Noise level is roughly the same as the internal controller so its relatively quiet. Perhaps only slightly louder from the higher RPMsschwibsi wrote:How is the noise level compared to the stock controller?
I combined a VESC with my BBS02 and I can't get it to quiet down. It's much louder than the stock controller, even in FOC mode.

You can't pedal that bike, right? It's just like a motorcycle then.

The high voltage cancels out the main benefits it had at stock voltage of low noise and compact internal controller and it will never be as power full as the C3000w that does 6.5kw peak .
You loose the compact clean internal controller, LOW rpm and low noise and easily pedable crank cadence that goes with the standard voltage . And it still has less power than the c3000w and you will most likely swish cheese the plastic gears like karl did so why bother ? and for all that you get this bad chainline which is a design fail as they have the gear reduction where the chainwheels are supposed to be?? The c3000w has better chain line and also you can run a 2nd lower gear that the BBSHD cannot ad the gear reduction is in that spot.

He has racked up almost 3000 miles, and he sends up to 6500 watts (90A @ 72V) through his system, so I don't think the longevity of the Cyclone 3000 setup is really much of an issue.

I'm building up my 72 volt battery once I get some more nickel strip material. But I need to fix the chain line. I had to space out the drive from my bottom bracket in order to clear the the chain stay and some bits from the rear suspension. This really messes with the chain line.
