"gravity bike" turned to ebike?

they seem perfect. possibly comfortable. hugely more efficient going fast with im guessing half the frontal area.



a skate truck on the back of the whale with a 20" wheel in its mouth would be great.

Gravity bike events are short in duration. That's why the bikes can be very uncomfortable.

That seating position looks uncomfortable, Knee's to chest.

The whale looks comfy. As well as the second pic.

Here is a Lightening F-40 averaging 28 mph over a 5.1 mile segment, human powered. He peaked at 36mph on very slight downhills.

No fairings n pretty aero. Haven’t seen an e version yet. Cheaper than an ebike!
@sleepy_tired that shows how much wind is a factor: guy riding pro speeds and he’s probably not even in shape.
