We are celebrating our Birthday in the US: is two years old.  We are celebrating our anniversary by offering a special edition bike.

Our vision was simple: To build one of the most advanced 20" bikes ever!


The WOOM 4 Carbonara Di2 special edition with a 20" full Carbon fiber disc brake with electronic Shimano XTR Di2 11-speed shifting.  

The Frame and Fork

Frame and fork are made out of super-light carbon fiber material.  Both frame and fork are hand painted in Austin TX with a high quality clear matte coating.  Hand painted in Austin, TX by Austin Paintworks  

The Cockpit 

The Shimano PRO Tharsis XC Stem is married to a Di2 trail riser bar with a XTR Di2 display.  The XTR 11-speed Di2 shifters are combined with XTR M9020 brakes.  

The Seat and Seatpost

The Di2 battery is neatly hidden in the seat post.  Our WOOM saddle is light and adjustable.  

The Drive

The single 34T Wolf crank is married to the 11-speed XTR Di2 drive train and makes this bike the ultimate riding machine.  

The Wheels

The super light Carbon Fiber rims are hand painted with a matte clear coating. Tire options range from super narrow Continental Grand Prix tires for riding on smooth surfaces to 2.1" wide Kenda tires for going offroading.
