The german version of the questionnaire was launched September 12th 2000, the english version followed November 20th 2000. The following "population" was received:
By now, there are some evaluations of separate parameters. Multiple evaluations will come as soon as I have enough time left from tandem biking. The translation process from german into english is still in progess!
Not all questions were answered in all submitted questionnaires, therefore the number n of answers is given in each graph (n = ...).

Listing of all manufacturers
Brands: We didn't know that there are or were so many brands of tandem bikes. Santana holds the pole position at about 20 % and Cannondale is well established on the second position. KHS and Stevens are relatively new in building tandems but are really good in filling the mid-price segment. Some brands are predominantly selled in Europe like Gleiss, others are ridden only in the US like Co-Motion or Bilenky.
Listing of all manufacturers
Brands since 1998: Brands of the tandems which were purchased since 1998.
Prices: Retail prices as given by the owners. The two statistics do not overlap.
Satisfaction: Teams were asked if they would buy the same tandem again (yes/no), if they were satisfied with it right after purchase (1: very satisfied, 4:very dissatisfied) and if they are satisfected now, after possible changes (1: very satisfied, 4:very dissatisfied).
Field(s) of use: There were some categories to choose from, and more than one could be selected. A category "Commuting" was not asked, sorry.
Trailers: Surprisingly many tandem teams are using trailers for luggage or children transport. For their children some teams are using trailer bikes or stokid additions.
Maximum speed: The distribution of the maximum speeds as given by the teams. Some maybe misunderstood the question and gave averaged values.
Team weight: Distribution of the team weights, including triplets and quadruplets as well.
Tandem weight: Distribution of the tandem weights, including long vehicles, too.
Frame geometry: Stoker's horizontal top tube length.
Mileage: What the teams said they rode on the bike during the last 12 months.
Pedals: The types of the pedals at the captain's and the stoker's position. At the stoker's position their are slightly less clipless pedals.
Wheels: Wheel diameters, number of spokes of the rear wheels and the frequency of spoke failures.
Drive train: Numbers of teeth of the big chainring.
