I was up at the scrap yard, er junk yard, today. I saw this kids trike.

I tried it for size. but Im 5 foot 8, 1.7metre. so too big.
I was wondering if anyones modded these type of things. stretch the frame to fit an adult.
I got a mtb frame and a hybrid wheel, at the scrap yard. they were £1.50. So I think the trike would be about £5. Dont think a welder would charge too much to stretch the frame
