The G4 Bike was introduced and was featured on the Laidback Bike Report of July 11, 2021.
That presentation can be viewed at https://youtu.be/5YVGB8RZ31o starting at minute 34 of the program.
The presentation charts I used are provided below.
This video shows the basic operation of the G4 Sport. Including the input of supplemental hand power. Note that supplemental hand power is applied by pulling the fork mounted crankset into the pedal thrust.
