Welcome. I've been riding since 07. I was lucky in that my neighbor, who got me riding, had 4 different types of bikes. The hybrid, which has some road aspects with straight bars, was the one I gravitated to. I was able to ride that bike for weeks before I decided a hybrid was right bike for me to buy. Four years later, I've upgraded to a road bike. Not sure you have the opportunity to ride some different types to see what works for you, but that would certainly be an option worth trying to find.

One other thing, with regards to buying an inexpensive bike, if it's what you can afford, then by all means get the best bang for your buck. However, if it's just because you don't want to spend much on a first bike, well that may or may not be the best decision. A good bike should have a decent value years down the road. A name like Specialized, Giant, Trek, Cannondale, etc, command better pricing when looking to resell or trade up. Just my thoughts there.

Good luck to you!
