OK, OK, sorry folks I've never really sold bikes before... ;)
Did some checking last night, and the bikes are 4 years old, bought in Feb 09. Stated millage/usage is correct though.
The ladies bike is actually branded a 'Cadance', and not a 'Cuillin, only differences being the colour, and the Cadance has a slightly shorter stem.
Both bikes are 18", so probably suitable for 5'6" to 5'10" +- a wee bit, there's actually quite a lot of adjustment in the seat post. I'm 5'6" and the seat post is a good 5 or 6" out of the frame on mine.
The bikes are fairly basic and have:
Shimano gears 7 on back, 3 on front.
Tektro V brakes.
Suntour front suspension forks, and cranks.
Mens has £45 Panaracer Fire tires (original tires there too).
Ladies has a Cateye wired computer.
Both bikes have some minor scratches on them from leaning against each other in our old house, but other than that are practically new. Brake blocks, chain gears etc have practically no wear on them.
Hopefully that is better info, I'll arrange some pics for tomorrow.
