Yes.

Yes.

Nice. Enjoy.

The two fire extinguishers next to it aren't a good sign. Plus the chain's slack

I'm sure my wife thinks that our tandem has a motor
That looks a nice bit of kit though

 

[Pat "5mph"]

I like that!
Imagine touring on hilly terrain, one motor, 2 pair of legs ....

Cool.

It's a Cycle Master rear wheel. I had one in an old Rudge when I was 11 and used to wazz around the block on it. I later had a BSA Winged Wheel which was much the same thing. 32cc if I remember correctly.
