Kelvin, if you're interested, their website is at http://www.tramper.co.uk/.
First became aware of them because my partner Catherine got one in 2002 (she has spina bifida) to walk her dogs. She used it almost daily for about eight years until I managed to get her a newer one which does 8mph - her old one was a 6mph version. I reconditioned her old one and have just sold it to someone who lives about six miles from me!
Been working for them as their Scottish agent for almost 7 years now - I do demonstrations to order, and service work on them when requested. Most of the service work consists of an end-to-end check on condition, very few parts ever need replacement in my experience.
Sorry, this post seems to have become an advertisement. I'll shut up now.
