    Universal AWD mid/front hub bike

    Allright. You will end up with two controllers and have to design something to link them to provide AWD or orchestrate that if you want. A big problem though is that the mid drive's torque per mph is highly variable but the geared motor's is not, you can imply a lot from the throttle position...

    Endless Sphere Merch?

    Yes, backstory on that: ebikes.com or endless-sphere.com

    Endless Sphere Merch?

    I say yes to it, especially if a portion of the profit goes towards donations. It's a good idea. There's one problem though.. we are about to change our URL to ebikes.com/sphere.. and that will probably happen during Fall to Winter. The merch will need an update. You may want to hold onto that...

    New 1000w Geared hub MXUS XFC19

    Yeah you want a direct drive for that. Unless you have a fatbike frame and then you can install some of these very wide geared motors that are out lately.

    What's your definition of high speed?

    30MPH Commuter : BBSHD vs QS205 24*5T

    You don't really have hills and a 30mph top speed requirement. That means a 1000W rated motor would do fine. A GMAC or all axle motor would be totally suitable for this. Both would have higher efficiency, be lighter, and have less maintenance problems than the BBSHD. Anything is lighter than a QS.

    Pedal generator to hub motor, no chain

    I'm not giving someone on mount stupid more views, youtube has an excess of that kind of content and it doesn't deserve more engagement 😅

    Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

    Okay, just came back from a quick ride! The crank bolt sticking in the pedals is smacking ever so slightly and needs a millimeter shaved off. Cornering isn't very good. I think the taller front end has a negative effect. I think i need that 18" wheel now. The suspension was really great. I...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Check out the first few pages of this thread. I used RC Lipo, but i don't recommend it. You will need a specialized battery to push this much power on an ebike.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I used a 18FET 3077 infineon clone controller and was pushing 48-72v and 60-100A on my 4T. My best advice is to not buy the stock controller, it's garbage.

    New 1000w Geared hub MXUS XFC19

    To go high speed you have to fight two things: - Controller eRPM limits, IE you need a specialized controller for this motor. - The motor's low efficiency relative to a MAC or DD prevents you from running those high speeds for a long period of time, even if you achieve them. You want high...

    Oh, i see. Yeah, i would expect most users to lose their PGP key, even if we could get them to somehow make one. Yeah, your results are no surprise. Many of my emails got in a data breach at some point in time. Few systems are safe in the current cyberwar. Microsoft's email systems got blown...

    Chaos GT1600

    Links in my build threads are in my signature. I agree with E-HP. I'd try connecting and reconnecting everything, jiggling the screen and connectors, and if that fails, i'm betting you don't have electronics diagnostic equipment on hand, so it'd be a good idea to order a new screen, and if that...

    Adapting this to work on a website instead of a git repo or email client would be very difficult. Yes, huge problem that the entire internet is going to have to figure out soon. FYI, the '100 most used passwords' comes from not our own password database but from the haveibeenpwned service's...

    Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

    According to my email, i have the lightest mid drive parts that let me run the drive on the bike coming my way. Cool! I'm thinking it belongs on the front to act as ballast to distribute the weight better.. and also give me the ability to gear it for 40mph. Sounds like good times to me!

    Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

    Good news. The front suspension modification is done, and the cables have been reworked. The bike is ready to ride. I replaced the front 113mm wide bottom bracket with a ~128mm wide BB, and the mid BB went from 110mm to 123mm. I put some spacers between the front chainring and the crank, the...

    Mini Hiryuu - Mid power ebike

    Mini hiryuu is coming together! I bought a 24" front wheel with disc brake but decided i really didn't like the look of it. Put a 26" x 1.95" up front and i have a 24" x 2.4" Kenda cargo tire out back. The front tire measures as 25.5" and the rear measures 24.5". At a distance, the tires look...

    Can we please keep this topic to the 1500w leaf motor? Or start a motor design thread since you're talking about theoreticals?

    Ok, what do you mean by 'it's flashing'.. is the screen cutting on and off.. or some icon flashing on the screen? if so, what icon?

    Universal AWD mid/front hub bike

    I'd consider a pair of small geared motors for this application. Here's the current efficiency champion of geared hub motors climbing a 10% grade, no sweat. Might overheat in 10 minutes of this, but, it could handle lesser grades for long periods of time.. if your terrain is not too steep, this...
