Thank you Crazyfrog.
Doing the strengthening exercises, rather than the stretching exercises, as the latter exacerbate the problem. The elasticity seems to have gone PHUT!
As for the "New Thumper"! Re-cycle the ones we have and spend the money on creating a long range hydrogen and or battery powered lightweight.
Specs: All up weight 100kg - 120kg. Good for 80mph - 100mph top speed. Acceleration 0mph to 40mph in 3secs. Seat height 710mm - 760mm. Carry two people.
Or should I just buy an electric pushbike?
Good health, Bill
