I tried to search that motor and came up with nothing, however, unless its around 500kv its not going to work well at all on 3s and will probably overheat since its being lugged down to way below its best rpm.
In brief: Motors run at their best at around 75% of no load rpm. Since that motor is probally limited to around a 100 watts, and 100 watts will push a good bike at perhaps 15 mph. This means you want the motor, at full throttle with the wheel off the ground turn the wheel at around 20mph. ( use a bike speedo on the back wheel to confirm this)
I'm guessing from the photo that the motor is around 1" diameter and is likely to be at least 1000kv if not more. That would put the wheels no load rpm at around 35mph and its most efficient rpm at 26 mph. Obviously thats not going to happen on only 100 watts, so in motion at only 15 mph or so the motors running at maybe 42% of no load rpm, making very little usable power along with winding-burning levels of heat. Most of the wattage isn't making the bike go, its just getting the motor hot.
In this case, going to a 2 cell lipo would actually make more usable power, reducing no load rpm to around 23 mph and best loaded rpm to around 17 mph, a speed that might be possible with pedaling.
I am actually considering trying a very similar project just to see how it would work, but would be using a 3000kv motor in a 6.3:1 gearbox into a 1" roller on 3s. With my motor this should give me around 50 net output watts and an effective kv of around 500. I am hoping this will allow a no pedal speed of around 10mph.
