what that means? i am looking for a mini dirt bike on ebay and it says 50cc does any body know what that means because its a bit confusing and does any1 kno how big they roughly are
Hi,
50cc means 50 cubic centimetres or 50 ml (millilitres). It is the capacity of the engine. I would say it's big enough for a mini bike although there are larger engined models.
Have a look at http://www.pocketbikez.co.uk/products/mini_bikes/mini_dirt_bike_yellow.aspx for a quick rough idea. It's a site that sells them but it gives enough detail for you to see sizes and how fast they go.

50cc is the maximum size for a moped. A 50cc engine can just about enable a lightly built bike with one person on board to maintain 30mph on a smooth level road. I used to have one and it crawled up steep hills at walking pace.
A 50cc engine is not powerful enough to propel an adult over rough ground.
