1000 watt inverter to power treadmill motor and controller?

I was planning to use a treadmill motor and controller that I found in the trash on a bicycle trailer to power it,geared down for slow speed with sprockets,since the motor is rated at 130 volts dc there was no way I was going to put that many batteries in there.so for fun I hooked it up to a 1000 w inverter and a single 12 v battery and it runs great. does anybody see any unforeseen disasters,not including a long visit to the hospital. has anybody tried this yet and not failed miserably ? ? I'm also curious on run time under load and with about 200 amp hrs @ 12v. any other nut jobs out there ? 

Its perfectly feasible to do it, but the run time depends on the batteries you throw at it, and how wide open you run the throttle.
