I had my stent 2 years ago after 3 heart attacks, the first 2 were on my mountain bike I just felt really rough with no energy and a strange feeling in chest (not pain) I just rode home slow and slept. The 3rd one I collapsed walking up an hill. Consultant said I was extremely lucky. Anyways, attended the cardio rehab, cardiologist said you have adjusted your lifestyle now just keep the good work up and forget about it, just adjust life to the medications, beta blockers are awful when you bike up a hill, I collapsed and fell off much to my families amusement.
But hey, guess what 12 months later I purchased my first ebike, those hills are now climbed with a grin.
Have had the carrera for 12 months now and absolutely love it to bits, combined with a samsung gear fit 2 heart monitor I reach my target heart rate and don't push it past that..
My cycle routes range 6 miles. 10. 14. 18. 22 and 35 miles.
mixture of flats and hills and loving every ride
