Tryed today on Giant Reign E+1!
Never tried yamaha I can only compare it with specialized Brose, I found it a little noisier but let's be clear the noise is not of various gears or clattering, only that squeak of electric motors, that clutch they make when they are under stress, so I would say...
I wrote to him on FB and he didn't tell me if he will do a special review, but he told me to ask him everything I wanted, he's really kind, I'll give you questions and answers:
Also I tell you that I JUST TRY IT :p
