Slide over, Flexible Flyer. This Peak Toboggan from Sparkability.com in Germany, $370, will send your kid down the slopes in style. The frame is molded plywood, the seat nylon webbing. Sparkability also stocks three kinds of LikeABike (the training cycle with no pedals) and the Oko Trike from Italy, a spectacle of a thing with a padded saddle, extra-large wheels and a sunshade.
