Cyclo, a foldable helmet made out of recycled ocean plastic, is crowdfunding on Indiegogo

Well good on them for doing something practical with all the tonnes of ocean plastic, but I'm not sure the space saving is that revolutionary. You've still got the same length and width as you would with the top flipped. I realise it might make the difference for some people, but I doubt enough people to make it profitable.

With a lot of products seeking investment on kickstarter etc, it's up to the investor to do their due dilligence the same as any company would when considering whether to invest in something, if the people seeking funding don't provide the required information then it should be enough to put you off rather than just hoping to buy a shiny and interesting product.

SpeedX - remember all the inches of pixel space used up by people argueing and waxing lyrical about how brilliant SpeedX was - about how much it was going to change cycling - about how much of a dipstick you were if you didn't invest into their brilliant bikes now..... you don't see many SpeedX's around do you.... well you could.... there's a field in China with 800,000 of them rotting away and unknown numbers of people stupid enough to invest their money who never got a bike from a bankrupt (morally and financially I would argue) company with unfullfilled pledges and unpaid suppliers and no returned deposits.

I made the mistake of backing one thing on one of these please finance my idea schemes and when I eventually recieved it, nearly 2 years later, it lasted less than 2 weeks before water ingress turned it into a non functional brick... it was a waterproof rear light and it cost me nigh on £50 and those behind it refused to refund me. Its replacement cost me £9.99 off Amazon and it is 3 years old and still functions every morning I switch it on.

I'd be dubious about buying any supposedly safety product from a company that makes no mention of testing on their web site, and three out of five people demonstrating it in their video are wearing it tilted too far back on their heads.

If a bicycle helmet, even the very best, makes you feel safe in traffic I think you are probably deluded and have grossly over estimated their efficacy.
