I just purchased the Gravity FX1 & let me tell u, this bike is awesome. I took it out just on regular back mountain roads but this bike shifted great even under pressure going up. I had 2 do some fine tuning 2 the front & rear gear units.the brakes stop on a dime, I ddefinitively would say this bike will hold up 2 a much more expensive bike. After you adjust the front & mid shock this bikes smooth.so dont waste your money on $200.00 bikes at department stores, if you have the extra cash spend it. You will not regret it.
