I just got the crazy idea of building one of these motor-bicycles 2 days ago. I am actually planning on getting my motor first and just buy a bike that will fit the kit best at my nearest store. Not sure what I can say about myself....PC tech that loves building things and trying new things and this will just add to the adventure that is life. Its been pretty much nonstop research since the day I stumbled upon motobicycles and the question i keep asking myself is what engine kit to get for my first build!? and finally it has come down to one of these two Since i cant post links... the two are both from kingsmotorbikes and i havent decided if I want the: GRUBEE StarFire GT-2 48cc or Jet 80cc Both 2 stroke engines. I will probably order one of the two as soon as I wake up tomorrow and was hoping someone would give me some input. Thx in advance.
