One of the lowest priced, ASTM-certified child trailers on the market today, the lightweight, bike-only Burley Bee Child Trailer keeps the little ones content while you buzz around the neighborhood. The Burley Bee has been updated for 2016 with a Flex Connector that allows the bike to lay flat while the trailer remains upright. Also new: tinted side and rear windows with integrated UPF 30 for sun protection, a lot more storage space, and side battens that create a barrier between the wheels and your child. It weighs only 20.5lbs and protects up to two passengers with its full internal roll cage, heat-treated aluminum frame and 5-point safety harness. Convenient rear tailgate provides easy access to cargo, 20" quick-release wheels roll smoothly and compact folding design flattens the trailer for storage or transport.
