Biking in the snow and ice is hard on your bike. If you have a nice bike, we recommend storing it and picking up a beater (aka cheap bike) for winter commuting. You may also want to use cheap old-school components.
Install Knobby or Studded Tires
* In mild conditions you can use low-pressure knobby tires on both the front and rear wheels.
* In severe conditions, winter tires with hardened steel spikes and a wide tread pattern will clear snow and increase traction on packed snow and ice. Basic studded tires have around 100 studs. More expensive models have up to 300 studs for better traction.
* The key to control and traction is the front tire. So place a studded tire on the front wheel first before investing in a studded rear tire.
* On my bike I have solid knobby tire (700 C X 38C) on the front with a knobby tire with a ride line in the back (700 C X 38C)
Prepare the Frame and Components
Snow, slush, salt, and sand can make short work out of a steel bicycle frame (another good reason to store your good bike for the winter and pick up a used one).
* Touch-up and repaint all scratches and dings to retard the onset of rust. This is not necessary if you have an aluminum frame.
* Repack your bearings.
* The truly dedicated can wax the underside of the frame with basic car wax. This will resist snow and slush build-up.
* Once a week give all drainage holes and the seat posthole a blast with WD-40. This can prevent water from freezing inside your frame.
* Give most of your bike's moving parts a blast of WD-40. Products like WD-40 are great for loosening rusted, stuck, or stiff metal parts but are not ideal as a lubricant for bike chains and derailleur. WD-40 may also help to loosen brake cables, clipless pedals, cogs, freewheels, or other frozen parts.
* Clean the chain set regularly. Expect your chain to take a beating over the winter and be prepared to retire it after a season.
* Chain Lube Purple Extreme Lubricant is what I have been using and it rocks!!!!!!

* Carry a lighter and a small bottle of lock de-icier in case your brakes or moving components freeze-up. But be careful with the lighter so you don't melt any plastic or rubber parts.
* During warm spells, wash your bike with hot water and let it dry before you take it out in the cold. (Bring the bike inside and give it a shower & rub it down)
* Note bike should be dry before putting outside again
Choose the Right Parts
Brakes
* Brake pads with curves in them scrub away mud, and work better than other brake pads in wet weather.
* Most bikes have aluminum rims, although some have steel. Steel rims tend to ice-up and don't brake as well as aluminum.
* After 5 winters on a bike & if you use V-Brakes then get eagle claws 2 (

Fenders
* Close-fitting fenders can clog up with slush, ice, and snow and impede your progress. Fenders that clip on the down tube and seat post provide good protection and plenty of clearance. Make sure your fender on the front fallows the tire (fender attaches to fork & not to the frame of bike). For the back one make sure it is fully covering you from the spray (if not add a piece to extend the fender…plastic is the best to use).
Lights and Reflectors
* Short days and falling snow or rain can drastically limit a driver's visibility. Use a powerful, highly visible front light or flashing white LED. And at least two bright red flashing LED rear lights.
* Most winter riders use two bright red flashing rear lights because batteries can fail in cold conditions.
Winterize Yourself
Once you've got your ride in order, take stock of your own gear for protection from cold, snow, and wind.
* Watch the weather forecast, and factor in the natural wind chill and the chill that's generated by your riding speed.
* Set a personal comfort zone or cut-off temperature. For example, if the weather drops below -15 degrees Celsius when it's windy or snowing, you may choose not to ride. If it's sunny and -25, you might opt to ride out.
Body Protection
Dress for maximum visibility. Bright colored garments accented with highly reflective tape are ideal. There are also a variety of personal flashing red LED lights that mount quickly and easily to the back of your helmet to add extra security.
For truly foul weather, well-layered clothing is the easiest way to regulate body temperature and stay dry. Even though it may be very cold outside you will perspire if you are riding hard, so try not to overdress. In dressing you have to stop two things wetness & wind. If you have all these covered you should be fine.
* A thin moisture-wicking layer against the skin moves perspiration away from your skin and keeps you dry.
* Above your wicking layer, an insulating breathable layer like a midweight or heavyweight fleece is ideal.
* As an outer layer we recommend a wind-deterrent jacket or shell. Some people even use old ski jackets! You'll probably also want shell pants. Warning: Your outer layers, attacked by road salt and slush, may get wrecked.
Protect Your Extremities
Cold extremities can turn a pleasant winter ride into an endurance-fest. Frostbitten toes and fingers can cause problems for years. So, to protect yourself, take care of your head, face, neck, eyes, hands, and feet.
Head
Not only does your head need to be safe, it needs to be warm. You'll need a helmet with adjustable pads that can accommodate headwear. Remember that cycling helmets must be replaced after a single impact. Toques, headbands, and cold water paddling caps work well under a helmet. Ear covers that attach to your helmet also chic and cozy. To keep your face and neck protected, use a balaclava, neck warmer, or scarf. Make sure you can breathe well through the material!
Eyes
Blade-style glasses or goggles will stop your eyes from watering (and eyelashes from freezing) and keep flying road grit out of your eyes. A must for year round biking (dark for day and coloured ones for night (yellow, clear and orange)
Hands
Any warm, windproof gloves will do. Lobster-claw-style cycling mitts offer maximum warmth without sacrificing dexterity. The ultimate in cold and wet weather hand protection are cycling pogies. Pogies (if you are really hardcore…but would not use it fro couriering) fit over your gloves, your bike's shifters, brake levers, and handlebars to completely seal out the elements. What ever gloves you pick has to fit well & not put pressure on the nerves in your hands…if after awhile your hands go numb then you know the gloves are no good)
Feet
Wet feet equal cold feet, and cold feet can lead to a cold body. Wet shoes also dry slowly, so at the end of a long workday, putting on your cold, wet shoes can dampen your enthusiasm for winter commuting. Here are some solutions:
* Winter or Hiking Boots You can dust off winter boots or grab your hikers, slap them on, and ride to work – a great solution if you have a fairly short, low-intensity commute. For long distances or in busy traffic, bulky winter boots may not offer the performance and response you need to ride safely.
* Plastic Bags An inexpensive and simple solution is to put a small plastic bag over your feet or inside your shoes. A great short-term fix if you get caught at work and the weather turns nasty.
* Gore-Tex® socks A more sophisticated option that is warm, breathable, and waterproof, but still doesn't solve the problem of perpetually wet shoes. This is a must for any winter biking (frozen wet feet sucks!!!!!)
* Booties Neoprene cycling booties are made to keep your feet as warm and dry as possible under bad conditions. Waterproof overbooties made of moisture-repellent packcloth keep your shoes and your feet dry and comfy. Remember, even with booties on, you'll need warm socks.
* Gators covers the ankles & shines stops snow & water from getting into boot or shoe
Riding Tips
Winter conditions offer a unique set of challenges to the bicycle commuter. You must be a defensive cyclist and anticipate possible problems. Keep these tips in mind next time you head out in less than idyllic weather.
* Choose your route to work based on the winter road conditions. If you are confident riding in traffic, busy streets tend to have the least amount of snow and ice. However, be aware of huge, tire-swallowing potholes, slush puddles, and snow banks. Also remember that snow-covered roads mean narrower thoroughfares. So be vigilant in busy traffic and never assume that drivers can see you.
* Less traveled roads and bike paths are generally safer but can be covered with hard pack snow and ice. Riding on rutted ice and hard pack snow is extremely challenging. If you choose a route less traveled, plan to add more time to your commute so you can slow down and ride carefully.
* Ride slow, steady, and smooth. Try not to make sudden emergency maneuvers. Keep your head up and anticipate the next turn when you will need to brake. Remember wet, slushy, roads mean reduced stopping power and extended braking distances. This also applies to cars in front and behind you.
* You may want to pedal in the same low gear all winter (mostly used gears are 4,5,6 in the second ring. In slushy and/or snowy conditions your cogs may get gummed up – your gears can skip or freeze in place. If you’re frozen in low you can still pedal in most terrain. When it is snowing getting into your higher gears will not work due to the snow buildup near your frame
* If you start to loose control, aim for a snow bank. It will still hurt when you run into it, but it beats sliding helplessly into an intersection or a parked car.
* Modulation in your petal stroke can get you past anything
* Black ICE or any types of ice if you hit it do not try to turn off it. Just let your motion carry you forward. Relax your body & expect to bail off your bike if things start going wrong
* Quick easy bail move…….put hand on front of the seat between your legs and push. You will clear your bike as it moves forward. This little move has saved my life a couple of times. Your bike can be replaces where as you can not
