How to see observation point without a vehicle?

Hi! Me and my husband will be visiting Zion in the last week of September! We are super excited, and I'm trying to do as much research as possible before we leave to make things nice and easy, as they could be anyway :) Unfortunately we won't be able to rent a vehicle while we're there, but we will be staying in Springdale so we will have easy access to the shuttle lines. The one thing I have not really got down, is how to get to observation point. I've heard people say you can take a shuttle from Zion Ponderosa Ranch, but I haven't yet seen how to get to there- I'm assuming you have to drive, so I'm wondering if we can rent an e-bike to get to the ranch, to get to the shuttle? If anyone has any insight it would greatly be appreciated!! And if anyone is curious about the rest of our trip, we're only going to have two full days to spend there, so we'd like to do the narrows, observation point, and maayyybe emerald pools if we can swing it!
