This is no suprise to me. I wonder what recumbent bikes get?

Links don't work!

Anyway, this is no shock to me either... now if we could only get a bike to do all of the work FOR us... then we'd be really set.

Yes, and with all the weight you lose, your drag goes down too!

Seriously, though, here in Boston, a land of winter ice and snow, bicycles are just not a year round option. Thus, I'll take my transportation heated, seated, AC'd and CD'd.

Unfortunately the same is true here. I think winter just lasted 6 months this year, which makes me want to cry the more I think about it.

It is most deffinatly an option, NYC and Chicago have the highest number of bicycle commuters in the states. There winters are just as bad, if not worse then in Boston and SLC.

A full winter kit can be had for under $200, that should be good enough for 90% of winter rides. The other 10%? Hopefully you a 2nd option on getting to work. :)

I like riding in the snow though I've never tried it for more than a few minutes. I'll have to give it a shot sometime. As far as economy, I think my bike gets like 20 miles to a cup of coffee or something like that.
