Mid-drive has been around a while. It was supposed to be something that changed the ebike. The advantages are obvious, things like unsprung weight and efficiency. But the advantages have not proven to be large enough to push everyone to the mid-drive. Can you really say it 'won'? Can you say it has not met expectations. Was it was overdone?
If you want to make a basic bike, you probably go with a rear hub. I built a front hub (not much to it) and I like the front hub, but it will slide around if you give it too much throttle. Either way, a hub motor is something you see from China around $100 or so, more for better motors. With battery cell prices dropping, packs are getting pretty cheap. The packs offered as 'second' packs on CF campaigns have been very cheap. You should be able to build a bike way below what bikes cost in ebike retail shops, just looking at decent parts, a reasonable battery pack with good, name, cells. The value mid-drive, the BBS02, is hard to sort out. It hasn't really made an impact on retail bikes, which would be built by small shops or imported. There are high end hubs.
So it seems to end up being "If you are aiming upscale, you go MD, otherwise hub". People often don't shift hubs that much. That could be seen as an advantage. They are coupling mid-drive with auto shift, fancy internal hubs, and that is driving the price very high. Do most folks need that?
