The initial calculations

I did some initial calculations what is needed to buy for the electric conversion. The maximum weight that the Kettler go-kart can carry on is 36kg, so my son Angel and my daughter Niya can eventually drive it till they are 8-9 years old. After some calculations i concluded that 24V DC /250W motor should be good enough to drive the cart with a maximum speed of 14km/h. (a good simple speed calculator could be found here

Here is the final list of components that i need:

- 24V/250W DC motor

- 24V/250W DC controller

- Pedal throttle

- Chain

- Sprocket 

- On/Off switch

- 2x12V/7Ah batteries

- Some cables

- Aluminium part for the floor of the go-kart
