Nice one brother!
I love bike adventures...its a great way to explore and be with the nature.....
Just an observation...would not be easier to build up a fitness lvl and use regular bike rather than carrying all those batteries and solar panels? Also you could use skinnier tyries which would make cycle much easier.....
Ive done about 450 km adventure on my gravel bike over 3 days period with about 25kg of extra gear...i know that might be a bit extreme for some people...but doing around 100km with some weight its not a such a big effort...you could build your fitness up to that in 1 season....
just a thought you know...

In Lak'ech!
