hey CptPalmer, my first thought was: sell the ST1 for decent money and start from scratch.CptPalmer said:I currently own a ST1 and I need more speed I was looking at swapping out the motor and more or less gutting out all the wiring and replace everything and adding a throttle, new controller likely to be placed in the down tube and add a CA with a triangle bag with homemade Samsung battery pack. I am really new to the DIY side of all this and I interested in all suggestions.
my next thought was, the stromer's are well built ebikes, so you get a lot that you won't get in another doner bike, so it's a tough call.
one big issue will be fitting another motor in those drop outs: (from p3)

but do you see that? the freewheel side is in tight and the wheel's more or less centered, but the disc is over an inch off, and i'll need a million washers:
my rule maxes out at 153 and is at least 5mm short:
once you fit another motor tho, you'll also need torque arms. they're no doubt better than a standard alum frame, but the one side has a cut for the torque sensor which will likely reduce its strength:
depending on much faster you wanted to go, my suggestion would be to rewire the existing motor like i did. i'd wanted to drill holes in it to vent, but the way it's press fitted, i'd worry about any holes weakening it tho.
so i don't know. what'd you decide to do?
