You know, I just tried to count all the subforums on BF and stopped at 30 and there was plenty more to go! Some overlap would be inevitable, and I haven't seen that become this much of a problem until now. That e-bike topics would surface in the 'Fifty Plus (50+) subforum should not surprise (or annoy) anyone. Where the eff else? The main Electric Bike forum is for the nuts and bolts of electric bikes but it isn't hard to see that people over 50 have been among the early adopters and would want to talk about issues beyond "what brand of e-bike should I buy?". I'm sure I've seen upset posters advised to leave certain threads if they find them offensive.
