This would have to be one of the best bike racks money can buy as it addresses the problem of being in the way when not being used. So at night there is no way you will walk into it and shin your knees! It is constructed of aluminium and bolts directly onto the rear of the motorhome thereby avoiding the stress problems associated with attaching to the rear bumper or spare tyre bracket. The rack shown holds four bikes but smaller models are readily available. We particularly like the clamping system used. Even though it is plastic it is ideal for expensive bikes as it doesn't scratch. Security is excellent and the bikes are locked on using keys. More info from Coast to Coast RV - expect to pay from $300.00 upwards depending on model. Good dimensional drawings are on this page - be warned - there are lots of choices!
