RideGetting your fatbike ready for winter
With its fat tyres, a fatbike is really a born winter bike — but cold, damp and road salt are unforgiving for the battery, chain and brakes. With a few hours of attention in autumn you prevent costly damage and ride safely all winter long. This guide goes through every point, from battery to lights, and finishes with a complete checklist.
The battery: the most vulnerable part in cold weather
Lithium batteries hate frost. Capacity drops noticeably in the cold (so a shorter range in winter is normal), but more importantly: charging in freezing conditions can permanently damage the cells. The rules:
- Always charge indoors, at room temperature. If you come home from a cold ride, let the battery come up to temperature for an hour before you connect the charger.
- Don't store the battery below 0 °C. Is your fatbike in an unheated shed or outdoors? Click the battery out and keep it indoors.
- Not riding for a longer period? Store the battery with a charge of about 40-70% — not full and certainly not empty — and check the level every few weeks.
- Use the right charger. The wrong voltage damages the battery; our charger guide explains how to determine voltage and connector. Need a replacement? View the chargers.
Tyres and grip
This is where the fatbike plays its trump card: the wide tread naturally provides plenty of grip. Get the most out of it in winter:
- Ride slightly lower in the permitted pressure range: a lower pressure increases the contact patch and thus grip on wet and slippery surfaces. Do stay within the range on the tyre wall.
- Check the tread: rounded or half-worn knobs mean noticeably less grip, just when you need it most. How to recognise wear and choose the right size, you can read in the tyre guide.
- Due for replacement? View the tyres and grab a fresh inner tube while you're at it.
Chain and drivetrain
Rain and road salt wash away lubrication and let a chain rust within weeks. Five minutes of maintenance once every two to three weeks is enough:
- Clean the chain with a cloth (and, if there's a lot of grime, a chain cleaner or degreaser).
- Then lubricate it with chain oil for wet weather ("wet lube") — it adheres better in rain than dry lubricant.
- Apply sparingly onto the links, let it soak in for a moment and wipe off the excess: an oily chain actually attracts dirt.
- Give the sprockets and derailleur pulleys a quick wipe with the cloth too.
Brake check
Your braking distance is longer on wet surfaces anyway; worn brake pads make that dangerous. Squeeze the brakes and check:
- Is there still at least about 1 mm of brake lining on the pads?
- Does the brake lever stop short of reaching the handlebar before the brake bites?
- Is the brake disc free of deep grooves, warping and oil?
If in doubt, read the brake guide for recognising wear and measuring the disc size, or go straight to the brake parts. Brakes are safety-critical: if in doubt, leave fitting to a bike repair shop.
Lights: being seen in the dark
In winter you're already riding in the dark by five in the afternoon. Working front and rear lights are mandatory and — more importantly — keep you visible in traffic. Check both lights, charge USB lights in good time and replace broken ones straight away. View the lights for headlights and rear lights that fit your model.
Road salt: the silent destroyer
Road salt eats away at spokes, bolts, disc brakes and electrical connectors. The remedy is simple: after a ride over salted roads, rinse the bike off with lukewarm water and a gentle stream — no pressure washer, which forces water into bearings and electronics. Dry it afterwards with a cloth, check the connectors and re-lubricate the chain if you've rinsed it.
Winter checklist in brief
- 1. Battery: charge indoors, store frost-free, keep at 40-70% when stored.
- 2. Tyres: check the tread, pressure slightly lower within the range.
- 3. Chain: clean and lubricate with wet lube every 2-3 weeks.
- 4. Brakes: check pads, lever travel and disc.
- 5. Lights: test front and rear, replace broken lamps immediately.
- 6. After every salty ride: rinse, dry, re-lubricate the chain.
Frequently asked questions
Can I leave my fatbike outside all winter?
Preferably not — and certainly not the battery. At the very least, remove the battery and keep it indoors. If the bike itself is outside, use a cover and rinse off salt regularly to stay ahead of rust.
Why does my battery get fewer kilometres in winter?
That's normal: in the cold, lithium cells temporarily deliver less capacity. Once the battery is back up to temperature, the range recovers. If the loss stays large even in mild weather, the battery may be ageing.
May I clean my fatbike with a pressure washer?
No. The hard jet forces water past the seals of bearings, motor and connectors. Use a bucket of lukewarm water, a soft brush or cloth and an ordinary garden hose on low pressure.
Which tyre pressure is good for winter conditions?
Choose a value low in the pressure range printed on your tyre wall: more contact patch means more grip on wet or slippery surfaces. If you mainly ride dry tarmac, the pressure can go back up. The tyre guide explains the trade-off in detail.
How can I be sure that winter replacement parts fit my fatbike?
Check the specifications: every part lists which models it fits (e.g. a Knaap or OUXI V8) and which size, voltage or connector it uses. Not sure? Ask us — no wrong purchase, not even in winter.
