Re: is torque a good predictor of how easy it will feel to go uphill?

I thought I would do a follow up. I ended up getting this bike from bikes direct and pretty happy with it. https://bikeshopwarehouse.com/cgi-bin/BSW_STOR20.cgi?Action=Details&ProdID=2594 I live in really hilly area and climbs hills greats. Sill have to work at it but it is definitely manageable....

Re: Trouble getting KT controller/LCD3 working with Voilmart motor

Just a follow up with this. I really like the KT controller + lcd over the one that came with the voilamart motor (sw900). The pedal assist is way more responsive, and the various pedal assist levels actually work, Level one maxes out around 150 Watts, configurable to be less.

Re: Trouble getting KT controller/LCD3 working with Voilmart motor

So it appears P2 needs to be set to 0 not 1.

It is registering speed now! Tomorrow is take it out for as spin, see if any other adjustments are needed.

No speed displaying with KT controller on a voilamart motor

I've got a 1000W voilamart motor that I was hoping to use a KT 48V controller with my kt lcd3 display with. * Throttle works * PAS seems to work (I had to switch around the wires a bit, see https://www.pedelecs.co.uk/forum/threads/power-issues-with-voilamart-kit.40299/) But I get no speed displayed....

I looked recently on HobbyKing and they don't seem to be selling Lipo batteries or very limited selection. Where is the best place to get a decent price of these now?

I've ordered a few ebike products from ebay, but this seller by far takes the cake for poor business practices. I'm writing here so that other's don't have to deal with the same hassle that I did.

For use as a Low Voltage Alarm, they are a compromise, as you pointed out, due to Voltage sag. A "hard" Low Voltage Cutoff(LVC), usually in the controller, is a much better way to go. They are fool-proof. What is the LVC set to in the controllers? Is it pretty standard and therefore prote...

Also, how do these alarms work, as a little bit of reading I'm doing states that there is "load" voltage and "resting?" (no load) voltage. Under load the V can get down to like 3.3V or something but then after no load, it move back up to 3.7, 3.8, etc. So if there is only 1 alarm...
