I learned that Adam Opel, the founder in 1863 of German automobile company Opel, had a grandson called Fritz Von Opel quite obsessed with rocket propulsion. Since he was always looking for ways to get publicity for the Opel brand (he was the company testing director), he got the idea to build a machine to beat the world land speed record. Sound familiar marketing approach to you?
The motorcycle was equipped with a 500cc single engine able to reach 75 mph, then when reaching this speed you could lit the side placed rockets via a foot pedal to boost the bike to an engineer calculated speed of 130 mph.
The Opel Motoclub 500 was exhibited at the 1928 Berlin Motorrad Show but apparently the German government forbid the landspeed record tentative because considered too dangerous. It seems that a few models (without rockets) of the Opel MotoClub 500 are still in existence and you will agree with me that 80 years later it’s still a Best Of Show.
