Re: 70$ Li-Ion Battery Pack 48V 10.5Ah 500w output

Sent you a PM a few days ago, but you haven't read it yet.

I'm wanting to get 3 packs.

Re: Ok, so I crashed again today...Is it time for a trike in the city?

To me, it sounds like a fatter tire will benefit you before adding another wheel to the dynamics. A 2.4" tire would have laughed at that gap and a 4" tire wouldn't have even known it was there.

Re: Warning for those who bulk charge using bench power supply

I'd say a proper charger or at minimum a LED driver that does CC/CV Meanwells are great for that task. I like the potted units as they are very robust and can travel. Some are good enough for bike mounting. One that would put out a comparable wattage to your 5A/60V setup should run under a hundred. ...

Re: Will Statorade make a hub motor quieter?

Statorade will only help in cooling the motor. Has nothing to do with sound.

If you want to make it quieter, get rid of your squarewave controller. Phaserunner would make it super quiet and stealth.

Re: Gonna get a used model S

Honda Accords are notoriously cheap to maintain, efficient, reliable, and enduring. 9 years is nothing for a Honda Accord, I regularly see people running them from the 90s still. You've got 20 years on those guys. I want a Tesla Model S too, but I know it is a luxury car and as such, I won't be buyi...

Re: Best way to unscew hub motor screws?

Best is to get a long HEX shanked bit and put into a racheting screwdriver that you can press your weight onto. Also get a closed end hex wrench of appropriate size to turn the bit as you press down. Make sure your bit fits the screw's profile perfectly. Take your time to find a bit that sits in rea...

Where are you located and how did you source the scooter? It's a difficult to get one here in the States.

Re: Motor noise - why are some motors silent?

This may be a silly question, but why do some e-bike motors make a lot of noise, while others are perfectly silent? Are there fundamental differences between the way these motors work, or are some motors simply tuned/built/designed more quietly with casings and bearings that cause less noise? There...

Re: Anybody see any problems with this Starter Frame and Component List

If you're willing to spend $1,500 on a conversion, you might be better served to convert a used bike (you'll get much more for your dollar) OR buying a prefabbed electric. There are some good prices/bikes nowadays. There's much more choice than say 5 years ago. For instance, this bike here is sold b...

Re: Power of a 250 w LIME Motor

It could have something to do with the disparity in motor ratings. Manufacturers tend to bend the truth sometimes. Your 400 W could be a peak rating while Lime's could be a continuous rating of 250W. Another thing, being rated for public use, I'm sure they don't want to seem like they have too much ...

I certainly do not have experience with those. But in my experience with ICE motors, in general, I understand that they create vacuum all on their own, which, in this case, makes air flow through a material through which snow/water does not. I do not see a situation in a battery that would allow air...
