DescriptionSvea-cykel prototyp 1892.jpeg |
Svenska: Herrcykel av typ upp-och-nertrampare (till skillnad från rundtrampare). Upp-och-nedgående pedaler med kedjor till baknavet som är en s.k. rullspärr enl. Birger Ljungströms konstruktion, patenterad 1892. Rullspärren ger frihjulsfunktion. De fram-och-återgående kedjorna ger baknavet en roterande rörelse genom två excentriska "drivskivor". Fem tryckluftsreglerade växlar. På styret finns två gummiblåsor dolda under metallhöjle. Luften leds med slangarna till ytterliggare två gummiblåsor placerade på segmenten vid tramporna. Broms på bakhjulet genom att de båda tramporna trycks ned och påverkar en hävarm som trycker två roterande koniska bromsklotsar mot bakdäcket. Senare modell hade s.k. skedbroms mot bakdäcket. Framhjulsbroms med s.k. skedbroms mot framdäcket. Fälgar och skärmar av trä.
