I am planning to build a 4-seater electric vehicle with the following specifications:

1. 4-seater capacity (total weight of passengers + cargo: 300 kg)

2. Speed: 15–25 km/h

3. Ability to climb inclines of up to 25 degrees

4. Steel frame chassis

I would like to know:

1. What level of motor performance is required?

2. Could you recommend a specific motor?

3. What voltage would be appropriate?

4. What battery capacity is needed?

5. What tire size should I use?
