New 2019 version with added locks and straps for wheels. BNB makes these uniquely for NZ only, being towball mounted. It holds 2 e-bikes including batteries, to a maximum of 60KG. The platform can tilt downwards by releasing a lever, making is easy for you to wheel the bikes onto the carrier. The central uprights bar has 2 sliders on it, which slide down on the bike to hold it firmly. These hold down brackets also have locks, removing the need for a seperate lock. The upright folds down for easy storage.
