10. User Tips

Enhance your riding experience with these practical tips:

• Pre-Ride Check: Always do a quick check of tire pressure, brake function, and battery level before each ride.
• Battery Management: For optimal battery life, avoid fully discharging the battery frequently. Try to keep it between 20% and 80% charge.
• Gear Shifting: Shift gears smoothly and avoid shifting under heavy load, especially when using pedal-assist, to protect the drivetrain.
• Terrain Awareness: While the fat tires are all-terrain, be mindful of extremely rough or slippery surfaces. The front fork suspension helps absorb shocks, but careful riding is always recommended.
• Security: Always lock your ebike and remove the battery when leaving it unattended to prevent theft.
• Local Regulations: Stay informed about local ebike laws, including speed limits and helmet requirements.
