I still think the strida folding bikes are the ones with the highest nerd quotient. Never ridden one myself, but been tempted a couple of times. In particular the low weight compared to any other folding bike is appealing. Unfortunately they are difficult to find for test rides and they look quirky enough that I'd want to do a test ride before buying

The strida is certainly the *dorkiest*, not nerdiest, looking design, but in terms of engineering, it's very bad. It is terrible, TERRIBLE to ride, with horrible mechanical trail. It is extremely unstable. It has no gearing options at all and has essentially no standard parts. It is very clearly the outcome of a designer rather than an engineer ("Let's start with the idea of a bike that folds like a ladder").

There are Strida's with gears.

It's definitely weird to ride -- I would ride it on a commute of more than a few miles. It's less stable than a real bike, but not completely unstable. e.g. I can fall of curbs but can't jump up them.

Most body parts are specialty, not the brakes system, I believe.

It meets its design goals very well: - Internal brake cables and quick release mean it folds very fast and doesn't get tangled up. - It can be rolled around when folded so you don't have to lug it. - It stands tall and thin so only takes the space of a small standing passenger on transit.

That's not what stability is. A stable bike is one in which the steering is stable and easily controlled at various speeds. It's a function of steering geometry and mechanical trail. And the Strida is among the very most unstable folders on the market.

Answer honestly. Would you ride the Strida downhill at a 30 degree incline with a serious curve at the bottom without using the brakes, like you would a mountain bike? How about at over 15 miles an hour [like a racing bike]? A good folder should be able to do both easily.

I ride mine 2 miles a day, sometimes 3 based on a variable commute. Mine doesn't have gears or a spedometer so I can only say I am comfortable at the fastest speed I can pedal -- but it would feel unstable to go much faster, say, on a very steep hill.

I'm not trying to imply it feels like a weirdly shaped mountain bike. I'm saying it does its particular job very well. The seating position and narrow handlebars definitely preclude it doing anything other than getting you from the train station to work on urban streets.

I have a real bicycle, too for, well, actually riding a bicycle.

Unicycles probably have a higher nerd quotient. No folding needed!

When I was at nerd school in the 80s. This was a super-popular intracampus (and occasionally extracampus) transportation option. I never managed to learn myself.
