If anyone could help with this....

I am trying to convert either a 115 volt or 220 volt condenser fan motor into a DC motor that will run my bicycle... what would I need to make the conversion...

"Condenser fan" is an end use, not a motor type. Can you provide the manufacturer and part number?

If this is a shaded pole motor or a capacitor start motor, it will be prohibitively difficult to convert to DC. (Easier to build a new DC motor from scratch than to convert.) If this is a universal motor, (and many condenser fan motors are) no conversion will be necessary. "Universal" means it will run on either AC or DC. (Sourcing the 115vDC might be problematic, though.)

Agreed on all points regarding the conversion. I work with this kind of gear every day, and find it amusing, because there ain't a condenser fan motor out there with enough cajones to drive a bicycle anyway :D
