My contribution is 100W in this case, exactly the same contribution I will do on regular bike, but riding way way slower. I am not gaining/loosing any noticeable amount of watts when I switch bikes.
That is what
@mschwett said: A human body is limited by its own performance, and it does not depend on being assisted or unassisted. Only the word "contribution" is tricky here. Your contribution is the same but the contribution %
into the ride is 100% on a traditional bike while it is (far) less than 100% on an e-bike. Meaning, your kcal burnt only depend on the pedalling time. You can only get more workout if you are pedalling really hard and/or your ride takes considerable number of pedalling hours
This is the point. The torque sensor does the scaling of your effort, but won't work instead of you. So you can build your fitness on ebike as good as on regular bike. And be faster / ride further off course!
Yes you can. There's even an interesting phenomenon: if I ride in Turbo mode, I'm trying to squeeze as much speed out of the e-bike as possible, so I work harder! Only such a ride cannot last for long.
The weak point about e-bikes in their workout role is they make you lazy
Rough riding surface (gravel, dirt), headwind or hills only require you to increase the assistance to keep at the speed. Try to ride your e-bike unassisted up an overpass and you will realise how hard it is... Whenever you need to face additional resistances on a traditional bike, you are trying harder to stay at a reasonable speed...
Let me convert it to kg for better understanding. You weight is around 70 kg.
- A full power e-bike, 26 kg. Total system weight 70 + 26 = 96 kg.
- An ultralightweight road bike, 6.5 kg. Total system weight is 76.5 kg.
The Aethos + you total weight is around 80% of the Vado + you. You actually gain 20% for climbs and acceleration riding the Aethos compared to something like a Vado. In my case (96 kg in full cycling clothes and a helmet), I would only gain 16% between the Vado and the Aethos.
Yes, riding an ultralightweight bike is a lot of fun but if we compare an e-bike with a lightweight traditional bicycle, the gain for me in favour of the trad bike would be:
- Able to lift and carry the bicycle
- Good handling in rough terrain
- No range anxiety
- Treated as a competing cyclist.
(I know, I'm repeating myself!)
Otherwise, a traditional lightweight bike can offer me nothing an e-bike could not compensate with its motor
