Not sure when @AlephNull built their bike, but prices seem to have fallen on retail ebikes in the last few years, the difference between DIY and retails seems marginal now where I am.
Bosch motor or shimano steps seem to do pretty well, they're common on most major bike brands.
The difference is still absolutely huge, really. But you do have to be more tactical where you buy the components and which ones you buy.
You'd also have to buy a used bike for it to be the absolute most frugal. If you can make the battery yourself also then you get absolutely massive savings.
