Carefully check the maximum weight allowance for the car roof, roofbars / rails and the actual bike rack. This can also be physically hard to do, especially with heavier Ebikes, although removing the battery can save a few kilo's. Heavy duty rear mount racks or tow-bar hitch mount racks would be a safer and more manageable option.

Most people taking their bikes abroad would use a padded bike bag. These special bags are well padded and offer substantial protection for your bike. Most bike bags fit most types of bikes. Check online video's for bike bag packing tips to ensure you get the best protection for your bike.

Features such as a solid base, towing wheels, extra handles and secure internal pockets for pedals etc, all add practicality and easy usability for a bike bag. Whilst offering lots of padded protection, bike bags also need to be relatively light so they don't eat into your baggage allowance too much. Check user reviews for real life bike bag experiences.  

There are a few options for driving with your bike. A bike roof rack or boot rack keeps your bike securely outside the car, and so doesn't use up space in your car or boot. Racks are also the best option if your bike is dirty after your ride. With bigger hatch-back, SUV and estate cars, it might be possible to take your bike inside the car with wheels out, if seats and interior are well protected. However, this will eat into space in your car and no matter how careful you are, it is very easy to get oily / dirty marks on car interiors.
