Very nice Mags!  I particularly like your accessory bag behind
the seat which holds your batteries and much more.

You're right on about desulfators and desulfation.  I've made
several small desulfators which develop the high voltage pulses
via inductive discharge.  Though they are not fast at desulfating
they are effective given time and very safe for the batteries.

I've seen a few ads for the kits from China and will have to
investigate further.  I'd thought initially about getting one of
the two cycle gasoline engine kits but now think electric would
be a better option.

Some of the kits are motors which rest on the rear wheel and
power it with a friction drive while others are front wheel hub
drive.  I take it you'd recommend the three phase front wheel
hub drive?

Again, very nice!  Thanks a bunch for the precis.

I do have a 12 Volt Lead-Acid Battery Charger that I've acquired
recently from China that has a pulsed recondition mode.  I've
used that already several times on automotive batteries where
it has done a splendid job of restoring capacity and I've also
used it on some SLA 7AH where it has resulted in some
improvement also.  Once I get my scope set up again and
my laboratory back in operation I'll be able to see what it
actually does and how it compares to the desulfators I'm
more familiar with.
Yeah i would go with the brushless hub motors. Very little to go wrong other than hall sensors going bad. Ive figured that if you leave the bike out in the sun where the hub takes on a lot of heat, then when you ride the use of the motor adds to that heat. Replaced them twice. The last time I used  linear or say analog halls. In that case the halls didnt work. What I found was that the hall sensor needs to pull down a 5v line to 0v.  But the hall didnt have the balls to do it. So since they were in already, I decided to experiment by putting a helper resistor from gnd to the output lead. First try, 1kohm and she runs just like new and havnt had issues since. Once the outer rim screws are removed, the cover on the motor comes off lifting it a bit at a time around the edge, using shims to help as you go around. The halls are on a small circuit board and tucked into small slots on the motor coil core.  YT has vids on it.  But other than that, after 13 years, just had to replace spokes. No biggy.  Im 240lb and the bike is about 70 lb with batts motor, small tool bag, extra tube and patches and an 18v ryobi tire pump. Pumped in about 45 sec. Highly recommend the pump.  Even though I use $50 tires Bontrager, cant avoid all the stuff on the road that can lead to a flat. But they do have a lot of resistance to getting punctures compared to cheap tires. Once had 5 flats in 1 day, with a hand pump. :'( :'( :'(    Used co2 inflaters but at 3 bucks a pop, the ryobi was a no brainer. 29 bucks but batt and charger separate. But I have a few ryobi 18 drills.
Got these in the pic below for work. Exotic and high end car dealership. Use them for keeping the batteries fresh and at 5a they charge quite quick for $19 ON AMAZON.Got 10 of them. Some .75a - 1.5a trickles are close to $50 and dont seem to cut it. The pulse mode restoration actually helps a beat battery, sometimes. But I always recommend just repl bad batteries. Doesnt look good when you sell an expensive car and it comes back with battery issues. Some of these cars it takes a lot just to change the battery let alone get to it to charge.

Chet,no discussion need :

                                               frequency modulation effect

catalogue page 6 : power output by 3000 RPM/50 Hz ( net- grid) and 30000 RPM/500 Hz                                                                                                   
                                                            by the same motor
         10 times frequency and rotations amplifying gives 400% output increase                                                                                                             

                                                     before 100% after 500%                               

                                                  power P /  power S / power Q

                now this 30000 RPM by mechanical transmission down to : 3000 RPM

                                                 frequency modulation effect                                         

                                                    by the same transformer                   


                       frequency/rotation modulation by variable speed drive or transmission

                                            " .......according the third power of speed ......"
     [0100] here for the generator : turbine torque proportional to the second power of Wind speed
                                                           turbine power proportional to the third power of wind speed

                              a motor  ?           motor torque
                                                          motor power

Taking a DC battery-set with DC-AC Inverter :
A. Conversion to 50 Hz by 220 V and 10 Amperes
B. Conversion to 500 Hz by 220 Volts and 10 Amperes
loading the variable speed drive motor

Battery charge time to become depleted/ empty : A. ? B. ?
                            " overunity"- question:: result = answer
                                                            A~ 1/10 B in cinetic/ mechanical force
                                                            A~ 1/1.  B in cinetic/ mechanical force
