Concept Bikes & Bike Innovation - for better or worse

No, they would only clang against the supporting post when turning the wheel.

You could store the bikes perpendicular to the face of the wheel if you clamped them rigidly, but clamping a bike up is a hassle/can damage the tubing, and you'd still have to wait for other people to finish using the rack before you could use it yourself.

Isn't it meant to be a piece of art, anyway?

Hipster powered ferris wheel? Guy on the left...

Guys guys guys this almost doesn't look terrible. No seat high adjustment though...

Where is the brakes?

Good point, may need some very clever cable routing to allow the folding to still happen.

Maybe that is why they are not there...

Folds up pretty small. Not as small as a Brompton, but the wheels are larger and it might ride a bit more like a 'normal' bike.

On the other hand, it looks like it takes quite a long time to fold - perhaps if you want a folding bike that rides like a normal bike, a Dahon or Airnimal is a better choice.

Interesting, though. Anyone seen this:

A nice-looking and quick-folding bike. It doesn't fold up very small though.

^ slack chain

That silver folder looks like it would be super flexi to ride. Too much design, not enough engneering.

36kg fully-tilting pedelec - sounds interesting, even if the weight sounds a bit optimistic

looks horrible to pedal as well, why didnt they make it semi recumbent or something?

I don't know. That's how I designed mine ^^^

i like this thread

One of those 'you've got a week left at the end of term and you're not allowed to waste it' projects.

Stick an internal gear hub into a wheel and drive it directly with the pedals = bike that folds smaller than a Brompton. No, I don't know how the hub would work.

I guess the cranks would have to engage something like a freewheel mechanism on the hub, but how you would change the gearing is a mystery to me.

What happens to your legs when you want to turn a corner. Calf overlap?

haha, oh dear

Surprisingly there shouldn't be any calf overlap - if you watch the front wheel of your bike, it doesn't turn past a few degrees except at below walking-pace. You don't get calf overlap when riding a penny farthing, either. Not that I've tested it or anything... it's just a fancy sketch really.

... it's just a fancy sketch really.

And significantly better as a starting idea than anything I could create from scratch.

As it's just a concept, I'll stop critiquing.

The crank doesn't look long, maybe 150mm, still usable.

it's possible to have an internal gear on a direct drive bicycle, unicycle have those for a while;

Surprisingly there shouldn't be any calf overlap....

Actually I just realised the fucking obvious.

What used of a front suspension if your feet is on the wheel? what happen when the fork depressed when you're pedalling?

I dunno. I did think about it briefly and decided that 30mm of travel wouldn't be that bad. I thought about ways around it (like the outer hub suspended around the inner hub...) but nobody else has even mentioned it. Like I said, it's just a fancy sketch. "Styling exercise", to utter the immortal get-you-out-of-anything deus ex machina words. When you scribble something together in two or three days, it either works good or it looks good, unless you're amazing and can do both at the same time.

I didn't realise those hubs existed. Only 1:1.5 ratio so you'd be spinning a 24" gear, but the technology exists, so I suppose it could be made with a different ratio and you'd be away. Cool!

Top-tube may well be adjustable, but there's a lot of toe overlap even with the top-tube set nearly horizontal. Plus the usual issues of flexy frame.

Oh, god.

I thought I'd resurrect my project-thread.

This is a pretty awesome idea, if totally impractical.

It's in German, so I apologise to everyone but Schick.

hehe I wonder how long it took them to find the right sized lamp post
