Fruin’s bicycle shop was my local stop for bikes when I was a child. We would always drool over his home made motorbikes on display in the shop window. I had to settle for a Bantam!

I keep seeing “reports” that there was “only one built” and only two ever built” etc which is strange as I built two ! The first was sold to Geoff Monty ( Monty & Ward ) and the other is being rebuilt in my workshop when I`m not building Vendetta frames for other people. The original Fruin 4 used Moto Demm cylinders/heads/pistons and rods and was married to an Albion box. The frame was one of Bert`s own. He used very small fillets of bronze which worried me at the time ! Bert was a lovely bloke. I bought two sets of castings and remember how awful Bert`s drawings were !! I used N.S.U.Quickly components but wasn`t keen on the angle of the carbs and exhaust and have ben trying to find N.S.U. “QUICK 50″ components without luck. (anyone got any ?) My original used Reynolds l/link forks a Honda Cb92 front wheel and a cotton Telstar rear with my frame. I used two Lucas contact breakers, one each side of the crank.

The cylinder barrels are definately nsu quickly. The bike is part of a collection which also includes the double overhead cam 125 single Fruin. This collection can be viewed by arrangement.

The cylinder barrels I believe are Moto Demme and not nsu.

I dont know who paul is, but I do know that this bike is owned by a friend of mine in north lancashire, the bike was bought straight from the museam on the Isle of Man as a present by my friend’s wife and was never the property of a ‘Paul’.

The bike is stunning, and sounds even better than it looks.

This bike is the original with the 4 NSU Quickly barrels linked to Fruin’s crank, and the only 1 in exsistence.
