When the magnets explode they totally came off in my case. Also if you get it hot enough to remove magnets they should be at least partially demagnetized. That could be a defect.

The case was also extremely hot every time I blew magnets. You can't keep your hand there.

OK, you have a 12v system with a DC motor (or maybe 24v, if the two groups of 2 series 6v batteries are combined in series). You can tell for sure that each pair of 2 batteries is combined in series for 12V. DC motors don't need fancy controllers and in fact you can just slam the power on / off with...

So the tabs are welded to the batteries, but attached with "conductive paste" and by tape compression between stages on the side of the pack where visible? Looks pretty stable, really. Zero used to use a compression fit for their battery conductors about 10 years ago. It can work if you do...

That's pretty cool I would buy it for my collection at a price like that if I was local.

There's something worse than this?

At least it's not General Butt-Naked and his army of cannibals.

Just to be clear, this is an actual person who had an (sort of) actual cannibal army:

cyclone 3000

Think real hard about this because the cyclone 3000 in my opinion sucks more than twice as hard as the twice as expensive X1. The X1 not only is lighter and more powerful the build quality of the entire assembly is much higher. The stock controller is also better.

I used to pour beer on my hot hub motor.

What were the circumstances that led to you always riding around with a bunch of beer?? I assume the beer joined the bike before it was thought to be used as coolant.

Hey guys...DID YOU KNOW THERE IS A BACDOOR APP FOR PC that works offline, doesn't need a login, and is much easier to use and more full featured than the stupid app which is basically for people without working brains (or working PCs). Do you want a copy of the PC app? Please inquire via PM. Also a ...

ASI controller works great on some motors and the throttle can be set to have as little delay as you want. This motor it does not work great with for fast response. Go ahead and try a fast torque based throttle on ASI with the X1 lmao it will be so unreliable and shitty it's not even rideable. And C...

See if you can get the BAC2000 datasheet that was publicly up on grin's website for a while. It has a much better pinout with more info. The pinout for the 2k/4k/8k is all the same. I tried one of those foreign pinouts first and then when I compared to ASI's diagram it wasn't even the same. I have a...

May I suggest that you separate your two goals: 1) buy the best batteries made in china 2) make dedicated efforts at charity or contributing to your community Reasoning: They don't really make lithium batteries in the US and you won't find anything production that's cutting edge and certainly not fo...

Do you guys think this motor kit would work? I assume the ASI BAC800 controller would be the best choice from what I see.. No, the ASI X1 kits are all used either by kind, gentle, pedal spinning folks who don't mind the slow startup or by morons who don't use the power and don't ride hard, so don't...

@ flat tire: I don’t get it, don’t you use temp sensor and overtemp protection? Or wasn’t that enough to keep the cycs from bursting? Yes that would have been a good idea but the main aggravation was thermal limits butting into my riding not having to buy new motors. Overtemp wouldn't have fixed th...

I'm not sure what the actual purpose of the steel sleeve is because it certainly doesn't serve much purpose to retain the magnets even though CYC has marketed it that way. Take apart a motor and see for yourself. Apparently the real difference between gen1 and 2 was change of the adhesive or bonding...

OK show us your calculations where you prove that even a bicycle chain will break under your application and I will show you that you are WRONG.

Seriously go on show me the numbers.

relatively light motors OK so what lightweight high power hub motor do you suggest someone use to make a ludicrously fast (80 mph+) unicycle? Seriously though, because I'm thinking about how to do this with readily available ebike components that don't cost a fortune. That basically leaves the usua...

This motor is a lot of fun for wheelies. It will easily pop you up at low RPM, but doesn't make enough power to carry out power wheelies for more than a second. So you have to reach for unicycle mode right away with that front wheel really high to carry on a wheelie.

The CYC will be better than bafang and bosch for sure. It is a good mid drive. I just don't like the misleading advertising on power levels. Yeah, I want a drive that can take more power. But the LR looks crappier than the CYC even if it makes more power. I like the size, weight, and level of engine...

A 273 motor isn't for going fast, they're for pushing heavier loads.

Yeah whatever I guess you live in a world where big rims don't exist. Actually if you're in CR that's probably true. Anyway how about a 29er, or better yet, 36er 273?

Damn, what failed in these motors? I thought the potting would save them. Lets see some pics! Potting won't save the motors from thermal damage it mostly protects the windings from mechanical damage and to some extent conducts heat. I love the potting it is great. I have pictures somewhere. When th...

Gen2 is not 5000 watts that's just frocking bullshit. Sure, it will do 5000 watts for an extremely short period of time and the motor will limit power (or grenade if you don't have that setup). Gen2 motor is almost exactly the same as gen1, FYI. It just has a more reliable magnet attachment (but not...

I'm not sure what all the complaints are about.

Stock controller doesn't respond fast enough for racing where you are constantly on / off throttle and need instant response.

First you need to figure out exactly how much battery capacity you want. To figure this out, consider HOW FAR you want to go at WHAT SPEEDS under WHICH CONDITIONS, including ELEVATION. We can tell you which battery is a good match for that riding.

2 strokes are actually quieter than 4 strokes at any distance cuz the emission spectrum is higher frequency duh everyone knows that. Less power, no resonant (bell, basically) chamber, muffling airbox and big muffler are the tickets to making a quiet combustion engine. You're asking some really stran...

If you take a serious attitude that it's a mobility device and have an even remotely legitimate mobility-related complaint probably up to and maybe including "I can't walk 60 miles in 2 hours" you should be OK with the law. In fact cop brains will mostly think "dumb ass bicyclist, not...
