Kids' bikes are learning to grow as quickly as children. Designs like the Grow bike and B'kid expand in size to keep up with the fast-growing tyke, and the Wishbone bike keeps right on growing from pedal-free balance bike to pedal bike. The new Leg&Go bike does all that and even transforms to keep the ride going indoors and out in the snow.
Over the years, various manufacturers and inventors have tried different ways of putting "two wheels" to the snow. The rise of fat-tired mountain bikes, not to mention extreme Antarctic fat trikes, has been the biggest news in this area, but we've also seen recreational equipment like the KTrak and BikeBoards. A group of mechanical engineering students at Quebec's University of Sherbrooke is developing a new solution that aims for a smoother downhill ride by combining elements of existing winter bikes.
