While waiting on the DHX motor, I decided to pursue building a kidkart.
The goal is to build a kid kart that is initially "inexpensive", has the battery capacity to last all day on one charge, and a programmable controller to limit the motor to top-end Honda GHX50-ish power (what they run locally). It will be air cooled and IP65+ rated so it can run in the rain.
I’m currently looking for a “local” roller to start. I plan to employ my grandkids for the R&D testing, with my younger granddaughter being the top candidate (although slightly too young yet). I have a good handle on the motor, controller, BMS, and battery size.
Once the bugs are worked out, I will build at least two more so they can race as a class.
Motor and controller wise I think the pair used in the below video would be adequate for a kid kart and possibly cadet. This is an ME1717 with Kelly controller. Pair that with a BMS to make running and charging safe and a 2kWh battery and it should move.
I do have a cadet chassis, but would rather put this on a kid kart - still looking if someone has one (no motor required).
