We've posted a few of these photos before, but here is a little series showing how the bicycle increases mobility for those faced with physical challenges. The chap above is dapper and chic on his trike, looking sharp in his suit and scarf. The fact that his right arm is missing is a detail. He still gets around perfectly well.
Cycling while pregnant is virtually a prescription in Denmark. It lightens the load and keeps you exercising and keeps you mobile.
When aging sets in, there are still plenty of opportunities for getting around - and looking sharp while doing so. The bicycle is such a liberation tool to this day, just as it was back it at the beginning of bicycle culture.
Many elderly ride trikes in Copenhagen.
Disabled persons are often seen on bicycles, like this chap with Down's Syndrome at the beach last summer.
If you're 'vertically challenged' as political correctness will have it, there's nothing stopping you from riding a bike.
Even with a leg in a cast, if the injury allows it, you are flying along the bike lanes like there is no tomorrow.
