What our riders are saying

I fear I have developed a superiority complex because I see all other bikes, especially the $12,000 bling-bling road bikes, as ridiculous now. The impression I have is that if chased no one would ever catch me because I could just bunny hop over the curb and set off into woods before anyone even knew what happened. This bike screams capability.

Exceeds all expectations. The bike is basically perfect.  Smashed a bunch of PRs with my out of shape for the holidays legs.  Due in part to its just so damn fun to ride. Joy = speed it seems. This thing is a thoroughbred.

I’m a typical, skeptical mechanic. I’ve worked on and ridden every gimmicky bike in the book. I've never seen one this well thought out.

Aaron C.

Hands down some of the best people. If you’re looking into getting a bike... get in touch with Randall. His business and their mission are truly all about the end user and a flawless end product."

Matt E.

If you’re looking for one bike to do everything, this bike can do a lot. I can’t think of a trail or road where I wouldn’t have a ton of fun riding it. I could ride uphill forever on this thing!

Usually a new bike feels a bit foreign, but the OB1 made sense to me from the second I strapped it on, even though I've never ridden a bike remotely like it. The bike was an intuitive fit from the first pedal stroke: the way the geometry felt, the way it responded to my inputs, the component choices and the way those components worked together.

Joshua S.

Both the front and rear ends felt stiff under power when I needed it, like on the road bikes I’m used to, and it was just so fun to shred fire roads and singletrack.

Damn it. I don’t want to ride my regular bike now.
