little update:

using the bike for 2 weeks daily now..

last week:
done 360km with ~3600meters of hight

when going to work each day (~60km with 600hm)

meanwhile running with 36V-43V and 7Ah in sum
(using 3 batteries,
1 Lithium polymere (made from 3 rc-lipolies of different brands connected in sereis to reach 36V)
1 Lithium mangan (36V BOSCH)
and 1 13s1p Fepo4 (42,9V))


i use the motor mainly for going up the hills..
on flat terrain 100% of power comes from my legs..
(so most times iam running without motorpower, and only on the hills i use the motor)

i reach - depending on my daily fitness - 28-29km/h average speed at the 60km trip


here my batterie-setup so far...
will make it more beautiful after the summer.. now no time for that

it for now has to work for the daily 60km trip

iam meanwhile also running at the rear an Schwalbe big-apple (the 26" 2,35" (60er))
i love this tires !
absolute great and perfect for an electric bike in my eyes

(was today going on some offroad-trails (wood, gravel),
and it was running so smooth, lovely !)

my meanwhile older, not so fit dog also loves the bike ;)

Hey, well done,

That is impressive range on those size batteries - are you recharging them at work?

That is an impressive average speed too.

no.. i don´t recharge them at work..

so ~60km from ~7Ah and 36V (43V)

as said, i use the motor only up-hill..

when i need about 2 hourse for the trip, i have 30min of full-throttle motorpower (14A motor-current limit, 7Ah battery-capacity = 30min)

so 3/4 of time is my leg-power alone and 1/4 is with motorpower at the hills
works great..

hey..
for average speed:

today i was - first time - with my trailer and RC-plane at the flying field..

14km in one direction
+ 14km back home
+ 6km done by 3 people who realy wanted to test the electric bike (and all were very euphoric after a testrun)

so: not that far, i was able to spend more energy per kilometer..

average speed: (including a 120m high hill): 32km/h
INCLUDING the trailer !
with not that much air in all 3 tires..

this one-wheel-trailer is great..
even at 62km/h no problem at all with it..

yeah-ha:
2 Month driving the bike (only short trips at the evening) ->
broken the 1000km mark !

in former times i was not driving that much in a whole year!

iam also happy that i have safed the money and didn´t took the rear-wheel version..
the all-wheel-drive (2WD) is usefull when going offroad
