There really isn't much to service on the Nexride bike seat. If you have a question about adjustment or need a part, shoot us an email.
Installing a Seat Bag
Most seat bags can be attached to a Nexride saddle, but this may require a bit of ingenuity. There are at least two good ways to do this. First, if your saddle is far enough aft (usually the case with tall riders), then you simply thread the seat-bag strap through the rails as with a conventional saddle. This is shown in the left photo below. Alternatively, you can thread a sturdy tie wrap ("zip tie") through the openings toward the rear of the saddle pivot block and then through the opening at the top of the seat bag through which the bag strap normally passes. This is shown in the right photo below. (Of course, you'll clip the tie wrap; the tail is left on in the photo to more clearly show where to thread it.)
