So I live in the US and I have seen a few videos proclaiming the virtues of Dutch style bikes including NoJustBike’s video. They all are saying that these bikes cannot be found in the US but couldn’t one just buy a step through frame and just add the missing features themselves such as a chain guard and parallel handle bars?
Short answer: yes.
Easy answer: you can just order one
I mean while some of the models have some of the features of Dutch Bikes, none of them have all or even most so they would still need to be customized.
