Yeah, but it is huge. And heavy. Not everybody wants that. The Photon, on the other hand...

There is something off here. In low gear (34,52) on my bike, and very much higher grade, I could run all day without approaching the temps you are seeing. Similar cadence. I posted a video a few pages (26 Feb) back showing this...

Photon. Nothing else comes close. Especially for modern MTBs, which none of the Bafangs, Tosevens and Tongshens etc will fit. But pay attention to its intended use - as a DIY equivalent to OTS ebikes (and especially e-MTB) which are expensive, low power and low torque. CYC have explicitly...

I find mine to be smooth but over a very small initial range, after that it doesn't vary so much and is pretty much full on. It works fine, though - on mine I usually roll my thumb against it, rather than pulling on the blade directly. I don't ride much with throttle partially used, tend to use...

There was a recent firmware update, do you have it?

I'm almost certainly older - I often just put a ruler next to what I want to measure then take a photo with my phone then zoom in :)

Count 10 or 20 or more and measure that, then divide- most accurate way of doing it anyway. What is the outer diameter of the core?

It might take a while for that mod to travel down the supply chain, I guess buying direct from CYC gets you the latest version.

As a matter of interest, is your left bearing cup the same as the one Rikus describes in his recent video (a few posts back?). CYC added an O ring inboard of the threaded portion of the bearing cup to improve watertightness. The O ring seals between the bearing cup shaft and the corresponding...

Well, looks like they fixed it. I know I'm not the only one with the original detail. it causes all kinds of issues, including making it more difficult to set the right preload, wearing the shaft and shield bushing, and destroying the bearings. Thanks for update, that is really useful information.

That's it, it has a raised edge on the back that grinds away at the bearing cup and makes the bearing feel nasty. It has worn the face of the cup so much that there is a groove caused by the shield - the finish is supposed to be the same across the entire face of the bearing cup. I had hoped...

Mine was really tight, didn't move even when I was pressing the shield out.

Its the shield that covers the outer face of the left BB shaft bearing. The split ring that screws on the shaft and is then clamped in place with a hex socket head screw sits immediately against it.

While you have the shaft out, can you measure the outer diameter of the plastic bearing shield? I'm expecting it to be either 36.5mm or 39.7mm. I suspect that early motors were shipped with an incorrect shield and wondered if CYC had corrected this for later shipments. CYC would either have had...

Not a great way of doing this. The puller may not use the full depth of the thread in the crank and to be safe you need to use as much as possible - and being aluminium is easily stripped. Ask me how I know. Also some of the cheaper pullers may not have accurate threads anyway. That aluminium...
