Gravity Real Customer Reviews

A. J. "..love this bike and it rides real well… original shifters worked well and the drops were nice...around 500 miles on this bike and it (rode) pretty good for the money. Why spend thousands...

T. S. "...most of the (wide tire road) options...available from the big manufacturers were beyond what I wanted to spend….so I turned to the internets(!) and discovered bikesdirect.com.…came about 90% ready...put the front wheel and handlebars on, I had to air up the tires, put the pedals on, and adjust some things (brakes, seat, shifters, derailers). But bikes are easy...I was up and riding within 30 minutes….

Since this bike is so well rounded, I can run errands with it during the week, commute to work on it, and take off some unnecessary bits for a long ride on the weekend. It’s almost like fitness disguised as fun..."

P.H. "...The (other brand) CX bike is probably the cheapest fat-tire road bike, and it was still $250 MORE than the Gravity..…$800 would get me a (other brand) Tourer with Sora 10spd, but that bike weighs close to 30lbs."
