Description:

Here is my son’s electric dirt bike says 18+ mph but depending on weight I had him at side of me doing 25 the bike is in like nearly new condition on full speed least about half hour full out at the moment it at setting 3 top and can’t find key but they are not expensive to change but hopefully find before sell and it’s not had that much and not that hold but got done on field so upgraded to petrol has it’s better on tracks and now he wants to sell this for a better bike
Swap for something petrol no gears preferred no pull start let me no what you have
