Alter Events

We believe that cycling is just as much about camaraderie as the activity itself.



Every Friday 5-7pm since 2013 |  HAPP!EST HOUR

Join us every Friday of the year for our "HAPP!EST HOUR!" cycling community gatherings along with Sklar Bikes.

We believe strongly that the future of brick and mortars in any industry depends on being active builders of community. We must not be the only ones that think so. Spaces and moments that gather diverse folks around commonalities are essential.

That said, come on by any Friday. Local beer from Outlaw Brewing and LaCroixs are on us - we’re here hanging out with all our friends talking at laughing about life and occasionally bikes. Once in a while we throw a story night, fundraiser or a late-night DJ set into the mix. We’ll be sure to let you know about anything cool via our Instagram

All nice folks, kiddos and dogs are welcome.


When in Bozeman- Alter Cycles Supper Club Shred-35.jpg

Tuesdays in Season at 6pm |  SUPPER CLUB SHRED

We’ve always felt the moments surrounding any bike ride with friends is just as good, if not better than the actual time in the saddle.

Come hangout in the woods and let’s play bikes! Every Tuesday during the dry months we load up 6pm here at the shop and head for the hills, ride bikes and BBQ while the sun disappears behind the mountains. It’s a really fun time.

Focused to the average trail-bike rider, these rides are about having fun out in the woods with 5 to 50 of your friends.

Weather dependent with a different trail every week - make sure to follow our Instagram or call the shop the day of for updates.
