When coming from the Ashlu side, the first big bushwack is on the west side of Pokosha Pass and down to Clowholm River. As far as I can tell, thiat is still a bushwack. And certainly not bikeable.
Another section that is a bushwack is the part going over Polytop Pass, from Rainy River Road to Sechelt Creek. See 49.631784,-123.537826 to 49.6472,-123.5444.
You can find lots of references to the complete "trail" on google and facebook. Here is a report from September 2016 where a pretty tough girl called Anwen Roberts attempted to go from Ashlu to Clowholm in 3 days. She did pretty good, but her description of the bush thrash once over Pokosha pass is exactly what I would expect. See Anwen Roberts Report.
If you really want to see firsthand the "beyond Pokosah Pass" section, I recommend the bike and hike trip we've done a couple of times up Sigurd Creek, around Sigurd and down Pokosha. See Sigurd-Pokosha Hike and Bike Loop - Again in 2015.
