Trailers for Lammys and P-Series

Maxi-Trailers makes uni-wheeled scooter trailers out of old scoots. They also make a PAV replica. They open from the top and feature locks for security. In what I think is a genius touch, they utilize center stands to keep them upright when not attached to your bike.
Plus, they are right purty!
The prices are on par with what you'd pay for a restored or good condition PAV, i.e. around $1200.
