Keep it up!!I know this is an old thread but if gets one person back on a bike then it's worth the effort. I am 71 years of age this year. I retired from the fire service at the age of 46 with moderately severe spinal injuries. I kept reasonably busy as a facilities manager with a large government dept but my injuries took a turn for the worse resulting in two further major operations. Still I kept as active as I could but gradually did less and less until I had a heart attack over two years ago. My spinal degradation also progressed quite rapidly until I was only able to walk very short distances and only then with a walking frame. After the heart attack I was determined to make an effort to get on the move and my doctor suggested a bike. I laughed of course barely being able to walk but a short time later there was a cycling event in Warrington and the lass on the advice stall suggested an ebike. I thought about it but my first option was to buy a cheap ordinary bike and see how I went on. Well, surprisingly, my back pain actually receded when sat on the bike and I was actually able to pedal fairly comfortably. Balance was a problem due to difficulty starting from rest and my wobbles were positively lethal until I got some speed up. I struggled but improved daily. My only concern was overdoing it and not being physically able to get home. This is where the ebike came in. It gave me the confidence to cover greater distances knowing I had the facility in the Bosch motor to get home with greatly reduced effort. Launching from rest is improved but still not brilliant. I just wait till all the traffic had moved off before moving or use cycle lanes as much as possible. My fitness has improved greatly and I look forward to going out every day if I can. I use the motor as little as possible but it is there when I do have need of it. It has changed my life more than you can possibly imagine so if you are giving it some thought just go for it. It's the best thing I could possibly have done.
