You need to do what you think is best for you and your DH. However, you need to keep in mind how devastated you were when you discovered the bikes missing, how you felt sort of violated. That needs to be considered as well as the actual value of the bikes. Will the punishment actually serve to teach the thieves a lesson so they will never do that again? We seem to have evolved into a society that some people think that it's OK to take something from someone else because they figure they won't get caught or will get a light sentence. We as victims need to support the justice system to implement punishment that will truly deter these 'boys' from future criminal endeavors. I don't know exactly what that should be, but supporting a lesser charge may not be the answer. YMMV
Glad you are getting the bikes back,
