More difficult to find. Currently, generators and their headlights are less common than battery lights in American bike shops. It’s often necessary to purchase them online.  Harris Cyclery carries a wide selection, though:
'''Schwieriger zu finden!''' Inzwischen sind Dynamos und zugehörige Lampen weniger verbreitet als Batterielichter. Durch die Änderungen des StVO 2016 sind Batterielichter unter bestimmten Voraussetzungen ebenfalls an Fahrrädern erlaubt. Daher muss man öfter zur Online-Bestellung greifen

'''Schwieriger zu montieren!'''. Seitenläuferdynamos und Rollendynamos (siehe unten) müssen ordentlich am Reifen ausgerichtet sein, um den Widerstand zu minimieren. Einen Nabendynamo muss man in ein Laufrad einspeichen. Lampen müssen festgeschraubt werden und die Verdrahtung sollte fachgerecht ausgeführt werden. Einige Geräte haben Schwierigkeiten mit [[Carbon]]gabeln. Im allgemeinen kann man sagen, dass man ein wenig Mechaniker- und ein wenig Elektrikerfahigkeiten haben sollte. Wenn ein System allerdings einmal ordentlich installiert ist, gibt es wenige Probleme.


More difficult to install.  Bottle and roller generators (see below) must be properly aligned with the tire to minimize drag.  A hub generator requires that someone build it into a wheel. Headlamps must be bolted in place.  Wiring must be properly installed. Many units may present difficulty with carbon fiber forks. In general, some mechanical skill and a bit of electrical skill are needed, although once a system is properly installed, few problems are experienced.


Drag.  This problem is minor, and frequently overstated.  Chris Juden, technical editor for the Cyclists Touring Club of Britain, has noted that modern generators impose drag equivalent to climbing less than 20 feet in a mile, and the best impose less than six feet per mile.  Still, some may feel this is important. (One inadvertent test - a generator that accidentally bumped on during a tour - proved to me that the drag barely reduced my flat-ground speed, from 20 mph to 19 mph.)

Cost. A modern generator system costs typically twice as much as a battery system with comparable output.
