I bought this bike one week before the TKR (Total Knee Replacement) on my left knee, 3.5 half months later I get to ride it and I love it!!!
Somethings I discovered:
1. My leg buckled when I tried to mount the bike for the first time, I had to get on it from the curb. Wouldn't have been so bad, but there was a half dozen riders in full kit watching from the trail. Thankfully, after my leg limbered up, I was able to mount my bike normally later in the ride.
2. The crank on my Giant has a longer reach than my stationary bike, while I have been using the stationary bike with no problem, on the first couple of revolutions on my bike, I thought the top of my head was going to pop off followed by my knee cap. Fortunately my leg loosened up fairly quickly.
3. I am totally out of shape. My legs don't feel that bad, but man I can tell that my upper body is going to be sore tomorrow.
4. I still love biking...No real surprise, but the feeling of being on my bike again, gliding down that path and feeling the burn of exercise was as good as a drug.
