid sudden, hard braking, especially the front brake, as this can lead to loss of control.

7. Maintenance

7.1 General Care

• Cleaning: Regularly clean your e-bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components.
• Lubrication: Keep the chain, gears, and other moving parts lubricated with appropriate bicycle lubricant.
• Tire Pressure: Check tire pressure before each ride. Maintain the recommended pressure (usually indicated on the tire sidewall) for optimal performance and safety.
• Bolt Checks: Periodically check and tighten all bolts and fasteners, especially on critical components like the handlebars, seat post, wheels, and brakes.

7.2 Battery Care

• Charging: Charge the battery regularly, even if not used frequently, to maintain its health. Avoid completely draining the battery.
• Storage: If storing the e-bike for an extended period, charge the battery to 50-70% and store it in a cool, dry place. Recharge every 1-2 months.
• Temperature: Avoid exposing the battery to extreme temperatures (hot or cold) as this can affect its lifespan and performance.

7.3 Brake Maintenance

• Brake Pad Wear: Regularly inspect brake pads for wear. Replace them when they are worn down to the minimum thickness.
• Brake Fluid: Hydraulic brakes require periodic fluid checks and bleeding. If you notice a spongy feel in the brake levers, consult a professional bicycle mechanic.

8. Troubleshooting

This section addresses common issues you might encounter with your ENGWE E26ST Electric Bicycle.

8.1 No Power to Display/Motor

• Check Battery: Ensure the battery is fully charged and properly seated in its compartment.
• Check Connections: Verify all electrical connections, especially to the motor and display, are secure and free from damage.
• Power Button: Ensure the power button on the display is pressed and held correctly to turn on the system.

8.2 Motor Not Assisting

• Pedal Assist Level: Check that the pedal assist level on the LCD display is set to a level greater than 0.
• Brake Levers: Ensure brake levers are not partially engaged, as most e-bikes have a safety cut-off that disengages the motor when brakes are applied.
• Sensor Check: Inspect the pedal assist sensor (PAS) for any obstructions or damage.

8.3 Poor Braking Performance

• Brake Pads: Check brake pads for wear and replace if necessary.
• Brake Levers: Ensure brake levers are not loose and have proper tension. For hydraulic brakes, a spongy feel may indicate air in the system or low fluid, requiring professional service.
• Disc Rotors: Check rotors for bends or damage. Keep them clean and free of oil or grease.

8.4 Gears Not Shifting Smoothly

• Cable Tension: Check the tension of the gear cables. Adjust if too loose or too tight.
• Derailleur Alignment: Ensure the derailleur is properly aligned. If bent or misaligned, it may require adjustment or replacement by a professional.
• Chain Condition: A dirty or worn chain can affect shifting. Clean and lubricate the chain regularly.

9. User Tips

• Enjoy Daily Rides: The ENGWE E26ST is praised for providing an excellent riding experience, suitable for daily commutes and workouts. Make it a part of your routine!
• Regional Power Variants: Be aware of regional power variants: EU models typically have 250W motors, while US models feature 750W motors. Confirm the appropriate power for your region to ensure compliance with local regulations.
• Consider Product Weight: The product weight is 34.5 kg. Keep this in mind for transport, lifting, and storage.
• Regular Cleaning: Keep your e-bike clean, especially after riding in muddy or wet conditions, to prolong the life of components.
• Battery Management: For optimal battery longevity, avoid completely draining the battery and store it partially charged if not used for extended periods.
