Thanks for posting the pic, Sally. I'm curious why is laid on its side? No kickstand maybe??
I use one that mounts on the rail for the rear wheel, like this :
Wind, I know what you are saying about "Stadtpanzer" (City Tanks). There are several of them around here too. what bugs me is when I see a single person getting out of one in a parking lot.
I mean, its not like I think they should be outlawed or anything. But if you are going to drive something like that have a reason for it. 3 or more people using it.... park in the area of the parking lot for full sized vehicles ( not the compact spaces where they use 2 spots to park one vehicle).
Your sister doesn't like to go very fast on her bike, does she??

I use all of the gears on my bike, mainly because I'm old and don't want to work hard anymore ( if I don't have too, that is). Plus I have an uphill ride to get to the store closest to me, and a downhill ride to get back home. And 2 traffic signals in between. Cops here will give a ticket to a bicycle as fast as they will to a vehicle, sometimes faster ( they know a bicycle won't try to outrun them). And the rules of riding a bike on the city streets are just stupid.
