The Rinsten Spring Production Update


Dear Friends!

The aluminium parts of the Rinsten Spring is in manufacturing process.

The next step is painting.

Unfortunately, we faced with a unexpected problem. Just imagine, we have found a suitable factory and they sent us the samples, that samples were good and suddenly this factory was closed. The reason is that such factory didn’t pass the environmental check of their production. We were forced to look for a new one, that would meet our quality and production requirements. And fortunately we have found it! We are waiting the samples to be painted at the moment. 

Also, in parallel, the packaging is manufactured for dispatch.

We are doing everything to have time to finish the production of the party before the Chinese New Year.

In addition, we met with one of our bakers who came for tourism in our city. It was very exciting to show the first production model to someone who believed in us before production began.

Thomas then sent us his impressions, with which we proudly share with you:

“I was very impressed by the Spring, even this first version without the last improvements. I looks robust and doesn't give the impression it could break. As I couldn't try on a bike, I can only guess the comfort improvement it will make and I'm looking forward to trying in on my hard commuter bike. Especially good in my opinion are the safety caps which really look good and functional: design is refined and looks really premium,  brightness is very good and it is easy to switch the battery whenever needed. The finish of the Spring is very good and I'd be eager to see the painted versions.” 

P.S. Thank you Thomas! We were glad to meet you!

Friends, despite all the delays, the difficulties we face on our way, we are all doing this for you! And, only thanks to you we will succeed!

In addition, we do not stop testing springs for strength. And, specially for this, we developed a press that helps us check the springs.

The load reaches 300 kilograms.

Real quality warranty


Dear Backers! 

Thank you very much for your support and patience! 

We understand that for some, to start production seems like a very simple and quick process. Unfortunately, it's not right. Searching for reliable partners and conducting numerous tests took a very long time. 

During the test period, we encountered several problems. One of them was the propensity of metal to corrosion. To protect Rinsten Spring, we decided to zincify all springs. We want you to enjoy riding your bike with Rinsten Spring for a lot of years. Zinc-plated springs will not allow the metal to rust and will make the springs more resistant to any weather conditions.


To our regret, the bicycling season in the northern hemisphere has already finished. We really sorry for the season without Rinsten Spring. We decided to support our backers and extend "the 30-days money back warranty". We give you an opportunity to test Rinsten Spring after the start of next season in your country. The return guarantee will be valid until May 1, 2018.



We sincerely thank you for supporting our project. 

Best Regards,

Your Rinsten Team
