I am very satisfied with this wheelset. It comes with tinned wires that need to be soldered to the motors. There are good mounting blocks and screws to mount them, but I found another way to mount them. The motor fits snugly in the 3/4" hole and I found them easy to install. I tested the motors with a nearly dead AAA battery and it ran on low current. The motors appear well made and durable. The Tires are soft and I think they will have good grip I would definitely buy again.
