Cube Hybrid Touring.....problems with chain guard

Hi all,
I've been pleased with my Cube ebikes.
The chain guard is not good enough, however, and I've removed them. (I have 7 bikes, which are my little Ebike rental fleet.)
Does anyone know the part details?
I'd like to buy a simple chain wheel guard, because, at the moment, the chain wheel is fully exposed.
The chain wheel has the five, not four, screw holes, which are about 76mm apart from each other.
I haven't been able to find a manufacturer's mark, on the chain wheel.
If anyone knows how to find out which chain guard to buy, I'd love to know.
A very simple little disc would be fine.
Ben

Thes chain ring guards are easy to find, simple to install and not very expensive. You need to keep track of three critical measurements when making your selection:

1. BCD (bolt circle diameter) - usually 104 on Bosch equipped ebikes
2. Number of bolts - usually 4 on Bosch equipped bikes
3. Number of teeth in the chain ring.

You can buy these quite inexpensively on ebay.

Thanks Alaskan.....
I'll use those pointers, and count the teeth.
Not sure what BCD is.....
The chain wheel has five holes, to take the little screws...
Thank you very much for replying.... it's good to find this forum!

BCD= Bolt Circle Diameter. Measure that and with the number of bolt holes (5) search for "chainring guard 5 bolt ___BCD (specify motor maker such as Bosch or Brose" or substitute chain guard for chainring.

You might try to look for a complete replacement chainring with integrated chain guard like this which would also require purchase of a chain ring spider
