• Brake System Maintenance

  Effective braking is vital for safety, especially at higher speeds enabled by a 72V system. Inspect brake pads weekly for wear; replace them if thickness drops below 2mm. For hydraulic brakes, flush the brake fluid every 6–12 months to remove moisture and maintain optimal pressure response. Use DOT 4 or mineral oil (depending on system type) as specified by the manufacturer.

  Mechanical brakes require more frequent attention: lubricate cables every 3–4 weeks and adjust tension to ensure firm lever feel without binding. Check rotors for warping or scoring—replace if uneven or cracked.

• Wheel and Tire Care

  Maintain tire pressure according to the manufacturer’s recommendation (typically 12–18 psi for off-road use). Under-inflation increases rolling resistance and risk of pinch flats, while over-inflation reduces traction and comfort. Inspect tires for cuts, embedded debris, or tread wear—replace immediately if compromised.

  Spin each wheel to check for wobbling, which indicates rim misalignment (out of true). Use a truing stand or consult a technician to correct bends. Ensure quick-release skewers or axle nuts are securely tightened before every ride.

• Electric Motor Maintenance

  The motor is sealed and generally maintenance-free, but external cleaning is essential. Use a soft brush and damp cloth to remove mud, dust, and debris from ventilation slots and housing. Never use high-pressure water, as it may breach seals and damage internal windings or bearings.

  Listen for unusual noises (grinding, clicking) during operation, which could indicate bearing wear or rotor misalignment. If performance drops or the motor overheats frequently, have it inspected by a qualified technician. Avoid riding through deep water unless the motor is IP67-rated or higher.

• Chain and Gearing System

  Keep the chain clean and properly lubricated using a dirt-resistant, wet-lube chain oil. Clean the chain with a brush and biodegradable degreaser every 5–10 rides, then re-lubricate. Check chain tension weekly—there should be about 1 inch of vertical play. Adjust via the rear axle or tensioner as needed.

  Inspect the sprockets and cassette for hooked teeth or excessive wear. Replace the chain and drivetrain components as a set when wear is evident to prevent premature damage. A worn chain can reduce efficiency and increase strain on the motor.

• Suspension System Maintenance

  Front forks and rear shocks absorb impact and improve control. Check for oil leaks around stanchions and shock bodies—leaking seals reduce damping effectiveness. Wipe down fork legs after each ride and inspect dust boots for tears that allow grit inside.

  Lubricate suspension linkages and pivot points every 20 hours of riding. For air-sprung suspension, check pressure monthly using a shock pump. Hydraulic systems may require professional servicing (rebounding, compression adjustment) annually or after heavy use.

• Regular Cleaning Routine

  After off-road use, clean the bike thoroughly to prevent buildup of mud, sand, and corrosive elements. Use a garden hose (low pressure) and mild detergent. Avoid spraying directly at electrical connectors, the motor, controller, or battery compartment.

  Dry all components with a microfiber towel, especially around brakes, rims, and joints. Apply a light protectant to metal surfaces to prevent rust. Never store the bike wet or in humid environments.

Pro Tip: Create a maintenance log to track service dates, component replacements, and performance observations. This helps identify patterns, anticipate part failures, and maintain warranty eligibility. Consider installing a digital voltage monitor to keep real-time track of battery health during rides.
