Bike Riding in Busan

I saw a thread about this posted a bit back but I thought it was time for a new one. Anyway, anyone interested in riding bicycles on the weekend? I have a road bike and am sick of riding the same roads alone. Ideally, I'm wondering if there is anything like a foreigner bike community in Busan but really, more than anything, if you just want to go for a bike ride on a Saturday or Sunday (during the day), post on this thread or private message me. Thanks.
