Back on the topic.
@MMC,
@minigrrl,
@Dallant: I hope we all mean "low powered mid-drive electrically assisted bicycle" when we say "e-bike", right? I think the biggest misconception about e-bikes/physical exercise is comparing the effort needed to ride over a defined route segment, that is, comparing the effort for the same
distance and the same hills for e-bike and a regular bicycle. No doubt: with the same distance and elevation gain you'll be less tired on the e-bike. What most of people overlook is comparing the effort for the same
ride time. Whatever you add to your ride in the form of electrical power manifests in far longer distance ridden and more elevation gained over
the same ride time. (Effort is the same).
Examples from my own practice:
- My longest traditional bike ride (I was healthy at that time): 73 km/120 m elevation gain in 4.3 hours
- A typical e-bike ride with my brother: 101 km/500 m elevation gain in 4.0 hours
- My longest e-bike ride: 122.7 km/500 m elevation gain in 5 hours.
(The results for e-bike rides are for a man suffering from arteriosclerosis who can hardly walk; that's me).
- An experienced traditional cyclist @Jerzy Bańkowski : 121 km/140 m elevation gain in 6 hours 59 minutes.
So my friend needed two hours more to make 75 miles while riding a traditional bike. Of course, he got more workout on his ride because he had been riding for two hours more!
There is a factor making us think we get less exercise on the e-bike: limited battery range. An e-biker rides out, completes their 40 km ride in a short time (one-and-half hour?) and thinks his/her ride was effortless. Of course it was. So, the e-biker dramatically reduces the assistance (whenever doable) or rides without assistance or buys a Specialized SL e-bike "to get more workout". However, reducing assistance or switching the power off only means you get more tired
over the same distance. While the whole idea is to ride farther (or, faster) and more frequently... Dammit! If I wanted to pedal unassisted, I would have bought Giant Trance (non-E) for half of the money!
Still disagree? If yes, you're giving e-bike haters solid ammunition
P.S. I was on a ride together with a female friend of mine on last Sunday. She was very proud of the fact she pedalled for 58 km off-road "without any assistance!" How could I say to her I would make as many as 88 km if I rode alone? But I had to reduce the assistance in my Giant Trance E+ to 75% Eco and spin at high cadence at 8 km/h at times to ride together with her and not abuse the fact my bike had the motor...
