Does anyone know if this could be used as a bicycle generator? At what RPM does the alternator start to output voltage/current?

I would say pretty high rpm. It doesn't put out full until about 1200rpms. Starts at around 900 before anything reads on my amp meter.

This alternator is usually used on a garden tractor that would idle at about 800 rpm which is the minimum you would have to achieve. Also, it is AC voltage and needs to go through a rectifier to produce DC. I think it is a poor choice for a bicycle.

It might be a little heavy for a bike. Not sure of the weight as I put it on a skid steer and weight was not an issue. Most alternators perform best at 5000 RPM or higher, but have enough output at 1000 RPM to start charging a car battery.

The amps drop from like 10 to 2.5!it's still going to be 1 1/2 hp,only at a slower speed (less gpm).80% of the time low speed is good.once in a while run it on high to mix water...shock,ect....

Yes of course, that is exactly what the 12v output is for. However, it is only 4 amps so it would take a while. Also, it has no smart limit or anything so it will be able to overcharge the battery bank.I would recommend using a standard 120v AC charger plugged into the normal AC outlet of the generator. It will charge faster and safer.That said, the answer is yes.

hey Icepuck, did this work? Could you do same with a battery charger I am wondering? Im trying to run 12v lights off a generator and trying to find a solution... FF here too and rigging out a response trailer..

HI, This alternator is 160 amp ,if you don't have the demand you won't see the amperage, also this is bigger than the original alternator , some year/models needs modification like grinding the bracket/mounting of the alternator make sure you know before purchasing also make sure you have Good Highest core cranking heavy duty New battery and run 4 gauge wire too

I would say no,,it says "*Safe for Alternator Outputs up to 120 Amps". My van is a 100 amp alt.

its a 600w alternated generator... it will never reach 600wats... probably closer to 450w... though you are right there isnt any data supporting this... just do some research about ac to dc conversion...

This is a 12V battery, but for running even a small winch that still pulls ~40 amps I'd go for a bigger battery. This one is rated for 18 amp-hour (hinting it'll supply 18 amps for 1 hour, or 9 amps for 2 hours, etc) and I don't think it's a good idea to pull more than that 18 amp rating for more than a few seconds (like to crank a car).

A long time- This is a nice little unit but needs to turn nearly 1,500 rpm to make enough juice to really get to work on a 12 volt battery. It depends on the size of the battery and how discharged it is. If you had an average car battery mostly discharged and were running this on a bicycle set up it would take hours- I'd guess at least 4 to make any headway. I hope you have good legs. Mine makes 5.5 volts at 700 rpm.

I start to see some current at around 10 to 12 mph. It will depend on what voltage you need. I use it on a 24 volt system.

Starts mine just fine. Just check the specs on your AC and the generator. You can also add a hard start capacitor to assist the generator with the load of starting. I believe the Yamaha is 16.7 amps constant and 20 peak. Check your manual on the AC for it's specs. You could however hook it to a 20 amp home outlet and see if starts off of that. If it does the Yamaha should start it but keep in mind this is not a gaurantee. My 13.5k starts off of all my 15 amp garage outlets.

I really don't know. Mine always starts quickly and I've never had any problems with it. I would suggest calling up the manufacturer of the generator.

Hello, The EZ Cycle Motorize Exercise Bike is 120 Volts. Please let me know if you have any additional questions. Warmest Regards, Dorsey Dollar ActiveForever

Just as a car can't go from 0-60mph in a few seconds without a huge engine, anything with an electric motor has a "surge draw" to start the motor accelerating it up to speed in a couple seconds (including fridges, pumps, etc). That surge demands 3-4 times the normal power. I've tried plugging in a small AC fridge (that measures ~18 inches in all 3 dims with only 1 amp AC draw normally or 120 watts) into an inverter. It was a 400 watt inverter with 800 watt surge rating, yet it would go into the overload alarm instantly not even starting. I'd expect any pump to need more power than that and this units inverter according to the manual says "450 watt continuous, 600 watt for under 5 minutes and 900 watts max surge". So based on my trying a similar inverter on a small motor, I'd bet under a 5% chance this would work for you. I've even been reluctant to try running a typical fridge off of a 1200 watt generator because of that surge demand. Also, if going off of just this units battery which is under 30amp/hour, if you could run something like that it's battery will be drained in 20 minutes. So this is a real short term power source for such loads and won't keep your place from flooding all night or such.

It depends on what kind of load you put on your bike generator. If you are trying to charge a cell phone it will only be about 2 Watts of power and you will barely feel it. If you are trying to charge a small 12V powerpack you will more resistance. So it is all realted to what you have the bike generator hooked up to. Brad - Electrical Engineer Pedalpower Generators LLC

Hello Connie, For this application it is a little to small you will not be able to rev your generator well and you will find it slightley under powered. I would recommend a larger regulator. it works fine on my 6500 Watt but I normally do not use it at full capacity.

Really should have hit the "I don't know" button. I would assume that functionality would be dependent on what other demands are made on the generator at the same time. Asking a Generac engineer might be a better course of action. You may encounter situations similar to folks who vacation in RVs deal with where you need to turn off certain things to allow for running others. Hope I've helped
