Welcome to MI MTB 2023

Looking for a recap of the prior seasons?


Yes, we do ride on Mercer Island! We practice on the island during the week by visiting various parks and taking time to develop specific biking skills. We head off Mercer Island for longer rides.


Mercer Island Mountain Biking Advocates

Mercer Island Mountain Biking Advocates (MIMBA) provides a community voice for bikers on the island and is working to ensure we can ride mountain bikes on trails in our own backyard. MIMBA supports the bike team to ensure the team has the resources required for a successful season.

Mercer Island Bike Skills Area

The Bike Park opened on November 15th, 2023! Thanks to the community for supporting this new facility.

Trail Work Events

An important aspect of the team is giving back to the trails on Mercer Island. The team hosts volunteer work events to maintain and improve the trails. The team worked on trails in Pioneer Park and the Mercer Island Bike Park. In 2023 the team has put in over 200 volunteer hours in these locations.
