Re: Stealth & quick-ish e-bike for short commute, opinions

I recently ran across my old KLB panniers that I used on DayGlo Avenger (and previous bikes before I used motors) before I got the big metal box on there. I had pairs (mismatched in this case because it's what I had), bolted side by side on an old rackmount equipment rail. Fender washers on all the ...

Re: Single-speed track stealth ultralight

There might also be noise in the hall wires induced by the phase wires. Sometimes adding a small capacitor (0.1uf or less) in parallel with each one to ground cna help with that. Or adding one from teh hall power to hall ground, if the noise is in hte power line. Anotehr thread recently reproted dio...

Re: Hall Sensor or Phase wire making my electrics burn? (With video)

It has the ability to connect to an analogue ammeter (the ones with the needle). However, it uses the same pin as the thermistor so you can only use one or the other. The current limit is programmable though so I guess setting that to a reasonable value and using the pin for a thermistor makes the ...

Re: New "TSDZ2 Torque Sensor Central Motor"

If the jam caused an overcurrent at the battery from too much controller current draw, you might just have a blown fuse in the battery.

Re: Series wired battery gone wrong?

If you want to series two packs, you need more than switches in series with them, or else all you're doing is disconnecting the entire set from the controller. If you have them in parallel, you dont' want to disconnect either one, but instead always have them in parallel, so the load is less harsh o...

Re: Series wired battery gone wrong?

one pack measured 18.17 V and the other measured 290.24 volts. I'm assuming that "290.24" volts is a a typo, and it's supposed to say 20.24. Otherwise something is probably wrong with your voltmeter. ;) For series wiring that should have given me 38.41 volts but that 's not what my meter is getting...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

Depending on the space you would have left between the motor cover and the frame, once the axle is resized to fit the frame, you might be able to go with a 5 or 6 speed freewheel, vs say, an 8. It might be that even an 8 would still fit. Youd have to figure out what you'd have in advance. Often you ...

Re: Would you charge a 4s LiFePo with a "15V" wall wart (intended for charging a 12V SLA)?

What does the waveform out of the wallwart look like? Is it actually good DC? Or lots of AC ripple in it? I've run into lots of cheap SLA-powered stuff that lets the battery do most of the AC smoothing, and I wouldn't do that to a non-SLA battery. (Wouldn't do ti to SLA either, but it handles it bet...

Speed in both directions looks the same to the naked eye.

Re: Help Please, Bike cutting Out

It probably is a bad channel on the BMS, or a wiring issue on the balance wire for that group. But: When you put the new cell in, did you first charge it to the same state of charge as the rest of the cells? If not, then you might have to let the system sit on the charger for days to weeks to bring ...

Re: Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

The rear assembly of the trike including the dropouts are aluminum so I don't think I can spread it to 142mm. It was hard to even get the 135 Crystalyte in there. If you don't need all of the axle space for a big gear cluster, you can modify the axle to fit, by extending the flat part of the axle a...

Re: Front hub direct drive suitable for fatbikes?

Rear hubs allow space for cassettes so I don't think that would work well. If you mean taht they're dished to one side, that's generally not the case with hubmotors (vs normal hubs). Just make sure the axle shoulder to spoke flange distance is equal on both sides. Or just lace the wheel as a dished...

2)Perhaps I could simply flip the rear wheel over to put the sprocket on the right hand side. There is a lever for the rear (drum) brake, which would then be on the wrong side, but I could probably run a cable in place of the rod. Will your drum brake operate correctly rotating in reverse?
