The electric bicycle became transport means that were environment-friendly because of not dismissing gas emissions discarded so as to be classed as the vehicle without emissions. This research aimed at knowing relations between the attitude towards the environment and the interest in buying the electric bicycle. This research including in the quantitative correlation research that is relations between the attitude towards the environment and the interest in buying the electric bicycle. The sample in this research was some electric visitors of the bicycle shop. The taking of the sample used the accidental sample technique. The characteristics of the sample that was used were the respondent who learned that the electric bicycle was the environment-friendly product.

The data kind that was used in this research was the interval data. Was based on this matter then the statistical technique that was used in analysing the data that was received is Product Moment correlation. Was based on results of the research could be taken by the conclusion that there is positive relations and very significant between the attitude towards the environment and the interest in buying the electric bicycle. This was shown with the value r of 0,807 with the level of the significance 0.000<0.001. Thought r of 0,807 showed that increasingly positive the attitude towards the environment then increasingly high the interest bought the electric bicycle. On the other hand, increasingly negative the attitude towards the environment then increasingly low the interest bought the electric bicycle. The effective contribution the attitude variable towards the environment towards the interest in buying the electric bicycle of 65,1%, whereas 34,9% the rest of them were affected the other variable that was not researched.
