Cool in a fairly uncool sort of way, bit Jones,! ducks head for the fall out & barrage of abuse. I might buy it if i was loaded!!! But I'm not so would be too worried about breaking & replacing a spoke let alone trying to find a new tyre or tube. Wouldn't mind having a go on it though!!
I REALLY want one built up custom to my dimensions. I think it would just look like a 29er does to normal height people. Something like a 26" TT and a 24" seat tube, with big riser bars on it and no toe overlap.
