Re: PWD's Rocky Mountain Blizzard - mid drive

The bike had been working well and I was finally able to test it out in some proper snow. The bike is a lot of fun; I've also aired down the tires for more traction. It does exceptionally well on semi-packed to fully packed snow. Anything deeper than about 20 cm of snow and it becomes very difficult...

Re: PWD's Rocky Mountain Blizzard - mid drive

Ever consider heated grips? I started looking at them after reading DrkAngel's Snow Beast thread. They don't look like they draw too much current. Folks I know with them on motorcycles say they're pretty effective. I am definitely willing to give heated grips a try. After my bar mitts are tested in...

Re: PWD's Rocky Mountain Blizzard - mid drive

So the cold weather and snow are here. I've had the bike out a few times in some light snow and it is a lot of fun. The limiting factor for ride time is the time it takes for my hands to freeze. I've ordered some inexpensive "bar mitts" to help extend my riding time: https://ae01.alicdn.com/kf/H4ddb...

What about the SuperMoto X with GreenGuard 26 x 2.4 ?:

Re: PWD's Rocky Mountain Blizzard - mid drive

That is correct, they both connect to the axle. I'm not sure if adding the fender bracket to the clamping mechanism of the quick release skewer is a bad idea though. I failed to tighten my quick release down all the way which led to my wheel falling out. After double-checking them; they seem OK now ...

Re: Charging and Balancing Questions for LG HG2 pack (14S/20P)

Hi Gary, The standard rated charge current is 1500mA per cell, so 15-20 amps for 20P seems safe. I would leave it at that. The minimum cell voltage of 2.9V isn't conservative enough for my taste. I would say around 3.0V - 3.1V per cell for the BMS and 3.2V - 3.3V per cell or 44.8V total pack voltage...

Thanks E-HP for the info. I ended up ordering the blue LED volt meter; hopefully it is usable in the daylight. I've had good luck with blue LED meters on my commuter build (green wasn't bright enough). Also, the voltage on the Cyclone controller app is off by at least 2 whole volts. Here is a shot f...

Re: PWD's Rocky Mountain Blizzard - mid drive

I've added an inexpensive cycle computer to track distance/speed/time. Some notes for future reference (captain's log): The last two rides were both approximately 16km each and I hit the controller LVC (approximately 49V) of both times. Ambient temp has been around 8 to 9 Celsius. Avg Speed was 28 k...

Thanks for the suggestions. I went the cheaper route and purchased separate meters. One of those inexpensive bike speedometers and one of the voltage display's that E-HP linked.

I'm glad shifting gears is fun! So the motor doesn't force your pedals to spin? Look forward to seeing how the drivetrain holds up. That's correct, the motor doesn't force the pedals to spin. There is a freewheel on the motor sprocket and a freewheel on the chainring/crank. Suddenly I have the urge...

I had the bike out for it's first shakedown. The first thing I noticed was how much torque this thing has. Due to the poor throttle modulation ( I blame the controller), the first couple of gears were almost impossible to use without wanting to flip over :shock: For what its worth, I am using the fo...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

Leafbike tends to be all over with their temp sensors. My first one was KTY 84-130. For my second order, I requested a 10K NTC but they installed a 100K NTC. I had to swap it out for a 10K NTC so it worked with my eBay temp display. The Cycle Analys works with linear sensors as well: https://endless...

I'm finally doing it. I've been running hub motors since my first e-grin but I have never done a mid-drive. I like the idea of the occasional ride in the snow so I've also been looking into fat bikes. Here is what I recently acquired: IMG_20190901_190626_small.jpg IMG_20190901_190615_small.jpg IMG_2...
