Use this once at the start of winter, then scan it monthly. Each step includes quick checks, actions, and what to buy if something’s off.

At a glance (what “good” looks like)

Battery charges at room temperature, holds charge predictably, and connectors are clean.
Tires show no sidewall cracks; pressure set slightly lower for grip; tread matches conditions.
Brakes bite early and evenly; rotors run true; pads have ≥1 mm friction material.
Lights are bright, well-aimed, and survive rain; reflectivity visible from the sides.
Drivetrain shifts quietly under load; chain wear ≤0.5% (on 11/12-speed ≤0.3%).
Bolts are snug to spec; wheels straight; no play in headset, bottom bracket, or hubs.
Cables/connectors are strain-free and weather-protected; display shows no error codes.
Suspension moves freely in the cold; fenders don’t rub; no salt crust on exposed parts.
Short shakedown ride confirms smooth braking, shifting, and stable electricals.
You know your winter range baseline (Wh/mi or Wh/km) and carry a simple repair kit.

JUMP TO:

Tools & supplies (keep on the bench)

Hex/Torx keys, torque wrench, chain checker, tire pump with gauge, brake cleaner/isopropyl alcohol, shop towels, wet-conditions chain lube, light threadlocker, dielectric grease, anti-seize, cable ties, spare tube/patch kit, mini-pump/CO₂, nitrile gloves, small brush.

Step 1 — Battery & charging habits

Check

Visual: no swelling, odor, leakage, or heat spots.
Charge behavior: charges normally indoors at 15–25 °C (59–77 °F).
Connectors: clean, tight, no greenish corrosion.
State of charge (SOC) after storage: still within expected range.

Charge and top-off at room temperature; never fast-charge a cold battery.
For weekly riding, keep daily use roughly 20–80% SOC.
For multi-week storage, leave ~40–60% SOC and store cool/dry.
Wipe contacts, add a thin smear of dielectric grease to exposed low-voltage plugs (not on high-voltage blade contacts unless specified by the manufacturer).

Fix/Buy if needed

Certified replacement charger (match voltage & connector), battery cover/insulating sleeve, fire-retardant charging mat, smart outlet/timer.

Step 2 — Tires, tread & pressure for winter grip

Check

Sidewalls for cracking/cuts; tread depth; embedded debris.
Pressure with a reliable gauge (expect to run 5–15% lower than summer for grip).
For snow/ice: consider winter compounds or studded tires.

Set pressure to the maker’s safe range for your load and terrain; verify before each ride.
If you ride regular ice, choose studded tires (front first, then rear).
Carry a spare tube even on tubeless setups (sealant can fail in extreme cold).

Fix/Buy if needed

Winter/studded tires, quality gauge, tire levers, sealant, tubeless repair plugs.

Step 3 — Brakes: pads, rotors & feel

Check

Pad thickness: ≥1 mm friction material (not counting backing plate).
Rotor true: no rub-rub sound when spun; no blue heat spots.
Lever feel: consistent bite point; no squishiness (may indicate air/contamination).

Clean rotors with isopropyl alcohol; bed-in new pads (10–15 firm stops).
Realign calipers: loosen, squeeze lever, re-tighten evenly.
If hydraulic and lever pulls to the bar, bleed per manufacturer spec.

Fix/Buy if needed

Sintered pads (better wet performance), fresh rotors, bleed kit/fluid (correct type: mineral/DOT), rotor truing fork.

Step 4 — Lights & 360° visibility

Check

Front light bright enough for your speed; beam aimed to avoid dazzling.
Rear light stable/flash mode; visible from 100 m+; side reflectors intact.
Mounts tight; IP-rated for rain; cables tidy.

Run front + rear lights at all times in winter gloom.
Add reflective tape to fork blades, crank arms, seatstays, and helmet edges.
Consider a helmet-mounted light to “look through” corners.

Fix/Buy if needed

High-output bar light, dedicated tail light with daytime flash, reflective stickers, USB charging dock.

Step 5 — Drivetrain: chain, cassette & shifting

Check

Chain wear with a checker (replace around 0.5%; for 11/12-speed many replace earlier).
Pulleys spin freely; cassette teeth not shark-finned.
Shifting under load smooth; no skipping.

Degrease and re-lube with wet-conditions lube; wipe excess.
Index shifting: a quarter-turn on barrel adjuster can cure most minor hesitations.
Replace chain proactively to protect cassette/chainring.

Fix/Buy if needed

New chain, lube, quick links, pulley wheels, cable/housing kit.

Step 6 — Frame, wheels & fasteners (the quiet safety)

Check

Wheels: spin true; no side-to-side wobble; spokes evenly tensioned by sound/feel.
Headset: hold front brake, rock bike—no play.
Axles/through-bolts, stem/handlebar, seatpost clamp, racks/fenders: snug to spec.

Use a torque wrench; follow the manufacturer’s torque values.
Anti-seize on steel-into-alloy threads; light threadlocker where specified (e.g., rotor bolts).
Re-tension fender stays to prevent tire rub.

Fix/Buy if needed

Replacement bolts/washers, torque wrench, anti-seize, threadlocker.

Step 7 — Suspension & contact points

Check

Fork/shock cycle smoothly in the cold; seals not weeping.
Set sag appropriate to your weight with winter clothing.
Grips dry and tacky; contact points comfortable with gloves.

Add slightly slower rebound for icy chatter; temperature can thin/slow fluids.
Consider pogies/bar mitts, insulated gloves, and wider pedals or pins for winter boots.

Fix/Buy if needed

Service kit/seals, winter-weight gloves or pogies, grippy pedals, comfort saddle.

Step 8 — Electronics: wiring, sensors & display

Check

Harness routing: no tight bends; no crushed sections under zip-ties.
Connectors: seated fully with gasket lips in place.
Display/controller shows no error codes; speed sensor aligned to magnet.

Add a tiny bead of dielectric grease around low-voltage connector gaskets.
Secure loose wires with soft straps; avoid sharp edges and fork crown pinch points.
If firmware updates are supported by the brand/app, apply stable releases before peak season.

Fix/Buy if needed

Replacement magnet/sensor, spare display mount, gentle cable sheathing, extra zip-ties/Velcro straps.

Step 9 — Weatherproofing, cleaning & salt control

Check

Fenders cover at least 40–50% of wheel arc; mudflap near ground.
Drip lines: water doesn’t flow toward connectors.
Salt residue on fork crown, chainstay bridge, motor casing, and kickstand plate.

Never pressure-wash the motor/bearing areas; hose on “rain” setting or bucket + sponge.
Rinse salt promptly; dry and re-lube chain the same day.
Clear frame film on rub points (cable slap, bag straps).

Fix/Buy if needed

Full fenders with stays, frame protection tape, gentle bike wash, corrosion inhibitor (frame-safe).

Step 10 — Shakedown ride & winter range baseline

Take a 10–20 min ride mixing climbs, stops, and steady cruising.
Listen for rubs/clicks; re-check rotor/pad clearance and fender alignment.
Log distance, watt-hours used, average speed, temperature, and wind.
Compute Wh/mi (or Wh/km) to set your personal winter range expectation.
Pack a simple winter kit: tube, levers, pump/CO₂, multi-tool, tire plugs, gloves, space blanket.

Outcome

You now know how far you can go today in your local conditions, not last summer’s.

Quick troubleshooting table

Symptom	Likely cause	Fast fix
Sudden 20–30% less range	Cold-soaked battery, soft tires, headwind	Charge indoors, insulate battery, add 3–5 PSI, reduce speed by 2–3 mph
Brakes squeal when wet	Contaminated pads/rotor, glazed pads	Clean with alcohol, lightly scuff pads, re-bed
Light flickers on bumps	Loose mount/connector	Tighten mount, re-seat plug, add a drop of dielectric grease
Random cut-outs	Loose battery, pinched harness	Re-seat battery, inspect cable pinch points, add soft ties
Chain skips under load	Worn chain/cassette or mis-index	Replace chain (check wear), fine-tune barrel adjuster

Optional add-ons that pay off in winter

Studded front tire (control the steering on ice), then rear if budget allows.
High-output front light + separate tail light with daytime flash.
Full-coverage fenders with mudflaps.
Pogies/bar mitts to keep fingers functional for braking.
Dielectric grease and frame protection film.

FAQs

Q1. Can I charge the battery in a cold garage?

Charge at room temperature whenever possible. If the pack is cold, bring it indoors, let it reach room temp, then charge.

Q2. What’s the best storage level if I won’t ride for a few weeks?

Around 40–60% SOC in a cool, dry place. Check monthly and top up if it falls below ~30–40%.

Q3. Do I really need studded tires?

If you meet black ice or packed snow regularly, yes—start with the front tire. If roads are mostly wet/slushy, a winter tread with lower pressure may suffice.

Q4. Can I hose-wash the bike?

Use bucket/sponge or a hose on gentle “rain” flow. Avoid blasting bearings, motor seals, and connectors.

Q5. How much range will I lose in winter?

Plan for a 15–30% reduction depending on temperature, wind, and tire choice. Your own Wh/mi baseline from Step 10 is the most reliable guide.
