I have a 2003 Gazelle Impala that I got from a grad student headed back home. It *is* hard to find out about them even online... I'm lucky because there are 3 of 'em (at least) in town and my LBS has the guy that worked on the other two (and maybe this one, I dunno) so he knows things like what size tires those are in American units.
Somebody's blog referred to this bike model as a "Bike on Tranquilizers" and I sort of agree - it does not accelerate fast Still, it is definitely designed to get me there - smoothly and elegantly. Fritz, the cycling maven and closet hero who got me in contact with the owner (okay, I walked into the shop when they were both there talking about it) said it was the proper bicycle for formal occasions... so I rode it to his memorial service and I often think of him when I'm riding it.
