'2old's' YouTube video makes the point of lack of standardization:


I plan on building an inexpensive e-bike. But as the video points out, those who plan to purchase a manufactured e-bike have a lot to consider also.

'late' said, "One of the rules of life, don't buy crap." But how do you know for sure you're not buying crap?

I'm gleaning knowledge and wisdom from everyone,.I want to make a safe and affordable e-bike.
