The Burley Cub X Bike Trailer is so versatile. How versatile is it Well, not only does it convert from a bike trailer to a stroller for on- and off-road adventures, but its two child seats can be removed or reclined, offering comfort for whoever's in tow. This 55-liter trailer features a durable plastic base rather than a soft bottom, ensuring our cargo stays secure whether we're grabbing groceries from the market or taking the tots for a ride. The shaded fabric shell provides water resistance and UV protection, so the kiddos are comfortable and covered no matter the weather.
