a similar affect can be achieved by a car i believe
Now this is a great idea: a bike with a bendy frame that allows it to be literally wrapped around a lamppost and locked up. The flexible frame was developed by DeMontfort University, Leicester final-year BSc Product Design student Kevin Scott and won him a runner's up prize in the recent Business Design Centre (BDC) New …

Most official cycle parking areas provide a cycle rack thus negating the need for any bendy technology. The majority of cycles fastened to lamp posts are probably done so without permission - and a single bendy bike per lamppost that would normally hold 2-3 bikes is a poor use of limited resources!
I've seen them, but used maybe 1 time in 20? 1 in 50? If they're there, great, keep your bike normal...
There's enough places where you have to separately lock the front and back wheels, as they get stolen leaving the rest behind. This locking takes time and gets grease everywhere --- with this system you just need one short chain to lock front & back wheels and presto... If it solves a problem you don't have then good for you.
[In one disastrous address in E9 I've had everything stolen of a bike over the course of a year, from the axles to the little screws that keep your brake linings in place on the handlebars: this problem wouldn't be solved.]
"The majority of cycles fastened to lamp posts are probably done so without permission".
In all the years I've been riding a bike, this is the first time I've seen a suggestion that you need permission to lock your bike to a lamp post.
Where should I apply for permission? Is there a lamp post quango? Do I get some kind of permit, and if so does it apply to all lamp posts or just one?
No instead of attaching two bikes to the lampost you can fit 1!
And for the ones who think it's a breat way to lock up, just buy a bigger lock, it'll be a lot cheaper.
However hats off to him for an original design.
Apple / MS take note, this is what an original, unique design looks like.
Is your priority to show us the fracking bike, or its stout-chested creator? Terrible pic - if that's all they gave you, they need to sack their PR wonks.
"You can lock a regular bike to lamppost of course, by Scott's design takes up considerably less room."
Debatable; the length may be reduced, but the girth will be doubled, which is probably more of an issue for pedestrians. Also a bit inconsiderate to other bikers, as you can get two regular bikes round a lamppost - not so with this.
On the other hand, being able to secure more of the nickable parts of the bike with a single D-lock is appealing.
Just found the original Mail article. Their stats are whack:
So, "more than 52 bikes are stolen in London every day". What's that then? 53? 54? Oh no, wait, just after that we have "A total of 23,748 bikes were reported stolen in London in 2009-10". Well, by my calcs that makes slightly over 65 per day.
At least they're factually right- 65 is more than 52.
Bike Friday also use a cable in tube for bendy frame approach for folding their fastest folder, the tikit:
This seems like a less well developed folding action than the tikit and is solely designed for wrapping around lamp-posts.. why?
I agree with @Kevin Fairhurst
If it didn't bend, you could get 2 bikes on a lamppost, one either side, but this way you can only get 1 bike per lamppost so it's actually worse. And, it doesn't really do anything to enhance a bike's security. A pair of boltcutters are going to have most chains off in seconds even if threaded through both tyres. And, if a thief needs more time with a sturdier chain, all they're going to do is what they do now - thread their chain through your frame to keep your bike where it is til they can get at it at night.
But as a foldable bike for taking on the train it may well be a winner. Cos, let's face facts, those foldable bikes with the tiny wheels are for gimps.
Paris, for promiscuity/bicycle semantic conflation.
in real use that frame will last about 2 months. There is ALOT of stress on the frame of a bike in normal use and I'd hate to be on that when the cable snaps, if you were on a major road that you under a lorry's wheels and dead. At least normal folding bikes don't completely collapse when one part fails..
Nice idea just no way practical I'd say as a cyclist.
Why have you got such a downer on cables? They do things like hold up suspension bridges and there's no reason why they can't be extremely strong. Easy to get one with more cross-sectional area than your average frame tube inside that tube, and the tubular form is not needed because it is a tension element, rather than one which mustn't bend.
A Brompton would also completely collapse if its folding mechanism failed, by the way - there is only one tube (with hinge) connecting the front and back wheels together.
Dunno why I'm posting so many comments defending this bike - I've no connection with it. There just seem to be so many silly objections to it though.
Who is this going to appeal to?
The prize has been given for innovative thinking, but the new thinking here is patently because its a thought not worth having.
People buying bike-shaped objects (i.e. supermarket bike purchasers) won't be interested as they want something that looks like a full suspension mountain bike for £90 (i.e. a boat anchor). They won't pay a penny extra for this technology.
Enthusiast cyclists will have more than one bike and a lock to service them all. Plus frame material and performance is everything, not to mention bike weight.
I suggest the inventor finds another application.
I can just see it. Hurtling downhill at high speed when the cable that holds it rigid snaps.
And as any regular cyclist can attest, every cable on a bike will probably snap at one time or another.
...and I can't say I've ever had any difficulty locking my bike to street furniture that this would make a difference with.
Back in my youth a US company called Slingshot made bikes that folded up with a cable that also provided suspension as well.
Not quite the same, but certainly more versatile than a bike that turns into a doughnut, plus by folding flat they can be attached with a single d lock to a lamp post on only one side.
Paris, looks good on first site but due dilligence is needed before you jump into bed !
Having spent many a year cycle-commuting (OK, mainly summer days only now!), the truth with all folding bike designs is they eventually break around the folding mechanism. In truth, this bendy tube design offers no advance over traditionally hinged frames, and could possibly wear worse over time. With a hinged frame, you actually have to put quite a lot of wear before the frame fails (OK, I admit the first Hercules folding bike I broke failed because I had a habit of making jumps down flights of steps, but then I could do that on an ordianry mountain bike). With a cable-based locking tube, the problem will be if the cable stretches over time, loosening the join and leading to a failure. Just stick to an ordinary, non-folding mountain bike.
That would be true if a D-lock was used. If you used a big chain then you could wrap it round the lamp post before looping it through the wheels - problem solved.
(This also has the advantage of giving you a good workout as you cycle around with a heavy chain draped over your shoulders.)
Where is the "it improves our lives" bit?
I would love to know what "clever and useful ideas" the other students came up with for their final design project at DeMontfort University's if this is the one that got the top prize: a non-returning boomerang, a one-sticked chopstick, an 11-hour watch, an edible chocolate teapot? (The old ones are still the best!)
"But as a foldable bike for taking on the train it may well be a winner. Cos, let's face facts, those foldable bikes with the tiny wheels are for gimps."
As Sublitaratus put it
What impressed me is that the idea could have been had by *anyone* within at least the last 60 years, but wasn't
Thumbs up to the inventor for ingenuity. Naturally how well it actually works will depend on material quality and production engineering, both to fairly stiff cost limits.
That combination of requirements is what usually finishes UK products.
I've been riding a Dahon folder, and I've ridden an A-Bike. The A-Bike didn't work so well because the freewheel mechanism went out, twice. The Dahon has been just fine, with 16-inch wheels, folds up and I stow it under a bus seat. I've never had to put it on the front bus rack.
But where does this stow? Sure, you can wrap it around a post. But you'd have to put it on the front bus rack, and it isn't a conversation starter unless it is bent around a pole, and then you aren't in the area to chat about it. The Dahon, and especially the A-Bike, are fantastic conversation starters.
Those bendy tubes tightened-by-cable are the equivalent of post-tensioned concrete.
Just look at how good post-tensioned concrete is at withstanding off-axis loading: ie, NOT VERY GOOD. In fact, almost explosive: once the load axis departs from the cable axis, the cable actual helps the structure disintegrate.
So, looks good on paper, won't work so good going around corners or over speed humps, eh?
I wouldn't want to test ride it either.... can I have $500?
But, yes, every year some design student wins a prize for a new bicycle design that isn't actually rideable and is never seen again.
"Student Phil Bridge from Stockport is about to complete a three-year degree course in Product Design at Sheffield Hallam University..."
Having said that, I own and am broadly happy with a Strida 3 as a second bike. Even before I put an adapted, double height bin bag over it, having first folded up the handlebars and pedals, I can carry it onto the buses around here, which usually don't allow bikes of any kind, because they can't tell. It looks a lot like a baby buggy.. Shh, don't tell them!
I suppose you can fold up the cardboard bike too - and maybe wrap it round a lamp post... or assemble the Strida around a lamp post and baffle the less intelligent thief.
There aren't crowds of bicycles where I am, and generally you have the lamp post to yourself, as long as the chain fits around. You may need to lift the bike up. It's been suggested that you should spend one-sixth the price of the bike on the chain or lock. I park in public locations, usually in daylight, maybe next to a road junction, and I haven't had a wheel stolen, although I once lost a pump, and once the convex rear view mirror (which I always recommend). Someone working on a chained-up bicycle looks pretty suspicious, I think.
