after reading about this on a thread somewhere i thought you may be interested in this.
not really invisible, though, is it?
Think of the rotational injuries!
Looks like a convoluted solution to a problem that doesn't really exist. I'm impressed by the concept, engineering and entrepreneurialism though.
not sure how you "Reset" it after though.
Will be bloody warm with a scarf on all the time
Clever stuff, but seems more suited to urban commuting than anything off-road or performance oriented. Presuming it works like an airbag not really much use if there is more than one impact, or against anything other than a large blunt object even if it should stay inflated. However I don't suppose it is meant for anything other than urban cycling so may well fit it's criteria.
Does look a bit warm round the neck mind you!
advantages:
it looks like your not wearing a helmet
disadvantages:
cost!!!
scalf like heat gain
unreliablilty?
resettable?
What happens when I pull a rad and gnarly front flip on the trails and the thing goes off? I won't be able to spot my landing properly!
