Made in Italy, the SZ Bikes Equilibrium Anthracite Black Edition offers sleek, modern styling combined with a lightweight build for an ultra-smooth ride. It uses carbon fiber at the front fork, flexible plastic on the unique Spyder saddle and aluminum on the frame, rims, pedals, handlebar and seat tube, all conspiring to keep the overall weight down. The two-speed system automatic gearbox delivers an optimum gear ratio, and the hydraulic front disc brake provides quick and controlled stops in any weather condition. The all-black coloring is accented with a choice of bright color accents on the rims, while a built-in anti-theft device — complete with a 120-decibel siren — ensures no one can steal your eye-catching ride.
