Our mini moto quad was bought with all the plastic fairing badly damaged but was rebuilt using a mini moto scrambler which we got from a neighbour with severe engine damage. Between the two bikes we ended up with one that looks like this except it is yellow with blue flames.
My son loves this bike. maybe it was helping build it, maybe the noise it makes ( very annoying actually, but he likes it), or maybe just the feel of it, but this is definitely his favourite. It is definitely a much faster bike than the quadzilla I reviewed earlier, but like the quadzilla, it has an adjuster so the parent can set the maximum speed. The minimum speed for this is meant to be 5 mph. At the lowest setting it does go faster than the quadzilla at it's lowest.
This bike has a string you pull to start it - and pull and pull and pull. I find it very difficult, but my husband has no problem, nor do the teenage boys in the neighbourhood. I do not like this bike nearly so much as the Quadzilla. it makes more noise, more exhaust, uses more petrol despite being lighter and does seem that it would be easier to roll.
On the plus side though, because you can swap parts over with mini moto scramblers, it is much easier to find parts for. It also runs well enough and can carry an adult as well, or even an adult and a child, but not as comfortable as the Quadzilla.
My son says he loves it because it is fast. he likes the way it looks too and the throttle is much easier on his hands. The throttle on this also allows him to keep the bike going while dancing on the seat. He also likes that this bike will make sharper turns.
The teenagers all prefer this bike, and I would say it would be a better choice for an older child. Style, speed, and handling are its three main selling points. Add to that easy to find parts for and work on, and cheaper to begin with and it is a good wee bike. My son is 5 and has been riding this for one year now.
