What you say is true, to a point. Some airplanes were once made of wood. Many bicycles are made of metal. Both true.
Some bicycles are made of steel; some are aluminum; some chromoly; some titanium; some are alloys of a few of the preceding; etc.
They were careful about picking the wood for aircraft even in the good old days. Birch and ash were used a lot. The plywood was constructed of painstakingly fine, multiple layers of veneer. They used woods that could take a lot of punishment. Not something you'd build a garden bench out of.
I'd need to know what kind of wood(s) that bike was made of and how it was made before I'd consider a motor. But, hey, if it was done right...
