The OPEN U.P. frame

Bikes, Open and simple

Velo Atelier are very proud to be one of only a handful of retailers in Europe working with OPEN. Andy and Gerard's philosophy of only offering their frames through retailers that are knowledgeable and able to properly size, fit and build each customers dream bike to the highest specification, is truly refreshing.

Contact us today to organise a consultation and test ride.

U.P. (Unbeaten Path) and U.P.P.E.R. (lightweight version) combines a performance-oriented cross/road geometry and  parts with clearance for mountain bike tyres. So you can ride anywhere, and ride fast.


Get out of town on asphalt, hit the gravel roads or switch to singletrack. The geometry gets you there fast; the big tyres make you unstoppable.



OPEN's  goal was to build an extremely light, strong and well thought-out hardtail. The result is the lightest 29er hardtail in production, the first frame with internal cable routing that protects while being easy to live with, the first mountain bike with BBright, a frame with a geometry truly developed from scratch for 29er wheels and more.


The hardtail comes in two versions; the sub-900g O-1.0 and the O-1.1 which is barely 100g more. Both frames are available with various build kits.



Andy’s career spans from downhill racer (back when helmets were optional!) to CEO of a mountain road bike company. Gerard’s career includes co-founding Cervélo, where's he's done everything from engineering and design to sales, supply chain and marketing.

OPEN means open to new ideas; from our customers, retailers, vendors and ourselves. Open to show the intricacies of our products but also our company. Open even to issue shares to some of our customers.


If open is the goal, simple is the tool.

“Relentless simplicity” is our guiding principle. Reduce the number of models and you simplify production, logistics, customer decision making, the website, everything. Avoid traditional advertising or sponsorships and free up precious time. Transfer logistics to third parties and you can focus on what matters most, which in our case means:

  • Designing better bikes, the first of which we introduce here.
  • Connecting with our customers.
