There’s a belief that four wheels must be safer than two wheels. This translates to a belief that all-terrain vehicles (or 4-wheeler ATVs and quad bikes) must be safer than dirt bikes. But it appears the opposite is true. Research and statistics show that victims involved in ATV crashes are more likely to die or suffer serious trauma than those in similar accidents involving dirt bikes. Therefore ATV riding crashes are more deadly and more injurious than dirt bike crashes.
My conclusion is that the pros of dirt bikes outweigh the cons vs the cons of 4-wheeler ATVs outweigh the pros. These ATV vs dirt bike pros and cons include comparisons over their safety; the cost of each vehicle; how easy they are to store and transport; the cost of running each vehicle; how easy they are to ride or learn to ride; plus more.
Dirt bike seat height chart from adult size dirt bikes for heights of 182cm+ (6’+) down to kids size dirt bikes aged 3 to 4 years old. The seat height chart includes the height of the seat in centimetres and inches. Also included is a rough guide of engine size and cc for each seat height.
Motocross or scramble tracks on private property for your own use can start at roughly 1/2 acre. But you are best to acquire an area of land of an acre+ to create a reasonable sized personal motocross track. One acre of land will allow you to have features that include undulating land with dips, mounds and jumps. Planning permission may be required for the creation of the man-made jumps. Think about noise levels and the location of your motocross or scramble course.
How old should you be to ride a dirt bike does depend on the child. You may be surprised to learn that kids as young as 3 years old can ride small electric dirt bikes. Kids at the age of 4 are progressing to ride small petrol (Gas) dirt bikes safely. Perhaps with training wheels. Then kids aged 5-6 upwards are riding petrol (gas) 50cc dirt bikes without training wheels and even learning to take small jumps.
You may be surprised to learn that children as young as 3 years old can ride small dirt bikes, but I suggest at this age it’s on an electric dirt bike rather than a 50cc petrol dirt bike. But also children from the age of 4 can safely ride 50cc dirt bikes, but they may need training wheels to begin with. If your kids start from a young age on an electric dirt bike, there’s no reason why they won’t be riding a 50cc dirt bike quite easily aged 5 or 6 without training wheels.
