    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...

    Thanks! You read my mind because I was just getting ready to looking into where to order them from. And thanks for the tip.

    Problems With Tq Speed Sensor

    The owners manual states “oversize 15mm axles, integrated dropout speed sensor, exclusive plastic motor covers.” Would it be possible to provide a pic of the sensor?

    How do I go about choosing a replacement front suspension fork on Arrow 9?

    Yours is threaded, because there are threads on the fork steering tube used the secure the fork. Threadless steering tubes are just a straight tube, and the stem clamps to the steering tube, securing the fork.

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I’m back to planning an ebike build for my wife. I’m not sure whether she’ll like it or will stick to it, but I’m also building it with the possibility that I may ride it if she loses interest; so easy to modify for higher performance later. So far I’m set on 60v and 20” rear hub, on a 24”...

    Want to move away from Proprietary to Mainstream

    How have you been maintaining the battery? Letting it sit for a year isn’t good. Can you measure the voltage?

    How do I go about choosing a replacement front suspension fork on Arrow 9?

    I watched a YouTube video where you can clearly see the hex bolt on top of the stem. There were only a handful of decent forks made before the transition to threadless, but anything made today is pretty junky.

    How do you feel about 60v bike controllers?

    I just watched a YouTube video on one of the new crop of 60v bikes, but it had a 17s pack. It seems like the only voltage level without a defined/consistent spec.

    Amberwolf disappearance and newbie help requests :(

    He responded to my first post on ES. As a newbie, I literally doubled my ebike knowledge by reading just a few of those initial posts.

    Speedometer glitch reading 99+ mph

    No, you have bigger problems and messing around putting $500 of quality hardware at risk, which you already have done, is not a prudent course. The behavior below is not normal in any condition, but could indicate a hardware fault. The motor spinning without throttle being applied points to a...

    Speedometer glitch reading 99+ mph

    Ya, makes sense now. How comfortable are you with opening the motor? With the conversion, it’s unclear why the speed signal needs to be routed through the motor housing, so seeing how it’s wired internally might provide some clues. It also could be where the problem lies.

    Is it possible to convert this 20" alloy wheel to quick release or thru axle?

    Sorry, didn’t notice the other scale on your calipers.

    Speedometer glitch reading 99+ mph

    Did you perform the conversion to the phase runner yourself, or did you purchase the bike already converted?

    Speedometer glitch reading 99+ mph

    I’d replace the speed sensor since it seems to have been acting up for a while.

    Was the system functioning properly before experiencing the problem?

    Speedometer glitch reading 99+ mph

    amberwolf cautioned you against grounding the wrong 5v line, but it appears you grounded both “I measured the.3 lines with multimeter, 2 are 5v 1 is ground i guess I tried grounding one then the other, both times, it just disabled the throttle.” Grounding the 5v supply line can fry the...

    WHAT REPLACEMENT DISPLAY DO I NEED

    Based on the owners manual wiring diagram, it looks like only power on/off, battery level, and headlight on/off are the only functions supported by the display. The text alludes to power levels also being supported, but that’s not consistent with the diagram. I’d run it without a display, and...

    WHAT REPLACEMENT DISPLAY DO I NEED

    The controller is the box the display and motor connect to. A pic of that would be helpful.
