Different riders want different riding positions: some want their handlebars higher for easy cruising, while others want them low for a more aerodynamic position over long rides. Whatever your preferred riding position, you'll be able to find the perfect fit with our Telescope handlepost. The Telescope handlepost allows the stem and handlebars to slide up and down with the touch of a quick release. A majority of folding bikes you see on the market now use this Dahon technology. But the Dahon version is the original and after 25 years of evolution, still the best. Dahon patented technology.
