Last year, a new stand-on electric motorcycle made its debut, defying categorization. Performance Concepts Inc.’s 2011 MXB Shocker motocrossboard was a hand-controlled two-wheel electric vehicle that looked like a cross between a snowboard and a dirt bike. There was such widespread interest in the Shocker that PCI CEO Andy Keel decided to work on the vehicle further before releasing it for orders. The results have been awesome: 4 new 2012 Shocker models are now available for pre-order, and they’re lighter and less expensive than the first version. Even the largest motorcycle museum in the world, the Barber Vintage Motorsports Museum in Alabama, is getting excited about this unique, green vehicle, and will be displaying the original Shocker prototype there soon, an honor which Keel says left him speechless. So, how does this thing work?
