I plan to leave my village near Grenoble (French Alps) in early May for a trip through Europe, Asia and America. I will ride East. At the moment, I don't know the exact route I will follow (at least for the first 10K km), but my target is to reach the Bering Strait, and to cross it on my bike. Once in Alaska, I will join the first roads and I will see what could be my final destination that is not very clear in my mind: if I reach the Bering Strait, I will be very happy. If I cross it on my bike, I will be even more happy. Anyway, I am already very happy to prepare this trip. I am a lucky guy. To reach and to cross the Bering Strait, I need to make my bike amphibian. So, I built a simple transmission (based on belts and pulleys) to make my engine (KTM690) powering an out-board propeller. And I forget to say that I will carry on the bike an inflatable boat that will used on water. The boat on the bike, then the bike on the boat. That's quite simple (but cumbersome). The general goal of this trip is to prove that we could go everywhere by ourselves, with a bike. At the moment, I exclude to go to Antarctica and to New Zealand, that are obviously too far for my small boat. But I would say that almost any place where the terrestrial mammals exist could be a possible destination. Our Earth is small, and all the lands are more or less connected together by relatively small straits (smaller than 100 km). I said with my bike but if I was younger, I would like to try with a push bike and an inflatable canoe... But I am already too old, too lazy, and I don't have enough courage for riding a push bike on a long distance. And I like motorbikes. To summarize this project, I can list the main issues: First I need several authorizations. I had to take a one year visa for Russia, that is not the most complex point. I am currently dealing with the Russian administration to get a special permit to cross Chukotka, the most easterly republic of Russia. A big concern: for administrative reason, I will have to leave Russia in Provideniya, that is still a bit far from the Bering Strait (but the closest place with an Immigration Office). From Provideniya, I will follow the coast for 250 km, then I will cross the strait (100km more). But in case of emergency, I could stop before crossing (case of force majeure). I will have also the possibility to have a break at the Diomedes Islands (mid distance between Chukotka and Alaska). At least at the small Diomede (the American one). On the American coast, I will have to pay the Immigration Police to fly from Nome to Wales (a village front of the Bering strait) to stamp my passport. At the end, I believe that I am going for a fully legal trip... The main difficulty is to reach Chukotka. I read on this forum a (nice) thread written by 3 Polish bikers who already rode to Egvekinot after taking a ferry on the Kolyma river to Aniusk. I will follow the exact same route, but I will try to sail with my own bike-boat on this river instead of getting a ferry. My only concern is that there are about 1100 km to sail... Perhaps I am a bit ambitious. Once in Alaska, things will not be much easier, and I will have again to sail (on the Yukon river). When sailing, I am on my bike... but I guess that it will be sometimes tedious. Between Grenoble (France) and Fairbanks (Alaska) I expect to ride around 25000 km (20000 km on paved road) on land, and to sail 2000 km (500 km on sea, and the rest on rivers). There are also some technical issues, including carrying petrol. The max distance without a petrol station will be 1100 km on (unpaved) road, and 550 km on water. I added to my original 12 liter tank a 14 liter Safari tank, and I bought three 12 liters bladders. Total=62 liters. Quite a big load for a lite bike that already carries a 30 kg boat plus 20 kg of mechanical parts, plus my body (not so light), my toothbrush, etc... Another issue is the river crossing. As read in the report of the Polish guys, the numerous rivers could be sometimes very deep... I will use my boat (without setting up the propeller) when I will feel that crossing is too risky. It could be long to inflate/deflate the boat, but safer. What else ? The KTM 690 is for sure not the most reliable bike on the world, but I am now too far in my project to change. I still have my old Yam 600TT (that is a very strong bike), but it has already more than 100k km (it has been used for a previous RTW), and I feel that I could now encounter some problems with it as well. I have also to say that my PVC boat does not like rocks, but fortunately, this concern should appear only when landing. I stop this post for the moment. If people are interested by this concept of travelling, I will try to post some messages from time to time on this forum. I know I have in several countries some good friends who read it. If you want some technical details you could find more information on this web site: www.summer-ride.com I have the project to publish all the technical information, including the drawings. I just need more time... I also plan to use my old web site (www.route-estivale.fr) as a diary blog, but this one will be in French for my mother. To see more details, you could also look at a video made by France3, a French tv channel about this project. But it is in French.
