How do you stay safe bike commuting in winter?
Winter bike commuting is safer with studded or wider tires, full fenders, bright lights for both dark ends of the day, and a route that gets plowed early. Leave more time so you are never rushing on ice, and take transit on freezing-rain days. Keep your phone in an inside pocket, since cold can shut it off. Share your commute with a Guardian and set a return time so Holler alerts them if you do not arrive.
Commuting through the cold months
01Build a winter commuter
Studded tires make the biggest difference on ice; fit them before the first freeze rather than after the first crash. Full fenders with a long front mudflap keep slush and road salt off your feet and the drivetrain. Salt corrodes chains fast, so rinse and lube the bike every week or two, and consider a cheaper second bike for the salty months.
02Rethink the route
Your summer route may use a bike path that nobody plows. Main roads are cleared first but have more traffic and narrower lanes because of snowbanks. Find a winter route that balances both, check your city's plow priority map if it publishes one, and ride it once on a weekend after each big storm.
03Light up for both commutes
In midwinter, many commuters ride to work at dawn and home in the dark. Use a strong front light, a bright rear light, and reflective details on your ankles and pedals. Carry a backup rear light, because cold drains light batteries too. Our guide to bike commuting at night covers light choices.
04Leave early and ride slow
Rushing on ice is how commuters crash. Leave ten minutes earlier, brake early and upright, and avoid painted markings, metal plates and streetcar tracks. The evening ride is often icier than the morning because the day's meltwater refreezes as the sun goes down.
05Dress for arrival as well as the ride
Layer so you can unzip as you warm up, and protect hands, feet and face. The National Weather Service recommends loose layers, a water-repellent outer layer and mittens over gloves, and changing out of wet clothes promptly. Keep a dry base layer and socks at work in case you arrive damp, because damp clothes on the ride home are how commuters get chilled.
06Share the commute and set a return time
Apple notes that very cold conditions can temporarily shorten iPhone battery life or turn the phone off, so carry your phone against your body and charge it at your desk. Share a live link with a partner or roommate on dark commutes and set a return time. If you do not check in five minutes after it, Holler sends them an overdue alert with your location.
Related questions
Is winter bike commuting worth it?
Many riders commute all year with the right setup. The key is judgment: ride on cold, clear days and take another option in freezing rain, fresh ice or a storm that has not been plowed yet.
What is the most dangerous winter commuting hazard?
Ice you do not see, especially refrozen meltwater in the evening and shaded corners in the morning. Drivers skidding in intersections is a close second, so give cars extra room and do not count on them stopping at the line.
Can my partner see if I am running late?
Yes, if you share a live link, and they will get an overdue alert if you miss your return time. The live page shows how long ago your location last updated, so a dead phone looks different from a slow ride. See our page for bike commuters for a full setup.
What should I do if I slide out on ice?
Get yourself and the bike out of the traffic lane first, then check for head, wrist and collarbone injuries. If you hit your head or cannot ride safely, call for a ride or 911 rather than pushing on in the cold. Our guide on what to do after a bike crash walks through the first minutes.
