Re: BBSHD or Cyclone 3kW?

I don't think the co-axle and standard 3Kw have much in common in terms of gearbox unless I'm quite mistaken. 10:1 would be extremely tall gearing for the 3kw. I'd stall it on most hills I'm riding, but I've only got 40a to play with. Perhaps 60a could pull it. The coaxial is a 4kw cyclone repacked...

Re: BBSHD or Cyclone 3kW?

So you are running direct from the gearbox output to the rear wheel? I've got the 40a controller but if the motor can take it I may shunt mod it for ~60a so I can pull a bit taller gear. My controller also doesn't seem to have a high speed switch wire like some do, or else the colors are different ...

Re: BBSHD or Cyclone 3kW?

You're total reduction is from the gearbox output correct? My current setup of 1:6, 14:44, 44:32 puts total reduction at ~13.7:1 which is just barely possible using 219 sprockets direct into a 3spd IGH. I think the motor could handle a taller gear in my setup but the chain certain can't. My reducti...

Re: BBSHD or Cyclone 3kW?

Well crap, I was basing a future build on it being 5:1 which would just barely allow direct drive to an IGH (12.5:1 total reduction). As for chain life I'd go bigger on the rear every time for increased teeth engaged. The only time I've broken a cyclone chain was with a smaller front running to a 1...

Re: BBSHD or Cyclone 3kW?

I believe the 3Kw cyclone is 5:1 and either a 13t or 14t front to 44t. Running a smaller chain ring puts more torque into the chain, better to upsize on the rear sprocket and definitely not try to peddle along. It is 6:1. https://endless-sphere.com/forums/viewtopic.php?f=28&t=69867&start=200#p11477...

Re: BBSHD or Cyclone 3kW?

Is this true? So likely (46'ish/12) * max500 rpms, at 52V. So roughly 125 max RPMs, given a 46t front chainring. Correct? Thanks Yes, ~130rpm. Remember, the higher rpm for the given wattage, the lower the torque on the chain, which is a good thing. So I would go with the smallest chainring possible.

Sorry to resurrect an old thread, what is the cadence range of the cyclone 3000? I can't find a good answer to this question. I've seen the BBSHD said to max out at 150 rpms at ~52V (true?), BBS02 at 120 rpms, but can't find same spec for cyclone. Thanks!! Does anyone have a fancy curve like Grin h...

Cyclone 3000 throttle response with stock controller is very un-smooth. Not suitable for off road, the bike can throw you off of it if you'll ride while standing. Is there a solution? Another controller maybe? Tried Phase runner, but it can't read the encoder, and not sure if will improve the throt...

Three Phase Power Calculation
Three Phase Voltage = 60 V
Current = 800 A, Power Factor = 0.95
That explains it, the 32kW is not calculated with battery voltage and amps of that setup.

Re: Modded Sur ron Question

The story is the motor burned up after a while at 32kW. How they got 32kW out of the BAC 8000, I'm not sure, same with the 25R battery, but this is Luna so their numbers can be strange.

Well, ok. It will no be a Cyclone this time. Thanks for the heads up.
But I got a pic on the new Cyclone comming in mid Jan.
It looks very promising.
Got any specs? Looks like the 3kw with (finally) a proper mount.

90% of the bike vs car crash videos, they either go too fast or too close. Where are you going in such a hurry that you absolutely need to overtake moving cars? Was it worth it?

Hi guys
What is the maximum voltage you are running with the stock controller that came with the cyclone?
Rated 36-72V, but wondering if anyone has pushed it beyond 72V??
Caps are 80v on older ones, 100v on new ones. So no point pushing it past 72v nominal which will be 84v max already.

Re: Battery options - MJ1 vs GA

MJ1 Lasts longer up until 3A cont and is cheaper, GA hits harder and lasts longer at higher amps while being more expensive, GA probably also has a higher cycle life.

Re: Sur-Ron - New Mid drive Bike

Is that the original X Controller (with regen) or the new X Controller? Because with the original X Controller (at least) the top speed was definitely 20% faster, and it definitely feels ~20% more powerful. I don't think I would have noticed if it was only an increase of 3-5%. The test is a generic...
