I've played around a couple of times with the idea of a short custom bike, made to put easily in the back of a car. The intent is that if I'm working out of town, and run across a ride, I'll have a cool custom that I can whip out and join in with. My donkey bike fits this niche now, but I wanted a bike that fits in more with the full stretched customs I often end up riding with. Axle to axle is only going to be about 35", and I'm thinking it'll feature 3 speed Nexus hub, fat rims, folding/adjustable bars, and collapsible pedals. In German, Fahrrad is bicycle, and so Rad is bike. Chen is diminutive, so Radchen is "little bike." I just made that up, but it's a simple enough idea that I wouldn't be surprised if that word already exists.
