proteus. bikes for the people.

We are a full-service bike shop with a large inventory of new bikes in all sizes, accessories and clothes, a busy bike fit clinic, and an extensive repair and maintenance shop.  But we try to be more than that. The most important thing to us is that you get on a bike and ride to your heart’s content. We want to make sure you get on the best bike for you, be sure it fits you perfectly, and help you get out and ride in our community.

Thursday nights we’re open late. Come over for food, drinks, and conversation!


what type of bike is right for you?

It can’t be repeated often enough:  The most important characteristic of your bike is that you love riding it!  And the most important thing about loving your bike is how well suits your riding needs and how comfortably it fits your body.

“Just the most knowledgeable, nicest, most down-to-earth bike shop on the planet. I’ve never failed to get solid advice, politely delivered, in every interaction here. This is a local business worth supporting! Amazon can’t make sure the bike fits you like Laurie can.”


Sarah F.

“This is an incredibly friendly and nice shop. I think everyone there wants people to be happy biking at every level, and everyone is super approachable. They always carry nice things too and host social events and rides that I enjoy going on!”

“What a breath of fresh air, this shop is truly a community. Proteus is not like the snobby bike shops where everyone is too cool. I walked in with my bike and baby and within ten minutes my bicycle was inspected and my baby was eating a cookie. After inspecting my bike they even placed it back in my van so I didn’t have to juggle it and my baby. The staff is friendly, the service is great, this is a small business worth supporting.
I look forward to participating in my first Thursday night potluck.”

“I always have a positive experience at Proteus Bikes. I have purchased bikes, accessories, apparel, and repairs and maintenance. They provide the optimal customer service experience in a family oriented and community based atmosphere.”


David D.

“I have kids that are hard core mountain bikers. Laura that service manager was great to work with. Was able to do the front fork work and had a great eye on other safety issues that I asked her about. The staff is great and so is the bike shop I will be using from now on.”
