I can't be the only one who can't stop laughing when hearing that name.
Only to simplify the article and definitely not for any other reasons at all I will use the term Cock instead of the complicated and long word Cockmobil. But please keep in mind that Cock is not the official name of the vehicle.
What is a Cock?
The Cock is a vehicle that was made by the Cockerell Fahrzeugwerke AG in Nuremberg around 1924. It had three wheels and was available in two versions, as a roadster or a van.
What are the advantages of having a Cock?
The Cock couldn't only be driven legally without a license, it also was very compact which allowed you to fit it into tight spaces or holes. It also was very cheap to get and to run, only needing 3.25 liters of special juice per 100 kilometers.
Does one have to be careful when riding a Cock?
Yes, with its small size and only partly closed body, the Cock isn't exactly safe for its driver, I would recommend wearing protection when riding the Cock. However, you also have to care about the other road users, since the normal convertible version has a very sharp rear end with which the Cock could drill itself into the car behind you if you brake very suddenly.
Are there any other disadvantages?
The top speed isn't exactly mind boggling, according to the brochure you can ride the Cock at a speed of "50 km", I presume they mean 50 km/h or 30 mph. If you wanted the roadster, you had to pay extra money for a windshield, if you ordered the van you got a windshield for free but no inscription on the delivery box thingy, you probably had to organize some expert on your own if you wanted something written on your Cock.
Want to ride your own Cock?
This will unfortunately be difficult since only 5 units were made around 1924, and I was unable to find information about any of them, my guess is that all of the Cocks have been crushed. Because of this lack of information, it's also impossible to penetrate deeper into the matter about the Cock, which sadly means that after a disappointingly short time the Cock has been fully dealt with.
