They say the frame's the heart of a bicycle, but that's only partly true of the AMS Hybrid ONE44 C:62 Race 400X. Sure, we used our C:62® carbon to create a light, tough and agile frame. Then added a RockShox Psylo Gold air fork and Super Deluxe Select+ shock, to keep the Newmen Performance 30 wheels shod with Continental 2.4in Xynotal tyres glued to the trail. And powerful Sram Maven Base hydraulic disc brakes, plus slick and tough Sram Transmission 90 1x12 gears, give you all the stop and go you need. But the added secret sauce is Bosch's light but powerful SX drive with 400Wh battery (and optional 250Wh PowerMore range extender). With up to 60Nm of torque and a natural ride feel, it's the perfect accompaniment to our light, agile all-mountain trail-tamer.
