Cor, this just doesn't add up, for my case. Not the heaters, but the
difference in range between cold charging and warm charging.
Let's say I have about 2/3 the original battery capacity, which would be
16kWh. In warm weather, I'll guess I have a range of 50 miles, perhaps
60 if I go 40 mph

I have bikes with ev conversions I bought before the dedicated e bikes were
available, but hub motors. I don't use gears, I keep it in top gear. Can you
ride a centermotor bike only using top gear? Then you can do away with
derailleur?

I presume that there are 2011 with "winter package" and heaters in the pack.
They still have only a single HV connector on the front of the
battery, so the HV switching is done in the car.
I did find one inconsistency yesterday: I was taking a 2012 pack apart
and came across a total of 8 heaters,
Vextric had a throttle that reversed. Forward motion gave Regen. Very natural
feel. Lawrence Rhodes

So, even the 2011 has a modest heater, then ? I believe you. However,
how do you explain the vast difference between range (kWh during
charging) in winter 20F versus comfortable weather 70F ?
The heater doesn't heat the battery to 70F, it is
It's called a fixed gear bike. Move the gearing/transmission to the
hub/motor before the chain and it would work (a.k.a. a motorcycle...)
Fixed freewheels are easy, but I've never seen a variable locking one,
nor a "locking" derailleur.

I think David took a good crack at that:
The battery has higher resistance so the losses inside are a bit
higher and at freeway driving speed, the pack will hit minimum charge
level earlier as there is a larger voltage drop (limits are almost
always measured in voltage across a cell).
In addition,
Locking freewheel is easy, but the derailleur will never work with regen.
See for yourself what would happen. Grap the freewheel with a chainwhip, etc.
and hold it still while you try to back pedal. That's what's going to happen
when you try to regen.
My PGP public key:
I can't see anyway that could work. Perhaps with a fixie or an internal geared
hub, but not a derailure
