Having already successfully incorporated its patented Cantilevered Independent Dynamic Linkless Indispension (CDLI) into lithium-powered scooters and wheelchairs, Patmont Motor Werks (PMW) has now upsized their suspension system and installed it into a motocross prototype. Still in the early stages of development, the “Shocker” is intended to be a tri-sport machine (street, dirt, and freestyle) that relies on electric power, allowing it to be operated within communities without worries about emissions or noise by-laws.
Weighing in at a rather trim 198 lbs, the bike holds 2.3 kWh of lithium polymer batteries and runs at 78 volts nominal at 250 amps continuous. The sealed liquid-cooled DC brushless dual axial gap motor (ok, breathe) is 94 percent efficient at 3000 rpms with throttle-controlled regeneration abilities that can extend your riding time. Speaking of the throttles, this one is wireless so freestylers can do bar spins and tail whips to their hearts content. Besides the impressive running gear, the most interesting part of this motorbike is the way the frame is suspended. The unique design is said to allow for 13.5 inches of travel front and rear and give it dynamic anti-dive properties under braking. If everything works out as planned, a production model will get its own purpose-built aluminum frame and, like all PMW products, will be built at their facility in Nevada. Hit the jump for some footage of this promising prototype putting down its power to the pavement.
