Ultimately, you know that you'd want more than one bike.
Keep the current full sized bike and get the BF
PR to supplement.
I have tri-bike and small wheeled bikes, for the fastest of rides, fast group rides and any ride that requires the speed/efficiency, I will use my tri-bike.
For travel, multi modal commute or just proving to ppl that a small bike can also make it (eg. 200km brevet), I use the Tyrell IVE.
