While Weehoo’s beloved iGo Pro trailer is a wonderful way to bring your kid along for the ride, what happens when more show up? When it’s time to double-down on the fun, Weehoo’s iGo Two Bike Trailer rolls up. Longer than the Pro version by 11 inches, the Two accommodates an extra seat for a second child aboard. The Two is otherwise extremely similar to the shorter Pro. It’s made from a lightweight steel frame, onto which the alloy seats are mounted. The modular platform means that the second seat can be swapped out for the company’s Cargo Basket or other add-ons for greater utility. It rolls on a durable 20-inch wheel with a puncture-resistant tire, secured to the frame with a familiar 15mm axle nut, so all you need is a wrench to remove it if necessary for storage or flat repair. That wheel is linked to the iGo’s crankset, which allows your child to pedal along and put in some of the effort, too, while the chain is fully enclosed to prevent getting fingers nabbed or getting grease all over shoes and pants. The trailer attaches simply and easily to the pulling bike’s seatpost via one of five different included seatpost diameter bushings. The iGo Two Bike Trailer comes in one color and weighs approximately 44 pounds. The seat fabrics are removable from their alloy frames for hand washing (machine washing is not recommended). The front seat is for the larger of the two children. The combined child weight limit for the trailer is 100 pounds.
