New Bike Concept - Would You Ride It?

Siechotic

From the site:

"Nulla is one way of saying “nothing” in Italian. Bradford Waugh named it that way for lack of central hubs or chain-drive, giving it a very minimal visual weight. “Ditch that fancy car and buy a stylish bicycle”, this is what you are going to say once you have this one with you. With such a clean, simple and sleek look, this bicycle is surely going to change your mind whether to buy a car, or bike or bicycle. This futuristic bicycle provides deep coverage, good appearance and comfort perfect for riding and skating. However, it is not sure whether you will have a safe riding with this kind of seat on a bicycle. Let’s wait for this concept to come on roads."

Those wheels would have to be super strong to not buckle under either the weight of the rider or pothole induced stress.

Does look good though!

An interesting design exercise but I doubt the materials exist to make this a practical proposition. Imagine the stress on the wheels, and what kind of gearing would be required to drive the rear wheel at the rim?

Special K

At least double the rolling resistance, non?

I didn't realise you got concept bikes. Looks like fun.

I'd give it a go - although the reach/wheelbase look absurdly long and I share the aformentioned concerns about how it would be geared up enough to move at any speed. A cool bit of design though.

I wonder if the seat platform and down tube (leading to direct drive assembly on rear wheel) can be adjusted to suit the rider? That would be cool.
You have to admit that there wouldn't be such an issue with side winds if your bike doesn't have any spokes or hubs

Monty Dog

Keeping the back wheel straight would be immensly difficult - the amount of leverage vs the amount of engagement would make it very difficult to keep the wheel inline.

fast as fupp

it would collapse if i mounted it! :twisted:

touchy

you'd never be able to get a valve on a wheel like that either?

I certainly remember an article on the "polo mint" front wheel some time late 80s early 90s in cycling weekly. A research student in Hull uni I think created one. I seem to remember it looked very much like a modern deep dish aero wheel (50-80mm deep) with no hub or spokes obviously, built in carbon. The tyre revolved around on a bed of bearings and as far as I know the guy raced it in TTs. The tyre may have been solid. F**k knows where I come up with these memories. Anyway it was at the time when British cycling inventions aka G Obree were being banned by verbruggen and his mates so even if it had been a goer, I'm pretty sure it would have been consigned to the "plucky enthusiasts" scrapheap.

It looks like someone had taken a softride or Zipp and stuck ridiculous wheels on it.


It doesnt look particularly efficient with regards to frictional losses. Cool concept, but no use whatsoever in the real world.

It's horrible. I'm turning into man from UCI I know - but most modern bikes really don't do anything for me anymore. I want a more traditional frame with steel tubing, lugs and have spoken directly to the person building it.

I'd have a go if it actualyl existed. It looks just like a computer generated theoretical concept model to me that will never be produced.

quite cool tho.

Thats just lies
A* on your project though

On a 'real' road, I can imagine all kinds of debris and dirt getting caught in the inner teeth of the wheels (esp. when going through puddles and the like). Which will then hit the drive cogs to form a nice grinding paste , or worse if it's a stick or a stone.
