what type of device is a bicycle dynamo?
magnetos
alternatively, li-ion and lipo batteries have been becoming more popular with bicyclists due to their higher capacity and lighter weight compared with conventional batteries. more specifically, the 18650 battery, which has been popular with electric car manufacturers (for the same reasons) and are commonly found in laptops and flashlights.

dynamo systems require no batteries and may be permanently fitted to the bike.









































bicycle dynamos are actually magnetos and produce alternating current.

the gh6 version produced a rated output of 6 v, 0.33 a (2 w) from a 20-pole ring magnet with a stator having a continuous winding. original headlamp bulbs are 6 v, 0.25 a (1.5 w) (e.g., cry5) and a rear bulb of 6 v 0.04a (0.24w) (e.g., cry8). this is different from a modern standard bicycle dynamo, though replacements can still be obtained. common substitutions are the modern standard 2.4 w headlamp bulb and a tail lamp bulb of 0.6 w. one rider reports much more light with a 6.3 v, 0.25 a (1.6 w) type 40 bulb. led conversions are possible and will output a much brighter light than incandescent or halogen bulbs, though the led alternatives require the fitting of a voltage regulator and will strobe 10 times per wheel revolution if not fitted with a capacitor or rectifier to smooth the ac current output from the dynohub.
