Super, sure, superhuman, no… someone running in shoes isn’t superhuman compared to someone in bare feet, anymore than someone using a block and tackle to lift or a wheelbarrow to transport is engaging in superhuman acts just because they’ve used their very human brain to leverage a simple machine.
Something like this expands the envelope of what is, definitionally, the realm of natural human capacity… it pushes what qualifies as superhuman further away, but it doesn’t mean you’ve done something superhuman.
Sure… and, notwithstanding the apples to oranges comparison — since I can outswim or out stair climb you when you’re on a bike any day of the week — that means you’re demonstrating how fast a human can turn a crank that a human has connected to a wheel that a human has realized will transfer traction into forward momentum; nothing remotely superhuman has occurred, your maximum speed with that implement is still entirely limited by your very normal human capabilities.
Actually you probably can’t, assuming you aren’t a world champion cyclist and you’re starting from a standstill. 100m is too short to capture the advantage unless you’re very, very fast.
