If you've ever tried to cycle in a skirt, you'll know that it can be quite a revealing experience.
So a group of Scottish cyclists got together and decided to do something about it.
They found that a simple penny and elastic band combination could be used to transform any flowing, non-cycle friendly skirt into a loose pair of shorts, preventing it from blowing in the wind. They named the discovery "Penny In Yo' Pants".
The idea emerged at the world's first Cyclehack.
Johanna Holtan, from Edinburgh, and Sarah Drummond, from Glasgow, chatted about their experiences of cycling over a coffee and decided that they wanted to find a mechanism to bring people together to positively address cycling issues.
They were joined by Glasgow School of Art graduate, cyclist, and designer Matthew Lowell and the result was Cyclehack: an event where cyclists come together to develop "tangible prototypes" that make it easier for people to get on their bike. The movement subsequently went global: this year, a series of coordinated Cyclehacks will take place in 35 countries between Friday 19 and Sunday 21 June.
The Cyclehack team announced their penny + elastic band hack in a video that quickly went viral.
It's since been viewed 3.4 million times.
There was one drawback.
The penny and rubber band method caused unsightly skirt creases, so the design team (Alec Farmer and Madeleine Wilson from clothing line Trakke, and Cyclehack founders Sarah Drummond and Johanna Holtan) attempted to solve that problem.
The result was a prototype faux leather puck and aluminium coin that fits neatly onto the skirt without wrinkling the material.
The Penny In Yo' Pants team hope the invention will make it easier for women to take up cycling.
