It’s hard, my club the wizards has been around 10 years now and we had 6 solid members that I love to death Like brothers, and a new prospect.
Having a spare bike for pals to ride will certainly help. When you get 3 pals who all have bikes make weekly meetups a thing. Keep your group strong, even if you don’t ride every single week, hang out, drink beer eat pizza. Wrench on stuff together. It’s crazy man, mopeds are awesome but hanging with my moped friends is at least half why I still love them after all this time.
