I’ve been noticing this Burley Solo Bike Child Trailer locked up in front of a Flagstaff Preschool on my way into work. Seems like a great way to bring your child to school and then have your trailer where you need it when you pick your kid up after work. Looking at this example, I do have a few recommendations. I would recommend that the Ulock run past part of the trailer’s aluminum frame rather than the plastic wheel guards. A 4 foot cable would add some security running it through the wheels and frame to the lock. A Burley storage cover would also protect the trailer from the elements.
