Cyclists are still largely using chains and a mechanism to bodily rip
the chain from one cog to another to change gear as the efficiency of
the simple belt/chain transmission/
The chain systems are in the high 90s% efficient. The hub gear systems
tend to be some what lower - mid 80s to mid 90s% efficient.
Like our e-boats, cyclists want maximum power transfer with the minimum
of transmission losses.
