A beamcycle is a motorcycle-type vehicle that appears in the world Gametron in the EMPATH: The Luckiest Smurf story "Inside The Game". They resemble futuristic motorcycles, except that they can emit beams of light from their rear ends, which solidify into walls that are dangerous to touch and can destroy a beamcycle and its rider if they run into them. It is also the name of the game in which players drive their beamcycles around an open arena to create light walls around their opponents in the hopes of boxing them in and causing them to crash their beamcycles into the light walls or the walls of the arena. Within the arena, beamcycles are only capable of making sharp 90-degree turns, while outside the arena they can make smoother turns.
The beamcycle is based on the light cycle from the Walt Disney film TRON and its sequel TRON: Legacy.
