Hey Joe, The road from Akatarawa Saddle in should be pretty manageable on a bike, its steady but not really steep any place - and Renata hut, though basic is a much nicer place to stay than Waiotauru (which is just an old bulldozer shed). I've been to both, though not done the track in between - it must be pretty good though, as last time I was ...

Located on Renata Ridge not far from Maymorn Junction. Sleeps: Around eight on one platform. Heating: Open fire. Camping: No.  Renata Peak is worth camping on though for views similar to Elder hut.
