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.<br><br><strong>Frame description</strong><br />The AMS Hybrid ONE44 C:62 frame begins with our time-proven C:62 carbon, crafted into a structure that's light enough for a lively ride feel but plenty tough enough for the trails. The 400Wh battery is incorporated into the down tube, as close to the lightweight Bosch SX motor as possible to improve handling, and the frame is PowerMore-ready for a 250Wh range boost with the optional battery pack. Internal Cable Routing complements the frame's sleek silhouette and there's a lightweight Direct Mount chain guide. With a UDH gear hanger and angle adjustable headset so you can tweak the handling to suit your riding style, it's got everything you need for fast-paced trail riding.
