Indeed as someone who straddles two places of living I can attest to that. When living in a relatively flat city I’m cycling everywhere (on e-bike until it was stolen, then on cheap muscle bike thereafter). My other place of living is extremely hilly. Used a muscle bike and quickly said “fuck this, I’m done”. Just like the article said about hills on the trails. And since I cannot justify the cost of an e-bike in that particular place/situation, I do not cycle at all when living there. But if an e-bike had been cost effective I would be getting more exercise in that area.
