Drivetrain and donor-chassis options

Selected design questions from the working sessions. Alternatives are not labelled as the final build.

Keep the car, or change the starting point?

The discussion compared upgrading an existing electric ride-on, buying a used chassis and adapting a pedal kart. A BERG conversion was one possibility; a larger electric buggy was another reference point.

Area Question explored
Motors and gearing How would the available motors, reduction ratio and wheel size affect the result?
Chassis Would an existing ride-on or a pedal-kart base make the conversion easier?
Mounting Could available components be used without fabricating every support?
Wheels and suspension What changes would suit a road-oriented car rather than an off-road buggy?
Cost How would buying components compare with starting from another vehicle?

What the comparisons did not settle

The conversations used several voltage and vehicle configurations. They do not identify the final electrical setup or prove which donor chassis was chosen. A reduction ratio was also missing from the speed discussion.

The useful artefact is the set of design alternatives and constraints. The assistant's speed estimates, compatibility assurances and shopping lists are not presented as tested build instructions.
