Change Business Process Flow based on Data added to Form

Hi, 

Would it be possible, without Javascript, to change the Business Process Flow automatically based on data entered into a field. 

e.g. There is an option-set on the Oportunity Form with the options: 

1. Motorbike

2. Lorry

3. Bicycle 

For each of these options there is a separate Business Process Flow. When one of the options are selected, and the Form is saved, the corresponding Business Process Flow is loaded. 

Is this possible, or is Js required?
