The Bisikle set is a real treasure. It has 57 pieces and over 13 ft of track. You can decide the difficulty, add obstacles and create the most challenging races! BISIKLE is an exciting experience that will quickly take over the traditional board games. The players have to compete on a crazy track in order to win a bicycle race. No cards or electrical devices are involved. The whole concept is in the ZBall, a marble with a unique internal mechanism. It is very easy to control. Basically, the goal of the game is to flick your way to the finish line as fast as possible. The challenge is to control the effects of the ZBall and pass as fast as possible through all the obstacles (slopes, fences, jumps, mouseholes, etc.). Bisikle is the first of many ZBall games and was published in 2009 (September) in the USA. A track has to be built and looks like the slot-race ones.
