Do I have to remove the Hauler swivel wheels to tow with the Bike Connector Kit?Updated 2 hours ago

Yes, the swivel wheels come off for bike mode. Put them in the SmartBin and they travel with you. When you arrive, refit them and the Hauler works exactly as it did before, so you can cover the last stretch on foot. You can fit the standard swivel wheels, or the Beach or High Performance Wheel Kit if the ground calls for them. The mounting plate that attaches under Hauler does not need to be removed to refit the swivels—once you set it you can forget it.
