The Pennine Way is largely footpath, and therefore there's no ROW for bikes.
The Pennine Bridleway is a bit of a mix. Some bits you could ride on 28c tyres, other bits you'd be better off on an MTB with some form of suspension.
The Great North Trail follows quite a lot of it. Cycling UK have put together some route sheets which can be found on this page: https://issuu.com/ctc_cyclists
Each section is pretty well described in terms of likely terrain.
