u/Here-As-Is

Hi folks I’m new to cycling (haven’t picked up since school) and right now since I’ve started out on doing cardio (almost for 2 months now )- I’m planning to pick up a hobby of cycling as I feel it’s more fun than running (sorry runners!) . Now I have a deal of getting a “Firefox Road Runner Pro D- 21 inch” for 15k. This includes set cover , lights and mirrors. Do you think this is a good deal and is this a cycle that’s a good fit for me ?
