Good morning all I cut the plug off the end of the 2A charger that came with the 36V 20AH pack from Headway, installed a couple of alligator clips, and connected it to the pack. The LED on the charger blinked 3 times red then the blower came on and the LED went constant red. The initial...

Good Morning All -Thanks everyone for the change in direction of this thread; now we are getting some where. Grant

Malcolm, that is very slick! With your ingenious motor mount and the eccentric lay out of the transmission “Bob truly is your Uncle”. Way to go. -grant

Good Morning All That double freewheel system also caught my eye, demonstrated about ¾ of the way down on their home page. http://www.cyclone-tw.com/index.html How does it work? The crank is obviously independent of the motor, but is the motor independent of the crank, in other words can...

Good Morning All Rick posted this cyclone disassembly guide on this thread. http://endless-sphere.com/forums/viewtopic.php?f=2&t=2809&st=0&sk=t&sd=d I believe the techs a Cyclone-USA will reverse the motors for their customers. This keeps the warrantee intact. -grant

Thanks eP for all your help. I think I now have a very basic understanding of these curves. It seems that max power is 600 watts at 1800 RPM pulling 36 amps. Does it seem reasonable that the Torq and the current scales are very close, columns 2 and 4? Also I suspect that it is not a...

EP thanks for your patience. Is the first column % of Watts in relative to Watts out and related to the curve marked EFF, the second column Torq is Newtons or in lbs associated with the curve that peaks at 600 RPM 40 Newtons, the third column watts, fourth current in amps?, and the fifth...

Thanks Miles, but what is ment by efficiency? I thought the efficiency would be watts in compaired to watts out which might be the third column. Wouldn't watts out, if that is the third colume and two lines that peak at 1250 RPM and 800 somethings be power out or total hourse power. Also do...

Good Morning All I like your mid-drive idea. An intermediate jack shaft seems like an elegant solution for a foot forward or recumbent bike. I have thought about driving the left side of an intermediate shaft with a motor and using the RH side for power to the hub and input power from the...

Good Morning All How is this used in practice? Setting aside the crank input. If you are crusing along with your 3 speed hub in 1 to 1 at 80% motor Rpm (max efficiency) and the grade increases, what does one do? If you want maintain your speed do you up-shift decreasing the motor Rpm towards...

Miles Thanks for the link. What has become of the production run? "Maybe, with Randy's guidance, we could produce a batch of these as a joint project?" Also this motor obviously fits between the cranks, how long is it or how long would a motor be to fit between the cranks? Did you...

Good Morning Miles What motor is it? I thought Draper’s motor was shrouded in secrecy. –grant

Opps :oops: -now I understand. Sorry TD -grant

Thanks TD, I think. :? I may be playing the straight man in this but, what is a hubbie bike? Google only gives up references to what husbands are doing with bikes. -grant

It looks like the Cyclone 1000W kit. The kit is $428 USD on the Cyclone TW site. http://www.cyclone-tw.com/dc24.htm Also, is anyone familiar with this little folding bike (featured with the kit). I think it is very cool. Obviously the rear triangle was built for something other than a 20...
