Looking for a viable solution I found the M-Wave Bicycle suitcases on Amazon. Nice and easy to attach and secure fix in a few minutes on the luggage rack. Very useful, the two side flaps, in addition to the lockable lock available.
No more rattling while driving and the firmly screwed with the Porter bicycle case can never fly away. There is plenty of space for the bike helmet or other useful things, such as clothing, food and beverages; but also present in my e-bike, for a second battery or charger.
Very useful for my decision to buy this bike suitcase were also the existing customer reviews for the M-Wave, with whom I now have a lot of fun for me.
