Experience with Panasonic Dynamo hubs?

Asked by: Beth Jones

Are dynamo hubs worth it?

Dynamo hubs can save you time– Because you can charge your devices while you ride, you never have to sit around a power outlet waiting for your batteries to charge. This allows you to spend more time riding. For this reason, dynamo hubs are ideal for long-distance Randonneur riders and endurance racing.

Do dynamo hubs slow you down?

Do dynamo hubs slow you down? Dynamo hubs have a very small effect on your speed. But it is very small. It depends on what you’re using your dynamo to power too.

What is a hub dynamo and how does it work?

A dynamo hub produces electricity by passing powerful permanent magnets, usually embedded into the shell of the hub (the rotor), over a coil of wire (the stator). This process is called electromagnetic induction and is, in simple terms, the opposite of how an electric motor works.

Are dynamo hubs heavy?

P-Series dynamo hubs are ideally suited to wheel size from 646 to 716mm at 6V3W output. They are very light weight beginning from as low as 390g.

Do dynamo hubs make noise?

Re: Shimano 3N80 Dynamo Hub ‘Noise’



re the vibration; if any of the parts inside the hub (windings or magnets principally) are very slightly loose the hub will make a noise. It mightn’t last either. This isn’t the only reason for such a noise but it is high up on the hit list.

Can a dynamo hub charge a battery?

Your dynamo hub can charge lights, an external battery, a GPS unit or your smartphone during rides. Touring cyclists can charge USB devices on the road. In order to do this you need a front wheel with a dynamo hub and a charging device.

How much drag does a dynamo hub cause?

Most dynamo lights achieve their maximum brightness (and therefore drag) between 15 and 20KPH.

How do I choose a dynamo hub?

There are three different power specifications for dynamo hubs: 1.5-watts, 2.4-watts or 3-watts (all at 6-volts). Given that touring and bikepacking is often conducted at speeds below 25KPH/15MPH, the most powerful option (3W) is necessary for charging USB devices, and it’s the best for low-speed lighting too.

Are flashing lights on a bike legal?

Flashing lights are permitted but it is recommended that cyclists who are riding in areas without street lighting use a steady front lamp.”

How do you use a dynamo hub?

Quote from video: So when the wind moves forward a small current is produced. And this can be used to power your lights. And also to recharge devices such as phones gps's.

Is dynamo hub AC or DC?

AC

A hub dynamo is a small electrical generator built into the hub of a bicycle wheel that is usually used to power lights. Often the hub “dynamo” is not actually a dynamo, which creates DC, but a low-power magneto that creates AC.

How much voltage can a dynamo produce?

Start the engine and let it idle at not more than 1,000 rpm . Connect the positive lead of the volt meter to the D terminal and the negative lead to earth. The meter should read about 14 volts (or the 12 volt bulb should shine brightly). If so, the dynamo is working.

Which one is the correct disadvantage of dynamo?

Disadvantages: – Dynamos can store some energy, but in general, you need to move if you want to activate the light, if you stop, also the light. Also, a change in your velocity can imply a change in the intensity of the light, which also means that there is a minimum velocity needed to turn on the light.

How heavy is a dynamo hub?

SP dynamo’s hubs are not only the lightest, but also the most efficient 3w hub on the market, and are virtually identical to the BioLogic Joule 3. The lightest SP dynamo weighs in at an unprecedented 360-390g (lighter than the little Shimano S701 1.5w!) while attaining an unmatched efficiency of 72%.

How much power can a bicycle dynamo produce?

A cyclist’s average speed is 12 mph. Most dynamos are designed to produce ~3W (watts) of power at that speed.

Which dynamo is best?

Schmidt SON Dynamo Hubs (3W)



Schmidt is the industry standard for dynamo hubs in terms of both efficiency and reliability.

How much power does dynamo produce?

Most dynamos are designed to produce ~3W (watts) of power at that speed.

How heavy is a dynamo hub?

The lightest SP dynamo weighs in at an unprecedented 360-390g (lighter than the little Shimano S701 1.5w!) while attaining an unmatched efficiency of 72%.

Who owns Sturmey Archer?

Sturmey Archer was bought from the Derby Corporation (US owners of Raleigh) at the beginning of July for a reported £3m. The buyers Lenark Ltd.

Are Sturmey Archer hubs reliable?

The classic Sturmey-Archer AW hub is the most reliable gear-shifting mechanism ever made, and rarely needs anything more than a bit of medium-weight oil every so often.

Are Sturmey Archer hubs still made?

Arguably the greatest hub gear has to be the Sturmey Archer AW was made almost unchanged nearly sixty years and is still in production, in albeit much modified form.
