- Robin Wallner, Ibis cycles Enduro race team


”The reason the Kalk works so well is the use of a frame, a motor, suspension, wheels, tires, and cockpit all designed specifically for this weight class and riding style. Nothing is over or under-built, and that means lightweight, high performance"


“Thanks to an envelope-pushing powertrain with gobs of torque and a ridiculously light curb weight, the riding experience offered by the Kalk is genuinely unlike anything else out there”
