Easy as Pi

Canon PowerShot G9

ƒ/4

7.4 mm

1/320

Two models: all electric and humano-hybrid.

The Li-ion batteries are inside the recycled aluminum monocoque arch.

10 cents to charge, 30 mile range at 20 MPH.

Here’s a short video of my first ride on the Pi (the all electric one in back with pancake motors in each wheel hub).

They said you can go as fast as 64 mph on the electric one!

looks like an awfully long arch.
i guess that’s what the swivel seat is there for 🙂

Yeah….The seat swivel is pretty sweet and helps with "one size fits all"…. and makes me wonder if other bikes could benefit from it.

avlxyz: the diameter and smoothness of the arch makes me feel more comfortable. Contrast that with the Delta 7….

Slip off the seat on this puppy, and it would be like landing on a cheese grater…

As an investor in the company that designed this bike, I’m pleased to see it featured here. Marcus Hays is the designer and deserves full credit for making the most iconic bike design since the BMX.

The Delta 7 looks like there was some inspiration from nano-tubes.

i like the bottom bracket mounted motor. this is a good way to improve efficiency by using the existing gear set.

similar to Stokemonkey for those who would retrofit…

Autodesk has a display of how they fit everything inside the arc:

"10 cents to charge, 30 mile range at 20 MPH." Sounds to good to be true.
