So you bought yourself a cardboard helmet a few years back and have been waiting for the opportunity to pair it with a bicycle of similar construction? If this (somehow) sounds like you, then the man you need to talk to is Israelite Izhar Gafni, who regularly transforms $10 worth of reinforced paper into two-wheeled vehicles.
As you can see in the clip, the majority of the bike is made of cardboard, however, Gafni adds a coat of paint for aesthetics purposes — and probably to help protect it against the elements. In addition, a rubber ring is fitted around each wheel, though sourcing recycled ones is entirely possible. It can support weights of up to 140kg, which is more than sufficient to carry the average person and will happily soldier on in hot, cold or wet conditions.
Sadly, unless you're willing to do the work yourself, a 'board bike like Gafni's would set you back anywhere up to $US90, the artisan says. On the other hand, if your Stanley knife skills are up to snuff, then you might be able to transform $10 of cardboard into a similar product. If you do, be sure to drop us an email!
