Get a couple of em , some people put them in karts and they weigh about 120kg and go very fast.

Quote from ColeusRattus :

Allright, that could work. Still, it would need to propel a much larger weight than in the video. Let's say 15 for the bike and 75 for the man opposed to 150 + 75 if you have only one passenger

so? the thing has a max output of 7kw

the dude's face at 6:10 is priceless
