Ciao Budcher, well observed. Thule itself mentions a maximum weight of 15kg per bike. I have been using this platform for 2 weeks. It works sensationally and is stable enough for my two fullys (each a little under 13kg). But I wouldn't want to use the system for an e-bike weighing over 20kg... If you don't have a trailer hitch, transporting e-bikes becomes difficult. I also searched for a long time and didn't find a suitable solution for my station wagon. I didn't find anything for the rear and you don't really want to lift bikes with 25kg onto the roof... Consequence: "Electricity in your trousers" and pedal yourself... ;-)
