I used to pick up my kids from school using a tandem and a pedal trailer behind it. As they outgrew the pedal trailers, I was trying to figure a way to allow me to pick them up from school on the bike when Mom drops them off in the car.
I picked up this baby trailer off the side of the road, added a little bit of pine, and I cut up an existing bike rack. Overall, it’s a little bit heavier than I would like, but this is more of proof of concept… I don’t do anything crazy with it, and the kids school is only about a half mile away, but it works pretty well.
if I find it works well in the long run, I might weld myself up something with half inch tube, as opposed to the solid rod that the bike rack uses. Are used lumber as the base as I want to be able to haul stuff with it when the bike rack is not bolted to it.
