bike height
i'm planning on designing a tandem bike similar to the one used by
these guys www.steppebysteppe.com.au but was wondering about how to best setup the bike to get maxmimum clearance without a loss in stability, i have had a play with some bikes (not like theirs) and even going over a few small logs it seems to bottom out, how high up have people had their recumbents raised before? thanks -rob |

"rob" wrote: > i'm planning on designing a tandem bike similar to the one used by > these guys www.steppebysteppe.com.au Wow!! Had a look over this site. My first thoughts were about the craziness of trying to ride a quad-bike, with all it's complexities, across Asia. Then the bit about carrying up to 500kg!! And the idea of making it amphibious. Hope these people haven't bitten off more than they can chew. Weights of this order are not the sort of thing to be pedalling under human power, and the central Asian mountains will be steep, with rough roads and scarcity of supplies. People have done this sort of trip, but on regular bikes, maybe assisted with BOB trailers, and more lightly loaded. I see great difficulties pushing that quad. And a fairing to prevent frostbite? Correct me if I'm wrong, but frostbite is really about a bit more than wind chill... something about the - 30 deg temps in Siberia?? Even still conditions, especially if you get compromised circulation, will produce frostbite risks. Then I chaecked out the bike specs. Put together by Greenspeed, well they have got some good help there. Still I'm not a recumbent afficionado. Every ride I've ever been on with the Greenspeed trikes I've only ever encountered them in one sitiation - going past them! The Steppe by Steppe team is more interesting. Roger Chao, bushwalking Federation Peak, crossed Greenland, Australian Geographic young adventurer of the year.... hmm, impressive. Megan Kerr... ??? (thinks: "I know that name?") Omigod, an ex-student of mine!! There's her picture, yes! And reading her background she's doing a lot of cycling. Wow, Megan has come a long way. Can't recall if she ever did the GVBR with our school, don't think so, but she sure seems to be a convert to cycling. Well, I wish them all the best in their expedition. Might send them a message. I hope their chosen vehicle proves effective on the vastness of Siberia. -- Cheers Peter ~~~ ~ _@ ~~ ~ _- \, ~~ (*)/ (*) |

It is getting or building a workable diff that is the problem, unless you walk it through all tight curves. across Asia. That is like three times across Australia, or is it four? > Then the bit about carrying up to 500kg!! Two people(?). No problem. Have people forgotten that guy towing a ton(?) around the USA as his bid for the US olympic team? > And the idea of making it amphibious. Well, you are going to need that to cross some of the waterways, unless you wait for a friendly truck to come by as they did on the Peking to Paris recreation (ABC, Warren Brown) > Hope these people haven't bitten off more than they can chew. Weights of > this order are not the sort of thing to be pedalling under human power, So long as you are not worried about the speed. It is the braking that terrifies me. > .... Australian Geographic young adventurer > of the year.... hmm, impressive. Naah. Aus Geo thinks being the 1,001st person to ride a push bike up Cape York is adventure. There was even a printed guide around at the time put together by a guy who ran commercial bicycle tours up there. > Well, I wish them all the best in their expedition. Might send them a > message.
