History of JAP after the name of founder John Alfred Prestwich goes back at the start of 19th century when John started to produce his own internal combustion engines although the company was founded in 1895.
He designed the first engine in 1901 but it took him two years to bring that engine into production.It was 600cc engine that had three cylinders. 1923 he patented desmodromic valve design.
First JAP motorcycle had BSA frame with an output of 3.5 hp.
Pavel Malenik is another genius who has constructed the North London Garage’s Replica of JAP Motorcycle.He is mostly interested in unusual motorcycle constructions from the beginning of the motorcycle industry with a focus on those ancient engines.
He aims to create every part manually himself the same way it was done back in the day with as little as possible usage of mass-produced parts. All my motorcycles are fully functional, not just for showcase.
1.How did you started building motorcycles?
Pavel : I started during socialism in the Czech Republic before 1989 when the number of obtainable motorcycles was very limited. Every motorcycle enthusiast was trying to differentiate from others and I was no exception.
2.North London Garage replica is a pure art.What was your motivation in building it?
Pavel : NLG is my attempt to resurrect the forgotten past of this interesting motorcycle in the first place. I built this motorcycle to experience the feeling and riding such a beast 110 years after it was originally created.
Also, I like to let the public see how interesting motorcycle history was, hear the engine roar…
3.What you would like to call yourself Innovator, Designer or Builder?
Pavel : As stated before, I am mostly interested in historical motorcycles of interesting construction, which was created only as prototypes and disappear during the time.
I am trying to research as much information as possible and build motorcycles as faithfully as possible. Mostly I and up with a few old photos which I use as a base to build it. So I call myself an engineer and builder.
4.Could you please let me know how the North London Garage replica was build?
Pavel : There was one photo on the beginning which caught my eye. Since it was a motorcycle with the biggest engine and power which ever used belt transmission. It took about a year to prepare documentation, draw blueprints, design engine etc.
Then I started with the construction of the engine and continuously build the whole motorcycle over the next two years. Every piece is hand made in my home workshop with the exception of tires, saddle and spark plugs. The first test ride was done on Monthlery circuit (France) which is only one fitting the motorcycle speed and limited maneuverability I was able to get on. The entire construction of motorcycle is mentioned here (The Old Motor).
5.How do you see yourself 5 years down the line?
Pavel : At the moment I am working on a new project, V8 motorcycle also based on JAP historical work. After that, I will see what will catch my attention next..
6.Any plan to build electric custom as it is a trend?
Pavel : I am not interested in electric motorcycles at all. In my opinion, the beauty of motorcycles lies in the combustion piston engine.
