Help - Motobycle

Hello , I’m from Brazil and I really need your help !

I’m using a Google translator because my English is bad

I take a lot of you because I need help deliver this prototype for my college team but do not have much knowledge about Unreal and everything I try to do is going wrong , I will be leaving a link here to download the prototype of the project that have to do

The prototype is simple , need to create a physical and basic controls for a bike but it seems that does not work … = \

If anyone can help me I appreciate if you can not also appreciate the way for attention

Signed, Allan
