I can offer you my experience with the ICAN P1 which I ride as a trail bike. Regarding Ican P9, per ICAN it's considered their enduro bike. That may fit your needs compared to the P1. If I were to do it all over again, I would've gone with the P9. More updated geo, and also the P9 is compatible with metric sized shocks (newer type of rear shock sizing since 2017) and piggy-back reservoir shocks. For the P1 frame there isn't enough space for a piggyback reservoir shock once it's fully compressed. Just has compatibility for more up modern shocks
My ICAN P1 frame is a medium, I have a 150mm fork (44mm offset), and a 135mm rear shock. I have 27.5'' wheels and 170mm cranks on there. I've done about 35 rides on it with about 375 miles on it.
The type of features I ride include climbing over some roots about 1ft or less in height, small drops 2ft or less, ramp/rock drops (about 3ft-4ft drops), small to medium sized jumps. I have not taken it to the bike park, but been wanting to take it there as I've never been! I used to ride an XC bike, and just got the ICAN P1 trail last July 2021. From my experience so far, the bottom bracket height hasn't really been much of an issue. One part I remember where you'll definitely have pedal strike is climbing over 1ft high tree roots. I remember I would have to time my pedal stroke just right and lift my back wheel to avoid pedal striking the root. If you were to pedal over it, you'll definitely strike pedal on root
Overall, I've have so much joy with my ICAN P1 frame on the 27.5'' wheels and I definitely felt like it was worth the purchase for me thus far! And it's just been about 1 year since purchase
Hope this helps!
