Surface604 Shred - Upgrade cassette from SRAM 12-34T?

Does anyone know if it is possible to have a higher gear cassette on the 2020 Shred as I would like a higher gear so I can go faster on downhills or flat ground? I believe the 2020 Shred has a SRAM 12-34T. Or would it be better to have a larger front crank? Any advice or input would be appreciated.

It's so hard to see from the photos how much more space you have.

Ok, I just realized something.. the chainring is placed inside the crank.
Can you place the chainring outside the crank?
(just like multi-speed front crank, or even chainring cover?)

If you could, you could probably have more space.
I don't know if that would affect the smoothness of shifting though, because of bent chain line.

Are you sure you have 12T-34T?
It says you have 11T-34T.

So looks like stock Shred has 38T.

38T is indeed, a bit small.
Looks like it has BCD104, and there are a few options.

You can go up to 52T.
52T would be a standard size for a Class 3 ebike. Juiced CrossCurrent for example, has 52T as stock.
