The bicycle is worth it if you need something that opens and closes easily. I tried it 2-3 times at home before going outside and it was fine. If you don't need a folding bike, I can't say it's worth the money. It's not particularly sturdy and already after a month, it seems to stick a little when opening, the handles also sometimes stick on the button. The difference in models is the storage bag (in my opinion necessary) and the transport bag that we needed due to frequent trips. The price difference for the bag, which is nothing special, seems outrageous to me. When the pedals hit the wheel due to the child's height, unfortunately the bike is difficult to steer for the parent as the wheels turn very easily as the child plays with the pedals, resulting in wobbling on the road and requiring both hands from the parent. Also, the thick handles do not allow for the placement of a bell, which children usually like a lot. The only thing that is worth it is that it folds easily and seems to have good wheels
