A Mechanical Engineer's Designey Take on an E-Bike

Enzo Prathamesh Shinde's Vinci

The latest designey, unlikely-looking e-bike is the Vinci, designed by Enzo Prathamesh Shinde:

"I am not reinventing electric bikes. There are plenty of them available in the market," says Shinde, a California-based mechanical engineer. "But I didn't want to have a lame electric bike with some electronics slapped on a regular bike or an older Bonanza mini bike frame. [So] I came up with a design that satisfies my requirements of style and comfort."

Shinde claims the Vinci's 48V 15aH lithium-ion battery will be good for a 35-60 mile range, and can top out at 35mph for those in a hurry. If it sees production the plan is to retail it for $1,250, though he's currently attempting to Kickstart them for $999:

At press time the Vinci had about $11,000 in pledges towards an $111,200 goal, but there was still 58 days left to pledge.

How do you adjust seat height? Is there an option? I can understand if you just run on electric motor but pedalling is more awkward/ difficulty when seat height is wrong.

  You have a good point, on "bikes" like these the pedals are kept to keep it in the realm of bicycle and skirt regulation and laws about mopeds/motorcycles.

Also what is the point in referencing a Honda CBR 600 RR motorcycle geometry when building a pedal power bicycle? Why not just reference an actual bicycle? The final product seems to share none of the moto proportions anyway....
Is this meant to be an example of good design? Or good design intentions gone bad?

Why not put the heavy battery down low in the down-tube area instead of way up under the seat? This design puts the majority of the weight almost as high as possible on the bike which will hurt handling. People usually stick electric motors on existing bike designs because the bike design actually matters. This example is basically putting wheels on a huge battery.
-- Lack of adjustable seat is a great example of why a mechanical engineer needs to consider ergonomics.
Also, in the pic with the rider, that batter is like 2 inches from the fender...I'd like a bit more clearance if I was riding city streets.....hope that shock doesn't have much travel.
