Lennard Zinn has been designing and building great bikes of all types for big and tall cyclists since 1982 at Zinn Cycles. He is one of the few bike designers in the world that has dedicated his career to improving the performance and durability of big and tall bikes. There are many more factors to building a big and tall bike than most people understand. It is not as simple as just scaling up a “normal” sized frame and calling it good. When you do that, several things happen to the bike. First, the stretched out tubes become less stiff, which results in high speed frame shimmy. This is a scary by-product of a poorly designed bike. Second, the added material makes the bike heavier, especially if the builder tries to solve problem number one with just using bigger heavier tubes. Third, without a fork with a long enough steering tube, the handlebars will be far too low for the tall cyclist causing discomfort in the back, neck, wrists, and arms. Fourth, building a bike for a tall rider with average length cranks will make the rider feel like he’s pedaling a kids bike while sitting up very high. Lennard has developed great frame design concepts to address and solve all of these issues and more. A bike designed by Lennard Zinn will be stiff and strong, while remaining lightweight. It will never shimmy at high speeds, and all of the components will be proportional to the rider. Fit, performance, comfort, and durability will all be superior on a Lennard Zinn designed bike than a big and tall bike from any other designer out there. We guarantee it.
