Dirt bike style and racing style mini motor bikes (47/49 cc). Two complete bikes and extra parts bikes. Will need a bit of tweaking to get two to run and a bit rough looking. Also comes with two helmets (xs and m). Great project. My kids loved them but have outgrown them so were just sitting for 1 1/2 years. China bikes, so very finicky and takes constant working on, but easy to work on and parts are relatively cheap if you wait for the slow boat from China.
