Hawke's Bay Solo Wine Recommendations

Hi all,

I'm planning a trip to Hawke's Bay and have a few questions I'm hoping someone can give advice on :) I will be in HB for 3 nights and going between Havelock North and Napier as my base. I am also a solo traveler and wondering how to go about getting from winery to winery. I know Frankly's has been recommended but they are a 2 person minimum. I also was going to consider renting an ebike through a company like On Yer Bike but they go to wineries not on my list. Anyone have any recommendations for a solo wine tour I could use?

Wineries I'm hoping to go to are: Craggy Range, Te Awanga, Mission estate, Sileni, Gimblett Gravels, Black Barn, Askerne and Te Mata.

Thanks in advance!
