Gear System (21-Speed)
The 21-speed gear system allows you to adapt to different terrains and riding conditions.
- Use the left shifter for the front chainrings (3 speeds) and the right shifter for the rear cassette (7 speeds).
- Shift to lower gears (larger rear cogs, smaller front chainrings) for climbing hills.
- Shift to higher gears (smaller rear cogs, larger front chainrings) for flat roads and higher speeds.
- Always pedal lightly when shifting gears to ensure smooth transitions and prevent damage.
Braking System
The dual mechanical disc brakes provide reliable stopping power.
- Apply both front and rear brakes simultaneously for effective and stable braking.
- Avoid sudden, hard braking, especially with the front brake, to prevent skidding.
- Regularly check brake pads for wear and ensure cables are properly tensioned.
Maintenance
Regular maintenance ensures the longevity and safe operation of your electric bike.
- Cleaning: Clean the bike regularly with a damp cloth. Avoid high-pressure washing directly on electrical components.
- Lubrication: Lubricate the chain and other moving parts periodically to reduce wear and ensure smooth operation.
- Tire Pressure: Check tire pressure before each ride. Maintain recommended PSI for optimal performance and safety.
- Brake Inspection: Inspect brake pads for wear and replace them when necessary. Ensure brake levers and cables are functioning correctly.
- Battery Care: Store the battery in a cool, dry place. If storing for extended periods, charge it to 50-70% every few months.
- Fastener Check: Periodically check all bolts and fasteners for tightness, especially on critical components like handlebars, wheels, and seat post.
