Riding a bike in winter conditions can add fun, a little suffering (let's be honest) and adventure to your life. Here are some tips to make the most of your winter biking experience.

Ride the paths

After it snows, Boulder includes all multi-use paths in it’s “primary” snow clearing response. The city’s parks and rec department gets an early start on the Boulder Creek path and CU clears all campus paths. Multi-use paths will be clear long before the majority of streets, so try taking the paths as much as possible. Most streets with bike lanes will eventually be plowed, but be on the lookout for clumps of snow in the bike lane and be ready to come to a stop and dismount your bike.

Ride steady

If the surface is bumpy and/or slick, stay loose, keep a straight line and try not to brake. If you know an icy area is coming up, brake before you get to it and coast over it without braking. If you need to brake on a slick surface, only brake with your rear brake, usually on the right handlebar. If your rear wheel slips, you can still recover; if the front wheel slides out, it’s all over. If they are in your budget, carbide studded tires can make riding on ice safer. 

Ride easy

If you are going to ride through serious snow, put your bike in a lower (easier) gear so you don’t get bogged down when the pedaling gets hard. If you typically ride with max air pressure, let a little air out as softer tires are more likely to grip on a soft surface. When approaching rough patches of snow, keep your arms slightly bent and relaxed so you are ready to absorb the bumps.

Be seen

If you plan to ride at night or in the early morning, be sure to keep your front and rear bike lights on and charged. Use reflectors on your bike so that drivers can see you, in the event that your lights stop working. Colorado law requires a front light and red rear reflector; most bikes come with a red rear reflector on the seat post. Many bikes also have reflectors built into the pedals. If you leave your bike parked somewhere, take at least your front light with you as they are often stolen.

Stay warm

Layer up and consider wearing a windproof -- or windproof and waterproof -- shell over your insulated jacket. A light hat or headband under your helmet that covers your ears goes a long way in helping you stay comfortable. On a bike, your fingers and hands will face the wind, so don’t forget warm gloves or mittens. You can make or purchase bar mitts (also called pogies) that attach to your handlebars to give your hands extra protection. Snow or rain pants can help keep you warm, and consider full zip-over pants (popular in nordic skiing and in rain gear) that you can easily remove when going inside. Long underwear can work, but your legs may get hot when you are inside and they require more work to take off.

If you wear snow boots, make sure they have good traction so your feet don’t slip off the pedals and cause a serious injury. Platform pedals with an aggressive tread will help keep your feet secure. Smooth platform pedals, on the other hand, are dangerous when conditions are snowy and wet. If you ride clipped in, there are many shoe covers on the market that can make wearing dedicated cycling shoes tolerable in the cold. It’s generally harder to stay warm when clipped in with metal cleats that conduct heat from your foot.

Keep your bus pass handy

It's a good idea to have a backup plan in case you encounter mechanical or other issues before you reach your destination, that way you can lock your bike and walk, or find a ride. It’s also easy to put your bike on a bus. Bus bike racks can be complicated at first, so watching someone do it first may be helpful. Keep in mind that the bike racks on buses do have easy-to-read instructions printed on them. Something to note: always put the bike rack in the upright position after removing your bike, if there isn't another bike still on the rack. More importantly, for your safety, ALWAYS tell the bus driver you will be taking your bike off the rack as you exit the bus. Google Maps shows bus stops along your route; make sure to find the stop on the side of the street that your bus will be traveling.

Maintain your bike

The best thing you can do for your bike in the winter is to keep it inside. A bike that dries out slowly outdoors will have a lot of corrosion by the time spring rolls around, especially on the chain and the shift/brake cables. If your bike is snowy, brush off as much snow as possible before bringing it in, then make sure you have mats or something else to collect water under it. On those rare days in Boulder when it’s single-digit temperatures and snowy, it’s actually best to leave your bike outside for a bit before riding. A cold bike will have less snow sticking and freezing to it. When your bike chain begins to get noisy, lubricate it with a quality bike lubricant. A "wet" lube will last the longest in wintry conditions.

Have fun and be safe!

Riding in winter conditions can be a blast. The extra challenge presented can make a ride that much more fun. If you don’t typically wear a helmet, well…maybe rethink that for these conditions. Focus and consider that it will take you longer to stop. Avoid riding along heavy traffic when possible. Enjoy the snow, fresh air and the challenge of navigating the less than ideal riding conditions.
