I won't be attempting that, it will be rolled up but I will need a 120 cm ramp rather than an 80 cm ramp like I had planned. A 4-1 ratio provides a nice gradual ascent.

Took this picture during the week still have to do the ramp which I started to day, and the top which will be a dark wood not the light wood you see.

This was mine. Used a car jack to lift. And a metal ladder to get the bike on the lift. 25mm ply wood. Ordered off ebay was about £300 delivered about 6 years ago.
