Retul Custom Bike Fitters


Custom Bike Fitting Software

Retul's proprietary bike-fitting machines needed a web-based bike configurator. The bike fitting machines send data to the web application (Frame Finder), which uses the data to draw the ideal bike for the rider. Frame Finder then allows the rider to visualize varying sizes of frames and adjustability ranges of parts to select the best combination for optimal fit.

Fusionbox has worked with Retul over several phases. The newest version allows cyclists to virtually "try on" over 200 bike models and 1,000s of components and then shop for the chosen bike parts through an e-commerce system.

We Love Django

Fusionbox has been using Django exclusively since 2013. Django is scalable, secure, and as a batteries-included framework, Django offers lightening fast concept-to-software speed. And because it's written in Python, it's a joy to use.
