For our customer Damtours we have developed a custom power-assist system based on 2 Bldc Hub Motors (Magic Pie 1000Watts). The beerbike is operated by a designated driver who controls the drive system, the passengers are pedaling. The conversion appeared to be a huge succes. The electric powered beerbike is also used in several other European countries. We have already successfully converted 7 beerbikes for Damtours.
