Next year, around this time, I plan on a doing a 2-month, cross country ride from San Diego to Virginia Beach. Currently, the bike I have is an entry level 1983 Motobecane Mirage Sport that I have been training on for the past 2 years. However, I do not think it would be a good option to take across the country. I am looking to spend about $1000-$1500 on a bike within the next year, so what would be maybe the best overall option for this type of ride on this type of budget? Or do I need to maybe think about spending a little more?
