Supercharger gates belt drive vario drive speed increase

[Pontylad]

Looking for ideas in getting an extra gear as I’m peddling like mad at over 20 mph.....can I increase or decrease the gates sprocket front or rear?
I have a 28 tooth rear one there are loads about but which type do I need to suit my cvt?
any ideas please?

I believe it’s 2018 model with the Bosch performance CX motor

Interesting, I don’t have those problems , but different bike.
2021 Charger 3, HS Vario, Average Cadence 55, no difficulty with average speeds of 18 mph, top speed 27.5. Flat Florida though.

That's because you have the HS (high speed). The OPs bike doesn't appear to be the HS version, so it will be geared differently in addition to the motor being a slower speed version.

Be interested in knowing what the gearing is on a HS version as I believe the motor is the same? Mine has a 22 tooth front and a 28 tooth rear. It looks easier to change the front one? Will have a look over the weekend.
Thanks to everyone so far.

The motor isn't the same, Bosch makes a Speed model that goes up to 28 mph, while the rest go up to 20. Not sure on the gearing since I don't have one.

The motor: Powerful drive for eBikes

The mid-motor supports the eBike from gently to powerfully. The Bosch eBike drive is optimally tuned thanks to a precise sensor concept, allowing a natural riding sensation and riding fun.

I reference Jesper who has some ideas on how to ensure Vario is set for high speed settings.
