The innovative bike, which locks by removing the seatpost and slotting it through the downtube, is unable to be unlocked without rendering it unusable, as potential thieves would have to break either the seatpost or the downtube. The downtube itself has a collapsible point in the middle, and the two sides pop out at a 90 degree angle for the seatpost to slide into. You then lock and unlock it with a key, or even with Yerka’s app via your phone.
Yerka say of the bike: “The main goal of this project was to produce the most secure bicycle system ever created without affecting the integrity of the frame itself,” says the company. “We realised that performance and comfort can be achieved together which is why the beauty of Yerka’s design is in its simplicity. By thinking out of the box we came up with a concept that merges everything into one sleek design.”
With the delivery date due for September, customers can start-pre-ordering now with a discounted price, with the single speed version available for 599 euros and a three speed for 699 euros. In addition to this Yerka have set up a referral program, whereby if you refer enough friends who follow up with a purchase you can get a bike for free.
The Yerka project was successfully crowdfunded via Indiegogo, a crowdfunding website similar to Kickstarter, in 2015. The campaign raised over $98,000 to put the bike into production, 35% more than their target.
After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He was Staff Writer at 220 Triathlon magazine for two years before joining road.cc in 2017, and reports on all things tech as well as editing the road.cc live blog. He is also the news editor of our electric-powered sister site eBikeTips. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
