They use the same concept (solar panels providing shade) for certain plants! I think tomatoes are the first it was done with. The leaves and vines can spread out and get enough sunlight, while the panels keep the edible part in the shade! It increases the amount of tomatoes while using less water. So theoretically, I'd expect to see the same thing with this bike! Obviously you can go farther with electric, but with this bike you could ride even farther (sweat less, and not run out of water) due to the shade than you could ride if you were sweating in direct sunlight

From Denmark: Thank you so much for this excellent, very descriptive and instructive video. I have been following your Sun Tours and enjoyed them a lot. Congratulations for your endeavours. I am 80 years old and avid of long haul Biking and triking. No EL Assist. Until 4 years ago I used to ride a KOGA bike + a ZIFLEX trailer for my camping gear. Then I shifted an ICE SPRINT FS Trike 20" wheels + the ZIFLEX TRAILER in tow... Last year I triked from from Ebeltoft (Jutland-DK) to Frederikshavn (N-E coast of DK)-Ferry to Gothenburg- Triked to Stockholm -Ferry to Turku (Finland) -Triked to Helsinki - Ferry back to Stockholm -Triked along the East Coast of Sweden to Nynäshamn - Ferry to Visby/Island of Gotland - Ferry from Visby to Oskarshamn - Triking to Ystad (South of Sweden - Ferry to the Danish Bornholm Island - Ferry from Rønne (Bornholm) to Køge (South of Copenhagen) - Triking again and Ferrying to Falster-Loland-Langeland-Ærø and Back over Sjælland Odde to Ebeltoft. I carry 65 kg of gear + my own weight (starting with 112 kg, finishing at 94 kg...). I am thinking about getting EL Assist for a coming trip to Turkiye (Turkey). Will be immensely grateful for the names, eventually web sites of the companies that produced the parts for your rig. 🙏

Wow, this really is one efficient piece of kit. Nice work Jack. I guess a very efficient mid drive would save some watts, but on the other hand brakes would suffer more and there'd be no regen and all wheel drive. Do you have a guesstimate of how many watts you've regened during the Sun Trip? A very light aero tail and front fairing is what also comes to mind for squeezing out the last efficiency. I guess cutting and gluing XPS foam to add a teardrop tail to the poles and anything else exposed to the wind would also work. Anything counts in such a long race where going 1% faster would save you almost 3 hours haha.

I'm not sure you could make a mid DriveMode to more efficient than a direct drive. On a very mountainous route, then yes. But on this trip we spent 3 or 4 days on the flat going down Morocco. Some of the best day. S I'm not a 100% sure, but I think I'd like 250 to 300 W/h of regen. When there is no sun. It can be a 100% of your energy for the day. Yes, I think a lightweight tail would be a fantastic upgrade. More cautious on the front, as it's hard to get it right and also you're affecting the cooling of the rider.

I rode my bike a couple years back in April to try to get some traction for my distributed protocol (still working on it!). I ended up going from San Antonio to Albuquerque before running out of $$$. In my limited experience, in Texas and New Mexico I would say that the sun was definitely the most dangerous part...well that and the damn semis transporting windmill blades (they're insanely big and suck your bike sideways). So I love the idea of the solar panel for shade. I love this whole idea really and if I had money I'd definitely be cleaning up this design to make it a "real" product. In fact the distributed protocol is for semantic versioning (it's very similar to git under the hood, but a more powerful generalized design), so we could dogfood the protocol to version control + evolve the design, similar to how people collaborate on open source software.

Amazing video Jack, great design. Sure you can always improve but what you have seems to be a perfect compromise between efficiency and simplicity. You don’t want parts which are too difficult to fix. Yeah I’m really impressed with the 100W power consumption for the motor, on my RH212 (direct hub drive), I would need to go to 150 or 200W to feel a “real” push, 100W seems to do close to nothing, at least at 25Km/h, but that might be due to motor “winding” speed (rpm / v). I’ll have to investigate. which Hub motor is it? Being relatively small, you didn’t get regen heat issues on the long slopes down? You mentioned 25Km/h, but on a standard flat road with no wind, were you not around 30-32? Did you have variable regen? No throttle for quick dog escapes? Last questions: the solar charge controller, which one was it? Thanks and very much looking forward to this Azub tour guide!!!

Yes, you don't feel much around 100 W, but it's there and your average speed will show it over the day. Over 30 km per hour is too fast.

You must have been keeping an eye on the next days weather to be confident that you can use ‘todays’ power knowing that you can/cant recharge the next day.

(451 is the bmx racing one, 406 is for the people doing tricks) 5 would having someone on the motorcyclist doing shopping for you hours ahead, while in constant communication, be outside the spirit of the rules of this being self-supported? this would make it possible to make every day 13 hours and 55 minutes long. no bathroom breaks, wizz out the side like grand tour racers do. 6 does anybody carry an entire spare wheel? mid drive motor, standard wheels, and maybe even making the front and rear wheel on the same rear hub like surly used to do on their ridiculous adventure bikes with a custom wide fork, would make it possible to just swap an entire wheel out and do puncture repair after hours. maybe even 2 spare wheels. if they're in a tight lycra bag they don't drag on very much and can be put in the wake of the bike, almost lengthening the tail end, which could even possibly improve aerodynamics?

I spent no time in a day repairing something. The panels are already closer to ambient air temperature than usual beacuse of the air cooling of the bike moving forward.

I'm not sure it would be worth the weight for me. Most people want to use hubs motors and not as light as mine so you would be carrying and extra 4 to 6kg that you probably wouldn't use.

310w Nice. I love your setup. I have a 200w trailer. Jack stop by and check out my solar trailer, and let me know what you think. Long live the solar tour!

It feels similar to a roadbike with deep section wheels in the wind. The bike is heavy, so resists being moved. But for sure it's annoying, like on a road bike

Very interesting. However, I am uncertain if directing the panel helps really so much. Having it horizontal all the time gives already 85% of the maximal collection of sun energy (calculated for a all year round solar system, in summertime probably more). This would also save considerable weight and costs and result in less mechanical failures. However, during winter a tilting system is probably considerably better.
@JackButlerVideos4 ай бұрын
2 things made the tilting worth it for me on this sun trip., it's earlier in the year like you said. And it's also a North to South sun trip for the first time.

@@JackButlerVideos Ok, I understand. What's the maximal velocity the motor supports? 25km/h or faster than that?

Good design concepts ... !!! Erm as far as video goes ... invest in a bluetooth lapel mic , as when you are far from mic on camera , your audio is hard to understand . Front mudguard , wires getting wet ... mudguard causing wind drag and hard to access for punctures .... Why not get something of a U shape ,but face towrds wires , so wind can flow over , and the u channel can deflect water ,coming from front wheel ????? Which could also be attached to wired assembly

Yes i need a new microphone, mine broke on the first day. Not a bad idea for the mud guard. Thanks

Cool video. I recently did a 8 day tour about 30% gravel roads and by day 7 I was so tired. Day 8 I could only get like 125bpm, I couldn't push myself any harder it was really weird. What kind of training did you do for the suntrip?
@JackButlerVideos4 ай бұрын
Yes without being trained or pacing properly thats guaranteed to happen. I trained for six months working up to around 20 hours of cycling a week. Mostly zone 2 teaining and some intervals.

Nice setup and very interesting. What kind of distance per day are you doing ? How much of that is on electric power ? I’d love to do something like this. Also do you get chafing anywhere (or did you and you resolved it) ?

Congratulations Jack!!, I have followed the Sun Trip 2024 and it has been exciting. I would like to know how much energy in kWh you have recharged with the module during the entire trip, thank you.The bike setup is very good.

I have since 2012 trike from Bikerevolution with a Motor from Sunstar but de Akku is damaged since some years and I cant use the Motor anymore. But my dream was alwas to Power it with solar, but dont know how. First i need a new working Akku.

Excellent looking bike. Just one question; does the solar panel act like a sail in moderate to strong breezes, or can it be compensated for?

Have you ever considered removing those tubes guiding the chain (totally or partially)? Should reduce friction.

I forgot, you could use a silent Stirling engine powered by a fresnel lens of the same dimension or rather 4 lenses and 4 silent stirling engines. Simpler solar powered vehicle, all thermal-mechanic without electronics
@markifi3 ай бұрын
stirling engines don't have any torque and aren't too efficient. my guess is 1% of the energy at the wheels compared to this setup with the same surface area
