There’s already a long history of bike touring and bike camping. The US has a national Bike Route network for this. Adventure Cycling Association has route maps.
I went on a 270 mile bike trip with my family when my kids were 5 and 8.
With the Warm Showers network, bike tourists can get free housing.
And now apparently you can buy a solar powered trailer to tow behind an e-bike if you wish and can afford that.
Yo if your solar was enough to charge the bike consistantly this would be a great solution for differently abled people everywhere. Im ready for the ebike rv fad
They help, but even in full sun with a decently-sized panel on a trailer you'll still only be slowing the battery drain. If your trip is long, sunny, and has no access to the grid, then they can make a lot of sense, but if you have any grid access at all, a second battery is usually a better choice.
Backpacking and bike is already a viable option in my country and it is the holidays I like the most. And I feel like it is more and more popular (my girlfriend job is to organise horse hiking for multiple days and it is awesome). Not going on the other side of the world but living even greater adventure nearby.
There's a small park near my house that cannot be access from the street without walking across its parking lot. No sidewalk or trail entry, only a driveway.
I live in a car-dependent area, but luckily, there is a park about 20 minutes' bike ride from my house along decently safe routes that's right on the shore of the local lake. The downside is that, since you have to cycle downhill to get there, you have to cycle uphill to get back home. Part of the route to get to this park also goes through a small industrial area, with a bunch of truck entrances and an oil refinery.
