Cant say enough about the bikes they built or the service they provide. It was an absolute pleasure to meet the team and test ride the bikes. We showed up on a random Thursday night when they happend to be hosting a small buisness event. They welcomed us in and gave us the whole tour. Would have drove one home if they didn’t have to hand craft their bikes for their customers. Shoot guess I’ll have to wait for my one off custom order! Lol

If you’re in the market for a motorcycle, give this company a good long look.

Before during and after my visit I was not disappointed without a doubt this is one of the best handcrafted small displacement motorcycles on the market built in America today if you’re looking for something small agile quick and snappy and just a pure pleasure to ride then this is the motorcycle for you pure riding enjoyment in its simplest form well-crafted well thought-out well-designed for America’s back road and small towns it’s worth the trip it’s worth the ride it’s worth the experience it’s worth what they ask

Fantastic experience today perusing the Janus showroom. Mitch took us through all of the different models and trim and fitment variations as well as a complete tour of the factory / manufacturing facility. A fantastic American made product with incredible attention to detail. Great looking bikes.

We were there for the First Annual Owners community party. It was great to check out the shop. The bikes are great displays of craftsmanship. It is wonderful to have them in the community.

Janus is an amazing small company with a beautiful product. I purchased my Halcyon 250 in November and they sent me pictures of its construction in the shop! No other motorcycle manufacturer can compete with that. Their customer service is on point, Sophie responded to all of my emails very quickly and answered every question I had along the way.

Lastly, when I went to go pick up my motorcycle, Grant was very friendly and helped me understand how the bike works, showed me around the showroom, and overall a cool dude.

Happy to be in the Janus family
