FRONT HUB VS REAR HUB POWER and power settings

I have a Cyclotricity Revolver which has a front hub motor which I enjoy and I am curious about a few issues

1. Does a rear hub motor provide more power and produce better results for its power given its position

2. I ride my bike almost always in the lowest of the three power settings and I notice this doesnt help a great deal on hills except small ones but helps a lot for general starting and gaining momentum on flatter ground. I am deliberately trying to get a good workout so most of the time stay in lowest setting though if there is a dangerous junction or a hill start I put it briefly into max power

The bike is quite heavy ( I am not , I am less than 11 stone) at about 24/25 KG with its larger battery rack carriers and heavy D lock. I am wondering whether in reality on hills this might be harder work than a lightish hybrid without a motor. The other issue here is gearing. The revolver has 6 gears and a really big chainwheel which means unfavorable conditions for pedalling from starting or on hills

I wonder therefore whether the motor isn't responding well to the slowing down of the pedalling. I don't know how exactly it decides on power. Does it just push maximum power at any given setting with any amount of pedalling ? It is a cadence sensor and not the more sophisticated system on other bikes.

I have to say it is asking a lot for anything except the easier hills in the lowest setting.

As I think iw as advised here previously and have read elsewhere it might be good to get a smaller front chainset. Aside of this I am really enjoying the e bike feeling and its convenience. I think the Revolver is a good basic runaround and a good introduction.

Any advice much appreciated.

A 25kg electric bike on level one is more or less the same as a 9kg non-electric bike regarding pedal effort. Of course you can turn up your electric bike to level 5 for a steep hill.

It's nothing to change gearing. The Revolver has a crappy freewheel with 14T top gear. You can get a DNP freewheel with 11T top gear from Aliexpress, which means that you can get a smaller chainwheel to reduce the gearing in the low gears whilst still have a comfortable cadence when going fast.

A rear motor is quieter, gives better steering and has better traction on hills. Not all motors are the same, you get small/big, DD/geared, different speeds and different voltages. If all those parameters are the same between a front and a back, they'll both give the same power and torque.
