Description
A common issue with a new bicycle is often the uncomfortable seat. To maximize support and comfort, the bike seat size should match the width of the rider's sit bones. This means that the likelihood of a rider's satisfaction and comfort with the original equipment manufacturer (OEM) seat is generally low, especially for female users. As a result, many users find themselves needing to purchase a new seat to achieve the desired level of comfort.

René aims to solve this problem by providing an easy solution for users to adjust their existing bike seats. Instead of going through the hassle of shopping for a new seat, René allows riders to customize their current seat to better fit their needs and preferences.

Innovation
René is a shape-shifting bike seat designed with size adjustability in mind. The adjusting dial at the back allows users to extend the width of the saddle after purchase to enhance the weight to surface distribution and comfort for riders.
This one-size-fits-all approach makes it a more sustainable choice for bike manufacturers and users, as the OEM bike seats that come with a new bicycle are usually discarded in favour of a more comfortable alternative.
