i am thinking of getting a xispa 25 for my son he is just over 4 yaers old. has any one had one if so what are they like as a starter bike, any problem with them

I have one for my 4 year old son and they are great little bikes! Just make sure you get all the exhaust restrictors out. The only bad I've had so far is the fuel tank opening is tiny and the bike is kind of loud--actually sounds pretty cool, just loud for a 50.

Got a Xispa 25, oset and razor for my little one's.

Buy an Oset for that age.
