Have you done a Rear Hub and Mid-Drive Hybrid drive system ?

On a diferent note , Is a Befang BBS02B 500 watt motor the same as a BBS02B 750 Watt motor ?
Just different settings for higher amps ? or is there different hard components inside the motor ?

You have to use a 750 watt controller otherwise it's the same motor.

What I am looking for more than a few points of efficiency is a way to save wear and tear on a mid-drive.
After using both rear hub motors and a Befang BBS02 and a BBSHD mid-drive I want to
get the most amount of years of life of my/a
BBS02 and BBSHD , as well as the most years and miles out of my drive train. I only ( Need ) , the mid-drives for going up the steep hills and mountains around where I live. So on one or two of my Bikes I would like to use a rear hub motor that is used most of the time.
The main objective is Use the Rear Hub on the Flats, and only use the mid-drive when going up very steep and or long and steep roads. thereby extending the life of the mid-drive and my chain and chainring and cassette.
Now in the last two days, because of a suggestion by Neptronix , I have been considering using a 500 watt front motor on one of the bikes because it has a steel rigid front fork . But after many hours of research over the last two days , I am finding it is hard to find a 500w geared front hub that both has 6 bolt holes for my fork that can only use a disc brake , and is low cost . The cost of those that I so far have found is nearly the cost of a BBS02 from China .
In the Case of a Befang front 500 watt 48 volt motor it is over $400-$ 450 I would just get another BBS02 for even under that amount.
So unless I can get a front I 500w geared hub laced into a wheel with all the wireing preferably HiGo connectors , controller and display for $ 200 apx. , I will just have to get another base model BBS02 or ToSeven dm02.
With a Befang BBS02 , can put it on any bike that I have, the front hub would only work on one bike .

Yeah those $150 .00 1500 watt laced up wheels with a controller is hard to beat. The main reason I tried this in the first place was just to cheap not to.

I've run a combination mid drive and geared rear hub motor on a couple of my bikes, though the mission wasn't ..."deal well with long steep hills" I don't have any of those where I typically ride.

The most pleasant, issue free bike is a combination of a 500w geared rear hub and a 500w TSDZ2 torque sensing mid drive, with 5 speed rear cluster on the hub. The torque sensor lets me ride it like a normal bike, with a substantial boost from the rear hub ( controlled with a thumb throttle ) when I want it...mostly for speed or acceleration away from a stop light in traffic. It climbs the couple short, steep hills around here at over 20mph ( instead of four mph on an acoustic bike)

This distribution of weight, loads, torque, and wear seems to work out pretty well ( though I only have hundreds of miles on it, not thousands) Two 7 AH 48V batteries, cheap controllers, minimalist screens means that I have the advantages of redundancy and cheap , easy to replace parts.

Oh , So a person would have to buy a new 750 watt controller . Then it would be better to just
buy a 750 watt one in the first place. Glad now that I did not buy that cheap new 500 watt bbs02
from Amazon .
