Check this out for a BEAST:

you could check out my beast! Goes 30 km’s 20 miles without problem… And with a wireless connection ! 
The gnarbboard weighs 86 pounds! So think it qualifies as a beast! They went just-about out of business… nothing is for sale any longer. I appreciate the innovation, but clearly newer (and better) technology is available now.
Just wanted to weigh mine. 33 pounds with battery. and mine has pretty comparable stats.
mine gets better range, has the same stat battery except mine is LION, mine is faster, not sure about acceleration
