emf Sports started in 2019 as a hobby workshop for a small group of friends to service and maintain their mountain and road bikes. Over a few months, the workshop became a popular venue for local riders to bring their bikes for small repairs, giving them access to tools and a bit of expertise to get the job done right.

In 2020, the workshop had to close due to Covid, but soon after, a new opportunity to help cyclists was discovered online.

The ethos of emf Sports is to keep cycling accessible to a wide range of enthusiasts. So there is no over-priced kit that costs a fortune here. What we do have is tested, proven and unbeatable value kit that we use in our own workshop.
