E-bike service parts checklist for Australian riders

These are the parts most riders replace regularly. Knowing the sizes and standards saves time and money.

• Batteries and chargers: 36 V, 48 V, or 52 V battery packs, matched chargers.
• Brakes: Pads, rotors (160, 180, 200 or 203 mm), hydraulic fluid or cables.
• Drivetrain: Chain, cassette/freewheel, chainring, jockey wheels, bottom bracket.
• Wheels and tyres: Tyres, tubes or tubeless valves, rim tape, spokes, nipples.
• Cockpit and bearings: Grips, bar tape, pedals, headset bearings, stems.
• Electronics and controls: Display, controller, wiring, sensors, lights, switches.
• Hardware and protection: Axle nuts, torque washers, brake adapters, guards.

How to choose compatible electric bike parts

Batteries and chargers: voltage, connectors, and safety

• Voltage: Match system voltage exactly.
  • 36 V battery charges to 42.0 V.
  • 48 V battery charges to 54.6 V.
  • 52 V battery charges to 58.8 V.
• Connectors: Check plug type and polarity. Common DC plugs include XT60, XT90, DC barrel, Anderson.
• BMS current: Ensure the battery’s BMS continuous current meets or exceeds your controller’s peak draw.
• Charger rating: 2 A to 4 A is common. Faster charging increases heat and wear.
• Compliance: Use RCM-compliant chargers for Australian 230 V mains.

Tip: For storage over 2 weeks, leave batteries at 40 to 60 percent and store near 15 to 25°C.

Warning: Never use a 52 V charger on a 48 V battery. Overvoltage can damage the BMS and cells.

Brakes: pads, rotors, and stopping power

• Pads:
  • Organic/resin for quiet braking and good initial bite.
  • Sintered/metallic for wet weather, cargo, and delivery loads.
  • Semi-metallic for balanced wear and noise.
• Rotors: Choose 180 to 203 mm for heavier riders or steep routes. Match mount type: 6-bolt or Center Lock.
• Fluid: Use the brake’s specified fluid only. Many use mineral oil, some use DOT 4 or DOT 5.1.

Specs and torques:

• Rotor bolts: typically 6 Nm.
• Center Lock lockring: 40 Nm.
• Caliper mounting bolts: 6 to 8 Nm.

Drivetrain: chains, cassettes, and e-bike strength

• Chain: Match your speed: 8, 9, 10, 11, or 12-speed. Look for e-bike rated chains with higher tensile strength.
• Cassette/freewheel: Match your hub type. Most modern hubs use cassettes. Older hub-motor wheels may use freewheels.
• Chainring: Narrow-wide rings help retention. Verify BCD or direct-mount standard.
• Bottom bracket: Common standards include BSA threaded, BB92, BB86. Check shell width and spindle type.

Tip: Mid-drive motors load chains heavily. Replace at 0.5 to 0.75 percent elongation to protect the cassette and chainring.

Wheels and tyres: ETRTO, load, and puncture protection

• Sizes: Use ETRTO numbers for accuracy. Examples: 700x40C is 40-622, 27.5x2.2 is 56-584, 20x4.0 fat is 100-406.
• Load rating: Choose e-bike approved tyres with reinforced casings for higher speeds and weight.
• Puncture control: Look for breaker layers or go tubeless with sealant.
• Pressures: Follow sidewall guidance. Typical ranges: 700x40C at 45 to 70 psi, 27.5x2.2 at 25 to 40 psi, 20x4.0 at 8 to 20 psi.

Warning: Do not exceed rim maximum pressure. Check rim internal width for tyre compatibility.

Cockpit and bearings: fit and control

• Handlebars: 31.8 mm or 35 mm clamp diameters are most common.
• Stems: Length and rise affect comfort and control. Torque stem faceplate bolts to 5 to 6 Nm.
• Headset: Verify bearing type, crown race diameter, and head tube standard.
• Pedals: Use grippy platforms or SPD for efficiency. Metal pins help in wet weather.

Electronics and controls: displays, sensors, and IP ratings

• Displays and controllers: Match communication protocol and connectors to your motor system.
• Cables and sensors: Look for waterproof quick connectors and strain relief.
• IP rating: IP65 or higher is preferred for regular rain riding.
• Lights: DC-powered lights should match system voltage or use a DC-DC converter.

Legal note (AU): EPACs limited to 250 W continuous with pedal assist up to 25 km/h comply nationally. Throttle-only bikes are generally limited to 200 W. Check your state rules for details.

Maintenance schedule for Australian e-bike riders

• Every week or 100 km: Tyre pressure, brake lever feel, quick visual bolt check, chain wipe and lube if wet.
• Every month or 300 to 500 km: Measure chain wear, true wheels lightly, inspect pads, check rotor thickness, check spoke tension.
• Every 6 months or 1,500 to 2,000 km: Replace chain if at limit, bleed brakes if spongy, replace gear cable and housing if sticky, refresh tubeless sealant.
• Annually: Inspect bearings, service bottom bracket and headset, check motor mounting bolts, run a full fastener torque audit.
• Battery care: Balance charge monthly. Avoid frequent 100 percent charges unless needed for range.

Installation torque and spec cheat sheet

Always confirm with your component manual. These are typical values:

• Rotor bolts: 6 Nm.
• Center Lock lockring: 40 Nm.
• Caliper mount bolts: 6 to 8 Nm.
• Stem faceplate: 5 to 6 Nm.
• Crank bolts (square taper): 35 to 45 Nm.
• Crank pinch bolts (two-bolt design): 12 to 14 Nm.
• Pedals: 35 to 40 Nm.
• Hub-motor axle nuts: 30 to 40 Nm, with torque washers properly seated.

Tip: Use a quality torque wrench to protect carbon and alloy parts, and to prevent creaks.

E-bike service parts for delivery riders

• Brake setup: Sintered pads with 180 to 203 mm rotors for long descents and heavy loads.
• Tyres: Puncture-protected tyres or tubeless with sealant. Add reflective sidewalls for night work.
• Drivetrain: Inspect chain weekly. Carry a quick link and mini multi-tool.
• Electrics: Weatherproof lights, IP65 cabling, spare charger at home and work.
• Spare kit: Tube, levers, pump or CO2, pad set, link, rotor bolt set, zip ties, tape.
• Charging habits: Partial top-ups reduce heat and extend battery life during shift breaks.

FAQs

How often should I service my e-bike?
Light commuters can service monthly or every 300 to 500 km. Delivery riders should check brakes, chain, and tyres weekly. Do a full inspection at least twice a year.

Which brake pads are best for wet weather in Australia?
Sintered pads handle heat and water better, with longer life under heavy loads. They can be noisier than resin pads but offer consistent performance in rain.

Can I use a 52 V charger on a 48 V e-bike battery?
No. A 52 V charger will overcharge a 48 V battery. Always match charger output voltage to the battery’s full-charge voltage.
