Hi. My wife and I are really into fitness and looking for an alternative way to excercise. Since we both enjoy biking , I suggested that we look into a local mtb track that would be easily accessable to us. Although there is one probelm though.......we currently do not own mountain bikes, so I am currently in the market for two....preferable singlespeed. Can anyone suggest a good entry level bike? My budget would be up to $1,000 for both.
