Honestly, if you're new to biking, I would go to a local bike shop (LBS). Not because the bike you posted is bike, but because of
FIT. A poorly fitting bike will be a downright miserable experience and you'll quit on biking as it removes the fun
I've been cycling a lot of year and I moved to Germany and had a bike fit a by a standard sales person and just a subtle change in stem length made all of the difference.
Now, I live in the UK, but stateside, this is probably a $300 bike at a local bike shop and it's quite solid and they'll perfectly fit it for you
