Re: INFINEON CONTROLLERS FOR DUMMIES

I've found the 12 fet 3077 incredibly robust and programmed it to 100A battery and 250a phase, running a Cromotor v1 and then a MXUS 3k on a 14s, and used it in slow speed, high load conditions riding up 30% rock covered hill sides.

I'm sure you'll be fine bumping up the power a bit.

Re: E-S LMX 64 Bike Owners

The best solution for the problem would be a 20T+ pulley and a motor with more torque :wink: As it is now with only 7T engaged at such small diameter it is by far out of specs and it will always wear out quicker as you wish. I know your just taking a friendly jab madin. A larger pulley would of cou...

Re: Need Advice for High Powered Mid-Drive

#1: What's the best controller that I could buy that would allow me to comfortably run 14s on the Astro 3210 at 50-60 amps continuous? #2: How can I be sure that my Astro 3210 is 100% operational? What can I do to test this motor to make sure it wasn't damaged by the previous owner? #3: Am I stupid...

i ran all-in in mode 3 and had the chain come off four times in 30 minutes..
Seems like the chain has stretched and/or is dirty Eddy. How many k's on that chain?

The #219 on the LMX is also an unsealed chain and I think you run some muddy tracks, so it might be time for a fresh chain.

Re: E-S LMX 64 Bike Owners

But as far as the LMX you guys have, I don't think there is a better MTB design that can climb like your 64 can. Yah, the SurRon does offer a pedal kit, so does Vector Ebike for their vortex model, but realistically those things suck balls can't be pedaled for distance or un-assisted power like you...

Hey Brian, I was just flipping CD the business. We go way way back... so to speak. He got his Fighter about the same time I got my Bomber and we have been back and forth ever since.

Re: E-S LMX 64 Bike Owners

To anyone wondering what Brian and I are going on about, this is the climb neither of us has yet to be able to complete without stopping as yet. I came close on this attempt, only stopping the once at the hardest part. This is the sort of thing that's impossible on a hub bike. It should be possible...

Still yet to make it up the super gnarly rock garden hill without putting a foot down, but reckon it's doable with bike the calibre of the LMX.

Re: E-S LMX 64 Bike Owners

Just found the invoice, seems to be a 27.5, maybe the 2019 fork had a bit more clearance?

Re: E-S LMX 64 Bike Owners

Sweet build Briangv99. Happy with that fork? What size is it, 27.5" or 29"? I have only 3mm clearance between my fork brace and tire, which seems way to little. Would running a 180mm 29"er fork on this 27.5" bike change the ride characteristics? Hey Eddy, Adam sure had turned out a great bike, bigg...

Re: E-S LMX 64 Bike Owners

2 minute job CD, so worth experimenting. It will make the geometry slightly slacker (more stable) and turning more responsive with the bottom bracket sitting lower. Slight increase chance of pedal strikes

Re: E-S LMX 64 Bike Owners

Our sprokets are custom made in 7075-T6 because 14T is very small and not readyly available. If the sproket wear becomes a problem we will look into getting some stainless steel ones made. We had them sepcially made because 12mm wide is not standard and we wanted to integrate the flange into it. Ad...

Re: E-S LMX 64 Bike Owners

I wonder if LMX had them custom made though...Adam, can you let us know what the deal is? Looks like the sprocket is custom made by Adam and looking at the belt picture you posted, the profile appears to be Poly Chain GT, so the sprocket I posted early isn't suitable.

Any suggestions for where to source these? No off the shelf options that fit the spec, but a machine shop, like the one that produced your Fighter torque arms, could do a run from a CAD file.

Re: E-S LMX 64 Bike Owners

Its 8mm pitch, which is same as LMX, but profile may not be right?

It would need to be bored to 14mm, narrowed from 20mm to 12mm and a new keyway filed. All depends if the groove profile is right.

Re: E-S LMX 64 Bike Owners

Looks like you have an excessive wear on the motor pulley too. To reduce the excessive wear on the primary sprocket(and the belt itself) and belt skipping, it needs to be Bigger. ...or better yet, same size but made with steel Dug this one out of my parts collection, steel 14t IMG_20200330_153440_c...
