Is it stupid to buy a bicycle when I already own a car and I am an excellent driver...

Depends on how far you plan on riding daily and what the weather you gotta deal with is. If you're riding to work, are you going to arrive smelling like you just got out of the gym or the shower?

>It's even eco friendly
bikers put too much oil on their bike and are the #1 reason for oil leakages

Bikes are great. Biking is great. Wear a helmet or you're a dumbass and will deserve it when you get your egg cracked.

BUY USED. Craigslist, pinkbike, etc. Bikes depreciate a lot for basically no reason. The parts that wear are cheap to replace. For the same price you could get a crappy regular bike, or a used high performance bike from 5-10 years ago that will be much better in the long run.

they are a lot of fun though

>look like a kid pulling up to the bar on a bike
Nah, you'll look like a fitness buff if anything. Chicks dig bikes. And you won't go to jail for riding it home drunk (in most places).
>whats wrong with OP image bike
nothing really, it's just a cheaply made mid-low tier model and you could get a much better used bike from a better company for the same price.

Get a road bike. Why would you use a mountain bike to ride on the road?

to have the choice to go off road/through the woods

Funny thing is I am a fitness buff, I am 6'1 and 200 lbs with a developed body. But I am trying to get away from that label because people think you are obsessed with the gym. The bike in the image is the one I was going to buy because it's on sale, brand new for 400 dollars.
I want the versatility and the roads here are a disaster
