I can't get past that tiny wheel... why... just why.

im going to retest this battery for a few cycles. i saw the mnke 26650 battery didnt like to run constantly without suffering a big mah loss after about 24 hrs? plus the mnke and p42a didnt like to be cycled without an extended break between charge/discharge cycles. in the numbers above you can see...

Does anyone know does the KT controller original software have the feature of power rollback, basically, when coming close to LVC it starts taking less power from the battery?

Best rear light is the largest one. Led tech has led to a lot of very tiny, but very bright, ultra lightweight flashers for road bikes. I see the flashing of course, but its still so small you have a very hard time judging where it is. Is it 50 feet away? Is it 50 yards away? It can be hard to say ...

2. Any ideas for unlocking/opening up the battery case for when the time comes? Easy, you can lockpick it. Get a cheap lockpick set, one that comes with sample see through lock. These battery locks are hilariously easy to open, on par with $5 cable locks. I promise you, from getting the package, yo...

Why not use the switch on your battery... Let the bms FETs switch the power... It's what they are there for.

The listing itself has no mention of tesla at all, what do you think?

This one does (same seller): https://tinyurl.com/yyfftcma
He also states they originally came from a "pack"

He is a straight up liar... Also from cali... Might be Eric from luna.

Eeb construction wise is bottom of the barrel mild steel. Unless it is the only way of meeting your requirements I would look elsewhere, even then, I would get a variant, like the vector frame for example.

I purchased a few 21700 cells from ebay seller tonycu41 https://tinyurl.com/y3yqexaz Not received them yet. Stated they are new from an unused 'pack', one year old. It's doubtful they came from a genuine Model 3 pack because the model 3 cells i've seen have a bare metal shell & recessed positive te...

Nice deathtrap build... What's the point of pouring time and money into it when the bike is junkyard material meant for light cruising in the first place? I was thinking it. Also, there's no way that thing goes 32mph with a 500W rated motor system. 32 km/h maybe, with a tailwind. Or if you drop it ...

Do we have an idea where they are with the backlog?

Can someone please help me with the username and password for the BacDoor app ive asked and cant get it You have to ask from your dealer. ASI knows how many people are logged in at a certain point and frown on one person giving it out for many, as it is easy to brick the controller with the app and...

I went this morning to decathlon and the guy did not advise at all to do so.. but in all honesty, she's going to use it for city commute, not offroad or so. One advice, don't give an ounce of consideration to the words coming from someone who wants to sell you something, will likely never see you a...

I was looking at geared motors for their smaller size, lighter weight and better hill climb for occasional climbing. Most direct drives i've seen are huge plates. Also their dd sets doesn't have waterproof connectors and battery integrated controller. Chamrider 500W MXUS XF15C has 52V 19,2Ah is 14S...

I got my order from chamrider. Xf19 1000w 48v 24ah https://m.aliexpress.com/item/4000838391101.html . Single speed freewheel for now. I already did a spin test in the air. Spun good, noise comparable to any mid drive (except bafang). Shook battery, nothing loose rattling. I will open the battery up ...

Thanks for the reply, I was kind of thinking along those lines but the mini seemed to have more mixed reviews in terms of overheating and such, though I guess it would be safe to say that at the power levels I plan on running it would be minimal The 500 watt gng kit also looks interesting and would...

So , will the cyclone be a total dog compared to the bafangs at a similar power level? I was happy with the performance of the 750 watt BBSO2, so if it is somewhat equal then it is fine. Thanks in advance, Chris Cyclone mini would be much closer. Cyclone 3000w can do about 1.6kw cont 3.5kw peak. Di...

The cells are unlikely to be rated even 10a max, but you will be drawing 10a+resistance losses from them, with the 48v battery, each cells sees 8a max. You may wish to check your calculations, I make it 5.5 amps max draw per cell for 14S4P & 4.4 amps max for 14S5P (+resistance in both cases). Yes t...

Also I got a tip that you could get kits cheaper directly from MXUS in Alibaba.

Bac855 would catch on fire at 90a battery. Please make the distinction so you don't give people the wrong impression. A yuyangking $70 square wave 80a controller is 210 phase amps 80a battery. Bac2000 is 223 phase amps 100a+ battery. Bac855 is 90 phase amps 40-45a battery. It is in a different leaug...

If it works with a cassette spline you can buy or get one made on ebay to convert from spline to bcd 64 or 104.

But that is a big workaround, just get a smaller chainring.
