Its sleek and clean look is complemented by an internal cable routing system, which prevents cables from interfering with any added bags on the handlebars. This enhances both control and comfort, providing a smoother ride on a variety of terrains. Every detail has been carefully crafted to combine both aesthetic appeal and practical functionality.
Electric Upgrade-Ready for Easier Riding
Designed with long-distance cyclists in mind, this folding gravel bike features enlarged cable holes to support rear-drive electric assist kits, allowing you to easily convert it into an electric bike. The battery is removable and does not interfere with the folding mechanism, so you can recharge on the go. Whether you’re tackling rugged trails or spending hours on the road, this bike makes it easier to ride long distances with less effort. More than just a gravel bike, it’s a versatile folding bike combining mountain and road bike performance to take you on new and exciting adventures!
