BERG Extra AF Blue Pedal Go Kart
The Extra AF cart from Berg has many of the best features available for pedal go carts. The ZF gearbox gives you a forward and reverse gear, and freewheeling (which means when you are going along, you can stop pedalling, as on a bicycle). The appropriate forward or reverse gear is selected automatically depending on whether you start to pedal forwards or backwards from rest.
Swing Axel
Otherwise known as a floating front axel, this feature gives the Berg Extra more stability on uneven terrain because it allows the front axel to adjust itself to a slope or uneveness. This also increases the smoothness of the ride on bumby or stony ground.
