Handlebars come in variety of sizes, so the design of the product will have to be universal enough to fit all of the diameters. It will also have to be light and easy to install in case the user would like to take it on or off the bike at any time.
Most of the bike accessories consist of two part attachment, which includes a holder fixed onto a bike and the accessory that can be clipped in and out of the holder.
In this example, the holder is usually made out of plastic and includes a set of rubbers that help with adjusting it to the correct diameter. The accessories that include this kind of fixture are usually a little bit more expensive. I would like to keep the cost of my product to the minimum, in order to encourage more cyclists to use it.
A slightly lighter example of fixtures available on the market uses a thick rubber band that is stretched and usually hooked onto the two opposite ends of the product:
This is an interesting example, however it seems too bulky for the Bike Pin product.
I decided to reduce the fixture to a simple piece of a flexible cord:
The cord has to be fixed onto one end of the product. Initially I attached it to the back wall of the product, but after consulting my supervisor I changed it to a hook structure emerging from the bottom surface. This proved to be a stronger solution, which is crucial as the user will be pulling on the cord in order to attach it.
The cord, in form of a loop, will then be hooked onto the front fixture of Bike Pin:
This is a lightweight and effective solution, that is very quick to install.
