Maximizing fun with its front passenger pedals and open cockpit design, the Weehoo iGo Two Bike Trailer alleviates boredom and mid ride meltdowns when you're cruising around town and exploring backwoods paths. It fits kids from two to nine years old and tows up to 80 pounds of total weight. Buckled straps and grippy handles provide security and safety, with the front passenger enjoying the fun sensation of pedaling with rotating strap pedals. The rear passenger gets a solid, strap down platform for safety and comfort on longer rides. The iGo Two Bike Trailer's well balanced design promotes easy towing behind your bike, attaching to cylindrical seatposts ranging from 25. 1mm to 31. 9mm. Plus, its redesigned seat offers tool free adjustments when you're hauling different sized kids.
