What our demo riders are saying

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.

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!

Susan T.

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.

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.

Marc Mendoza, founder of Post Carry

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