One of the advantages of the mid-drive frame of Avial e-Bikes is that it can be fitted with a drive from almost any manufacturer. Now this mid-motor model is equipped with a COMP C17 250 / 350W drive, which in 2019 was chosen by us as the optimal price / quality ratio. However, if necessary, the mid-drive motor of up to 500W can be mounted on the frame, for example, produced by the following companies: Bafang, Bosch, Shimano, etc. Other Avial e-Bikes models can be equipped with rear-hub drive from 250 to 1000W.
