They say the frame's the heart of a bicycle, but that's only partly true of the AMS Hybrid ONE44 C:68X Race 400X. Sure, we used our premium C:68X® carbon to create our lightest e-mtb frame yet. Then added a RockShox Psylo Gold air fork and Deluxe Select+ shock, to keep the Newmen Performance 30 wheels shod with Maxxis Dissector 2.4in tyres glued to the trail. And powerful Shimano Deore hydraulic disc brakes, plus reliable XT 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 55Nm of torque and a natural ride feel, it's the perfect accompaniment to our light, agile all mountain trail-tamer.
