The inventors of a cardboard bicycle have pulled their campaign to raise more than $2 million to develop a sustainable production line for their unusual method of transport.
The Cardboard Bike - made of recycled materials - was intended to "change the world" by providing a new, clean-energy use for, well, garbage.
The inventors had claimed it could be a transformative invention.
"Imagine a time when every plastic or cardboard product that is thrown into the recycle bin will contribute to the creation of a bicycle, wheelchair or toy," said Israeli engineer and inventor of the cardboard bike, Izhar Gafni, in a press release.
"Basically the idea is like Japanese origami, but we don't compress the cardboard and we don't break its structure. We overcome the cardboard's failure points, by spreading out the weight to create durability."
But after the campaign managed to raise just $41,000, the plan has now been quietly shelved for now.
"We listened to you, our greatest supporters, and will re-open our Indiegogo campaign once the factory is up and running and can offer lower prices and a three-month delivery time. That is the beauty of crowdfunding," said the team on Indiegogo.
So why did it fail? In short, because no one bought the bikes. Only 24 pledges of $290 were received by July 1, which would have guaranteed the backers a bike of their own. After the bike was reduced to $135 more backers came on board - but only another $17,000 worth.
Over at Triple Pundit, Rad Godelnik, co-founder of Eco-Libris, writes:
"The thing is that the market value isn't as important for many people as the value they perceive from the gift. That's where the cardboard bike failed - it just didn't generate enough value to justify the $290 price tag. And ultimately customers weren't interested in subsidising the cost of the factory."
As for the cardboard bike? The team behind it are now looking to develop the idea and factory on their own, before returning to crowd-funding for another go on the merry-go-round.
While it's rather more fiddly than the Nike Fuelband, the UP gives you more control over your data, is a lighter and arguably more attractive device to wear on your wrist and is complemented by 10-day battery and an excellent app which links into several external services to share data on iOS. <a href="http://www.huffingtonpost.co.uk/2013/04/23/jawbone-up-uk-review-can-_n_3139321.html" target="_blank">It's not infallible, but it's an good option if you want to track your activity easily and effectively</a>.
Fitbit One Review
The Fitbit One clips to your clothes to measure the steps you take, stairs you climb, and the quality of your sleep. We prefer it to the wristband version, which lacks altitude tracking.
Nike Fuelband SE
The Nike Fuelband is one of the most attractive and intuitive fitness trackers on the market - and the new SE edition is the best one yet, adding Bluetooth LE for constant syncing with your iPhone, 'Session' markers and limited sleep tracking. It's not a complex gadget, and it's hurt by the lack of Android compatibility. <a href="http://www.huffingtonpost.co.uk/2012/06/20/nike-fuel-band-review-the_n_1612388.html" target="_blank">But it works, is stylish and has earned a legion of fans.</a>
Bose SIE2i Sports Headphones

Sadly, they're not - but they are totally water resistant, secure in the ear and have fantastic sound quality. They also come with in-line controls and a microphone designed for the iPhone, and a fitness armband to hold your music player safe when you work out.
iPod Nano 7th Generation
Apple's latest music player is small, thin, light, has a two-inch screen and is Bluetooth enabled. For our money it's still the best all-around music player if you're mainly using it for exercise - though we do miss the wearability of the 'mini wristwatch' style 6th generation.
FINIS SwiMP3 Waterproof Headphones
<a href="http://www.amazon.co.uk/FINIS-SwiMP3-2G-X18-Firmware/dp/B00822529W/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1369748846&sr=1-1-catcorr&keywords=neptune+headphones&tag=hptech-21" target="_blank">The FINIS SwiMP3 headphones (£93)</a> are a stunning bit of kit which transmit music through your cheekbones via induction. It's one of the only pair of headphones you can wear in the pool, and if you're spending a lot of time underwater and need an Andrew WK boost on your 50th lap, it might make the difference. (£93)
Withings Smart Body Scale
If you want to get fitter, it's worth knowing the state of play before you start - and during your programme. The <a href="http://www.amazon.co.uk/Withings-Black-Wifi-Body-Scale/dp/B002JE2PSA/ref=sr_1_cc_2?s=aps&ie=UTF8&qid=1369748900&sr=1-2-catcorr&keywords=withings+smart+body+monitor&tag=hptech-21" target="_blank">Withings Smart Body Scale</a> will give you that. It's able to accurately track your weight, body fat and various other stats, and sync them to your phone so you can easily monitor progress over time. They're pricey - but they might make the difference.
Many shoe companies boast about the energy-saving, world-changing, etc etc tech of their trainers. The Adidas Boost are the only pair in recent memory that we've been genuinely convinced by. Stunningly 'bouncey' (there's no other way for it), they return more energy to your legs as you run, conserving energy and give you a literal boost to make it that extra mile. Check they're suited for your gait through - they aren't great for those who need a little extra support.
GoPro HERO 3
Alongside being one of the most flexible, durable and tiniest sports cameras on the market, the <a href="http://www.amazon.co.uk/GoPro-Hero-Edition-Camcorder-Black/dp/B009TCD8V8/ref=sr_1_1?ie=UTF8&qid=1369748816&sr=8-1&keywords=gopro+hero+3&tag=hptech-21" target="_blank">GoPro Hero 3 Black action camera (£349)</a> can record in up to 4K resolution. If you're getting fit on a bike, on skis, in the sea, on a board - or doing anything else which conceivably might be of interest to the outside world - you should get one.
