just checked around endless-sphere... seems like this a snake oil. :-(

http://www.busettii.com/battery-for--mini-40-mile-lithium-battery-52volt405211.html what is the battery chemistry? it's on the sphere wiki, as existing but rare? What are it's properties? Also, on this site they say that have AC hub motor with variable torque? how does that work? Auto phase...

Is it possible to be charging the pack while discharging? Or should i have just have two packs, one for discharging, and one charging?

Can this be achieved Thinking of trying to charge my 48v 10AH pack with solar. Mount a 100 or 200 watt panel, I have room on my bike , 100 watts weights in a 1.9kg for a flexible panel I don't know if my 'poor' calculation are correct but 48v * 10AH = 480 Watt hours in my pack. 8 (number...

Hi, I'm getting my hand on http://www.ebike.heinzmann.com/images/ebikesystems/phocadownload/Fahrradmotor-CLASSIC_DataSheet.pdf soon, Is it possible to convert it to any kind of mid drive setup, drive LH crank, Drive RH Crank? Drive Read RH Large Sprocket? or any of the other wonderful...

If your using a celllog 8s? I presume it can monitor 8 cells , however 36v is 10s? how does one monitor all cells?

after a bit of you tube trawling, I found this http://www.youtube.com/watch?v=T7D44i8cJYo it uses a small RC Zenoah G260 motor. very nice. no information on the alternator either. wattage output or voltage. there no reason why you couldn't add a chain to this an let you bike recharge through...

I found http://www.freeprawnracing.co.uk/reedy-40c-5000mah-lipo-battery-efra-brca-legal-as685.html are they any good for ebike use? Thoughts please. Cheers, Lee

i saw this.... maybe can be adapted for ebike recharging use. http://www.youtube.com/watch?v=EnYUO1PW10M I wonder how much life you can get out of one of those motors. 10 hours?

interesting, i wonder if you take the further and use some PC water cooling tech to get that down further :-) presumable you could use a water jacket to dissipate heat too :-) , as long you kept the water out of the motor! :-)

thanks for all your replies!!!!! http://endless-sphere.com/forums/viewtopic.php?f=6&t=5919 seems to outline adventures with RC type motors. They are designed for low weight , low torque applications. Bikes are too heavy!!

I found this XYH80-100-A 180Kv Brushless Outrunner http://www.giantcod.co.uk/xyh80100a-180kv-brushless-outrunner-7055-p-404968.html which is an RC motor, price seems good, i presume it would need a reduction gearbox and suitable controller??????? or is a just matter of plug and play (pray!!)...

The Dr....., as awesome as ever!!! wow, so the next limit in electric bikes will be domestic house power supplies. :-)
