The 14"x2.125" (57-254) knobby tire for electric bikes makes a nice aftermarket replacement for the standard factory tires that came with a new e-bike. Your ride is only as good as your tires, and we recommend this superb tire with its knobby tread, a design that is as good on the soft ground as it is on the hard concrete. This is a traditional pneumatic tire and it requires an inner tube.
