BYKD.INC was registered in the USA in 2015. It is a manufacturing company which is specialized in the development and production of innovative bicycle accessories for riders from all over the world. Customers from more than 100 countries are already enjoying our first product - Rinsten Spring, which gets more and more popular on the market. All our activities started a few years ago. Our team has carried out a campaign on Kickstarter. And it was a success! Just for one month more than 2500 Backers believed in our idea and helped to present the world Rinsten Spring. Rinsten Spring is a universal bicycle shock absorber - an innovative bicycle accessory, designed to make rides smooth and comfortable. It minimizes bumps and vibrations from any kind of road from tarmac to hill path, pave stone or gravel. Using Rinsten Spring the back literally "sticks" to the seat and it doesn't shift, so it allows applying less effort while riding. Rinsten Spring is the only one bicycle shock absorber in the world which suits almost all types of bicycles, can be used by children from 2 years old with a weight from 10 kilograms (22 Lbs) as well as by any age adults with the weight up to 150 kg (330Lbs). Rinsten Spring is the only one bicycle shock absorber on the market which works in 3 dimensions (while pedaling, the saddle moves with the hip joint, reducing rubbing and as a result increasing comfort). All this makes Rinsten Spring very unique on the market. We have the patent for Rinsten Spring in the USA, Europe, China, Australia. Trademark Rinsten was registered in USA, Europe, Japan, South Korea, Mexico, Australia, China.
