yes, it seems a popular entry level model! I waited till they came out at the supermarket
with a bike with Lithium. At that point no excuse, needed to try and verify the performance.
It has 3 power assist levels : min (80 W), medium (120 W), max (200 W) + 6 kmh speed limit (10 W).
Speed reached at different assist with no pedal is 17, 21, 25 kmh.
full charge battery is 29,2 V, they are 7s5p and they are LiMn, so the battery gauge is a bit off:
75% battery is really meaning 40% and the other 3 leds are like 30% , 20%, 10%.
Practically, the 25V x 11Ah are enough for roughly 40 Km at great speed
and very light pedaling or almost none ... so 6 - 7 Wh/km, not bad
with max assist only it is going 30 Km per charge, using medium and max with light
pedaling just to pretend to do some exercise it is going for at least 50 Km ...
I probably will add some additional capacity to reach 15 Ah ....
I will add some Zippy Lipo liying around ...
that would make respectively 45 and 75 Km per charge with top up time of 8 hours.
At that point it will be as good as possible for an entry level 200 Watter
So far so good, no broken parts, motor slightly less noisier than at the beginning.
It mounted fine also a rear kid sit, after phisical annihilation of the driver sit bracket and screw.
.. 500 Km .... by car it would be around 40 euros of gas!
it seems that at 5000 Km the bike is paid in full via saved gas cost, since I charge with solar ...
