Does it include the bolts as well as the knobs?

This kit includes just the knobs.

What parts are in this hardware replacement? I need the two knobs that go on the handles to adjust the height.

The hardware kit comes with 4 knobs and 4 C-Clips.

My carrier bag on the three wheeled walker is falling apart. How much is a new bag and how quickly can I purchase one? I am on my second 3 wheeler and really love it. Just needs a new basket and would also love a tray, if you make one for this item.

Unfortunately, we do not currently offer that as a replacement part.
