That's sort of what I thought right away too - "Sounds Great!"
I find it really interesting how different combinations of electronics and drivetrains all have unique sounds.
My DC-chain drive cycle sounds different than this drive-shaft EV cycle, and my Cougar-controller DC Geo Metro sounds different than Tom's AC Dodge Neon.
I like the way this cycle sounds - it almost has a little bit of a scream to it. (It is also possible it needs some lubrication somewhere!
)
