Using trainer as dynamo

Asked by: Jen Sheppard

What is the most efficient dynamo?

One of the most powerful dynamo hubs currently on the market is the Shimano UR700. At 25 kph, it can produce a peak output of around 5.5 watts to a USB charger. To compare, the SON28 only puts out about 4.5 watts at that same speed.

How much electricity does a bicycle dynamo produce?

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

Can you put any bike on a trainer?

Most direct drive trainers are compatible with mountain bikes, as long as you have the correct adapters for your bike and a cassette that is compatible with the drivetrain on your bike. Here are tips for setting up your mountain bike on a direct drive trainer: You will need an extra cassette.

Does bicycle dynamo produce electricity?

The dynamo has a wheel that touches the back tyre. As the bicycle moves, the wheel turns a magnet inside a coil. This induces enough electricity to run the bicycle’s lights. The faster the bicycle moves, the greater the induced voltage – and the brighter the lights.

What RPM is needed for electricity?

1,000-1,800 rpm

1,000-1,800 rpm is the rotational speed required by most generators to produce electricity. The high-speed shaft drives the generator which produces AC electrical current.

Can you power your house with a bicycle?

Nope. Not even close. Pedaling a bike at a reasonable pace generates about 100 watts of power. That’s the same energy-per-time used by a 100-watt lightbulb.

Does a bike trainer damage your bike?

While the “riding on a trainer will damage your carbon frame” myth has been officially busted, indoor riding can still pose a threat to your bike in two ways: wheel strain and sweat corrosion.

Is riding on a trainer harder than the road?

“Most schools of thought say your an outdoor workout should be 25 to 35 percent longer than a comparable indoor one,” says triathlon coach Robert Pennino, founder of Terrier Tri and T2 NYC. “So an hour on the trainer would be roughly equivalent to an hour and 15 minutes on the open road.”

Is it safe to use carbon bike on trainer?

Based on current manufacturer warranties, though, it is clear those challenges have been overcome and carbon frames are safe to ride on indoor trainers, provided out of the saddle efforts utilize the proper “up-down” technique.

Can I use DC motor as dynamo?

Essentially any electric DC motor with a permanent magnet can become a dynamo. Rather than applying current to the motor to cause it to spin, you can turn the shaft of the motor and generate a current.

How fast does an alternator have to spin to produce electricity?

Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM. Typically, alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.

How much electricity can a 12v DC motor generate?

12v DC motor with maximum 1.5A capacity can generate 18W of power. 12v DC motor with maximum 3A capacity can generate 36W of power.

How much power can a bicycle generator produce?

A typical bike generator can produce 100 watts.



If you pedal for an hour a day, 30 days a month, that’s (30 x 100=) 3000 watt-hours, or 3 kWh. That’s less than 1% of what a typical family uses in a month (920 kWH). You generated 0.3% of your energy, and continue to get 99.7% from the grid. Good job.

Can a bicycle dynamo charge a battery?

The dynamo will charge the battery as long as its voltage is higher than the battery’s voltage. You are correct, as your battery approaches a full charge, it will be around 14 volts and the dynamo is rated at 12 volts, so it will not be charging in this situation if it is actually 12 volts.

How much voltage can a dynamo produce?

Related to that, a typical bicycle dynamo generates 6V and 3W of alternating current. Sure wouldn’t power a 100W lightbulb, but it still can charge phones and power some decent LED flashlights, although not both at the same time.

How many volts does a bicycle generator put out?

Technical Details

Is a bicycle dynamo AC or DC?

A standard dynamo creates a direct current (DC) – a one-directional flow of electrical charge. A bicycle dynamo creates an alternating current (AC), which reverses direction occasionally.

How do I turn an exercise bike into a generator?

Quote from video: I have a 25 watt 125 volt bulb in there let's see if it light it. Up. 60 watt bulb.
