Riding in bad weather is mostly fine and occasionally excellent. Empty paths, nobody else out, and the smug glow of being the one person who went anyway.
It does need a few adjustments, though — and about ten minutes of aftercare that most people skip and then wonder why their drivetrain sounds like a coffee grinder by March.
Wet roads: what actually changes
You stop later
Disc brakes handle water far better than rim brakes, but everything is worse when wet, and an e-bike is heavy. Give yourself much more room than feels necessary, and brake earlier and more gently rather than grabbing late.
If you've been through standing water, a light drag on the brakes for a second dries the rotors and gets the bite back. Do it before you need them, not during.
Grip goes away in specific places
Wet tarmac itself is usually fine. The things that will catch you out are specific and predictable:
- Painted road markings — genuinely slippery, especially large blocks like crossings and cycle logos
- Metal — manhole covers, drain grates, rail lines, metal bridge decking
- Wet leaves — deceptively awful, effectively ice
- The first rain after a dry spell, which lifts oil off the road surface
- Diesel spills, which show as a rainbow sheen — treat as ice
Cross metal and paint upright and in a straight line, no braking, no turning. Let a little air out of your tires for wet riding — a few PSI below your normal gives a bigger contact patch and noticeably better grip.
And turn more gently than you would when dry. Most wet-weather offs happen while leaning, not while braking in a straight line.
You're harder to see
Grey light, spray on windscreens, drivers hunched forward. Run lights in daytime rain — this is the single highest-return thing you can do in bad weather. Night riding and lights covers what to run.
Cold: what it does to your bike
The battery is the part that actually notices.
Expect 20-30% less range in genuine cold. That capacity isn't gone permanently — it comes back when the pack warms up — but it's gone for that ride, so plan the route accordingly.
The rule that really matters: don't charge a cold battery. Charging lithium-ion below freezing causes permanent damage. Bring the pack inside, let it reach room temperature, then plug it in. There's more detail in battery care and range.
Over winter, store the battery indoors at around half charge rather than leaving it in a cold garage full or empty.
Tyre pressure also drops as temperature drops, so check it more often than you would in summer.
Cold: what it does to you
Three things make winter riding genuinely pleasant instead of grim, and only one is expensive.
Cover the extremities. Hands, feet, ears. Your core warms up within a mile of riding; your fingers don't. Decent gloves are worth more than a decent jacket.
Wear less than feels right at the start. If you're comfortable standing still, you'll be sweating in ten minutes, and damp clothing in cold weather is how you end up genuinely cold on the way home. Slightly chilly at the start is correct.
Remember the assist does the work. On an e-bike you generate less heat than you would grinding along on a regular bike, so you need a bit more insulation than a cyclist would at the same speed. This surprises people.
Wind chill at 20 mph is significant. A neck gaiter costs almost nothing and makes a disproportionate difference.
The ten minutes afterwards
This is the part that decides whether your bike lasts.
- Rinse the salt off. Road salt is brutally corrosive and it gets into everything — chain, cassette, brake hardware, bolts. A gentle hose or a bucket and sponge after a salty ride is the difference between a drivetrain lasting years and lasting a season.
- Never pressure-wash an e-bike. Ever. Forcing water past the seals into the motor, battery mount or bearings causes exactly the expensive faults you're trying to avoid. Low-pressure water only.
- Dry it, roughly. A quick wipe of the frame, and get water off the chain.
- Re-lube the chain. Rain strips lubricant off. A wet ride with no re-lube is how chains rust overnight. Use a wet lube in winter — it's stickier and survives rain, where dry lube washes straight off.
- Wipe the battery contacts and the display connector. Corroded contacts cause intermittent electrical gremlins that are miserable to track down later.
Where possible, don't store the bike soaking wet in a sealed shed. It'll rust in place.
Kit that earns its keep
You don't need much, but these three are worth the money:
Full-length mudguards. The single biggest comfort upgrade for wet riding. Not the little clip-on ones — proper ones with a decent front flap. Most of what soaks you comes off your own front wheel.
Waterproof gloves and something to keep your feet dry. Wet feet ruin rides faster than wet anything else.
A jacket that actually breathes. A cheap non-breathable shell means you arrive wet from the inside instead. Vents matter more than a high waterproof rating for riding.
When to just not
Riding in the rain is fine. Riding in these is a judgement call worth taking seriously:
- Ice. Two wheels and ice don't mix, and black ice is invisible. Studded tires exist if you're committed; otherwise this is the one that's genuinely worth skipping.
- High winds, especially crosswinds on a bike with deep panniers or a cargo box.
- Thunderstorms. Obviously.
- Heavy rain plus dark plus an unfamiliar route — any two of those is fine, all three stacks the odds against you.
There's no prize for riding through something stupid. The ride will still be there tomorrow.
