Our tried and true longtail U-Tubes are an ultra-useful addition to any longtail Xtracycle cargo bike. They support cargo, act as a footrest, and make it possible to tow one or more adult or kid bikes. Now upgraded to attach with push-pins making them easy to install when you need them and remove when you don’t. Price includes a set of two – one U-Tube for each side.

The U-Tubes are not compatible with any RFA model or any non-Xtracycle brand cargo bike.
