Lighting and sound set this 20 inch bike apart: a seven mode frame light, a bright front lamp, a seven color rear light and two wireless speakers travel with the rider. Shifting comes from a Shimano rear derailleur with six speeds, and treaded 20 inch rubber wheels handle mixed terrain. The carbon steel build pairs a rear drum brake with a front caliper brake for controlled stopping, while the softly padded saddle and adjustable handlebar help riders find a comfortable posture. Non-slip pedals, reflectors and a bell are fitted, and the bike ships about 85 percent assembled.
