Regarding the motors, they wouldn't be suitable for this particular project but you can buy broken hoverboards really cheaply. Where I live you can get stripped ones (no battery, no logic board, but you can get hoverboard logic boards on AliExpress for under 20€) for 10€ and returned ones (99% of the time it's a dead battery) for 35€. The motors are fantastic and powerful (~350W each), and you can build lots of stuff with them. There's a great talk on how to use these things to build all kinds of moving objects (armchairs, bobbycars, motorised cargo carriers: https://twitter.com/JanHenrikH/status/1023218344282021888 https://twitter.com/JanHenrikH/status/1023218344282021888, ...) at https://www.youtube.com/watch?v=qnQSL9DBPaE https://www.youtube.com/watch?v=qnQSL9DBPaE. You can motorise anything this way for around 100€. The only thing that's hard to come by cheaply is the battery.

> The only thing that's hard to come by cheaply is the battery. Dead laptop and power tool battery packs usually have at least some useable 18650 cells in them. A friend has built more than one battery pack for electric scooter out of harvested cells. You do have to know what you're doing when working with unprotected cells though.

  Yes it's easy enough to get unprotected cells, but the hoverboard batteries usually have short circuit and undervoltage protection, both of which are very nice to have as a beginner. If you know what you are doing you can also get RC hobby batteries for not too much money.
