[quote="Ken TaylorYour information on the BH Emotion Neo Range motors was useful. They are pretty and generating some interest in Australia at the moment. See http://forums.whirlpool.net.au/forum-re ... &p=18#r347
. I like the look of the Neo Race http://www.dolomitiebikes.com.au/bh-emo ... s/neo-race
Yes, they're nice bikes and very good climbers, but tell them on that forum not to believe that it has any Significant regen.
We figured out from some tests that The Emotion Neo series doesn't have any regen because it has a free-wheel in the hub. We spun the wheel and no regen happened, which is not surprising because the motor didn't turn. I'm sure that the bike has a controller and panel for regen, probably borrowed or developed from a DD motored bike, but it can't give anything significant. When you cut the motor, it takes a small time to slow down even though the free-wheel disengages it from the wheel, so you get a miniscule amount of regen each time you shut the throttle, but it's not enough to be of any use.
On a 35 mile journey, I got 0.05% regen - equivalent to 0.01aH
If your clutch sticks (not uncommon on a BPM) of course you'll get much more significant regen, but then you have a DD motor.
