Yes, it sounds like you are not liking the gearing, and describing the difference between spinning vs mashing. I'm assuming the cadence is off for you or you prefer the mashing which can be frustrating when you only have one gear.

​​​​​If the gearing of the SE was at a nice cadence for you then you would want to replicate the setup from that. You would want to know the front chainring tooth count, the rear sprocket tooth count and, to a lesser degree, the crank arm length. Match those up and you should be good to go.

It begs the question though, why not just stick with the SE?

*edit* If you want to make it harder to pedal (i.e. require more mashing) then you will either want to increase the tooth count on the front and/or decrease the tooth count in the rear.
