How to Maintain an Electric Bike?

The maintenance of an electric bike directly affects its range, performance, and service life. Below is a detailed guide on core component upkeep, daily usage tips, and seasonal maintenance, tailored to practical scenarios:

Battery Care: Core for Extending Range

1. Optimizing Charging Habits

Charging Timing

  • Avoid deep discharge (charge when battery level drops below 20%). It’s recommended to charge at 30%-50% remaining and stop at 80%-90% (overcharging accelerates degradation).
  • If riding 10 miles (approx. 16 km) daily, charge every 2-3 days instead of daily.

Temperature Control

  • Charge at 15-25°C (charge in a garage during winter; avoid direct sunlight in summer).
  • In extreme cold (e.g., Minnesota winters), bring the battery indoors to warm up before charging to prevent cell damage from low temperatures.

Long-Term Storage

  • If unused for over a month, maintain a 40%-60% charge (avoid full or empty storage) and charge once a month.

2. Charging Equipment & Safety

  • Use the original charger to prevent overcharging or short circuits from third-party chargers.
  • Ensure the outlet is properly grounded when charging, and suspend charging during thunderstorms.

Motor & Controller: Powertrain Maintenance

1. Motor Cleaning & Protection

Daily Cleaning

  • Wipe dust and dirt from the motor casing with a dry cloth; avoid direct water rinsing (especially for hub motors, as water ingress may damage coils).
  • After riding through muddy roads, promptly clean debris around the motor with a soft brush.

Abnormal Noise Troubleshooting

  • Unusual motor noise (e.g., harsh friction) may indicate bearing wear or internal debris. Contact a dealer for inspection (e.g., REVR’s offline store: Riding 5).

2. Controller Waterproofing & Moisture Protection

  • After riding in the rain, check for water ingress at interfaces and dry water stains with a tissue.

Body Component Maintenance: From Brakes to Tires

1. Brake System Inspection

Disc Brake Maintenance

  • Check brake pad wear weekly (replace if the thickness is below 2mm). Lightly sand the disc brake rotor if it makes noise.
  • Replace brake fluid for hydraulic disc brakes every 1-2 years.

Braking Distance Test

  • On dry roads, braking at 15mph (approx. 24km/h) should stop within ≤2 meters; increase to ≥3 meters in rain, and adjust brake sensitivity if needed.

2. Tire Management

Tire Tread Inspection

Check tires for cracks or foreign objects (e.g., glass shards) before each ride. Replace tires when the tread depth is below 1.6mm.

3. Chain & Drivetrain

Chain Tension

  • Press the middle of the chain with a finger; it should sag 10-15mm. Adjust via the rear derailleur tension screw or chain tool if too loose (causing skipping) or too tight (damaging the freewheel).

Electronic System & Accessory Maintenance

1. Display & Sensors

  • Wipe the display with a slightly damp soft cloth; avoid alcohol or cleaners to prevent coating damage.
  • If speed or cadence sensors lose signal (e.g., inconsistent assist), adjust their position with a wrench to within 5mm of the freewheel/chainring.

2. Lighting & Circuit Check

  • Test front/rear lights and brake lights monthly. For unlit LEDs, replace batteries first or check connections (oxidation in waterproof plugs).
  • If the circuit shorts (e.g., no response when the key is turned), replace the fuse (typically in the battery compartment) with the same specification.

Seasonal Maintenance

1. Summer (High Temperature & Rain)

  • In high-temperature areas like California: Avoid parking the bike in direct sunlight after riding; move it to shade if the battery compartment exceeds 40°C.
  • In rainy Florida: Rinse mud from the frame bottom with water after rain, and lubricate the chain to prevent rust.

2. Winter (Low Temperature & Snow)

  • In snowy areas like Boston: Rinse snow from tires and brake rotors with warm water after riding to prevent salt corrosion (use a neutral cleaner).
  • At temperatures below 0°C, the range may decrease by 30%. Wrap the battery in an insulated cover during rides.

3. Spring & Autumn (Transition Period)

  • In windy Colorado springs: Check handlebar and seat bolts for looseness (wind resistance may displace components), and tighten with an Allen wrench to specified torque (e.g., 10Nm for handlebar bolts).
  • In autumn leafy areas: Clean leaves from the freewheel and chain to avoid jamming (Can use a high-pressure water gun, low-pressure washing.).

Professional Maintenance Tips: When to Seek Repairs?

Annual Comprehensive Inspection

  • Even without obvious issues, visit a brand dealer (e.g., REVR’s Riding 5) annually for:
  • Battery health testing (internal resistance test; repair or replace if capacity drops below 80%);
  • Motor bearing lubrication;
  • Brake system bleeding and fluid replacement (mandatory for hydraulic disc brakes).

Emergency Repair Scenarios

  • Sudden motor power loss or abnormal heating (over 60°C);
  • Brake failure or sudden loss of stopping power;
  • Bulging or leaking battery casing (stop use immediately and keep away from fire).
