Take your tykes in tow with the InSTEP(r) Sierra(tm) bike trailer. The lightweight steel trailer is designed with a coupler that attaches to the rear hub of nearly any bicycle, and the cabin holds two children (up to 100 lbs total weight) securely within a five-point harness, beneath a rain shield. For additional versatility, the trailer easily converts to a stroller with a padded push bar and swivel wheel.
