All told I've got about 40,000 miles of bicycle touring under my belt. I started, whena lot of you guys were contemplating this as an option, when I was 14 and the. Just never stopped. And while I've never really dedicated my living arrangements to permanently live from the saddle, there have been some very protracted periods where that's all I lived from. It can be done, it will make you change some things in your life, you will probably enjoy it.
Concerns:
1.) Getting access to locations off main roads(even fire roads)...can't exactly lug all this stuff through the brush.
In the west this is a lot less problematic tha you might imagine. The further east you go the more problematic it becomes because of the lack of public lands. Just so you know, you can lug all that gear around. Many people lug it through some very challenging places. Remember that the bike is carrying the weight, not you.
2.) Safety/security. Someone could much more easily come by during sleeping hours(or whenever) jack stuff and throw into back of pick-up and off they go.
Start by always assuming the best about people. Someone could come by your house and load whatever they wanted into their truck at any time too, but that rarely happens. One of the nicest things about living from the saddle is that in doing so you eliminate many of the physical and social walls that exists around people in cars. Imagine yourself on a beach in SoCal and someone approaches you while you're cooking dinner. They've seen your bike, probably your camp too. Ninty-nine times out of a hundred they're interested what you're doing. Maybe they share your wanderlust? Maybe they're curious about who you are, where you've been, or where you're headed? Now is your opportunity to invite them to experience your life for a moment or two, if you immediately assume the worst about them they'll retreat and it will put them off of cycling.
Assuming the best of people often disarms those with negative intentions too. Your friendly smile will open them up to their curiosity thereby protecting you far more effectively than brandishing a weapon. That said avoid places you know you'll get into trouble.
3.) Broken rims/other equipment out in the boonies...can't really carry a ton of spare parts. Triple AAA won't tow me...lol.
It's pretty darn easy to become a very good bike mechanic. That said the single most important thing you can do to prevent a catastrophic failure is regular bike maintenance. Keep your drive system clean and well lubricated. Make sure you clear off dirt build up from moving parts and friction surfaces (think rims for friction breaks). Look at your tires ans replace them when they get worn or cracked.
If all else fails you can usually get a ride from a passing truck to a town with a bike shop for free.
Other things to think about:
1) getting sick on a bike sucks donkey balls. Have a plane for dealing with sickness, because if you're on the bike full time you'll need one eventually. I've had to recover from the flu while on tour on my own. When I was overcome with the symptoms I was in the boondocks and so I got my camp set up as best as I was able and then forced fluids with ample amounts of ibuprofen to break the fever. Listen to your body, it's what moves you around.
2) Are you dropping out for a while or just riding around the edges? If your dropping out you won't have an address or possibly even a phone number unless you think about how to deal with that. That's actually pretty cool way to do it IMO. Most of humanity throughout history lacked either address or phone number, but if you get good at locating free wi-fi you can still stay in contact with friends and family.
3) Recumbent or not the pace of your life will be about 12 to 15 MPH. Man I've ridden wall, even have a velomobile out front, but if you're peddling around 75 to 150 pounds -- your house on two wheels -- there will be precious few moments where you'll be able to exceed that speed range. And plenty of times when you won't even get there. Get comfortable with this and don't bust your ass or break your bank trying to exceed it. You won't regardless of the expensive, fancy gear you buy or endless hours in the gym.
In fact, don't go to the gym and ride the cheapest bike you can reasonably get away with. Then your fun to mile ratio will improve and you won't be walking around like a clown in spandex.
4) Beware of hidden agendas. Someone else posted a recommend for Darren over at bicycletouringpro.com. Darren is an awesome dude, but, land this is a big but, look at his website and all the pictures of him. This is a guy that has predicated his financial future and current well being on that sharp, well- maintained website and a shaved mug every morning. This means that he spends a lot of time working on that stuff instead of the bike trip he's currently supposed to be enjoying. Imagine trying to get a phone signal in the middle of Ukrain so you can discuss sales strategy with a sponsor.
Years ago, while on a tour, I ran into a guy from Australia, and this encounter guides much of how I tour today. He was headed south on Hwy 97 in Washington, I north. He was on his ninth year of touring and his first North American visit. He was riding a crappy bike with true wheels and 4 gallon buckets for panniers. He hadn't showered in a week, but the smile on his face was intoxicating. We stopped to talk, as tourist will do, and ended up camping the night together. During that night I got to hear a bunch of amazing stories and came to understand his agenda as it was. "Go south for beer and warmth during the winter, come back north when it isn't so cold. Meet people." Let me tell you, this IS the way to do it.
5) By now you've probably already left, but I'll include this one just so others will see it and hopefully learn. You can't condition for a tour. Sure you can ride your bike before you leave, and this is all well and good. Bt to become the motive force in your daily life, there is no substitute. You just have to get out there and keep spinning, mile after mile, day after day. If you ride like you're getting ready to race, that's what you'll be ready for when you start your tour (and you'll blow your energy and bonk because you're ready to race). Same goes for just about everything else. The only way you'll be ready to tour is if you tour.
6) The Zen of bicycle touring is being able to cope with A-hole drivers. I used to get angry, used to chase A-holes down, used to scream and carry on, used to moan about how I'd been wronged, used to film them and then take it to the cops, used to. That never got me anywhere but angry.
Today I understand that there are A-holes on the road, they will probably pass me to close. From time to time they may even throw something at me. That not why I'm out there though, to be angry, and each one of those events is just an opportunity for me to deal with that wild emotion. Identify it, let it pass, and keep spinning.
Hope that helps and maybe I'll see you out on the road.
