Vhelio, ein Open-Source-Projekt - Solartadpole für zwei Personen

As it is a French project so I sacrificed myself and read some more. Based on the xyz system? :unsure:

- 85 kg, powered by the Bafang M400 so torque and PAS.
- System weight 200 kg. 3 x 210 mm disk brakes.
- no suspension, they rely on the balloon tyres and the seat suspension (inner tubes)

Frankly after seeing Green Mamba "in the flesh" I think a quad is a much better idea when the weight goes over 50 kg. I downloaded the plan, it is very complete, instructions in OpenOffice format and the drawings can be opened in FreeCad.

There is a full electrical schema which might be of interest to some people, including the custom circuit board. It is under the CERN Open hardware license S.

Everything is in French of course... The 3D PDF plan requires an Adobe tool, it does not open in Linux for example.

However, it is much easier to build if you have one wheel in the back. It also frees the sides for additional storage. The little wheels on the side prevent scraping the ground and tipping over. One could also build two bigger side wheels that always touch the ground, with fluffier tyres to add some bounce.
 
I looked at the commercial version, it will be more expensive than a pony4 I think.

A long/heavy load pony4 with a structure for a solar panel weighs half (with soñar PV system) and carries the same load :unsure: OK pony4 does not have a seat for an adult passenger but it will carry 2 children.

The Vhélio seems to be able to seat two adults and two children though...
Commercial version may be expensive and heavy. But I am thinking about building this thing with lighter wood, to suit as a one person camper.
The three-wheel construction with low base seems to be ideal to make room for storage in the sides, while providing a level plane for the sleeping area.
Any four-wheeler will have complicated additional transmissions and two wheelhouses that take up space. And weight for the additional wheel and suspension.
 
EDIT: I read the instructions... It is 85 kg plus 200 kg load = 285 kg system weight

My camping mattress is 65 cm wide, that leaves 10 cm on each side for the rear wheels. Suspension is overrated ;) I would just use 2 x freewheels like the pony4 for the drive or maybe drive just one rear wheel down the side like the 441?

I think you could save quite a bit of the weight as a camper with a platform on top of the central beam.

In the Videos, several adult people are seen mounting the vehicle. Maybe not uphill, but that's where the people come in handy :)

65 cm mattress is a bit small. I would like it as wide as possible - of course the central beam is the level of the platform. The side parts are for storage, battery etc., which is
also good for low point of gravity. I see no problem there, just advantages. And you can even make the storage accessible from outside, if you want.
 
I did an edit, 285 kg system weight works.

I thought that the mattress was narrow when I bought it but I slept very comfortably on the road. A standard "mummy" shape mattress is 53 cm wide :eek:

The Green Manba trailer is similar, the sides fold up making a nice awning, euro boxes slide under the platform. The platform is above the 20" wheel here as well.
 
Das basiert doch auf dem XYZ-Trike, oder?

Wenn sich in den letzten Jahren nichts grundlegendes an der Lenkgeometrie des XYZ-Trikes geändert hat, fährt sich das Ding einfach nur richtig, richtig, schlecht. Bei meiner Probefahrt vor ein paar Jahren hab ich mich wegen des miesen Händlings mit dem XYZ-Trike nicht auf die Strasse getraut.

Ich glaube nicht, dass es direkt auf XYZ basiert, die sehen ja anders aus. Die einzige Gemeinsamkeit dürfte die Bauweise aus den Aluprofilen sein. Es gibt ja auch nicht wirklich viele Variationen eines Trikes...
Wie sich das Ding fährt, ist doch auch von der Einstellung der Lenkgeometrie etc. abhängig?
 
Von der Homepage:
"Der Verein und die Vhelio-Hersteller arbeiten ... daran, die ersten Vhelios ..... verfügbar zu machen." Ein Online-Bestellsystem soll kommen.
Da die Pläne für Selbstbauer kostenlos erhältlich sind, nehme ich es als Bauplan in die Liste. Ich habe mich in die Liste der Interessenten eingetragen.

Ich nehme es in die Überblickstabelle

Lieferbare Velocars für mehrere Personen auf.
