I think the DC AI is the most helpful with answering more straightforward questions. For example, on DC every once in a while there's a question on converting dates (for example): https://community.intersystems.com/ask-dc-ai?question_id=129616

Most short questions like this can be answered by AI and if the answer is wrong than it's worth posting a question on a Developer Community.

First of all, there are no links to docs you've tried in your post. If you add them (or the code from them) it will be easier to understand what you've already tried.

In general, I believe the easiest way to insert data in your case will be to use SQL. You can either write something like 

insert into JASON.BikeDB (Make, Model) values (:make, :model)

and pass the values of parameters.

Or if you wish to use your class method, you will first need to add a modifier SqlProc to it:

ClassMethod SaveNew(Make As %String, Model As %String) [SqlProc]
{
    Set obj=##class(JASON.BikeDB).%New()
    Set obj.Make=Make
    Set obj.Model=Model
    Set sve=obj.%Save()
}

and then call this as a stored procedure:

begin
   JASON.DataBase.SaveNew(:make, :model);
end;
