Hi Dan. >>Is the movable bearing really supposed to be on the Non-drive side? Yes >>Are the threaded cups on the wrong sides? That seems like it would make way more sense. No, the drive side spacing is fixed so that the chainring is at a fixed distance from the frame. >>Do people using these on 68/7...

Is there an off the shelf sprocket that can mounted to the 6 bolt disc rotor holes? Or are the guys building these mid drives customizing motorcycle sprockets to fit on the hub side cover?

Looking good!

Keep up the good work,

I'm guessing the picture shows a 3D-printed polymer prototype.

...and that heat dissipation of such a small case is not enough for 1 KW continuous use, even if it was made from Aluminium.

I applied some grease to the back side of the brake pads, as was suggested to reduce the rear brake howling. It did change, but it did not solve the problem. I use Kevlar compound pads from Discobrakes (https://www.discobrakes.com/?s=0&t=0&) on all my bikes. They are silent and don't seem t...

Probably it's for mounting a front derailleur.

StinkyGoalieGuy, the Phaserunner controller has a new "virtual electronic freewheeling" feature which helps with the problem you are describing. Only 2 rides with it, but I like it very much. Avner. In addition to that, we've also changed some things around on the layout and added a few fe...

If you fit BBS to this frame in will severely compromise ground clearance.

Went on an extended ride yesterday and discovered a small issue with the electric freewheel feature. While standing stationary, if the bike rolls backwards then the electric freewheel activates. I guess it is triggered by any movement in the motor regardless of direction. I think it should only acti...

There have been a number of tweaks on the back-end that we are hoping will fix the random communication errors or other glitches that some people would experience during the autotune process, and we've also updated the error dialogs when they do show up to be much more informative. So if you are so...

Has anyone programmed one of them with Grins Phaserunner software?

Avner.

From what I know, The phaserunner is based on ASI's 2KW controller.
They also make 4KW and 8KW models.

If you measure the resistance between the phase wires, someone here could probably tell you which winding you have.

I don't think that the xt derailleur will work with 8 speed cassettes and chains.

Hey ferret, could you find the ditch your rear brake thread, and leave your opinion, especially tell us how pedaling is better with freewheel. Thanks, Cookie. Hi Cookie, all the ebikes I've built or rode had a freewheel incorporated, so I don't know how hard is it to turn the motor while pedaling. ...

Using the WUXING 108X (on the left side).
After running it stock for some time, I shortened the lever with a grinder to get less linear throw and more sensitivity.




Happy with it.

Avner.

Yes I did, The Astro standard motorshaft diameter is 3/8" (9.375mm). IIRC I bought sprockets with 8mm internal diameter (http://www.staton-inc.com/store/index.php?p=catalog&mode=catalog&parent=45&mid=0&search_in=all&search_str=&pg=2) and drilled them out to 3/8". Av...

Thanks guys!

I don't think there's a business case for selling it, much less making it a product. Not many diy people are interested in converting 150mm frames or retaining the disc brakes. Making an adapter cost around $250 (I had 2 versions made, one alloy and one steel). Add the price of the hub, long axle, f...

It depends on the exact location of the holes.

It may be counterintuitive, but a small hole is more likely to start a crack than a bigger hole.

Have you considered using rivnuts? They're what some frames use to mount water bottle cages.

Avner.

I run a similar setup in my Astral Rune build and had no brake contamination.
I'm using wax based chain lubes so the only risk is during application.

Avner.

How much machining on the hub itself? Can you share a picture of the adapter? I had to remove the boss that centers the rotor on the hub as well as modifying the end cap. I also replaced the hubs's axle to from a 150mm hub. Is there a standard thread-on bike Freewheel in there? If so, is the innerm...
