The reed switch could just trigger something like a simple retriggerable single shot 555 circuit to provide power while moving and kill the effect when you stop.
Nice. The 10-cent 555 with its ~100 mA output current capability should be able to drive the module directly. I'd also think that with clever application of the single-shot timing, you could power the module less frequently at slow speed when starting to move or slowing to stop...then power it 100% above some speed threshold. I'd think this might improve the effect - more sparking at faster speeds.
