Okay, figured out a trick in the process that helped a ton, and I now have Code RSC on the bike:
Pushing the hose rear to front, when you put it in the frame near the motor it wants to get pushed into the back of the housing where the female battery connection sits. There's two small bolts...
Anyone here tackled rear brake swap? I have an E1, and am throwing on some Code RSC, but just got to the point where I realize the hose is routed to come in behind a portion of the motor. When I push it in it just hangs up behind where the battery plugs in. Would really love to not have to...
