Pushes hard forward or backward, a lot of resistance, when handles are turned but not hard when straight. Also the whole bike will start to shake if I have the handles turned all the way to the left and try to push/pull. Seems to start in the front. It takes a lot of effort to move the bike on flat ground when turning at all. There is no chain on the bike yet so I know it's not drive train. Also I bought it and they had already started to turn it into a bobber. I'm new to bikes and I am not sure what would cause this. Attached a picture I don't know if that will help or not
