Luke says it's a suboptimal situation, but why the hell not. 1500w constant on each motor is good for 30-40mph.
16lb on the front wheel is good ballast.

Maybe a partial trade for my Hx3540?
Best of luck to ya up the hill.
Then Zombiess 2nd, if he shows.
The hub is filled to just below the axle with 400ml ATF.
The temperature sensor is fitted in the windings at the top, not in the oil pool.
The hall sensors are sitting at the bottom, in the oil pool.
The hub is a 7 turn MXUS running at 66v, 4.5kw peak power.
Ambient temperature during testing was 8 to 10 deg C
My regular 9 mile round trip takes in some sections of 20% gradient. I rode the same route at the same speeds (stopping mid point) with identical motors, exept that only one of them was oil cooled.
This route, when ridden briskly, burns about half of my 15AH battery capacity.
Max measured winding temp No oil ----> 140 C, with oil ------> 55C
Finish point winding temp .... No oil ----> 106 C, with oil ------> 38C

Even if you ride a dual pie setup it would be cool to ride together so we can frock pikes peak at the same time. But we shouldn't let our motors touch. I'm starting to sound like phillistine lol.
