I took my bike for a ride today, first time in a month with this device on & could not realy tell the difference, the Dyno will tell me if it works. The wife nearly killed me when she found I had gone around the block with my stuffed leg. I said I was ok I took off my leg brace & could ride fine as long as I did not stop & put my leg down.
