It appears that Juiced Bikes is now offering three frame sizes for this bike, Small (16.5"), Medium (18") and Large (20"). However, when I asked Juiced a few days ago whether all sizes would ship in the next batch (July 2017), the answer was that only the Medium frame would ship. Nevertheless their shopping cart will accept choosing any one of the three sizes. (I did not go through and actually order one, so perhaps there might be a warning after placing the order for a Small or a Large that it would not ship until later in the year. It appears my credit card would be charged immediately, not upon shipping. That's why I did not pull the trigger.) Maybe this is Juiced strategy to gage interest in Small and Large frame sizes. I hope they do in fact follow through and actually build Small and Large frame sizes, as they have done with the CrossCurrent, for example.
The other good news is that the suspension fork is now standard equipment (as is the LED headlight). MAC motor, high torque, hydraulic disc brakes, torque sensor, bigger batteries, Grin Tech charger, rear rack, and fenders are extra.
