Anyone know what the maximum practical eRPM for these are? Anyone try to run a 6374 type 149-200Kv winding range RC motor off one of them?

@Avitt S3X is the three speed fixed isn't it? Which does not have the same internals as the standard three speed which should still be old style four pronged sliding clutch shifting?

Yes, and No. High school and 100 maybe 200 level college course physics and engineering is indeed calculated simply by the coefficient of friction and the force. BUT ----- At a higher level of understanding one finds out that things are a whole lot more complicated then that simple calculation...

Yah, I learned my lesson years ago when I had a road bike that I had put a DIY RC friction drive on. WAY FAST especially when tucked in nice and tight, I built my own throttle with a tiny squeeze button buried in the down drop bar tape. One day, screaming down the road at 30-mph I saw a...

Nice Find !!! (you posted while I was writing my post).

Yes, it is possible to find circuit breakers that are capable of handling 36VDC but you have to be very careful about making sure it is actually rated for higher DC voltages ----- Many circuit breakers are only rated for AC not DC use (there is a huge difference in the engineering required...

What people don't understand is that there are other court cases that very clearly established the line where the "right to travel" ends and "the privilege of operating a motor vehicle on the public right of way" begins. I know because I've used the very early 1900's pre-gGreat-Depression...

Only once could it have been possibly construed that I "ran" from a cop on a bike. There are unfortunately many people including some who where uniforms that believe bikes do not have a right to use the road and will attack and harass bikers who do use the road and do so with confidence and...

If you only need two speeds have you considered using a retro-direct type system on the motor output shaft. First put a left hand threaded 1.37x24t freewheel shaft adapter mount fitted with a south paw 24t freewheel on the motor shaft followed by a 30mm right hand thread freewheel with a heavy...

If you are happy with how fast the motor spins as you have it right now (the motor is not spinning too slow for you to comfortably pedal along with and you are not wishing the motor would spin faster to keep up with how fast you pedal). Then you don't need any more voltage. Just increasing the...

Been a week or so since I've checked this thread and several pages have been added. I read/skimmed what has been posted since I last was on this thread and have a few points to make: #1 = There is a new-ish guy who posted on the thread that he is installing one of these kits on his bike and...

Oh, yah, someone also asked if its possible for an internal geared hub to take the power this kit puts out. Someone already is running one of these on a 170mm fat bike version of the Sturmey Archer 3-speed gear hub: Clickable link to article= Electric-Fatbike.com 3-Kw cyclone with Sturmey...

Okay, first off somewhere I read that the planetary reduction on this kit had a 4.91-to-1 gear down ratio. This did not sound right to me. Picture on the first page of this thread shows a simple single stage planetary reduction unit with an input sun gear will 11-teeth and three planet gears...

It doesn't surprise me at all that it wore out considering the Matex LGU 75-S is only rated for 1/17th of the torque compared to the Matex LGU 120-M which by its rating should be just strong enough to take the full combined torque & RPM loads that the 3-Kw cyclone motor is capable of putting...

I did notice and like that AFT says on their website that they intend to install a stronger version of the plastic gears in their version of the 3-Kw cyclone. If they follow through that would be a source of replacement gears right there, both for their supposedly higher strength replacements...
