Just had my latest doctor visit and while I haven’t lost that much more weight, my blood pressure is much lower. The doctor is talking about eliminating some of the BP drugs I’m taking. Great news!!!!! Lately I have been researching a product called Kneesavers. This is a spacer that goes between the crank and the pedal. It the pedal away from the bike. On other bikes that I have, this has been a great product. Keeps my heels from rubbing on the bike. I will let you know how they work on the Optibike.
