I have a Kia Sorento and tow a Bessacarr Cameo. I have recently acquired a bike for myself (20kg) and an electric bike for my wife (38kg with battery). I want to take these on holiday and need to secure the bikes on my vehicle or in the van. I need to manage them on my own as my wife is disabled. Any advice on simple, safe and relatively inexpensive way to transport them would be welcome.
