Oh, I’m not trying to imply that. I ride a traditional bike myself in an incredibly hilly area, and it can absolutely be done (though it really sucks sometimes). I’m just noting the reality that there’s less effort involved in flat cycling than in hilly cycling and the Netherlands is famously flat.

People in really hilly areas can also get e-bikes, which would still be a huge improvement over driving, but wouldn’t bring us down to the transportation emissions of the Netherlands.
