Understanding sizes and measurements
Height ranges are reported by the manufacturer. A matching range is a starting point, not a guarantee of fit. Your proportions and bike setup also matter.
Reach is the horizontal distance from the bottom bracket to the top of the head tube; stack is the vertical distance.
Positive values mean more reach or stack than the reference size; zero means the same measurement. Missing values are not estimated.
Size
Geometry not published
The manufacturer lists these sizes without frame measurements, so there is no drawing or geometry table.

Total gear range309%
These speeds describe the gearing at the selected cadence, not how fast you can ride.
Calculated from published gear-inch values and their wheel-size assumptions.
These gearing values describe the bicycle, not a selected frame size.
A 100% range means one ratio; 500% means the highest ratio is five times the lowest.
For e-bikes, motor assistance cutoff is not represented.
Gear-inch range
Lower gear-inch values travel less distance per pedal revolution; higher values travel farther.
