@bikepedantic I transported a trombone and trombonist on a tandem a few times but I never got him to play while I pedaled. What a missed opportunity! Although, I think bakfiets have some clear advantages with the front carry position with trombones. Maybe I can convince my 13yo neighbor to ride on the back of the GSD playing her trumpet. My kid plays the baritone sax and that's a big replacement value if something goes wrong.
