Translation:I have a bicycle, I do not need gas.
Good example of the sentense where the "у меня... " construction is used without "есть".
please permit 'fuel' here in addition to 'gas'. It is getting increasingly frustrating that my errors here more often are due to duolingo's idea of what's permissible in English is not the same as mine (when mine is in no way wrong), than any actual problems with my knowledge of Russian. The fact that many problems actually consist of duolingo getting English constructions wrong, and that problems are being dealt with very slowly, makes it a rather frustrating experience.
