AIRLINE USE TANDEMS (3 pieces): Separates the frame into 3 pieces or sections so it will fit into airline regulation size checkable luggage Probably 95% of the tandems manufactured or retrofit with S and S Couplings are configured in three sections for airline use. This method normally requires the use of 6 couplings.
NON-AIRLINE USE TANDEMS (2 pieces): Separates the frame into 2 pieces or sections so it will fit into a car, boat, train, private plane, apartment, hotel room, elevator, stairway or other confined area where a full size tandem frame wouldn't fit. This method normally requires the use of 3 couplings.
TRIPLET, QUAD, QUINT AND HEX (bikes will handle 3, 4, 5 or 6 riders) These bikes are designed to handle more than two riders and they [URL=http://www.sanling-cn.com ]use couplings[/URL] so they can be made small enough for airline or non-airline use, depending on the customers needs. Since these bikes are so specialized, they won't be covered here. If you are interested in a three or more person bike, we recommend that you study the triplet and quad photos on our web site and then discuss your options with a builder.
CONVERTIBLE CONFIGURATIONS (variable number of riders from 1 to 6): By building a bicycle with sections that can be either added or removed, a tandem or single bike that can accommodate from one to six riders can be built. Since this technology is so specialized and complex, it won't be covered here. If you are interested in a convertible, we recommend that you study the convertible bike photos on our web site and then discuss your options with a builder.
