Automatic Shifting Bicycles by Nirve

Automatic shifting bicycles are perfect for anyone who wants a bike that has more than one gear, but does not want to have to shift gears on their own, or wonder if they are in the correct gearing while riding a bike. The Nirve Ultraliner automatic shifting bike features Shimano's newest auto transmission. The Nexus automatic hub works great on hills and flats. The really nice feature is that you can fine-tune the shifting, so that if you want it to shift a little sooner, or later, simply turn a dial and the internal hub is now adjusted to your riding comfort. The Nirve Ultraliners are also equipped withe a Shimano Dynamo hub in the front that generators enough power to incorporate a generator light if you would like to add one.
