Science and Fun, Milwaukee

Like mobile Knights of the Round Table, bikers sit in a circle on Science and Fun’s seven-person conference bikes. One rider steers while all passengers pedal, powering bikes as they cruise through the city or serve as low-key parade floats. Groups with sufficient manpower for two bikes can turn open, paved spaces or Bucketworks’ indoor arena into bicycle basketball courts. Each bike constitutes a team, and both teams launch a barrage of foam balls at their opponent’s bike-mounted hoop during four-minute rounds in a game adaptable to all ages and pending NBA contracts. While advance bike reservations ensure a circular steed, Science and Fun happily reschedules or cancels reservations that coincide with inclement weather.
