    Rear wheel 8 to 7 speed

    Do you have more on this? I recently went to a lower gear for big hills carrying a heavy load (~300 # with trailer). I'm also frequently biking w/out any motor input at all, which I've heard can be bad for hub motors. What makes low speeds and driving w/out motor input bad for motors?

    How to enclose a buck converter in a battery box?

    Was trying to make a 12v battery box on the cheap with a 18650 36v, 12ah battery pack I have. I got a 20 amp buck converter, and realize this thing is going to get hot....I haven't tested how hot yet, but almost certainly too hot for a plastic box. Is there anyway to safely enclose this? Or...

    Lesson learned in coiling motor power bundle

    Bundle shot good, so not a bad connector: .3 ohm on Yellow hall, and ground wire. Everything else 0.1. Not looking like I can find a replacement locally... Might have it a go while I wait.

    Lesson learned in coiling motor power bundle

    You may very well be right. However, the whole bundle was warm to the touch, but was way hotter where it was coiled near the connector. The battery wires were fine. Definitely not going 15mph...8 maybe?

    Lesson learned in coiling motor power bundle

    https://imgur.com/a/a0H2bYi This was under about a 300# load on a ~16% grade, on a ~62°F day. No smoke or odor, just instinct told me to check...good thing I did. Current limited to 20 amps, which I just dropped down to 15...luckily just damaged the outer shield, and not the internal...

    2x ebikeling 500w front hub conversions in 79'er (27.5 in the back, 29 up front). Hers is an off the shelf Cannondale Tango 4, with a Surly ECR Fork. Brake upgrades coming, though the MT200 hydraulic disc brakes have surpassed expectations, so might just leave it. His is a frankenbike. Marin...

    New em3ev batterý pack

    I recently bought 2 batteries from them, and they provided 2 adapter cables to xt60 female for use with a Luna charger. I'm sure they can make you something. The adapter cable has a brand stamp of "cusmade"... "Custom made", probably.

    Rear wheel 8 to 7 speed

    Didn't know there were "cassette hub motors". Sounds like that's what OP should look for, and just use existing group set.

    Rear wheel 8 to 7 speed

    I think the fundamental question that hasn't been answered yet is whether your 8 speed cassette will fit a motorized rear wheel free hub body. I do not know the answer, but am curious. Generally speaking, 8,9,10 are wider than 6,7, so it likely will not fit. That bring said, what E-HP said is...

    Hub motor locks?

    Ha! I stumbled into the same idea, and think I found some open end lug nuts that should work.

    Hub motor locks?

    Jump bikes (rental bikes) have a keyed locking...nut...or something, on the ends of the axles on their front driven bikes. My Google-fu has failed me, and can't find anything comparable for sale. What good ways are there to keep them from being tampered with?

    thanks. How do I go about checking the balance? Does that require tearing the pack apart?

    Help troubleshoot ebikeling waterproof motor - no worky

    Quite possible. First build, and I have no idea what to expect. However, it generally only occurs at very high load, going uphill, with a trailer. Probably close to 300 pounds total. Another forum indicated that is normal behavior for a high load like that. So, could be the battery, could be...

    Any experience with Energie Cycles? (Short person bike)

    Been looking for a do it all step through for my wife. Came across the "e-fat step", which looks perfect. Folding is not needed, however, and company seems pretty small. Not a lot of press or reviews, but not sure I have a lot of concern about that, either, since all bikes in this range are...

    Using cheap adjustable power supply to get 80% charge?

    So is the one I posted. You can see the indicators on the LCD display. My understanding is all power supplies on a battery will be CC until the load (battery) reaches the dialed in voltage, then switch to CV at virtually no amps, unless/until the battery drops below the dialed voltage again, and...

    Using cheap adjustable power supply to get 80% charge?

    11 amps is overkill; not sure many batteries can take that? Right...pretty minimal risk.

    Using cheap adjustable power supply to get 80% charge?

    Anybody use something like this for multiple battery types (eg 36v, 48v, and 52v batteries?) https://www.amazon.com/Variable-Digital-Adjustable-Regulated-Switching/dp/B07YC6LXNT/ This is one of those awesome products that fakespot rates F, and reviewmeta rates perfect. Anything to look for...

    Help troubleshoot ebikeling waterproof motor - no worky

    New controller putting out 4.75 volts, and throttle works! Haven't tested the PAS yet. Learned that the throttle is also limited by the PAS level; 0 = no throttle. What does it mean when the battery capacity goes down to say 25%, then "regenerates" back to 85 % after stopping for a minute or so?

    Help troubleshoot ebikeling waterproof motor - no worky

    Tested it tonight. In this image for reference, Pin 1 is furthest left, 3 furthest right: PAS connector puts out 5 volts from pin 1 to 3, and 1 to 2. Throttle connector puts out 4.3v 1 to 2, and 0.7v 1 to 3. What should it be?

    Nope, had no idea. but I have a new controller on the way. I'll play with it. Yup, no bent pins, and fully seated to the line.

    Help troubleshoot ebikeling waterproof motor - no worky

    ^ awesome, thanks for that. They look very similar. I found that the "walk" feature (down button for ~6 seconds) does work, so this implicates the controller. Tried both settings of p09 and all 3 settings of p10 to no effect. Let ebikeling know; hopefully they can just send me a new controller.
