What kind of bikes are you winter riders using?
I use a 1960 girls Meteor Flite (even though I am a man). My riding is mostly in the city.
I like it because the top tube doesn't get tangled in my legs when the ice is bringing me to the ground. It also has a coaster brake which doesn't freeze up like caliper brakes do.
The tires are 1.75" wide which are wide enough for winter riding, but more narrow than the typical 2.125" tire, so it is a bit easier to handle.
Best of all, it only cost $5.00, so I don't have to cry when I see the salt from the roads eating it up. I have heard of wome winter bicyclists using their expensive mountain bikes for winter commuting. This is hard to understand considering the damage that the salt does.
