Hardseven 2.5 direct mount chainring

[Slymobi]

My current is a 38T direct mount that looks offset in someway that has a fitting with 28 teeth around and I've seen some SRAM and Kmc but both state Bosch where my motor is the Yamaha pw-st. Then I've seen loads of chainrings that have a total different fitting standard etc and then others that need a separate spider altogether, so I'm getting confused for the correct replacement.

Thanks in advance

You're correct it's a Direct Mount chain ring with 28 internal teeth (even though there's two types using that name ).

I don't know if you need to take chainline offset into consideration though

They are both the ones I seen but confused as states they are both Bosch. The haibike 2.5 is a Yamaha motor. Is it just me or is everything such a PITA when it comes to Haibike parts !

The only marking on the existing is the brand Miranda, no part number, sizes or anything. Go to the Miranda site and this chainring doesn't exist lol.

I have NO idea why the KMC Bosch Gen 4 ring fits but I've had 2 ( 34T and 38T ) since this issue and both still in great condition.
