Hi I am a 47 year old male, 6ft. 2in. 280 lbs. with a bad neck and right shoulder. Thinking about some type of steel single speed road bike for a first bike after a 30+ year gap in riding. I am thinking I will need to be in the most upright position possible because of neck and shoulder. Also fatter 700c tires to support my weight and lower gearing until I can start getting back in shape. [QUESTIONS] Am I on the right track ? and if so how do I get started ? THANKS.
