Toyota revealed its i-Road concept, a three-wheeled all-electric motorcycle of sorts that seats two. The unique design is only 33 inches wide, which would make it tops in buzzing in through and around traffic. An Active Lean system tilts the i-Road through corners like a motorbike, while the cabin (which seats two in a tandem layout) is fully enclosed. Maximum range is about 30 miles.
