I just wanted to publicise an excellent organisation I came into contact with last year.
Following my brain haemorrhage I became partially sighted, and no longer able to ride a bike......... Until I discovered Charlottes Tandems. ( here's the link)
This organisation loans tandems to disabled people for free. They stock a variety of styles of tandems , for children, for adults , for all ages and abilities and you can borrow them .
The tandem stock they have are all spread across the country, so I'm sure there would be one local to most people if you fancied a go. I would highliy rcommend it!
We borrowed one for a few months, loved it so much we bought one for ourselves, and now have many happy hours travelling on it.
