Congrats on the new bike!
Sirrus X is a fun bike.
I recently bought a 4, after I was unable to find a 2 or a 3 in my sizing.
Then I bought my son another 4 and I bought two more 3s for my younger sons . . . and then I had to figure out how to rack 4 bikes on my car!
We love them so far, and I hope you do too.
