Greyborg Cromotor Hubzilla motors, Sold Out

Do you think that it would be ok if I faced off about 2-4mm of the threaded portion of freewheel side so I don't have to jam washers in And avoid flexing my frame open?

I dont think that would be an issue as long as your freewheel wasnt very thick. All my 16 tooth fw's are about flush with the end of the threads and still need a washer.

Today I tested a freewheel washer with a Dicta freewheel on my Cromotor which is from the last batch, purchased in December. I found that the freewheel was touching a shoulder on the motor, and that it is very nearly flush with the end of the threaded portion. So no spacer is needed on mine. I thought a spacer was needed but it turns out that was at a slightly larger diameter, and the shoulder was already contacting the freewheel.

It may be different with the new batch of motors, but on mine there is no value in trimming the threaded portion as the freewheel is already just slightly wider and sticks out a fraction of a mm beyond the threads.

Hi zombiess, I am going send it out money for 2 motors tomorrow once I recieve the money from my friend.

[Sigma]

Hey, I've sent you an email 2 days ago about ordering a motor after you sent that email, still haven't heard anything back yet :S, sorry you must be busy with all of this. Just wanted to make sure you got my email.

[zombiess]

Replied to everyone tonight and sent invoices for those who contacted me.

[Sigma]

Thx got your email/invoice and paid.

Yay... Do I need brass washers for the bicycle eyelets if I'm using 13-14g spokes?

It's going to depend on the spoke head size. The holes were drilled to accommodate up to 12 gauge spokes. A 13/14 is probably OK, but I'm not a wheel builder so I can't say yes for sure.

[zombiess]

I'm waiting on hardware to show up to include with the motors. Just found out it should be here today or tomorrow. Current paid motor orders should ship out on Monday if that is the case. I will send tracking numbers to you when they ship.

I have the first generation cromotor, so im not sure if the holes are the same size. But in my cromotors even the 12g spoke that I got for John Holmes would need washers.

[hillzofvalp]

but do your holes look like one of these:

Hi I was wondering where can I purchase one of these motors and is it possible to ship to Australia cheers. oh and if also if the kelly KHB12301,24-120V,300A,Opto BLDC Controller/With Regen would be up to the task to power the beast cheers.

Ok so critalyte 54xx vs hubzilla?

Is that vs a 53xx or 54xx?

Last year I tried to setup a 144v Cromotor vs 5403 comparison test using identical batts, controllers, and Norco A-Lines - but I couldn't get the Cro in a speed wind that would make it worth my while. In the end the IIRC the 5403 winding ended up having a KV between that of a 5304 and a 5305, so the xlyte wasn't the speed wind I was looking for either, I should have asked for a 5402 (and I considered it). Theres a thread on it somewhere.

I dont think that comparing a 10kg motor to a 15kg motor is fair... but imagine what a bigger (1.5 times bigger) cromotor with the right Kv would do to a 5403/02?

those videos he posted make me nervous about what I'm getting into. I was thinking about getting an 18FET but now i think I should stick with 12 FETs for my 29er.. what do you think?

i ll say it again... 18fet 4110 is the mininum to wake a cromotor!

[ZOMGVTEK]

18 FET 4110, or 24 FET 4115 would be the smallest I would recommend. The route I would take is 24 FET 4110.

[hillzofvalp]

really?...

I am trying to understand the difference between a 12FET controller with beefed traces putting out the programmed 100A phase and 80A battery current and an 18FET with the same settings. So the 12FET will run a little warmer but is there really a performance benefit?

[ZOMGVTEK]

...You plan on running a Cromotor at 100 phase amps? Yeah, a 12 FET would do the job there no problem.

Whats the appeal of such a big and heavy motor if you're not going to run much power?

[hillzofvalp]

Well I was thinking up to 150A.. But I think I read in this thread that the thing is hard to control even at 80 phase amps!

[zombiess]

Pussycat or monster its your choice and is based on your wheel size, battery volts, amps and phase amps.

With a 29er id suggest an 18 fet minimum. The videos of my bike just illustrate what it can do if you build for pure performance. With 29" wheels your bike will be waaay tamer than mine because you will lose a lot of torque to the ground due to the big wheels. Almost all of my riding is done under 2500 watts. I just like having the option to get crazy if i want to.

Advantage of 18 vs 12 fet is more the 18fet can safely output more amps. Im guessing you should keep you setup below 100v fully and then program it accordingly. I can help you by suggesting settings.

Even on a tame setup this motor will work great, particularly if you are after torque and with a 29er thats exactly what you need. If i let you ride my bike at 80 phase amps you might think it was broken because it wouldnt be anything close to the videos i posted. The controller you use makes a difference somewhat as well. All my stuff is modded and there is a difference between the old eb2xx controllers and the newer eb3xx ones.Both work great just differences in phase amp settings it seems, ive posted about this and have received no answers.

Zombiess, Thanks for the UPS tracking and I am looking forward hand of the cromotors even looking forward to be kick my butt during the riding!

Again thanks Jeremy!
