Peace, mercy, and blessings of God be upon you. I have a 29-inch mountain bike from the company 'Tune'; it's brand new, used about five or six times, and God knows it's like a new bike. It still has a year of warranty on the frame and about 5 months on the gears. The bike doesn't have any problems at all, at all, at all. Also, as a gift from me, a front light and a rear reflector. (Offers below 500 will not be considered). Please, if you call to offer less than 500, I will hang up. May God bless you. Only serious buyers should call.
