When our shop first started pro fitting services we had a big demand from riders to get their positions more upright on older bikes. This was before endurance geometry, gravel bikes and the like existed. What we quickly learned was that although a "fit" could be obtained, it was far, far less than ideal and ultimately led to a new bike with correct tube lengths for the rider. I strongly suggest returning the bike to the vendor and focus on an endurance road bike or a road hybrid bike from a bike shop where they can properly size you, or better yet, professionally fit you to a machine. A sows ear can be dressed up to feel like a silk purse, but in short order it will reveal its true identity.
