For an out of shape cyclist, driving 20 km can be a challenge. I remember in 2015, when Marek and I went on a trip. Back then, we were still riding ordinary bikes, without electric assistance. We were supposed to drive about 30 km. For me, an amateur cyclist, it was easy, and for Marek it was a test of fitness. Well, we finally did 50 km and Marek was very tired😜.
Today, on an ebike, we even 100 km. Our butts hurts, but the condition is no problem.
