How do you stay safe cycling in winter?
For winter cycling, run slightly lower tire pressure on snow or fit studded tires for ice, avoid painted lines and metal grates, use bright lights day and night, and dress for the wind chill your own speed creates. Protect hands and feet first. Cold can drain or shut down a phone, so keep yours in an inside pocket. A crash on ice far from home gets cold fast, so set a return time. Holler alerts your Guardians if you are late.
Riding safely through winter
01Set up the bike for grip
Wider tires at a few psi below your summer pressure grip better on packed snow, but go too low and you risk pinch flats and squirmy cornering. For regular ice, studded tires are the most reliable option. Brake early with both brakes, keep the bike upright through corners, and never brake hard while leaning.
02Watch for the slick spots
Painted lane lines, metal plates, manhole covers, rail crossings and bridge decks freeze first and stay slippery. Shaded stretches can hold ice all day even when the rest of the road is dry, and meltwater running across the road at 3 pm is black ice by 5 pm. Cross anything suspicious in a straight line without pedaling hard.
03Dress for the wind you make
Riding at 15 mph adds its own wind to whatever is blowing. The National Weather Service gives the example of 0°F with a 15 mph wind feeling like -19°F, cold enough for exposed skin to freeze in about 30 minutes. Windproof lobster mitts, shoe covers, a thin cap under the helmet and a neck gaiter over the nose matter more than a heavy jacket, which only makes you sweat on climbs and freeze on descents.
04Light up all day
Winter days are short and gray. Run a front and rear light even at noon; a flashing rear mode helps drivers pick you out against snow glare. Drivers have less traction too, so leave more room at junctions and assume a car sliding toward a stop sign may not stop.
05Protect your phone's battery
Apple notes that very cold conditions can temporarily shorten iPhone battery life and even switch the phone off. Keep it in a jersey or jacket pocket close to your body, not in a handlebar mount in the wind, and start with a full charge.
06Plan for being stuck in the cold
A crash or a broken chain on a frozen back road turns into a cold wait. Share a live link and set a return time: if you do not check in five minutes after it, your Guardians get an overdue alert with your location. The CDC's hypothermia warning signs include shivering, exhaustion, confusion, fumbling hands and slurred speech. If you see them in yourself or a riding partner, stop, get out of the wind, add every layer and call for a pickup or 911.
Related questions
Is it safe to ride on snow?
Packed snow can be surprisingly rideable with wide tires. Fresh ruts and slush hidden over ice are the hard part. Ride slowly, stay loose, and walk the sections you are unsure about.
What should I carry on a winter ride?
A spare dry base layer and gloves, a tube and a pump or CO2 you can work with cold hands, a snack you can eat in mitts, and a charged phone. If you flat in the cold, your sweaty layers chill you fast while you fix it. The solo cycling safety guide has a full kit list.
Can crash detection help on icy roads?
Holler's crash detection (beta) looks for a hard fall followed by stillness and asks if you are OK before alerting Guardians. It can miss real crashes and can false-alarm, so treat it as a backup to your return time. If you do go down, our guide on what to do after a bike crash walks through the first minutes.
