New VAE Pipop STEE...without battery with super capacitor

[Christophe]

So that's peanuts...I think there's a maximum of 40 or 50 Wh stored...

We see one of the condos used on the video, by estimating the volume and/or the service voltage we must be able to estimate its Wh and the total Wh...more precisely...

[Ahmed]

It is not much, but it is not comparable to the type of operation of the VAE which is on pure storage, whereas here, the concept is dynamic smoothing which can be satisfied with much less reserve since it recovers fairly quickly.

[Christophe]

Do you have an electric bike? The 250W are already limited at times...

The argument of smoothing is a bit of pipo amha... if it's to pedal much harder before to pedal a little less hard after (given the losses)... I have trouble grasping the 'interest...

Without energy, no power, no assistance....

Have there been any trials by journalists in the industry?

On a long climb, it should not take very far ....

You might need a combination of the two.

Perhaps less...
We see that the map has 20 condos marked Ls Mtron. I dug up their catalog https://www.lsmaterials.co.kr/upload/22 ... n_high.pdf

At a glance, 35 mm is the correct diameter and the L/H ratio is 0.52.
If we count 71 mm high, because of the parallax error: we obtain at best 0.65 * 20 = 13 Wh maximum...

So 1 to 2 km of autonomy and counting the loss of performance, it's better to put the same price in an ultra light bike, isn't it?

All I know is: the slower I pedal, the faster I go...

I haven't been to Brussels

The principle seems interesting, but what is it really? Only a test could tell.

I am also quite skeptical about this concept of bike. If I understood correctly, it does not change the muscular energy necessary to carry out a given route, it smooths it out as Ahmed points out, for example in the ratings.
But it seems to me that the user of a VAE (which I am not), his goal is precisely to reduce the muscular energy necessary to carry out a given route, simply not to shit, or going to work without getting sweaty, or starting to get a little old and tired but he likes cycling.....etc,...
Alright, we'll see what's next.

The thing that still seems technically interesting to me is the decoupling between the "energy production" function (the pedals and the generator) and the "propulsion" function via the capacitors. For electrical engineering specialists, is it possible and effective due to the use of capacitors, or could it also be applied to a classic "battery" diagram?

[Ahmed]

I do not find it indicated that there is decoupling... Pedaling drives the bike and eventually charges the capacitors and when it becomes more difficult, the condos are discharged into the electric motor in support of the cyclist's effort.

Edit: there would be two bikes, including an electric-only model, but this is not the case with the one presented.

I only read.... If it's wrong it's not my fault!
Second link of the first post of this thread:

"With this bike, there is no more mechanical traction, so no chain or universal joint, explains Adrien Lelièvre, CEO of STEE. By pedaling, the user generates electricity, and this energy is either stored in the supercapacitors connected to a generator, or used to move forward, especially uphill... There is no longer any need for recharging.Unlike conventional electrically assisted bicycles, we are in a management of the energy supplied by the user and not in an addition of energies."
