World's First 'Unstealable' Bicycle Is Essentially A Giant Padlock

This is the Yerka, and it claims to be the world's first 'unstealable' bicycle. A bold claim it might be, but when security is as well and truly built into a bicycle as the Yerka you'll start to see what they mean.

The Yerka doesn't come with a bike lock, the Yerka is the bike lock.

Designed by Chilean inventors Cristóbal Cabello, Juan José Monsalve, and Andrés Roi Eggers, the stroke of genius that makes the Yerka work is that for a thief to steal the bike they would have to physically cut through it - thus rendering it ultimately useless.

The team's initial ambitions are small, hoping to sell just 300 bikes per month worldwide. However that hasn't stopped them having big thoughts about the future.

Looking for $1m in investment, the group of friends hope that the bike can become a worldwide hit, especially when you consider its current price tag is just $500.

The response to the bike's innovative design has been mixed with some questioning whether the design would ultimately stop a thief on the grounds that it still requires a conventional padlock.

Yerka's answer is that because the padlock is built directly into the design the thief would still need to irrevocably vandalise the bike in order to steal it, ultimately ruining any hope of selling it on.
