There are a couple of mountain biking groups in the greater Detroit area. Motor City Mountain Biking Association is one. They have meetups periodically throughout the year and is a great way to connect and network with other riders in your area. Another on the other side of the city from you is the Clinton River Area Mountain Biking Association which offer similar meetups.
My name is Derek with the Virtual Outfitting team at REI and if you would like to connect via Virtual Outfitting I would be happy to share more detailed information.
At REI, we believe time outside is fundamental to a life well lived.

x2 on Motor City MBA. Definitely not wanting to step on REI's toes, but you might google Michigan Mountain Biking Assn., they have local chapters around the state, Motor City being one.
