Handmade ATBs featuring the cruiser style

Retrotech Cycles, with a workshop in Napa, California, is a handmade bicycle manufacturer based on the cruiser style, which can be said to be representative of American bicycle culturE The owner-builder, Curtis Inglis, is a self-taught, fully custom handmade bike builder, who has built his bikes based on the information he has gained through his years of experience as a builder.

Of course, he is also a passionate cyclist who organizes single speed championships in his hometown of Napa, and from both sides of the equation, he is constantly seeking to create the most suitable bike for the user's goals and objectives. He is also a supreme personality who strives to share the beauty of handmade bikes with as many people as possible by actively building semi-custom bikes.

The Funduro All Terrain Bike frame is a new standard with 27.5" tires and 148mm rear through axles, but with a slightly longer fork for fun and a more laid-back head angle, and a 44mm head tube for rigidity. The head tube is a 44mm head tube for rigidity.

With a short rear back and seat tubing that is designed to accommodate a dropper post, Curtis has created a bike that is fun to ride and will make everyone realize that the mountains are fun to ridE
