Re: GNG / CYC X1 Pro 3000w

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.

Re: What is this Boat?

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...

Re: What u think of this?! Tape connections. Wish me luck

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 it right....

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.

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...

Re: GNG / CYC X1 Pro 3000w

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.

But the LR looks crappier than the CYC even if it makes more power. I like the size, weight, and level of engine...

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...

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