Assuming a one second interval, it's hard to get more than about a 1% variation from the "straight lines between periodic samples" vs a real bike tire path, say a 10mph u-turn in a 60 foot wide street.
This illustrates it better. I'm assuming your "samples" are every 1 second.
I pointed the same thing a couple of days ago.
GPS Distance errors
Real measurements would not be quite as neat. The real locations hop around quite a bit.

I don't think this would help much. The variation is going to be constant. You'd just get more noisy points with increasing the sample rate at a lower speed.
It would be better to have smaller location variation.
