I got a ladies Schwinn Breeze, it 's probably about 40 or 50 years old and all the bolts (though they looked "frozen" ) all came loose with no problem, nice components it has a Sturmey Archer 3 spd shifter with a little oil filler cap on the rear hub.... just a good old bike, incredibly even the tubes are still good but the tires are dry rotted.. I'm gonna make it rideable. My question is; is this a good candidate for an engine?... it'll fit... but is this a strong enough frame in the "ladies configuration" to handle the stress of motorization? has anyone done one of these or know of one that was motorized?...... thanks
