Maintenance Tips    
  • Keep fat tires properly inflated for best range, grip, and motor efficiency.
  • Charge the battery before it fully drains and store at 40–70% charge for long-term health.
  • Avoid water exposure to motor, display, and battery connections—never pressure wash.
  • Clean frame and drivetrain regularly, especially after dirt, sand, or rain rides.
  • Lubricate the chain and drivetrain often due to higher torque from electric assist.
  • Inspect and tighten bolts, rack mounts, and frame joints for safety and stability.
  • Check hydraulic/mechanical brakes frequently and replace pads when performance drops.
  • Monitor wheel trueness and spoke tension after rough terrain use.
  • Ensure all electrical connectors are secure and free of corrosion.
  • Schedule a professional e-bike tune-up every 6–12 months.
