Keeping your bike well maintained is, in general, essential to safe riding, but in winter conditions, it’s even more important. In addition to checking tire pressure and making sure it’s accurate before you head out for a ride, check your antifreeze level. Antifreeze should be changed yearly, and if you take part in winter rides, changing it at the start of the cold weather season is a good idea. Be sure to check that all your hoses and your chain are in good shape. If anything looks questionable, repair it or replace it.
