Basis for an old school Bobber

Moin my name is Daniel, I am 25 years old and I want to start my first conversion after a long time of thinking. Since I want to learn the screwing anyway, I want to do everything myself only if we need to be welded etc. I let the professional do it. I have been a sportsman for a long time, I am an absolute newcomer around the area of the Chopper/Cruiser. I am looking for a good and above all cheap basis for a Bobber. It is important to me that I have spoke rims, not who I think it’s also easier if the year of construction is before 19889. I thought about the usual Japanese manufacturers. Above all, they should not only look good but also drive themselves reasonably. Visually, it should be classic, without snobbs, the new Triumph Bonneville Bobber is optically quite exactly the direction I want. Is just not a motorcycle what you can get ready to buy. . Which models can you recommend to me? Thanks for all suggestions
