The Voltitude bike

I first saw this electric bike here.

What I love about this design is the way it folds up into this very small footprint. Have a look at the video:


It’s about 20kg (44pounds) and the max speed is 25kph (16mph).

There website is here: and they have this neat video in french:
They say, they spend a lot of personal money on the project.  They have 800 pre-order and the Chinese are interested!

In the video they talk about the price and it should be between 4000 to 5000 Swiss Franc (CHF) so that is $4782 to $5980 US.

I am 100% you saw this in the news a couples of weeks ago.


I was blown away by the design until I read a comment that linked to this:



This is NC one V2

In my personal opinion, I think that the bolt holding the motor should be replace by something else. There is 4 of them, it’s heavy! When I worked in Hong Kong, on RC toys helicopters they use to remove every single grams of weight they could! 1 grams can change everything on very small craft like this one. I would of tried a press fit plastic adapter. The plastic adapter clips in the PCB and the motors is the press fit.
