My dad bought a new Trek Fuel EX 5.5 2009 through the cycle to work scheme and for one reason or another has never ridden it. It's just over 12 months old and has been used once by one of my pals.

Due to bad health it's likely he will never use it and sadly it's too small for me. I'm 6ft 2ish and I think the frame is 18.5.

Is there any bike shops that would do a part exchange?

And roughly how much do you think it would go for second hand?
