So I have a new project regarding an electric bike and I am trying to find a replacement transistor haven't had any luck with the code anyone have any advice or tips?
It's often that it's the case that it's a Chinese transistor and that in thows cases the 2S prefix is missing. So without a schematic I'd say your looking for a 2SD49E.
As Lightium says Japanese (not really Chinese) transistors commonly start with 2S which isn't shown on the casing - however, a 2SD49 is a metal TO66 power transistor?.
