Your dream bike has arrived.
OB1 is the one bike you'll take on every road. It’s a sleek road bike that shreds gravel, and a CX racer that loves to travel. It packs a carbon frameset, a choice of road or gravel carbon wheels, and an uncompromising component spec that won’t let you down.
It's the dream bike we built for ourselves, and we want you to have it too -- at a fraction of the usual cost.
How It Works
Let's reimagine how bicycles are built.
THESIS is a direct-to-consumer bicycle company based in California. Our name comes from a belief that thoughtful curation, evidence-based engineering, and operating with transparency and integrity are key to building a great bicycle company.
So we built personal relationships with the leading factories in the industry, and we created a customizable bicycle with superb components. And we cut out all the middlemen to bring you the OB1 for an unheard of price.
THESIS is the brainchild of Randall R. Jacobs, a former professional cyclist, serial entrepreneur, Mandarin-speaker, and supply chain architect who has spent the past 17 years building and riding bicycles for a number of industry players. We’re proud to partner with leading manufacturers, innovators, and advocacy organizations to advance cycling experiences and accessibility.
