In kid world, a tricycle is to a motorcycle as the Angeles Silver Rider Supercycle is to a chopper. With a profile a Big Wheels, the low-riding Supercycle combines the safety with a cool, minimalist design. The chrome-finished steel frame sturdily bears the weight for 4 to 6 year olds, while the steering limiter helps keep kids from careening across sidewalks. Solid rubber wheels probably will rob riders of the delightful whooshing sound old-school plastic Big Wheels would make before they gained traction (remember that?), but they are the more durable, safer option. Like other Angeles trikes, the design avoids pinch points, as well as exposed rough edges or hardware. At $169.95, the Supercycle is a bigger investment than its plastic counterpart, but it comes with self-lubricating bearings and a 5-year unconditional guarantee.
