Lake District - Which Bike?

I'm off to the Lake District in a few weeks and plan on doing a bit of riding while I'm there. I'm planning on doing the Borrowdale Bash, a Helvellyn loop and possibly one or two other rides depending on how much free time I have.

I'll be taking my e-bike with me, a Trek Rail, as it'll be ideal to get out on if I'm not feeling too fit any day.

I've also got a choice of two other bikes to take with me, a 120mm travel Epic or a 150mm trail bike. Which one would you take if you were heading up that way?
