Dr.'s advice

After pronouncing my leg to be "beautiful", my doctor gave me the ok to swim and ride a bike. BUT I can only ride a bike on the condition that I add two extra wheels onto the back (aka training wheels) because if I fall I risk serious re-injury. The bone isn't 100% healed yet. He said if I don't want to add training wheels I have to wait 2 more months to ride.
What do do? Having no transportation REALLY sucks!
