Urbi et Orbi

It is mostly finished.

Urbi et Orbi

Urbi et Orbi, my nonsensical idea for a city bicycle with very, very long legs.

From the front

It combines a flat bar (nice for town) with an aero bar (nice for long, fast rides) for a bicycle comfortable in a wide range of conditions. Early theories included a set of bar ends, but I judged them messy and unnecessary.

Alfine hub

The drivetrain is an Alfine gearhub. There's no practical reason the bike requires one, though they are attractive, and it gives the bike a clean appearance, all-weather shifting perfection, and a perfect 4th (direct-drive) gear.

It is not quite completed: gearing needs to be finalized, and there's a lot of rather shoddy beer-can-shimming keeping parts of the cockpit together. The current weight is about 25 pounds, if my bathroom scale is to be believed. One may think of that as a very heavy road bike, or a very light city bike. Either attitude is acceptable.

The bike does not feel like an easygoing city bike in my quick test ride. It has a sharply-configured cockpit (at least for me), and in the tri-bars, the bike feels fast. The flat bars make for easy handling, but they are narrow, so things are fairly frantic, steering-wise.

It's a fairly ridiculous bicycle, and I think I like how it turned out. Future plans include a chainguard and fenders, maybe. It's not really certain yet.

Bicycle in its natural habitat

I fantasize that this is a bike from a parallel universe, where it was Italy (not England) that developed a TT culture, and that 8-speed gearhubs and aero bars arrived about forty years earlier than in our timeline. The result would be something like UeO, a practical bicycle one could use for commuting every day, but also for time trialling on the weekends. It is retro, but for a past that never existed.

So did you TT on it today?

Yes!

Badly!

The bike was quite effective, though the motor was clearly in crap shape. There's some issues with the handlebars and aero bars, which are more or less bodged together with nearly an entire beer can's worth of shims. I intend to fix that.
