We have purchased 2 Cube Town Hybrid Pro 500 e.bikes which we love, so easy to cycle. Despite the advice they should be carried inside a vehicle (which we hadn't realised when we bought them), we have a small caravan and we carry our cycles on a Witter flange attached tow ball. This will take 60kg in weight so will carry the 2 e.bikes. However finding a suitable false crossbar is a nightmare. We have identified one on Amazon US that might be suitable, but decided to check out this forum to see if anybody else has faced this problem and if there is a solution. Any help would be appreciated.
