Is there a bike bus from Ryde (top ryde) to the city (near central)

would be interested in considering joining one if there is
I've just started riding from Denistone to Pyrmont via Top Ryde, Buffalo Road, Ryde Road, onto Gladesville Bridge, along Vic Road to Anzac Bridge, ending in Pyrmont. 15km at an average of about 20km/h.
I'm trying to do it 3 days a week at the moment.
I pass Top Ryde just before 6.30am I think. Reverse route starts at corner of Harris and Allen Streets sometime after 5.15pm.
It's an empty bus so far, but happy to collect passengers / share the driving
