We came up with something so easy and simple, yet extraordinary! Unlike traditional locks if a thief tries to steal a Yerka, he must break the frame, the most essential component. This leaves the bicycle unusable and the thief empty-handed.
When the frame is in its locking position, blocks the crankset too. If by any chance the thief breaks the structure your YERKA was secured to, he won´t be able to ride it. The lock features a reinforced collar over the keyway and high security discstyle cylinder for increased protection. We also added crossed bolts in each pivot so that no one can disengage the locking arms.
In addition to its innovative safety system, fine components and a weight of 26 pounds, it is
remarkably easy to use.
We removed complexity and preserved the essentials. Shimano Nexus incorporates the gears sealed inside the hub which results in low maintenance and technical service in addition to greater reliability. You can change gears without the need to pedal!
3 speeds: one for flat surfaces, for slightly steep climbs and the third to increase speed.
We know you are tired of carrying heavy locks everywhere you go. With Yerka you’re going to ride comfortably: no more heavy locks, no extra accessories, no extra weight! Removing complexity and preserving the essentials means less maintenance & technical service too.
