Shop Rides 

Tuesday & Thursday Evenings


Join us for our Tuesday night MTB rides or Thursday night for our gravel rides! MTB rides meet at 6:15pm at the (pre-determined) trailhead and gravel rides meet at the shop at 5:45pm. This season we're partnering with MAMBA and riding a variety of great, local trail systems. Mountain bike rides are roughly an hour and a half and the gravel rides range from 15 - 25 miles. Follow @BikeMAMBA and @onionriveroutdoors on social media to get updates and location info! 

A couple notes regarding group ride safety: Face-coverings are required and we'll maintain safe distances at all times. That means no pace lines on each others' wheels and safe (and legal) distancing on the roads. If you feel sick or have been exposed to someone who's sick, please stay home. Front and rear lights are highly recommended and required if we're out 1/2 past sunset.

What type of bike is needed for our gravel rides? While there are bikes designed specifically with gravel riding in mind, we like to say that "gravel" is a road surface, not necessarily a type of bike. Mountain bikes will be fine on our rides, as will flat bar hybrid bikes with at least somewhat knobby tires. Road bikes with at least 30-32mm tires will work. You'll want low gearing for our hills. Average pace will depend on who shows up and whether or not we can split into two or more groups. We'd like to have 10mph pace and a 15mph pace if possible, though group cohesion is the goal here, not crushing mileage. We look forward to riding with you this season!

Muddy Onion 2022: Saturday, April 23rd

New and improved for 2022: THE WEATHER, and a lack of pandemic viruses. OK, we can't 100% promise that, but we're hoping conditions aren't quite as epic as the cold, rainy 2019 (the event lived up to its name!) or the virus-which-shall-not-be-named of 2020 and 2021. To relive the muddy fun of 2019, take a gander at Alex Geller's imagery HERE

Come out of your winter hibernation for a fully supported gravel grinder covering (almost) all of the amazing dirt roads Central Vermont has to offer. It's not easy, but it's definitely worth it. For those who are just getting their bike legs under them, there is a shorter loop that will still give you plenty of dirt, fun, and cow sightings.
