Long term feedback: No belt problems since the repair service in Vienna.
As I use my Strida about 11 km per working day - This means about 1.000+ km.

Now I'll have a problem with my rear break, but this is another story and yet to be investigated.

For comparison, stridahd's freewheel next to a brand new one:

Wow, it wears very quickly (only 1000km!). Ming Cycles should definitely improve the freewheel design: better surface hardness and better sealing/friction of the bearings.

Is it a visual effect or is the outside diameter of the new freewheel really bigger than the OD of the used one (look at the size of the flanges)? I
f this is the case then the number of teeth is not similar :?:

No Bietrume, that's a misunderstanding...sorry, my fault...

The above shown freewheel is stridahd's first one, the one we've changed together with Mike.

But, in fact, 3.000 km are also not that much...

Indeed, yes, here's a similar pic, taken 90° to the left of the cam position before:

Interesting photographs :)

You also have to add the fact that I am not lightweight and I used it throughout two winters without much cleaning.

PS: I fixed my break problem for now. The brake pads were worn and I had to adjust them. However I guess I will need some new within this year. Any suggestions for a shop with reasonable prices?

After 2 years riding in the snow and rain the belt also twisted and torn.
Initially, I though it was due to excessive torque, so I could manage by avoiding steep slopes.
Now I need to replace my broken belt and it seems that I need to adjust the tension after getting a new belt.
I don't know exactly how to do this, additionally my rear disk is also bent.

Well, beginning at the brake rotor...
Unfortunately can a common brake rotor (without heavy mods) not be used, you will need an original brake disc.
At this opportunity to order spare parts you might also take a closer look at the snubber bearing, the 338 part (magnet spacer) and of course the freewheel.
The rear rotor is clamped by the freewheel, a special tool Tis required to remove it - do you have such thing?
As always, I'd recommend the purchase of a hook key A for proper belt tensioning
For convenient belt changing you might use the step 13 of this thread.
(There should be also a few hints for belt, snubber and rear brake caliper un/remounting :wink: )

Did you already check the local parts availability?
