Available in frame sizes of 50cm, 52cm, 54cm, and 56cm. With the growing demand for electric bikes and gravel bikes, it was only natural for Kona to introduce the Libre EL. Built on the wildly popular Libre platform, the Libre EL features an aluminum frame and Verso Full Carbon Flat Mount Disc fork. Like its CR DL sibling, it’s running a Shimano GRX 810 11-speed drivetrain and brakes, and a TranzX + RAD Internal dropper post activated by Shimano’s GRX lever. Unlike its analog sibling it gets a power boost from a Shimano E7000 motor and 504 Wh internal battery. In other words, it’ll get you to the top of that insanely steep hill you’ve been eyeing up, while saving enough in the tank for the long ride home.
