The invention was designed to provide a solid, level hang bar utilizing the bicycle's seat post, seat post tube or frame itself which is level adjustable on the bicycle. The rake or angle of the seat post and seat post tube varies and the Bicycle Leveler is adjustable to allow a safe and level carry on a vehicle. The Bicycle Leveler is installed on the bicycle for safe transport and the Level Hang Bar is uniquely removable without tools for safe riding of the bicycle. No other design mounts solidly to the bicycle nor does it have removable level bar feature. The design represents a new methodology for safety in bicycle transport on traditional hang racks.
