Thanks guys, good to hear y'll are enjoying them!

I'm all caught up on orders and have carts in stock ready to ship.
Just added a few more pictures to the album:

Including a couple with hard rubber tires, an extra cost option. These would be great in a shop on a hard floor/pavement, less good on gravel and not good at all on soft ground.
The standard motorcycle tires I'd say are the best all around choice, larger footprint and softer ride.
