Hello awawa212,
welcome to Stridaforum!
Good question…it should be high enough, but as low as possible.
Ok, that does not help much, what does Mark Sanders mean:
From “Tips from Mark.pdf”, available via www.strida.com/en/download/
(Please read point 7. and 8. yourself, copy and paste does not work in this file!)
There is also a (maybe) helpful drawing on page 21 of the STRIDA manual-0617 revised.pdf
Surely you’ve meant 15 mm, I believe that is a bit too much.
Please note that the bottom bracket can be mounted in two ways, the pic below could be misleading:
(From this post 18" Wheel Upgrade: not that easy…)
All you need is a Ø 60 mm hook spanner (or an adjustable hook spanner of correct size).
I mean the correct steps for the belt tensioning procedure should be that:
- Loosen the big groove nut
- Loosen the belt tension bolt
- Adjust belt tension
- Tighten belt tension bolt
- Tighten groove nut
- Check belt tension
Maybe also of interest:

Did anybody notice that the belt tension of a folded Strida is NOT equal to that of an unfolded?
(Never adjust belt tension on a folded Strida!)
