The other day he did 2 times 14 km with his mother to and from her work, today he and I did 31 km, using 4200 mAh from the 5000 mAh LiPo pack.
End idle voltage was between 3.65 and 3.71 per cell.

I bet he had a grin from ear to ear.
That makes for a light weight assist with only needing one battery.

I tested the BBS01 18A 350W today.
You have to push a bit on the pedals, no longer just rotating the cranks.
Could have sworn that there is a 'click' when I start pushing on the pedal and a 'click' when I stop pedalling.
It seems like some kind of pedal sensor, it cuts the power immediately when I stop pedalling.
The motor is dead quiet, fanstastically better than my 18 month old 15A BBS01.

not. It does not feel as powerful as the BPM motor though.

The '36V 350W' is printed on the underside of the motor.
You need to turn the bike upside down to see it.
you have to push on the pedals a bit, making it very close to riding a Bosch bike.
There are quite a few improvements in comparision to my 18 month old motor. Better display, more setting options, the bottom bracket nut is now covered by a very pretty cap. The most noticeable is its quietness. The new motor is so quiet!

there is a difference.
A manufacturer can slap their EN15194 sticker over it, and we can't.
That's why I've been posting about unfairness when more powerful motors like the BPM and Impulse and Bosch Performance are street legal and the 18A BBS01 is not.

Why did you ask the question if you are not interested in knowing the answer?:rolleyes:
It was rhetorical essentially. But you choose to answer another question which I didn't ask, and one which some here ride as a hobby horse. Anyone who has been on this forum for even a couple of days could hardly fail to have seen the endless pointless wrangles over that.

Well you can - there was a guy selling them on ebay a few weeks back ;-)

Oh, and the 350w marking on the BBS units are only stickers - it's amazing how easily they fall off ;-)
