Ambition helps motivate us. It helps us strive for more and reach new goals. The X Ambition is built for more. More miles, more adventures, more smiles! You may know the Poseidon X and the X Ambition is the more improved version. We focused on improved comfort with a more upright riding position and a new saddle design. We increased braking power by adding the same brakes as the Redwood and completed the build with 700 x 40 Kenda Happy Medium tires for good speed on the road and grip on gravel. X Ambition vs Redwood Comparison Difference between the standard X and the X Ambition: We get this question every so often so we figured we'd explain a little further. The X Ambition offers a more upright seated position which is more comfortable and upright (see image below). The X Ambition offers stronger brakes like our Redwood model. We offer a newer comfort forward saddle which may work better for more riders across the board. The X Ambition also comes with 700 x 40 tires which gives the ride a little more of a plush ride feel but the tread pattern allows this bike to accel on dirt and pavement.
