Re: Bought a battery from Luna. Might be a dud

I bought a 72v 14.5ah Panasonic pf battery. Went to plug it into the bike and noticed the xt-90 was wired backwards. So I got the soldering gun out and installed it correctly. IDK buddy any chance it was correct when they sent it and you switched it incorrectly? It doesn't sound like you tried it b...

I'm STUMPED! Help Me Please! BBSHD Broken

I have NO clue what is going on i successfully rode about 400 miles with my BBSHD and a 48v battery. I got a 52v battery and rode another 80+ miles and then out of nowhere i powered up the bike and this god awful sound, weird vibration and such. I have been getting more agressive with my rides going...

Mündawg's Vlog -Finally Got Some Videos Up

Hey it's been a while, been really busy building/upgrading the bike. Haven't been posting, or even reading, all too much. I hesitate to call this a "Vlog" since i don't narrate much or talk about parts. I might make longer ones if ya'll are into that. I could show my setup. These are from my instagr...

Re: E grom

Why would you (anyone i guess) add a second front wheel, which adds a bunch of complexity to the design of these motor machines? If leaning is the goal doesn't one front wheel fit the bill? ie a motorcycle?
I'm genuinely curious.

Re: Overjuicing a mid drive motor?

I don't think mid drives are as easy to overvolt than say DD hub motors. I know the BBSD can handle 52v with stock controller. But at least you can upgrade the mosfets to run some more amps as well. 52v x 40A = 2,080 watts of power. That's a lot to go through the bike drive chain imo. This is where ...

Re: How to mount a bottle-mount battery.

My bottle pack battery didn't line up as well. But i slid the whole unit up the frame and used the lower hole on the battery and the upper hole on the bottle mount. Then i used metal hose clamps with some rubber under it to clamp the top part of the bottle battery on. It works so far.

Re: No forks or rear shock needed with new wheels

I can see how this would be very beneficial to a wheel chair to ease going over steps and curbs etc. But i worry about cornering and strength at high speeds and with high torque. Also, 2,000$!!!!!!!!!!! for a pair!!! That's the price of my WHOLE EBIKE SETUP!!!!! No way in hell i'd pay that much for ...

Re: UrbanX Smart Electric Wheel

I've seen a few of those all in one battery motor controller setups. I think they have potential to catch on in coastal cites, flat and hot places. I can't imagine it's got much range or power. But sometimes more isn't better.

i am not surprised that the controller burnt out. Those things need to be ventilated.

Re: Water cooled ebike battery

The purpouse of having water cooling for me is not to avoid extreme temperatures, but to maintain room temperature of batteries while standby, etc. To extend their lifetime, or do you guys think its not necessary? Will not make any significant impact? I am confused by your intent. By "room temp" do...

Re: Looking for some guidedence, commuter bike & motor

Just no need for the complications of a mid drive and the BBS02 is not a 30mph motor. I was talking about the BBSHD and it is definitely a 30MPH motor. When powered with the right battery. I have no exp with the BBS02. I am curious tho what you mean by the complications of a mid drive? After instal...

Are you sure that is a Bafang? They usually have Bafang labeled somewhere on the motor. If it's only 350W i would assume it was the BBS01 but i am no expert

Re: Bicycle for Bafang 350W

Personally i think the commuter with fatter tires would be more than fine for just a 350W. If you were doing the 1500W mid drive i would suggest the MTB. Flat commuting choose the most comfortable, I hate the MTB position for street riding. Why fatter tires? To handle the pressure that comes with t...

That's 500A - 2000A per volt. 100KW at 50V. What's the catch here.
Ridiculously high current i would guess
