I do not know much about motors so I was wondering if you all could help me out a bit here. I am looking for a small electric motor that does not need to accelerate fast, but can propel about 150lbs as fast as possible when connected to a 110mm wheel. It will need to be battery operated. I am a bit flexible on the dimensions, but would prefer it to be no larger than 100mm x 100mm x 100mm. I hope I explained it well enough for you all to understand. If not, let me know. Price at this point isn't an issue. Thanks a bunch!
