So I haven't cycled for a good few years, am rather unfit but really want to start to get back into cycling. My old bike has long gone. I live about 5miles from work and have just acquired a tidy, roadworthy Raleigh Twenty. How easy would it be to start riding this on my commute after a good few years away from cycling. Don't want to buy a decent bike as if I don't end up liking it(riding to work) I dont want to have an expensive bike going to waste.
