Hi there! I have a mountain bike that I've put thinner tires onto so I can commute to work. I live in Vancouver and can technically ride all year because we only get a handful of snow days, but I hate cycling in the rain. Also, I don't work in the summers so I don't bike every day.

So, I'm looking at getting a stationary bike to use inside on days when I don't want to be outside on my bike, and also for general fitness. I looked at regular stationary bikes first but I live in a condo and prefer something that takes up less room.

Then I heard about trainers where I can hook my bike up to them and they can be folded up when not in use. I also found rollers, which I'd never heard of before but they look interesting as it's not a stationary ride and therefor (maybe) more of a true ride.

I'm in decent shape but certainly nowhere near elite. I want something that's good for cardio and some core fitness. Would rollers be the best choice? Are they really hard to get used to?

Any tips/suggestions would be appreciated! Thank you!
