There should by some more inspiration and motivation generated by the club.
I've suggested the Member of the Month idea used in other clubs earlier, which hopefully will be underway soon , to help with it.
I'm sure there's plenty of other ideas to get get people inspired to try something new; nothing works best than some friendly competition (1/4 times and members rides etc..). As long as members are motivated to try new stuff or even take different routes of the existing modifications, the club will be healthy in my opinion.
