    Want to move away from Proprietary to Mainstream

    What happens if you hold the brakes instead of tapping them?

    Can I share my battery ground wire with a DC DC converter?

    Sadly he’s not with us anymore, but his contributions continue to provide great benefits. I learned a lot from his posts even before joining ES, and refer to the unofficial Cycle Analyst user guide all the time; so I agree, thank you teklektik. 👍...

    My econo-e-bike

    I decided to get the good stuff after I do my rewiring/recabling so got some cheap split loom stuff for now. Definitely doesn't look as nice as the good stuff though, but better than the wire mess. Here's before and after pics of how the sequined panties fit, lol.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I'm looking at certain model years of the 24" Specialized Hot Rock and Rip Rock, converted to 20", before bikes started hydroforming the tubes making them all swoopy and hard to mount stuff on. Both come with short travel suspension forks and rear disc brake mounts. I'm going to see if I can...

    Looking for recommendation on first Ebike conversion kit

    Maybe. The axle spec seems odd Wheel Axle: 175 x Φ10mm

    Looking for recommendation on first Ebike conversion kit

    Your range and speed expectations can’t be realized on a $750 budget. 25 mph and 40 miles may be doable, with a fair amount of pedaling. I would spend about 1/2 to 2/3 of the budget on the battery. Terrain/hills? Is that rear wheel a thru axle?

    Coasting/Regen/e-brake, and dual motor behavior

    What you are describing sounds like slide regen. I had my last controller setup that way, and I actually liked it. It forced me to hone my throttle control skills (I put a button on my bars that applied 50w of throttle which was enough to coast forever and give my wrist a break). Anyway, most...

    Looking for recommendation on first Ebike conversion kit

    How you will be using the bike plays a big factor when it come to the various options. Are you using it mainly off-road, mixed riding, or street. Steep hills? Battery size may be limited. Also, reasonable price doesn’t provide much, your intended budget would be more helpful.

    Speedometer glitch reading 99+ mph

    At the very minimum, I’d replace the throttle. You may have more than one issue going on. The throttle may get you up and running. I’m trying to recall, but I think the bbshd doesn’t need the speed input when running throttle only. EDIT: I forgot you’re using the PR, but same note applies. On...

    Can someone tell me how to hook the sine wave up

    A lot of the cheap controllers (including mine) use a red wire, like the one with the ring terminal, as the electric door lock. On mine, connecting that to battery positive turns on the controller. The two red JST connectors are likely for alarm. Alarm requires power even when the controller is...

    My concern about ebike battery fires1

    Nice shed. 👍 I’m just starting with solar in my backyard. It would be easy to add an AC outlet by the patio, but I want to see how far I can go without it. Right now I only have one panel, a controller, and a small lifep04 battery. I run the pond pump, and run/charge my usb devices. I’m ready...

    Bought a bike, thought it would be an easy fix. 🤦‍♂️

    Is this a factory ebike or converted bike? It’s possible that the power on/off function turns on both the controller and battery. There are some Lishui controller experts on the forum, so maybe they can provide some insights.

    Amberwolf disappearance and newbie help requests :(

    I noticed folks are chipping away at the Unanswered posts, but it's shocking to see how many there are prior to April 24th relative to how many there are after. My thought is that we've (I've) gotten a bit lazy, leaning on amberwolf to field so many of the newbie questions, and placing too much...

    Best way to connect 4 separate 12s packs?

    I’m wondering if using an active balancer on each of the four packs, then two volt meters to monitor the voltage of the two 12S series portions to ensure they stay at about the same voltage would be sufficient. https://www.amazon.com/Lifepo4-Equalizer-Balancer-Inductive-Transfer/dp/B09C3HRMFG

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    My wife is shorter and growing shorter, so the lower the better. I’m going the lazy route with the wheel already radially laced. I was originally going to go with a BMX frame, but there’s more room to spread out on the small mtb frame, in case I end up riding it. Thanks. I read your build...

    Best way to connect 4 separate 12s packs?

    Just gathering info for future reference. Do these packs regularly go out of balance? It seems like that would be problematic for a EV when it comes to charging due to the extra time for balancing. Or, do they use an active balancing circuit? If it were me, I’d run them without a BMS for a...

    Questions when purchasing a sinewave controller

    The differences will be so small that you wouldn’t be able to tell. If you want the motor to run more quietly, then switch to sine wave. At least then you’d be able to tell the difference.

    Best way to connect 4 separate 12s packs?

    You are essentially making the four packs into one big pack by paralleling each group, so 24 groups in series requires 25 parallel connections. Since your subject asks for “the best way”, maybe define what best means. You can either deal with the headaches up front and have an easy charging...

    Best way to connect 4 separate 12s packs?

    I did the same thing and came to the same conclusion. It looks easy on paper, but once you throw in how the packs will be physically located, it quickly becomes a nightmare.

    Digital Multi-meters DMM - Upgrade Time - Suggestions?

    Not a replacement for the bench, but small and cheap enough to keep in the bike bag and not to worry about it. Reasonably accurate and good enough resolution for ebike work. ANENG AN8008...

    My econo-e-bike

    I was staring at my maze of cables, while sitting on a bench taking a break. What a mess. At this point I'll take sequined panties, covering up streaks in the underwear lol. I'm also going to vinyl wrap my triangle battery. Still deciding on what though. The shark got a lot of attention from...

    New Alibaba Cmacewheel/Toodi K20 E fatbike [Makes very loud and strange noise].

    I would check the cable from the controller to the motor connector for possible damage. Even if not visible, I’d wiggle and bend the cable back and forth a little along its length and see if the symptoms change at all. Sometimes a motor groaning could be from an intermittent phase wire...
