pulled apart my "infront of the seat pack" which contained 3s batteries to pull one out and added in series to the 12s just for the mid drive.
charged both battery systems to 4v a cell to get a feeling for what I might get into.
15s1p 60v 25 amp mid drive
12s2p 48v hub 65 amps
on road
I only got the mid up to 31kmh thats just a few km more than at 12s hot off. I don't quite understand... expecting more but I guess they is more of 14s hot off the charge voltage.
Anyway it might be that I haven't lubed the drive train but once the motor winds out at topspeed in the fasted fear grinding phase kicks and then gets passed. Before I think I just fell under that phase. Maybe there's some weird timing of when the links are bending and just vibrating in their bend poorly in some weird frequency. weird.
At first I wasn't impressed. The delay for throttle off felt much worse, a poor gear change worse than before too and the torque needed getting used to...
a bit of sunlight left I need to test the granny gear off road straight up the mountain 30% slope...
57v mid
shifter cable played up gear wouldn't stay in granny, so I had to pull the twist shift hard to hold it in that gear but it fell off the granny under load and you guessed it!
BROKE THE CHAIN
it was on the steepest section too. Anyway stuck it in my pocket and could have taken the straight route home but said nope I got a hub and enjoyed a longer route home.
First experience of riding without a chain in my life. Takes getting used to because we balance the bike with the tension we put on the pedals. Also, gave me a good experience of how it felt to ride a motorbike, with only the throttle doing all the power stuff. I like it and felt kind of like throwing the bike around more.
So the questions now are:
- if the chain had been lubed
- if I had been at lower voltage
- if the shifting cable had been tightened
would this have happened? and what combination of these?
Should I just stay away from the higher voltage....
Anyway took the broken link out temporarily and will try the same section again today. Have ordered for $66 au of ebay

no idea how the link works, if my chain tool will work with it.
