It can be convenient to have a bike cargo trailer that converts into a trailer that is easily pushed around by hand. This can be useful for wheeling your gear down to the beach while leaving your bike parked. Or pushing your trailer through the grocery store. It is a useful mode if you have to push your trailer through an apartment building or to the office.
The Carry Freedom Large Y-Frame Trailer has been set up by the good folks at Carry Freedom as a walking trailer. This has been a somewhat custom modification that they’ve offered. They are working on offering the walking handle as a standard accessory. Some of their customers have used this setup for long distance walking trips.
