Dutch Bike Spitz?

[Stewied176]

This one will really get your juices going
How old is this?
Where can I find more information about the make and model?
What do you think the value is?
It’s in v good condition, all working including the dynamo etc
I can’t find anything about this one and for the life of me I cannot find a serial number on it anywhere
Any help will be greatly appreciated thank you

All I could find was an ad from a business with the same name in a Dutch trade magazine from 1988. I have asked a question about this bicycle on the forum of the old bicycle club in the Netherlands and will report back if I get a reaction.

Thank you so much, this one is a real puzzle isn’t it? I found one reference to a MTB but zero info just an ad, I’ve emailed two bike shops in Amsterdam but had no reply. Someone somewhere must know Mince Pie and a Mulled Wine for the bust info

I got some replies on the old bicycle forum:

The patent appears to be applied for by Sparta, a large Dutch bicyle company. The patent was for a frame "of one piece", according to a frame builder who replied this didn't mean they didn't break...

Amazing thank you. I’m 100% further in now than I was this morning. I think I may contact Sparta direct now to confirm and request any other information. You’re a star ️

Interesting I thought that all patent numbers can be searched on a google patent search engine. I didn't know that.
