Here is an updated pic of the bike. I put a 22 pin chainring on it bringing the ratio to 18:22 (1:1.22). This combination allows for 9 possible skid areas on the tire if stopped with only one foot.
In order to get proper tension on the chain I had to file down the back of the dropout about 1/4". The chain is now tight and very responsive. There is no play when switching peddling direction.
The peddles are also an addition. Flat peddles seem best for the artistic cycling type tricks. Those peddles actually fold in to save room and as a result wiggle a little, but I cleaned them and applied Gorilla glue to make them firm.
The bike is horrible for getting A to B, as the gears are so low that even a moderate speed would require superhuman effort to achieve. It is, however, a godsend for tricks, especially those involving going up slops, peddling backwards, and balancing on the spot. Skids are much, much easier to do.
