At present, we cannot provide precise or complete figures for the CO₂ footprint or total energy required to manufacture a TWIKE vehicle. A full life-cycle assessment depends on complex data from multiple suppliers, which is not always fully available.
However, a key factor in the environmental impact of any vehicle is its overall weight and material usage.
-
The TWIKE 3 is significantly lighter than conventional electric cars.
-
The TWIKE 5 has an approximate vehicle weight of around 685 kg, which is still considerably lower than most electric vehicles in its class.
Lower vehicle weight generally means less material required for production and lower energy demand during manufacturing, as well as improved efficiency during use. While this does not replace a full CO₂ assessment, it provides a meaningful comparative indicator.
