E-Bike Maintenance Schedule & Checklist

An e-bike needs more maintenance than a regular bike — the motor, battery, and electrical components add complexity. But most maintenance is simple, and a consistent schedule prevents expensive failures.

Weekly Checks (5 Minutes)

Tyre Pressure

Check and inflate both tyres to the recommended PSI (printed on the tyre sidewall). Tyres lose 1–3 PSI per week naturally.

Why it matters: under-inflated tyres increase rolling resistance (reducing range by 10–20 %), increase puncture risk, and wear faster.

Brake Test

Squeeze each brake lever separately while walking the bike forward. Each brake should stop the bike firmly within the lever travel — the lever should not touch the handlebar grip.

Lights and Reflectors

Check that all lights work (front, rear, any integrated lights). Check that reflectors are present and clean.

Quick Visual Check

Look at the bike for anything obviously wrong: loose bolts, damaged cables, worn tyres, anything rubbing against a tyre or wheel.

Monthly Checks (15 Minutes)

Chain Condition

Clean: wipe the chain with a rag, apply chain lube to each roller while pedalling backward, wipe off excess.

Check wear: use a chain wear checker tool ($10–$15). E-bike chains wear faster — expect replacement every 2,000–3,000 km (mid-drive) or 3,000–5,000 km (hub motor).

Brake Pads

Check brake pad thickness through the caliper. Replace when the pad material is thinner than 1 mm.

Bolt Check

Check these bolts are tight:

• Stem bolts: 5–6 Nm
• Handlebar bolts: 4–5 Nm
• Seat clamp: 5–6 Nm
• Axle nuts/thru-axle: 12–15 Nm (front), 35–40 Nm (rear)
• Crank arm bolts: 35–40 Nm (mid-drive)
• Disc brake rotor bolts: 6–8 Nm

Electrical Connectors

Check all visible connectors are fully plugged in, not corroded, not frayed, and rubber seals are intact.

Battery Contacts

Wipe the battery contacts with a clean, dry cloth.

Every 3 Months (30 Minutes)

Deep Chain Clean

Remove the chain and soak in degreaser, or use a chain cleaning device.

Brake Rotor Clean

Wipe disc brake rotors with isopropyl alcohol and a clean cloth. Never use WD-40 or oil-based cleaners on rotors or pads.

Spoke Tension

Squeeze spokes in pairs. If any are noticeably loose or tight, the wheel needs truing (bike shop job).

Derailleur Adjustment

Shift through all gears — every shift should be smooth. Check cable tension and derailleur hanger alignment.

Suspension (If Fitted)

Wipe fork stanchions, check for oil leaks, bounce the fork for smooth operation.

Every 6 Months / Annual Service

Professional Service

Book an annual service at a qualified e-bike mechanic:

• Full drivetrain inspection
• Brake inspection and adjustment (bleed hydraulic brakes if needed)
• Wheel truing and spoke tensioning
• Bearing check (headset, bottom bracket, wheel hubs)
• Motor inspection
• Battery health check
• Electrical system check
• Firmware update (if available)
• Safety check (frame, fork, bolts)

Cost: $100–$250 for a standard service. Budget $200–$400 if major work is needed.

Battery Maintenance

Storage (if not riding for 2+ weeks):

• Charge to 40–60 % before storage
• Store indoors at room temperature (15–25 °C)
• Never store fully charged or fully discharged
• Check charge level monthly

Charging habits:

• Let the battery cool before charging after a hot ride
• Do not leave on the charger indefinitely after 100 %
• Charge when the battery reaches 10–20 %

Replacement Intervals

Component	Typical life (e-bike)	Cost
Chain	2,000–4,000 km	$20–$50
Brake pads (pair)	3,000–5,000 km	$15–$40
Cassette	6,000–10,000 km	$30–$80
Tyres	4,000–8,000 km	$40–$100 each
Chainring	6,000–12,000 km	$30–$60
Brake rotors	10,000–20,000 km	$20–$50 each
Cables and housing	Annually	$15–$40
Battery	500–1,000 cycles (3–5 years)	$400–$1,200
Hub motor bearings	5,000–15,000 km	$50–$100 (labour)
Mid-drive motor service	10,000–15,000 km	$100–$300

Tools You Need at Home

Basic toolkit ($50–$100):

• Allen key set (2, 2.5, 3, 4, 5, 6, 8 mm)
• Tyre levers (set of 3)
• Floor pump with pressure gauge
• Chain lube and degreaser
• Clean rags
• Spare inner tube and patch kit
• Multi-tool

Worth adding ($50–$150):

• Chain wear checker ($10)
• Torque wrench ($40–$100)
• Isopropyl alcohol ($10)
• Chain quick link pliers ($15)

Bottom Line

E-bike maintenance is not complicated — it just needs to be consistent. A 5-minute weekly check (tyres, brakes, lights) and a 15-minute monthly check (chain, pads, bolts, connectors) prevent 90 % of failures. Book an annual professional service for bearings, motor internals, and hydraulic brakes. Budget $200–$500 per year for maintenance and consumables.
