The MoBu, a project led and designed by co-owner and PYGA founder, Patrick Morewood, is the company’s dream and ambition to build the best quality bike in the world using techniques never seen in bicycle manufacturing. The name MoBu is derived from the Sesotho word meaning “soil” or “of the earth”.

Designed with input from PYGA Euro Steel pro-riders and Heinrich Wichmann of Blackstone Tek, who are world leaders in the production of high-performance carbon fiber wheels and components for brands including Ducati, MV Agusta, Arch, Norton, Vuhl and Ariel Atom. The design protocol for MoBu was to improve on their already successful Stage model and to future proof the design. The manufacture of the MoBu will be uncompromising in its execution and provide the ultimate control and fun-factor for amateur and pro riders alike, whilst minimising waste material from manufacture.

Project MoBu is the realisation of a dream to build the best carbon fiber mountain bikes in the world. In order to fulfil this dream, we needed to find a manufacturing partner who shared our passion for innovation and our belief that things can always be done better. Incredibly, we found such a partner right here in South Africa, Blackstone Tek. Throughout the MoBu project PYGA has had access to Blackstone Tek’s unique and proprietary manufacturing techniques that have resulted in a frame that has unparalleled quality, strength and rideability.

Our plan has always been to produce our own bikes right here in South Africa. However, this was not an easy task to accomplish especially when it comes to carbon fiber frames. We’ve always believed in South Africa’s ability to be able to produce some of the best products in the world, as shown by the country’s production of military aircraft and equipment in the 1980’s.

“We’re so confident in Blackstone Tek’s method and precision of manufacturing that we will be offering a lifetime warranty on frame and bearings”

The frame holds two full size water bottles, has a lower shock mount flip-chip and will run a 185mm x 47.5mm length Rockshox Ultimate on the XC/Marathon setup.


In addition to a 148mm boost rear end, the drive-side is offset by 2.5mm to improve the chain-line and rear wheel stiffness while allowing the use of a standard wheel in emergencies.

There’s a two bolt ISCG 05 chain guide mount and all pivots use additionally sealed double-row full complement bearings.
