Is it possble to covert 26x4 to 3 onch tire and rim combo

[PCeBiker]

I just sent them another asking about a 29 as I don't see anything wider than 24mm width id on their website.

What about asking them about a 27.5" rim?

Maybe they know of a better option than what's on my ebike?

That's the rabbit I jumped in to and didn't find anything.

Comparing the 27.5 x 2.3 to the 29 x 4, the height difference didn't look to be more than a little over an inch, and figure to lose 3/4" height on the bike. Interestingly, the pedal height was 1" higher on the 26x4 tired bike, so dropping to the 27.5 is going to put the pedal height in the range of the other bikes and make the ground reach easier. The way it is now the seat has to be way too high to make pedaling normal and touching the ground is tip toe. Dropping it down an inch isn't going to hurt anything.

This pic makes the closer tire appear larger.
