Re: need kit suggestions, please

I think you will be very pleased with the GMAC + PhaseRunner kit from Grin. The variable regen brakes is a really big win. You will also appreciate the additional torque from the motor gearing.

Re: Proportional braking/regen?

After 1500 miles it has become about as natural as can be. Originally I thought I would want to have a proportional brake signal from the lever(s), but I rather like that the friction brakes are 100% not involved. The thumb throttle is inconspicuous and fits nicely between the brake & the grip. http...

Re: Proportional braking/regen?

I have GMAC+PR. Variable regen is brilliant and as said earlier, mechanical brakes are very very rarely required. I control braking power with a thumb throttle mounted on the left bar. Variable regen really is a lovely feature. I’m afraid I’ll never be happy on or in any EV that doesn’t have at leas...

Re: looking for a job in Solar that isn't construction/install?

Hi leffex, To answer your question, No not really. The reason I provided the brief description of my background was to sort of demonstrate that I did not come into this job from a related field. I have had a Homer Simpson like list of previous occupations including bulk coffee delivery, home brew sh...

looking for a job in Solar that isn't construction/install?

Hi guys, I hope this doesn't come across as spam but you all seem like an ideal group to mention this to. I have reading on E-S since about 2012 and I come here frequently (daily) to learn more about ebikes and the technologies associated. I have built 2 ebikes over the years, I commute 13 miles one...

It seems like the device you just described is exactly a cycle analyst. Just get one of those.

It has the particular capability he is seeking. Dual motor, dual controller, single display. No? Plus it’s super sweet :P

Re: This section has the wrong name

Amazed that I didn’t see the word sustainable once in this thread. I guess it’s a synonym for renewable but sort of a little bit more to the point.

Here is the shortest clip I have that demonstrates the sound. I occasionally make these how-to videos for new hires & such where I work.

Re: Inverter with my Solar system make a noise! why?

I had to chuckle at this. I work in utility PV and some of those 800-1800kW central inverter’s really can make some seriously loud, annoying noise at high gating intensities.

SMA is a very popular inverter and we’ve joked that it stands for Sound Making Apparatus.

Hello everyone, Even though this thread does not exactly align with my issue I think it provides a good backdrop to what I am experiencing so I chose to bump it, rather than start my own thread. I have a Kingpan KP600E-60L, 50v 10a charger that has begun to give me trouble. It is used to charge a 12...

Re: X-TREME XB-300Li MODS/HACKS/UPGRADES

I bought one of those bikes on Craigslist a few months ago with a dead battery for $125. A friend of mine had gifted me a 12S pack that came with a kranked bike he purchased used and wanted to run the bike on Lipo. The stock controller had absolutely no problem running at 12S and the bike is a real ...
