So around 5 month ago I suddenly needed bicycle and went to bicycle shop called Asahi, thing is after purchasing it I immediately started to notice that it’s not picking up speed at all if I stop pedaling for 5 sec it starts to lose speed rapidly and feels like I’m dragging a rock behind me. Now it’s starting to cause knee joint problem for me because of constant pedaling, did I buy the wrong type of bicycle or all Asahi bycicle like these any had a similar experience like this?
