Being visible is paramount to staying safe while riding and there are many different types of lights available to help with that pursuit. But, the king of them all is the Dynamo light. Dynamo lights use a bicycle mounted generator for power, staying lit while riding at night and low visibility times of the day. Read on to learn how Dynamo systems work and why they are so dependable.

Dynamo Light: Where Does The Power Come From

With no battery, you generate power with your motion. For a Dynamo light to work you need to attach a generator to your bicycle. Generators are rated for either 3.0 watts to power both a headlight and taillight, or 2.4 watts to power just a headlight.

Generator types

The two main generator types are hub type and bottle type. The hub type is built into a front wheel and generates power as the front wheel spins. Bottle type generators mount onto a bikes frame or fork. Bottle generators have a small wheel that rests against the tire and generates electricity as the tire spins the wheel. Typically, the hub type generators have lower resistance than the bottle type and won’t wear out a tire as quickly. Bottle type generators are typically less expensive and can also be installed on your bike without rebuilding or replacing the front wheel. Another benefit of bottle type generators is that they can be disengaged during daylight hours so you can ride resistance free. That being said, as hub generators become more efficient and less expensive, the bottle generators are becoming less common.

Front Light types

Of all the light types on the market, high output LED headlights rule the roost. These HLED lights use very little power to deliver a ton of light. While we are talking about light, most headlight’s power are measured in LUX. The differences in power can be seen below. In addition to light while riding, most headlights have a capacitor to store power and allow the light to shine for a small period while the bike is stopped.

Rear light types

Rear lights use LEDs and blink while you ride. They can be mounted to the bicycle’s chainstay, seat post, or fender. These rear lights are typically wired from the front light, across the bike, and to the rear light. While it’s easy to run wiring through a bike built to accommodate them, it is difficult to cleanly run wiring on bikes not made for them.

Benefits

Lighting in general is one of the most important aspects of safety on the bike. While you don’t need a dynamo lighting system to be safe, they do offer some advantages over battery powered lights. First benefit is you can jump on your bike and go because you never need to charge a dynamo light like you do a battery system. Also, dynamo systems can be upgraded to charge products via a USB port. Finally, Dynamo lighting systems enjoy the feature of being extremely durable.

My transition into winter has been cushioned by fine products from Sealskinz, most notably the Halo Overshoe. Read on to learn about my first impression

First Impressions of Sealskinz’ Super-visible Halo Overshoe

by John Brown, HaveFunBiking.com

The pond in my back yard is frozen, all the leaves have fallen off the trees and the snow blower is ready. These are all signs that Minnesota is firmly in the act of becoming the ice planet Hoth, as history suggests. Happily, my transition into winter has been cushioned. I have some fine products to test, most notably the Halo Glove and Halo Overshoe, from Sealskinz. While I have written about the Halo Glove, learn about my first impression of their Overshoe for winter biking.

Out of the box, the Halo Overshoe

Sealskinz has made every effort to keep their products as waterproof as possible, including the packaging. The Overshoes came to me on a cardboard backer and was held in place with paper bands. In short, the Halo’s Overshoe construction is as impressive as its packaging. All the seams are in the product are welded (so no stitching). Plus, tape is bonded to the backside of all the seams to ensure they stay waterproof. The closure uses a zipper with large teeth so they operate under pressure. Then at the top of the zipper a large rubberized Velcro strap keeps everything tight. Also, the toe and heel are reinforced with a Kevlar fabric for durability. Finally, the most unique feature of the Halo Overshoe is its LED light mounted in the heel for visibility up to 500m away.

Packaging for the Halo Overshoe is neat and ensures the bootie stays waterproof.

First fit impressions

Trying the overshoes, my first time was a bit of a challenge. They fit snug and I had issues getting them to zip up due to where my shoes buckle was located. However, I am happy to say that was a onetime experience. I am not sure if the overshoes stretched, or what since that first time? Now, the overshoes fit on with ease and the zipper hasn’t offered any resistance. The fit is great as they are snug without being too tight. Not like many overshoes for bikes that often suffer from the toes flipping up due to a bad fit. While the Halo Overshoe stays put perfectly.

Waterproof material, high visibility LED, and bulletproof construction are hallmarks of the Halo Overshoe

Overshoe Warmth

So far, I have ridden with the Halo Overshoe in conditions ranging from 30’s and raining down to windy at 11 degrees. Through all that weather I can happily say the Halo Overshoe has kept my feet warm and toasty. Even with the large holes in the bottom of the overshoe for the heel lugs and cleat, all the other waterproofing features kept my feet dry.

Added Visibility

The great thing about the overshoes LEDs is that, while blinking they are also moving up and down as you pedal. This gives them a unique appearance that is virtually impossible for drivers to miss. On top of the LEDs active visibility the Halo’s also have reflective material applied on the side, cuff and along the zipper. The red LED lights are also easy to activated by pressing on them.

Continuing tests

As the weather continues to get colder, I plan to see just how low a temperature I can go with the Halo Overshoes. As I mentioned above, so far I have had good success down to 11 degrees with wool cycling socks, standard cycling shoes, and the Overshoe. Moving forward, I plan to use the Halo Overshoes in combination with Sealskinz Superlight sock to see if I can be comfortable into single digits, Stay tuned for more info.

Sealskinz' has evolved their product line to include the Halo Bike Glove.See what makes these gloves interesting for winter rides.

In a previous article, I talked at length about the Sealskinz’ new Super Light Pro Sock. While Sealskinz as a company began with socks, they have evolved their product line to include headwear and gloves for winter rides. One of the products that piqued my interest was the Halo glove. It drew my attention because it is a waterproof, winter glove with an active blinker system built in. Read on to see what makes these gloves interesting and some of my initial thoughts.

The Halo Glove for winter rides

Even though Sealskinz made a name for themselves with socks, they didn’t allow themselves to get caught on their heels (HEELS! Get it!). Sealskinz is committed to keeping all your extremities warm and dry. That mission is the inspiration behind the Sealskinz gloves we will be reviewing for winter rides. My first review will be on the Halo glove, a unique waterproof glove with powerful LED lights built into the back of the hand.

Halo Glove

Waterproof doesn’t stop at the product for Sealskinz. Even the packaging that holds your glove is considered. Rather than punching holes in the glove to mount it to a backer card like most brands, Sealskinz sews loops into the glove to ensure it never gets damaged.

The Halo bike glove is an $80 investment full of many features. It is constructed with a synthetic suede palm, incorporating gel pads for greater comfort on winter rides. The outer shell is completely waterproof, and the glove is machine washable. Additionally, the liner uses an anti-slip material that won’t pull out of the glove when you remove them. Finally, the cuff closes with soft Velcro straps that are large enough to be manipulated with a gloved hand.

Bicycling Glove Features

One thing that is unique to cycling gloves is the way they insulate. Most cycling gloves are windproof, waterproof, and have minimal insulation. I can hear you asking already “minimal insulation?”, yes minimal. Cycling gloves rely on you to generate heat by exercising on winter rides. Under those circumstances, the glove holds the heat you create, keeping you warm. By being water/windproof and relatively thin, cycling gloves offer better dexterity than a normal winter glove.

First Impressions

Immediately upon putting the gloves on, I was impressed. The liner is soft and warm to the touch, and the glove fit was great. All the fingers articulate well without any pulling of material folding uncomfortably. Additionally, the lights activate easily and are really bright.

 

The first time I rode with the Halo bike glove the temperature was just below freezing and rainy. Luckly, it wasn’t a real downpour and more of just a misting, but it was wet none the less. My forty minute commute ended with all my fingers being warm and toasty. Since that day I have ridden down to about 20 degrees and the gloves never left me wanting in the warmth department. My commuter bike has a flat handlebar, so when the Halo’s lights are activated, they shine forward giving me more visibility to oncoming traffic. In the case of a drop handlebar, the Halo glove will shine to your sides.

The Halo’s lights are really bright, and really lightweight.

Moving Forward

I hope to push these gloves as far into the cold as I can handle. Once I reach the Halo’s limits, I get to switch to Sealskinz Highland Claw Glove for the colder temps. Overall, I am really excited to see what the life of the lights on the Halo glove is and if they can survive the cold and moisture of Minnesota’s winter. Stay tuned for more info.
