Two wireless stereo speakers and a frame lighting system with five ambient modes and two that sync to music make this a bike aimed at riders who want to be seen and heard on an evening commute. Shifting is 6-speed Shimano twist-grip, which changes gear without moving the hands off the bar. The frame fits riders 4 to 5 ft tall from about 13 years, with the saddle between 32 and 37 in and a 220 lb seat rating. It arrives 85% pre-assembled, weighs 33 lbs and charges over the USB-C cable supplied.
