It's difficult not to come across as an arse sometimes, but stirring up discussions of why this or that is better sometimes brings up views and thoughts that we might not have considered or thought about. I'm not here to fall out with anyone, and I'm absolutely happy to have my assumptions shown to be wrong because I've read (and believed) numbers.
What I KNOW is:- I've got a Giant Trance zero and I'm really sick of it breaking, so I'm looking for a different bike.
I ride it mostly in Eco, and even then I sometimes reduce the power in Eco to 50% (the lowest available) with the app because even Eco does more that I feel is needed (100% of rider torque, apparently) and I sometimes want more range, because when you run out of battery with it it's like trying to ride through a tar pit, it's awful.
I was looking to buy a more modern analogue bike than the one I've just given away that I've had for 20 years, but a lighter e-bike with minimal drag could serve both purposes, which is particularly why I like the IDEA of the Fazua and thus why I'm driving 2hrs 40 to Kielder and back again tomorrow so I can try one for myself. If I like it great, if I don't I'll see if I can get a ride on an SL.
The reason that I FEEL that the SLs output may be too low is because we live in a very hilly area and sometimes that bit of extra oomph is handy, and watching the various tests it does look to be lacking.
That said, the tests themselves are often lacking.
