Dankeschön! Ja es gibt schon Pläne sogar für dieses Jahr, aber was für eine Idee hättest du denn für eine weitere Tour oder den Bau eines neuen Solar Betrieben Gefährts?

@@kilianweigand Eine ganze Menge, bin selber grad am bauen :) Als Idee für dich hätte ich entweder ein TÜV zugelassenes Solar Auto oder ein solar Velomobil (also quasi euer aktuelles Fahrrad mit mehr aerodynamik) :)

Sehr cool! Ein Velomobil bzw. eine Solaraerohauber ist aufheben Fall ein Projekt, was ich noch angehen werde :)

Wir haben zwei 36V 310W SunMan Solarpanels und haben diese in Reihe mit einem Victron MPPT Laderegler verbunden. Unser System läuft auf 48V

@@kilianweigand ok und die verluste von 36v*2 (in serie geschaltet?) 72v auf 48v sind ok? Wäre noch optimierbar oder kommt ihr mit der Ladung zurecht?

Mit den Victron Ladereglern ist der Wirkungsgrad mit Stepdown ziemlich gut. Für das Rennen hatten wir einen externen Stepup und die Panels parallel (da Regelwerk) aber das ist deutlich ineffizienter als Reihenschaltung

Thank you :)

Thank you for the good suggestions for improvement. We did exactly that in part 2 :) here is the link: kzfaq.info/get/bejne/Z6p0pdOo3pbHdH0.html

That wasn‘t the meaning… it was about the comfort and easyness of riding through Europe by bike and that things are more difficult outside of europe

danke für das tolle Feedback! Am 18. August erscheint die dritte Folge unsere Solarbike Racing Serie :)

Lol, it has electric batteries which charge when they use padel and they also add solar for supper and it has motor also

that`s right :) We ride on solar and muscle power but with 600W of Solarpower and a Motor I would call it a Solar powered bike...

Thanks and happy to hear that! Yes spokes and rims are a challenge for tandems especially with Hubmotor and high speed. We were running a Andra 40 36spoke Rim but you can see the challenges we had in the next episode : kzfaq.info/get/bejne/Z6p0pdOo3pbHdH0.htmlsi=rdj-BAt_AZAD8917 I don`t know the best option but we went for the Andra 40...

If you have any other ideas please let me know!

​@@kilianweigand Thank you for your reply! I have seen your second episode, which I very much enjoyed. If I am not mistaken, you have used the standard hub motor wheel with its original rim on your Azub Twin, not an Andra 40. And it looks like the bike is originally specced with Remerx rims. Going by weight = strength, Andra 40 is about a kilo and the heaviest on the market, so I'd say you cannot do any better. I did look up steel rims, but they are rubbish quality and not widely available. Your spokes were breaking. I don't know whether they were upgraded or changed but as an example Rohloff specifies ONLY Sapim Race double butted as opposed to Sapim Strong. I believe their idea is that a more compliant double butted spoke has a longer cyclic life than a thicker spoke. It may be worth going for quality butted spokes on the motorised wheel. ALSO I plan on putting a bit more weight on the front wheel by adding front panniers and placing the battery, water bottles and other heavy items forward. I'll also be running a front hub motor in a 26 inch wheel. It looks to me like a lot of tandem riders have too much weight at the rear of the bike. And finally, when building a wheel, equal spoke tension is very important for long life. Lets say you have 2mm of wobble but equal tension, this will be fine because you are running disc brakes anyway. Oh and finally, I would use at least 2 inch tyres to save the wheel system from impacts.

Happy to hear that!☺️

Or an African passport 😊

thank you! We really appreciate the positiv feedback! We used a rear wheel hub motor with the option of regen. It was direct drive BUT with already that much weight on the rear wheel we didn`t wanted to push it even more. We had a lot of broken spokes and also a broken rim because the bike with us two riders is around 240kg and we obviously were pushing it quite hard. For the next Solarbikebuild we will try to make regen possible. It`s just so good for long up and down riding

Thanks man!

Let‘s show it the world out there❤️

Thanks!❤️ so happy to hear that!☀️🚲

Thanks man! Makes me very happy to hear all that good feedback! ☺️ yes it‘s an Azub Twin🚲🚲

merci!

dankeschön!💪🏻

IS THAT A JOJO REFERENCE !!!!!!!!!!!!!! SEASON 3

Das freut mich!

Çok teşekkür ederim! Fas yolculuğumuzu burada gör : kzfaq.info/get/bejne/Z6p0pdOo3pbHdH0.html

非常好！慢慢上坡可不容易，因为很快就会倾斜

@@kilianweigand 非常敬佩你们的壮举，很有创意的改装这真的很酷，路上行人的回头率应该是我们骑行者的共鸣,倡导绿色环保出行和自行车的物种多样性去享受旅行的乐趣🦵🚲🚥🏔⛰🏞⛺🌦🌙

We are using two 310W SunMan Panels -> 620W in total

@@kilianweigand nice, thank you

We have crossed the phyrenees. I can tell you that 2000m of elevation is not flat haha

@@kilianweigand that tells me nothing. If you have to reach from 0 to 2K meters through a distance of several kilometers what it matters is the average inclination throughout the race. It's different to let say climb up to 2K on 40% inclination using a short path versus 8% taking a longer one.

@nikolaskallianiotis8622 Check out the whole SunTrip Route to see how it really was! More than 50k Meters of Elevation and +7500km

@@kilianweigand that agrees with what I say. But again, you don't mention the average inclination though it seems that 50Km of TOTAL elevation throughout a 7500km race makes a small average inclination and therefore electrical motors along with muscles can do the job. The sun isn't always up there and you can't have a heavy load of batteries so the muscles are the main source of energy.

happy to hear that!

yet uK must just let the all in from all over????
