- Dielectric grease & contact brush for battery terminals
Maintenance Schedule (Pre-ride → Annual)
| Cadence | Tasks | Why it matters |
|---|---|---|
| Before every ride | Check tire pressure; quick brake squeeze; battery level; look for loose parts/cables. | Prevents flats, improves range, catches issues early. |
| After wet/muddy rides | Rinse gently; dry; relube chain; wipe rotors dry. | Protects bearings & electronics; restores efficiency. |
| Weekly | Drivetrain wipe & lube; bolt spot-check; visual cable/connector check. | Reduces wear and intermittent cut-outs. |
| Monthly | Deep clean; inspect pads/rotors; tread & spoke check; firmware update check. | Smoother, quieter bike; safer stopping; latest fixes. |
| Seasonally | Battery health review; dielectric grease on terminals; replace chain if stretched; tire refresh. | Maintains range & reliability; avoids cascading wear. |
| Annually / ~2,000 km | Pro service (mechanical + electronic diagnostics). | Finds hidden issues; resets baseline performance. |
Typical battery life: ~500–1,000 full charge cycles (~2–4 years) depending on care and conditions.
How-To: Cleaning, Lubrication, Tires, Brakes, Bolts & More
4.1 Cleaning (The No-Jet Rule)
- Use a bucket/low-pressure hose, bike cleaner, and soft brushes.
- Keep bike upright; power off; ports closed.
- Dry thoroughly—pay attention to battery bay, connectors, sensors, and around the bottom bracket.
- Lightly clean battery contacts with a dry brush; avoid liquids on contacts.
4.2 Drivetrain Care
- Quick clean: Rag pinch the chain while back-pedaling (use a work stand or “walk” mode for hub-drive bikes that don’t back-pedal easily).
- Deep clean: Use a biodegradable degreaser on chain/cassette/jockey wheels; rinse and dry before lube.
- Lubricate: 1 small drop per roller; pedal to distribute; wipe excess to avoid grit.
- Replacement cues: Replace chain when stretch exceeds manufacturer spec to prevent cassette wear.
4.3 Tires & Wheels
- Inflate to the pressure on the sidewall, then fine-tune for comfort/traction. Under-inflation saps range.
- Check tread cuts, embedded debris; consider puncture-resistant tires or sealant for commuters.
- Wheel health: pluck spokes for even tension; address wobbles early.
4.4 Brakes (Pads & Rotors)
- Pads: swap when the friction material is thin or glazed; bed new pads in properly.
- Rotors: keep oil-free; wipe after washes; slight rub can often be trued.
- Hydraulic systems: if lever feel is spongy, plan a bleed (shop task if you’re new).
4.5 Bolts & Cockpit
- Check stem, handlebar, seatpost, racks, and motor-mount hardware. Use a torque wrench to spec.
- Look for cracks or stress marks, especially around racks and cargo mounts.
Battery, Charging, Connectors & Waterproofing
5.1 Battery Care
- Daily use: Avoid deep discharges; keep between ~20–80% when convenient.
- Storage: Park around 30–70% state of charge; store cool, dry; avoid extreme heat/cold.
- Charging: Use the original charger; don’t leave at 0% for long; unplug after reaching target SOC.
5.2 Connectors & Contacts
- Inspect for moisture, corrosion, loose fit; clean gently and keep dry.
- Apply a tiny amount of dielectric grease on metal terminals if recommended by your brand.
5.3 Waterproofing & Washing
- Motors and batteries are sealed, not submersible. Keep away from jet washes and river crossings.
- After heavy rain, dry the bike and check sensor magnets/cables for debris or misalignment.
Software Updates & Diagnostics
- Check your display/app for firmware updates monthly—updates can fix bugs or refine assist curves.
- Error codes: power cycle, note the code, and consult your manual/support.
- Do not open controllers or motors; authorized shops can scan systems and update safely.
DIY vs. Professional Service
When to Go Pro
- Persistent error codes or intermittent power cut-outs
- Hydraulic brake bleeds; fork/shock service
- Motor noises, bearing play, or water ingress concerns
- Wheel builds, spoke replacements, complex drivetrain overhauls
What Pros Do
- Electronic diagnostics & firmware updates
- Comprehensive safety inspection (bolts, frame, wheels, brakes)
- Predictive replacement of worn parts to prevent failures

Troubleshooting: Sudden Power Loss (5 Quick Fixes)
Electric bikes are fun, fast, and functional—until they suddenly lose power mid-ride. If your e-bike is losing power unexpectedly, don’t panic. This issue is common and often fixable at home. Start with these quick checks.
1) Check the Battery Connection
A loose or dirty battery connection is one of the most common reasons for sudden power loss.
What to do:
- Remove the battery and inspect the terminals.
- Look for signs of corrosion or a loose fit.
- Clean contacts with a dry cloth, then reattach firmly.
Tip: A slightly dislodged battery can cause cut-outs even on smooth roads.
2) Is Your Battery Fully Charged (or Aging)?
Even if your display shows full, the pack could be degrading internally. Lithium-ion cells lose the ability to deliver consistent current as they age.
What to do:
- Charge the battery fully and test again.
- If it drains rapidly, schedule a health check or consider replacement.
Search tip: “ebike battery charged but not working” is a common issue—this step addresses it directly.
3) Inspect Your Motor and Wiring
Loose wiring or worn motor cables can interrupt power from battery to motor.
What to do:
- Look for cable damage, fraying, or loose plugs.
- Gently wiggle wires near the motor to test connection consistency.
If your e-bike motor cuts out randomly, start here.
4) Look at the Controller and Sensor System
If your e-bike uses a torque sensor (e.g., VTUVIA models), a misaligned or faulty sensor can send incorrect signals.
What to do:
- Check for error codes on your display.
- Restart the bike and watch for warning icons.
- Consult your manual or contact support with the error code.
5) Check for Overheating During Long Rides
On hot days, long climbs, or heavy cargo, the motor or battery may overheat and trigger a safety cutoff.
What to do:
- Pause and let the bike cool for 10–15 minutes.
- Avoid full-throttle for extended periods.
- Store/charge batteries in shaded, cool areas.
FAQ: How long should an e-bike battery last?
Most packs last 500–1,000 full cycles (~2–4 years) depending on use and care.
Can cold weather cause power loss?
Yes. Batteries are sensitive to temperature; expect reduced power delivery in the cold.
Repair or replace my battery?
If measured capacity has dropped by ~50% and balancing/charging doesn’t help, replacement is typically wiser.
Advanced Setups: Commuters, eMTB, Cargo & Belt Drives
Commuters
- Prioritize puncture-resistant tires and reflective sidewalls; build a weekly 5-minute clean/inflate habit.
- Locking & weather strategy: fenders, chain guard, periodic contact checks after storms.
eMTB
- Post-ride mud routine: gentle rinse, drivetrain lube, rotor check, linkage inspection.
- Check speed sensor magnets/cables after rock strikes.
Cargo & Child Carry
- Shorter service intervals; frequent spoke/bolt checks due to higher loads.
- Brake pad inspections—cargo weight accelerates wear.
Belt Drive vs. Chain
- Belt: no oil; rinse and brush clean; tension and alignment are critical.
- IG hubs: follow manufacturer intervals for oil changes or service.
3 Big Myths About E-Bike Maintenance
- “They’re waterproof, so pressure washing is fine.” Sealed ≠ submersible. Jet sprays can drive water past seals.
- “Always charge to 100% and run to 0%.” Partial cycling is healthier for lithium-ion; avoid deep discharge.
- “If it turns on, the battery is healthy.” Voltage ≠ capacity. Packs can show full yet sag under load when aged.
