This isn't a bike though... It's a nearly custom fit medical device they'll use most of their waking hours where bad fits can cause permanent damage to their bodies. Their configurator has ~25k options just for the frame fit ignoring colors and all the other parts of the wheelchair.

Would you be willing to spend all day every day on it?

Would you be willing to pin your entire ability to leave home on it?

My bike cost £30 (because I got it from a bike charity that sells excess donated bikes to the public to raise funds)

As of today, the cheapest adult bike-shaped-object in Halfords is £116. It's another £35 if you want them to assemble it, although Halfords are infamous for having pictures of incorrectly assembled bikes in their own catalogue

A decent bike for a child costs more than that these days in North America.

You either bought this bike used, stolen, in 1989 or are trolling.

was it new?
