Ok well the Kink Kicker is well kiddish you can say since it has 18" TT although it does weigh 25.8 lbs. Then the Kink Curb with a 20" TT which should give an excellent feel to the bike. Which weighs 28.7 lbs. Even though it weighs more don't forgot it will give you a good feel and you can always change parts to better, lighter parts. I would get the Kink Curb because I think it's better than a bike with an 18" TT which could make it feel a bit to small. Both bikes have 3 piece cranks which is good. The only differences are the color, size on TT(top tube), sprocket ratio which are 9T-25T on the Kicker and 13T-36T on the curb which would both do good. I still suggest the Kink Kicker
