My uni goes to slow so I thought it would be awsome to equipe it with gears. The only way I could see it working though was on a girafe, but I still could not see where to put the shifting gears and the shifter. I would prefer to have a regular sized (a few feet tall) uni with gears. The problem the gears would have to be small so I wouldn’t get going as fast and I wouldn’t know where to put any of the gears or the shifter. If anybody has built or boought or has an idea about building or where to buy please don’t hesitate to inform me.
