When you say "kits", you bought the engine from WhizzerPaul (Whizzercruiserparts.com and all the other correct components)? and put the parts on your own frame ??? The kits available now don't have the Whizzer logo on them. I am a bit confused as your bike looks like a very good condition NE5 of some year.
100% Cruzzer M/B, many were sold with the Whizzer Logo
Whizzer USA threatened to sue, But Cruzzer got away with it anyways calling the bike and parts Reproduction
Cruzzer stickers were also put over the Whizzer Logos sometimes
To the best of my knowledge
15 year contract with Taiwan 1999-2009 bikes, parts contract until 2014
2014 Whizzer USA Contract with Taiwan was over Taiwan released the Cruzzer in USA for sale
Cruzzer was first sold as a kit,
Kit included Motor & Bike $1,999
Cruzzer sold the bikes calling them 148cc 4 hp and said top speed of 45 mph
The disclaimer that it should be operated on private land allowed the complete bike to be sold in USA
The disclamer also said Cruzzer M/B is not affiliated with and does not represent Whizzer M/B
All parts are Reproduction
