+1 for finding out the bottom line cost, as objectively as possible.

Here's an article that mentions 20,000 + run hours out of one manufacturer's brushless motors:

"Hargraves Brushless DC Motors (BLDC) are designed to endure long life applications that under certain conditions exceed 20,000 hours of operation..."

So I'd edit the engine/motor lifetimes to favor electric more.


The battery replacement cost will probably have to have several branches, depending on type and capacity, but I think $500 every 10k sounds realistic.

Also, initial ebike setup is more like $1300-$1500.
