I was watching an old episode of the Monkees from 1966. In the theme song they are riding what looks like at first glance to be skatebikes.
I found a page on The Cabe: I’m Looking For Information About “The Monkees” Unicycles

AXL Skatebikes appear to be a rebranded MAX Skatebike. A chain guard is added and the labels are changed. Both use a 12″ plastic wheel.

An auxiliary device of a monocycle has an auxiliary body connected to a monocycle. The main fork of the monocycle has a main sleeve. A detachable auxiliary body is connected to the main sleeve. Thereby, the auxiliary body can be installed to or detachable from the monocycle. The auxiliary body is mainly formed by a front head and a frame tube. The front head has a handle frame, a sub-wheel body and a sub-fork. The frame tube is connected to the monocycle. A front end of the monocycle is installed with a sub-sleeve which is formed at an upper end of the sub-fork so as to be formed as a monocycle with an auxiliary wheel.
A skate bike including a frame; a spring seat saddle connected to an upper part of the frame; a wheel having a central axle connected to a lower part of the frame; a pair of pedals provided on either side of the wheel; a pair of supporting shafts pivotally provided on the frame at suitable position to define a support for feet of a passenger; and an auxiliary wheel set provided on the frame at a suitable position. The skate bike is effective as an unicycle and also effective as an ice scooter or a grass scooter when used in conjunction with a pair of ski poles.
A new and unique wheeled vehicle comprising a unicycle-like device. The device employs the same general elements as a unicycle including a single large drive wheel, a pair of pedals, a seat, and a pair of forks to support the seat. Attached to the rear of the device is an additional set of support wheels. The support wheels are attached through a support frame which extends generally rearwardly and downwardly from the center of the drive wheel. The support wheels are attached to one another by an axle, which is in turn attached to the support frame in such a manner that the support wheels pronate and track through turns as the drive wheel is turned to the right or left. Under normal conditions the support wheels remain on the ground at all times. This device provides the rider with additional longitudinal stability without adding a significant increment of lateral stability.
This invention relates to a roller bicycle having rollers rotably mounted on the front wheel shaft and a single rear wheel for a common use as a sporting and playing apparatus on which one can ride forward and backward by keeping his balance, thereby improving his agility and developing his physical strength.
While exploring the history of the Minson skate bike I found the original US patent for a “Roller bicycle“.

The original patent for the Garel skatebike. The Garel patent was granted on Nov 29, 1983. This patent is the basis of the Garel, LeRun and Max Skatebikes.
A velocipede having a single driving wheel which is powered by rotating pedals that rotate a sprocket that is connected to the driving wheels by a chain. A roller assembly comprises small diameter rollers having a roller axis that is disposed lower than and in front of the pedal axis. The rollers are connected to the velocipede frame by a bearing member so that the rollers can be articulated allowing the rider to lean on the velocipede thereby controlling the direction of movement.
