Modern bike tech design seems to suffer more and more from a disease i call CADiosis - far too complicated parts for what they are and far too many tinny little details all over the place.
It is nice to see shimano started using sealed bearings. Standard sizes are easy to source. What affordable hub do you recommend for ebike? 148 boost, HG body.
No idea - not sure which hubs are designed to take the extra weight and torque (if any). Shimano Deore (the original, not the Deore XT) used to be their most durable/robust set that doesn't cost an arm and a leg, but they've switched to the cartridge bearings and design similar to the hub shown in the video (with a hyperglide mounting option AFAIK).
CUES is supposed to be suitable for e-bikes. I would simply go the route of the least money: 5 or less row freewheel. At least the chain will be far sturdier.
Since i've invested in press bearing and puller i can't imagine servicing cup and cone/standard shimano bearing hubs. I hate messing with bearing balls and setting preload.
I've get it about teeth of this freehub, but definitely miss about support on a shaft. I've seen two bearings in body of hub and two in a actual freewheel part. Or problem is that there was fill bearings and than was installed cartlidge bearings so actual fill bearings don't give enough support in stock part?
Good question - that's something that even some great mechanics don't understand. I answered it on the forum: www.bikegremlin.net/threads/shimano-fh-mt410-b-12-speed-microspline-freehub-design-discussion.341/
I have a 6 speed freewheel,the thing is that under load especially uphill the mountain it skips.I think it's not about derailleur or worn chain,when I serviced bearings of a freewheel I noticed the pawls come back slowly after being pressed.Is it possible to strengthen that spring ring somehow or just replace a freewheel
Cup and cone bearing freehubs have a better bearing support for the axle. Freehub ratchet and pawls - that has been made with 3 or 4 pawls for decades as far as I know.
Typically yes. Mainly for the simple reason that the engagement diameter is much bigger than in the case of a freehub. The forces engaging are therefore proportionally smaller. Additionally they are made from simply steel instead of some fancy aluminium compound. However those days the production quality of freewheels tend to be much lower and you may draw one that is really shabby.
Bravo relja, fantastican si, za sve preporuke, ima li sanse da te kontatiram, Srbija nam je u problemu sa bike serviserima ali skroz!

Finally a little stuffing and grease on the fingers :)

@@BikeGremlinUS Well said. If any. I do not have any objections to current models. As long as they are repairable and not expensive to fix.
Mid drive or back wheel motor?

@@rosomak8244 Mid drive. Back wheel motor does not overload freehub body.
I think it would be cool to see you guys do the Cape Epic at some point
I hate loud hubs. I wish the Onyx silent hubs were affordable.
Though heavier this is a better design than my XT hub which has been making weird noises.

Please use the bikegremlin.net forum for any technical questions.
Do you think a traditional free hub is stronger?

Pozdrav, imam promblem sa zadnjim točkom kada stegnem osovinu otvara mi se točak. Šta bi moglo biti
Za sva tehnička pitanja bih uputio na bikegremlin.net forum.
Are you from Bosnia or Croatia? I can hear it on your accent
Worse!

It’s all on my channel’s about page.

I was given six of these by a client for payment of completed repairs .
