But what are "full power e-bikes" exactly ?
The "full power" e-bike is the heavy one, with the peak motor power from 430 W (leg power amplification 2.8x) to 565 W (leg power amplification 4.1x). Of course all EU motors are 250 W nominal (the continuous motor power). Specialized Como, Vado, Tero, Tero X, Levo, Kenevo are all full power e-bikes. All Giant e-bikes I know of are "full power".
There is a new class of e-bikes known as "super lightweight". Specialized e-bikes of this type are marked by
SL. The "super lightweight" motors of different makes (used by different manufacturers) are 240-320 W peak power and the batteries are intentionally small, such as 250-320 Wh depending on the brand. Super lightweight e-bikes are not for everyone, as these require a solid pedalling to perform. By the way, Specialized Como SL is about the heaviest Specialized SL e-bike.
The seller told me they were pretty much identical, except that the Vado can do a bit more off-roading.
Not at all! Como is a classical city e-bike. It is a "comfort" e-bike, easy to get on and off, with a very relaxed riding position. Vado has a quite sporty character, as the main purpose here is the commute. The riding position on Vado is "moderate", that is, you need to lean forward quite a bit. For instance, Como is equipped with a very wide saddle while Vado has the sporty, a way narrower one. Yes, Vado is more appropriate to do some easy forest rides than the Como is but it still doesn't not eliminate the Como from some recreational use.
I think the motor are quite the same between the models.
The 2.0E, 2.0, and 2.2 motors are shared between the models. Even the weakest 2.0E motor is pretty strong, and I demo rode an e-bike equipped with such a motor. I have never missed the power but I admit I tested the e-bike on the flats.
I will get a Giant to start with. There's not much choice, but it should be 50nm with a belt.
What model?
