My apologies my late reply, but I never leave by bike outside. If I go shopping I take in the cart, and if I go into an office I use a carrybag to cover it up.

I had my first folding bike stolen in 2002 ( it was a production sample ). It was sitting outside my adviser's office in the math department at Temple University, and was stolen while I was in his office ( very upsetting, since the math dept is a sacred place for me ).

Thanks,
Yan
