Looks like a good'un, not that I know anything about bicycles.
I do prefer bicycles for exercise over running, because the scenery
changes more rapidly and I feel like I'm making progress... it stops me
from being bored. When I get bored exercising, I just concentrate on how
much it hurts/discomfort, and I don't want to continue.
Hmm, maybe I should start the Distraction+Entertainment school of fitness.
I should be the first pupil!
Ah well stan, after a few months riding that, your power-to-weight ratio
should be massively improved.
