Acceleration 0-45 km/h

Hi guys, a workmate has a 50cc scooter (Speedfight), which is throttled to 45km/h (continuous transmission). Since he always jokes about my mountain bike (Cannondale Carbon 2 in 26 inch year 2013, incl. pedals 9,25kg standard, i.e. with Racing Ralph), I ripped open the flap big, that I am faster than his scooter (up to v max 45km/h). Can I get that? The scooter will take between 7,2 and 8,8 seconds. Is that even possible for the biker? I pl To start in the 14th aisle, then to look at No. 18 and then the 20th and highest aisle. Would I be happy about serious “attributions” … Everything takes place in the plain, on asphalt and at wind silence. Thank you.
