12 speed Cube Hybrid Bosch CX performance pedal assist bike

Hi I'm selling my Cube 12 speed Bosch pedal assist bike , I've got the original Bosch charged and nothing has been changed on the bike since I seen it and bought it brand new. This bike has the Bosch 625wall tube battery in the down tube of the frame and goes almost 50kms on factory motor but you can buy different tuners for it that do different things to make the motor perform better. This bike was bought this spring for $5300 and i will not accept anything less then $2000 cash would prefer closer to $3000 because this bike is in mint condition and the battery lasts for about 8 hours of continuous riding and it charges from almost dead tov3 full bars in about 1.5 hours. Please serious inquiries ONLY and I will want proof of you having the money to buy it and no offer less then $2000 will be accepted
