I'm looking for a used adult tricycle. I am just too clumsy for a regular bike. If you get any info about one, please PM me, Lollykay.
I think you should visit the bike rental places. I'll bet you can work out a deal with them. But how will you manage their disappearance? I think I'd rather give my renters a subsidy at a rental company, and not have to deal with the complaining about details.
Thank God we have built a new home that we will not rent. We no longer have to hold our breath when we arrive at our home before surveying the most recent damage from renters.
