I remembered that the Telegraph Motoring correspondent was supposed to be building a
Triking , I don't know if he ever finished it and the search facility on the newspaper does not show up an article that he did.

I know that the owner of Triking - Tony Divey had a heart-attack a couple of years ago and the business was up for sale (yes, I was nearly tempted, but good sense prevailed on that occasion) but the company web-site has now disappeared so I don't know the current status of the business.

It would be a shame if it is no longer in existence...
