Mid drive front freewheel mod.

Today I did the zip tie mod and it seems like it's working; it worked right away without any fiddling at all. FYI, the chain line is probably decent and I'm using a chain guide as stock Bafang chainring sometimes drops chain (in normal use, without this mod).

The one thing wasn't mentioned (or I didn't notice) is that bike becomes silent when coasting. It's good or not, I've no idea yet. When people hears the ratcheting sound they know something is coming, but my fat tires makes sound anyway.

My "Quanta" rear hub sometimes skips teeth and this can help it. If it'll continue to work like this.

I've been running this now for a few months and over 1k miles, been great! I would highly recommend this to anyone. Makes the shifts really quick and also the hub is constantly engaged so no more smashing the pawls or chain slap to worry about, just hit the throttle as hard as you want and go no need to baby the throttle from a start. Especially when you are running a 3.5kw bbshd like I am. I believe this also has helped not destroy my high engagement hub, before after 800 miles it was toast, had to go back to my old wheelset. When I did this I replaced the internals to see if it would keep it for being destroyed and so far so good!

I just ran across this video, looks very doable for a skilled diy'er with the proper tools.
Just give ya some idea's

After BBSHD torque destroying pawls on aforementioned Quanta hub, I switched to new chinese hub called "Taozik". It had 6 pawls so engaging better, and didn't have that skipping which Quanta hub had sometimes from the beginning, though rarely had some skipping.

I wasn't using this zip tie mod beause on stock chainring, it tends to derail the ring. But in Luna chainring, I think it never happened.

But... this time axle was broken, and for a few days I was riding with a broken axle. I was wondering where the creak is coming from, and I found it by coincident when I removed the wheel, thinking that freehub lockring was loose (it was looking loose). In fact it was looking like loose because of broken axle. I don't know if axle was broken because it had low quality, but I suspect so.

Anyway, now we (the country) cannot buy anything over 30 euros from AliExpress, I had to remove the ratchet ring in the first hub. I don't have a tool for it, I don't know which tool fits it, but I did it with a die grinder:

The result is OK I think. Maybe about 30% aluminum threads got destroyed but it'll probably hold the new ring I ordered. It have less teeth (36 against current 45), so engagement will be better (I suppose it have deeper teeth). By the way, I "fixed" remaining theads in the grinded area with broken ring, so it can turn almost easily.

Attached images show damaged ring, and the destructive removal of it.

Long story short: In my case, I probably have to use this "mid-drive front freewheel mod" to not have to change hubs or grind them frequently.
