Reducing weight is the most noticeable upgrade you can make. Lightweight bikes accelerate faster and are more responsive to the power you generate, helping you reach your performance potential. Lightweight means going faster and further, for longer. We help cyclists reach their goals - from competitive racers to weekend riders.

Most of our bike parts are made from carbon fibre which is lightweight, stiff for optimal power transmission, and flexible in certain dimensions making cycling more comfortable. We put every part through rigorous testing by us and our growing team of cyclists. This means you can be confident that our parts will perform for thousands of miles.

The cycling industry is full of gimmicks, poor quality parts and expensive marketing. We are flipping the switch by working directly with the same manufacturers producing parts for the top cycling brands.

All Litebike products are designed to support a maximum combined rider and bike weight of 100 kg (220 lbs).

We aim to set the industry standard for high quality bike parts that last. We are the opposite of fast fashion. We are slow fashion - for bikes.
