How does dynamo hub feel at hand? I am 100% new to the dynamo world, and after unpacking it I was surprised how it behaves. I already googled and found out that some of my worries are &quot;normal&quot;, but for some of the issues observed I didn't find explanation (or &quot;it is normal&quot; confirmation).
I am talking about just hub, I didn't build a wheel yet. I am holding/squeezing axle nuts at one hand, and try to turn hub body with the other.
When I hold hub at hand and try to turn it there is a lot of friction, there are distinct points (some like stop points) where hub feels click-in (there is not audible click). Far, far analogy but it resembles the rear hub somewhat -- there is also some friction and there are also some special points.
Friction in dynamo hub I have is much greater. Gathering from all &quot;it is normal&quot; I take my hub is not broken. Yet.

But there is more -- the rear hub movement is predictable, I turn it by hand, the hub has no inertia so it stays exactly when I stop turning it, in other words any point/angle is valid point/angle. With dynamo hub if I am less than midway between points it bounces back by itself. So there are only X designated points/angles at which it can rest. And as for friction -- forward turning is hard, turning it backward is even harder (at first I thought it is not possible at all).
So my question is -- is this &quot;more&quot; section above normal as well, or those are odd even in dynamo-hubs world and I probably have broken hub (or terrible quality one)?
Remember a dynamo hub has a small electric generator inside of it. What you are feeling when you turn the shaft is the interaction between the magnets and wires in the the generator creating peaks of torque on the shaft.
