    Max eRPM for Sensorless Infineon sold by EM3ev.com ???

    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?

    -Sturmey Archer IGH for mid drives-

    @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?

    Solution for rainy condition usage of friction drive

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    Anyone get chased by law enforcement on an ebike?

    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...

    Anyone get chased by law enforcement on an ebike?

    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...

    Two speed gear box for e-cargo bicycles?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    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...

    new cyclone 3000 w mid-drive kit?

    Yah, I bought some ultra micro (postage stamp size) ultra light indoor RC model aircraft receivers (think RC model aircraft about the size of paper airplanes) from an Ausi place online that is one of the few places that sells them and was surprised at how favorable the conversion rate was then...

    new cyclone 3000 w mid-drive kit?

    Actually that gear box you link too is just about right for this motor since the cyclone 3-Kw motor kit is rated for a maximum output torque of 100-Nm and it can handle that level of torque well into a high enough output RPM for almost any mid-drive e-bike application (As shown in this...

    new cyclone 3000 w mid-drive kit?

    It also looks more like a demonstration-model/educators-tool/toy then an actual fully functional piece of machinery expected to provide solid reliability for years of service on an e-bike drive. Checked out the website he got his parts from and they have some nice high quality ready made gear...

    No --- A "battle robot" is something that mechanical and electronic nuts build and put in a big pit with others creations and try to destroy ever other robot, last one standing is the winner. Basically, robot cage fighting for nerds. The kind of sport that college kids at MIT and similar...

    new cyclone 3000 w mid-drive kit?

    @ emaayan I don't get the banana reference. As to the gearbox question, I have looked for a long time for a good source of gearboxes myself and have yet to find anything that provided the level of quality, selection, and reasonable price I want without having to order them in truck load...

    new cyclone 3000 w mid-drive kit?

    And if you just want the motor and its planetary gear box alone and are going to get/make your own mounting plates and use your own choice of controller then Sick Bike Parts is selling just the motor head alone and they are a U.S. domestic seller...

    Looking for a rim

    My suggestion for an alloy rim would be a "Velocity Cliffhanger". I've only personally used their 48h and 40h versions but they make a 36h versions as well. I usually use 13g/14g single butted spokes with them but have laced with straight 13g spokes as well. Can't guarantee they would work...

    When to pedal

    I personally pedal almost always and I have to be really tired in order to not pedal. There was a gentleman on another forum (general bicycling forum with an e-bike sub-section) who actually worked out the math for one of his build and found that in general unless your legs are inside of an...

    Cyclist vs motorist

    And in response to those who have disagreed with my statement that a motorist hitting and killing a cyclist ins't always first degree pre-meditated murder but many times is rather a case of culpable negligent homicide (very similar or the same as the more commonly known "Manslaughter"...

    Cyclist vs motorist

    I am well aware of the issue as to "presumed innocent until proven guilty" and the quite often absence of sufficient proof. Historically, that is actually the original legal underpinnings for mandatory license plates on automobiles, originated back in the very early part of the 1900's...
