So in Costa Rica last year, in super hot climate, and after a 90 min gym session, I tried to ride an e-bike up a giant hill and failed. I'm not sure if it was because the bike was too heavy, or I was so tired. Looking for anyone with experience riding one. I'm going to a beach town this weekend in Spain and they have a bike tour and I'm looking to do an e-bike tour one of the days, but don't want to fail again.
