Rinsten news

Hey guys, sorry for not giving updates for so long. We hope that you’re all healthy and able to ride a bicycle freely during this worldwide quarantine.

We are here to tell you how things are going.

In September last year, we were at the Eurobike 2019 in Germany and after that, we had more than 30 companies, who were interested in selling Rinsten Spring in Europe. During half of the year, we negotiated with them, but they did not lead to anything, because there is a fake in the market, which people buy, thinking that this is the original, as sellers of the counterfeit stole not only our design but also content from Kickstarter.

Sellers of fake sell the product of low quality which carries a mortal danger in itself for cyclists. We use safety caps which sturdily twisted on the spring, which in no case will fall, and the counterfeits’ caps are made from ordinary plastic, which is installed without a thread and can easily fly off with your seat and you can get hurt.

We have patents in Europe, China, Australia and we are waiting for the US patent to be confirmed. We started the process against the fakes in Europe and we found out is that the largest part of the fakes is being sold through Amazon, some through eBay and Aliexpress, and some European buyers buy on other resources. We began to file complaints on Amazon, eBay, and Aliexpress, and some of our requests have already been deleted. It is strange that Amazon and Aliexpress remove some sellers and some do not, although they have the same product. We started working with lawyers to completely ban the sale of fakes, which will undoubtedly increase our sales and, in turn, will lead to the speedy fulfillment of our obligations to you. And ultimately, you all get your rewards, we are also waiting so much for this moment and to see you all using Rinsten.

If you will see those Chinese fakes, please write to us with the link as it is very important for us. Also, if you can give us the contact or a piece of advice about legal services in Europe and the US against counterfeits, we will be so grateful for that. Guys, who can help us in this process, we'd really appreciate it.

We are happy and grateful for your belief in our project, which makes us do not give up on our idea. And anyway we will be grateful for your support for the shipping, that we are able to ship you immediately. Here is the link:

Feel free to write about other details, we are also looking forward to sending all the springs to you. You can write here or directly to email [email protected]

We wish you all and your families to be healthy and thanks a lot for your big support!

Once again, I'm sorry that we haven't fulfilled our obligations until now.

Sincerely yours,

Iurii Kopytsia

Hi dear backers!

After the update 1 month ago, we received a lot of positive comments from you. We appreciate you a lot for your support and understanding. You backed our idea and we were not able to fulfill the obligations in time. We are sorry.

Rinsten is a small team and we do everything possible to send rewards to all of you ASAP. As we told you previously, we had some problems with the production and we lost pretty much money and time.

Some of you asked if there is any way to help us so we could ship your rewards faster. We would appreciate your help a lot and that is why we have created the pledge on Backerkit where you can pay the shipping fee of $12 and get your Rinsten Spring faster. 

Thanks for your support!

A rough time
over 4 years ago – Wed, Jul 03, 2019 at 12:59:32 AM

Dear Backers!

First of all, I would like to say thank you for your support!

I was trying to do the best and fulfill all the obligations in the planned quantities and time.

As you can remember, the first batch was defective because of the process violations of the production by the factory, so we had to dispose of the entire batch. Because of that, we had to start all from the beginning and it was a big loss of time and money.

I expected to start selling Rinsten Spring in November 2018 and that I earn enough money to cover all the costs of shipping to you.

But today, after all, what we went through, I am in the situation where I need to sell three Rinsten Springs in order to be able to ship one reward to you, our backers. 

I really need your support today once again!

I know that many of you are very tired of waiting for your rewards, some of you are very angry and upset, and please know that I understand you. And I do everything possible so you could get your rewards as soon as possible. Please, I ask you to understand that this is Kickstarter, and creating something new is always difficult. When you back a project, you’re not buying something that already exists. You’re supporting a creator’s right to try to make that thing—and agreeing to go along for the ride. My way of creating was hard, but I do not give up. And I promise that every backer will get his reward for sure.

We send all the rewards to the backers in small batches and just in black color. It is hard to predict how things will go at this moment. 

I want to let you know that I appreciate all of you because without your support I could not do anything! But I still ask you for a bit more patience and understanding. Step by step and soon all of you will be riding a bike with Rinsten Spring installed. I hope to do it very soon.

I will keep you updated on our progress.

Thanks a lot!

Founder, Iurii Kopytsia

We didn’t post updates all this time because we directed all our efforts and time to produce the batch of the springs so we could be able to start shipment as soon as possible.

It was a very eventful time. Our CEO and CTO spent two months in China. They were doing a constant monitoring of all steps of the production. Also, we have implemented the video control from the factory to automate the process of production.

We have been experimenting with a lot of types of paint coating and its quality and have found the best one. Moreover, now we use stamp marking on the springs instead of laser engraving. This method of application increases the anti-corrosion properties of the coating

Production process
over 5 years ago – Sat, Aug 11, 2018 at 01:14:19 AM

Hello Dear Friends!

Please accept our apologies that we didn’t post any updates for so long. We had a lot of work and channelled all our resources into production.

What did we do?

First of all, our engineers made multiple tests with different heat treatment conditions to choose the most optimal for our steel. And we found one. We had a lot of scientific work. We changed the technology of production. Springs have become much more reliable.

We found another painting factory and made samples there. Quality of painting is much better than previously.

We started the process of deleting of the frauds. It’s not so easy and needs time. But, we already stopped selling in some shops and relentlessly continue working on it.

And naturally, an update on the refunds status. Friends, we are trying to refund ASAP. Some of you already received their money. But it’s difficult for us because production of the new batch needs investments and we invest all money into it. We are doing our best to send your pre-orders by the end of August and we are on schedule to meet this deadline. If anything will change in our schedule we will inform you immediately about that.

Once again, we are very thankful for your support. It’s not just the words, it’s really important for us to know, that so many people trust us. Many of you sending us emails with kind wishes and words of support. And every time those words of reassurance make us work even harder to deliver on our promises soonest and simply make us happy. Thank you!
