Limited Handcrafted Motorcycles

The custom bike has been the generic term for a tailor-made bike for several decades. Thunderbike also produces its own frames since 2000, in addition to the numerous conversions on an original Harley-Davidson basis, and has since developed a whole range of different variations. 

From original Harley-Davidson conversions to Suzuki and Yamaha models you will find all conversions in this category that really make the screw heart beat.


In this category you will find numerous Harley-Davidson conversions from our forge. For each bike is a picture gallery created in which you can also find a parts list - with a direct link to our online shop.
