No Hip but a while back i had my L knee replaced. The DR said 3 months. Yeah right. I was riding at around 3 1/2 weeks.
Before that i would go down and sit on it. Around 4 weeks they stopped my PT. I was one of the fastest people they had ever had. Riding my scooter was a big motivator. I suspect you'll be the same. When i started back riding my first ride was 15 miles. I definitely over did it. One thing to remember is how ever many miles you do, your going to have to get home so double it. I was so happy to ride again that it didn't dawn on me that i had to get home.
Good luck
