The new HOT Gravity Zilla is just the bike for the rider wanting the performance of an aluminum frame, wide gearing, comfortable riding position and dealing with a budget.

This Gravity Zilla is monstrously capable!

Versatility, Options, Fun…run road approved wheels and tires…even run full on 1.75″ 29er rubber. A jack of all trades…own one bike and go almost anywhere, all in the same ride! …tailor made for such adventures.

Utilitarian Rig: …work horse bicycles…from bar hopper to commuter rig, from touring bike to part time road rocket, and everything in between...the perfect all-rounder. Able to cover a vast amount of your cycling needs in one… Hard to argue with that

Compare to Vassago Fisticuff or VooDoo Nakisi or On One Inbred. Those cost Hundreds MORE.

The Frame is precision welded from specially shaped lightweight and strong aluminum tubing. The tubing is Gravity's own special XSeries tube-set. Look at the engineered, hydroformed top tube and bi-oval downtube. Designed for a responsive performance while maintaining a comfortable ride quality. Semi-compact geometry which allows for a more comfortable and upright position yet is still aero-enough for some serious road efforts.

Compare this bike to the Trek, Giant, Specialized bikes that sell for $1,000 plus tax.
Most have straight blade forks and aluminum frames, many have semi-compact frames. Many other bikes have only 16 gears, the Gravity has a much wider range with 27 gears. Trek, Giant and Specialized road bikes with similar specs sell for $1,100 range.

Why pay almost twice as much more money for lesser equipment?

The Gravity Zilla is only $599
The Factory Direct price includes shipping by UPS ground to 48 states.
