Buying this product appealed to me in the following 2 ways. First, I thought it would be nice to use my phone for the whole ride. Second, I cycle after work when my phone battery is already at low - these smart phone batteries run out very fast if you use anything that requires the screen to be on. So the battery would be dead 40-60 minutes into the ride if I used any of my cycle apps. On the other hand, I have never used a device such as spinpower. So basically I bought the spinpower device although I did not know what to expect.

It has been several weeks, and I am very happy with my spinpower. First of all, it really does make my phone battery last for the entire ride. So far, I have tried it on 2, 4, 6, and 8-hour rides with stops. I use my phone very actively. I run a cycle app, I recently used a gps feature to explore a new bike path, and I listen to books almost all the time. What a liberating experience not to think about turning the screen on and off. My phone's battery now last for the entire time. After an 8-hour ride, and some very active use, the phone battery went down maybe 4-5%, which was really great. Also, one surprising result - it takes me a fraction of the time to get ready to go out now because I do not have to spend time for charging the phone battery. In fact, I do not even worry about that anymore.

Overall, as I said in the title, I am very pleasantly surprised. I bought the device without much expectations, but got really good usage out of it. I highly recommend it to other cyclists, especially those going on bicycling tours.

I have been going on bicycle tours with my son over the last few years. We typically go 60-75 miles in one or two days, as he is 12 and we often have only a few days to do this between work and school. Our plan is to gradually build up our distance and capabilities, so that eventually we're going on cross-country and international tours. Back in 2010, I purchased a smartphone mostly for the advantages it would offer a bicycle tourist. The ability to use gps maps, determine weather, and find local hotels or bike shops can mean the difference between a miserable trip and a good one; it could also mean the difference between life and death in an extreme situation.

Problem is, I found myself on the road after dark with my phone out of power. I have used small portable solar chargers with built-in batteries, but they give an emergency charge at best and are more suited to the older style phone that use far less power (and will run for a week on a single charge). What I needed was the ability to charge my phone ANYWHERE at ANYTIME and keep it going all day long. The Bike2Power SpinPOWER S1 kit provides this at a cost that won't break the bank. First off, there are several issues that one needs to consider when using power from any kind of source that is off-grid. No matter if it is solar, dynamo, or backup battery, the watts and mah (milli-amp hours) need to add up. I'll focus on the dynohub since this is what I'm reviewing, but keep this in mind for ANY off-grid charging or power source and ask someone who knows if you don't.

The dynohub produces power just like other generators; it consists of a wire coil and magnets which spin from the bicycle wheel motion. As you might imagine, bicycle wheels spin at widely varying rates, which causes the power to fluctuate as well.

We cycle tour in Europe. 2010 we toured from Frankfurt Germany to Budapest, Hungary. We had a solar power charger but it was not powerful enough to charge our Garman GPS. We met a cyclist in Germany who had a similar device as the spin power S1 and said worked well for him.
We Purchased the spin power S1 for our next trip. I was not too hard to install and it was able to power our Garman NUVI 370 with no problem. It will also charges up our MP3 player. The cell phone mount also held our Garman NUVI with no extra modifications. We are happy with this purchase and recommend it highly.

I've only used this a couple of times so far to try it out before a long bike ride, but it seems to work great! It charges my phone ( I did have to buy a USB cord for my phone) like they claim. It doesn't really add any resistance, although a mo seasoned rider might notice some. It make a little noise, but nothing extreme.

Bought this for my FIL and once hooked up to his bike, it charged sporatically. It gave the "charging not supported" message on the phone and it did not charge, like many items still do even after receiving the message. Great concept, just couldn't get it to work correctly.

I have large oval forks and the mounting brackets are too small. The vendor drilled out the bracket holes but they still don't work! I'm going to have to design and make a mounting bracket this summer to be able to use it! Big bummer!
