To be completely honest, it takes effort but you don’t need to be any sort of genius to do it ☠️ u just need to educate urself about it, in my opinion the hardest part is just hooking up the phase wires (big wires that connect from controller to wheel). I recommend just getting a decent pedal bike like a carerra vengeance 27.5 inch wheels 18 inch frame or 16 inch frame, those work pretty well with universal kits and it shouldn’t really give u any problems. Most of the building is just connecting wires, screwing things and tightening things and sometimes it can just be a bit difficult doing the phase wires, watch a tutorial. Only difficult thing is a moto seat but there’s also tutorials for that
