1) No just regular tires
2) Sometimes, it is harder than riding on the bull horns but not impossible
3) sure, I just need a step to get on/off
4) absolutely, once watched Toy Story 3 with the fam... me rollering away, them all in camp chairs eating snacks in my pain cave
5) yes, I have some Garmin workouts built with intervals and do those on the rollers... really the only time I do intervals
When I first started riding rollers I really questioned myself... it was like riding on a sheet of glass. You pick it up though and take your time with tricks. No one's handing out awards because you can one legged pedal and pick up water bottles from the floor while rollering.
