Bikes

Rockwell's newest picture book shows tigers in a wide variety of locales riding an even greater variety of bikes. Little cubs on tricycles soon give way to bigger ones on two-wheelers and parents riding bikes with baby seats. Unicycles, tandems, high-speed racers and slower, clumsier delivery bikes are all introduced. Even the more unusual types join the collection: the stationary exercise bike, a trick motorcycle, a motor scooter, trail bikes and mopeds. The colorful illustrations are humorous and will continue to please with each rereading. Ages 36. (April)
