18" when measured from the centre of the bottom bracket to the top of the post, ie where the seat post goes in.

It needs some TLC, the bottom bracket is creaky , the rear brakes are very hard to apply, the frame is solid as it aluminium, but there is rust elsewhere.
The saddle and 26" tyres are fairly new.

Just thought I would offer on here before scrapping it, I just don't have the time to fix it up, and paying to get it road worthy again, was edging on the cost of a new bike. If you fancy a project, this is for you :)

Bike is at KT3 3EB, please suggest when you could collect if you would like. I would say it is not roadworthy, but could be pushed away.
