Add visibility in fall’s limited light for a memorable ride.

by John Brown

With school in session and Fall in full swing, using passively bright gear is a critical component to being better seen while riding our bikes. The two primary forms of visibility we need to focus on are passive and active visibility. Things like reflectors and bright colors are forms of passive visibility. In contrast, lights and blinkers are great examples of operational visibility. Read on to see where each one is helpful and most efficient.

Using visibility passively

Most autumn rides start in the light and only devolve into darkness as the ride stretches. Most riders rely on passive visibility to get them home in these cases. If your ride is under street lamps or lights, that passive visibility will get you home safely. The most common form of passive visibility is a lowly reflector. The CPSC requires these plastic devices installed on all bicycles sold in the United States. You will find glasses in white (front and wheels) and Red (rear).

Additionally, many apparel companies install reflective materials on their products. Like the reflector on your bike, these reflective materials will take any light thrown at you and return it to the source of the morning. Passive reflectivity falls short when there is no light source to activate visibility.

Sealing makes some excellent winter gloves that are both visible and insulated.

Using visibility Actively

When the area lacks a light source, you must create that light to keep yourself safe as a rider. For cyclists, Lights and blinkers are the most common devices for light. The light and the blinker differ because blinkers are designed to be seen, while lights allow a rider to see and be seen.

Great lights are usually rechargeable and use an LED bulb. These lights are necessary for riders who spend much time off-road or on unlit paths. While most mount onto the bars or helmet, a few companies integrate lights into the bike or your helmet.

What to use this Fall

Mount a pair of blinkers to the bike (one front and one back). Switch on the blinkers when riding in low light and high traffic. A front light makes things safer if your route will be unlit for any portion. Overall, think ahead before your next ride and pack to ensure you can see in the dark while others can see you.

Five Tips for a Memorable Fall Bike Ride

by Jess Leong, HaveFunBiking.com

Bike riding in the fall can come with many challenges and, at the same time, be very gratifying. For some, the bicycle season may be winding down. In contrast, many others wish to continue to explore the incredible autumn landscape on their favorite mode of transportation, the bike. Pedaling along the colorful autumn roads or trails is so breathtaking that I will admit that fall bike riding is one of my favorite times to ride. Not too hot, not too cold, and there are fewer insects once the first frost hits.

If you plan to ride and enjoy the colorful foliage this fall, check out these top tips before heading out.

Fall Bike Ride Tip 1: Layer It Up

For fall bike riding layering your clothing is key.

For fall bike riding, layering your clothing is critical.

The temperature fluctuation can be confusing when you want to get dressed and go biking. The thermometer in the morning can show temps like 47 or 48 degrees Fahrenheit. Then, by the afternoon, the temperature could be in the low to mid-70s! The best way to combat this is by wearing multiple layers you can easily remove and put back to find your comfort level of warmth. When layering, a good rule of thumb is whatever you decide to put on last will be the first thing you’d want to take off!

Pro Tip: Start while still slightly chilly. As you ride, you’ll warm up, and that chilliness will go away. However, bring an extra layer in case you stop along the way! You want to stay warm when you’re not riding.

Not sure what to do for layering? Check out our article about how to layer, why it’s beneficial, and what to wear.

Fall Bike Riding Tip 2: Beware of Wet Leaf Piles

The falling leaves are gorgeous, and leaf piles can be fun. However, a wet, crunchy leaf pile can be a hazard when riding your bike through it. Not only can water splash upwards onto your bike and legs, but the bike tires can slip on the leaves. When leaves are wet, they become slick or slippery. With a standard bike tire normally thinner, it has less coverage area for surface tension. A bike can slip out from under you if the leaves you are riding over slip away or get stuck in the tire.

Luckily, this is less of a problem if you have a fat bike or a mountain bike. The larger tires add more traction to the surface, making them less likely to slip. Even with the lesser likelihood of slipping, caution should still be used.

Fall Bike Riding Tip 3: Stay Visible

For fall bike riding high visible clothing and saddle bag gear are easier for motorists to see.

For fall bike riding, high-visible clothing and saddle bag gear are more accessible for motorists.

Dusk is coming earlier and earlier as the fall season continues. This means the evening intrudes on some great riding opportunities in the daylight. In contrast, some days will be saved temporarily when we fall backward an hour on Sunday, November 5th this year. The time change can still negatively affect cyclists.

Also, when times change, it can affect a person’s sleeping routine, leading to a lack of sleep. This sleep deprivation may make people less attentive while driving or riding a bike. You would think that people would sleep in, being the 5th is on a Sunday, decreasing the number of accidents. However, cyclists and other pedestrians should be aware and extra cautious for the next few days. Why? Because people need time to adjust to the time change. According to a study done in Sleep Medicine and The Royal Society for the Prevention of Accidents, it has been found that there is a significant increase in fatal accidents following the changes in daylight savings time when it occurs on a Sunday or Monday.

This means that staying visible is even more critical than usual. This isn’t limited to the morning but throughout the day, whether on the road or trail.

You can do this in several ways, depending on what you are comfortable doing. Plus, the more you do, the more you increase your visibility.

Wear Light or Neon Colored Clothing

Wearing bright colors will make you stand out. If someone doesn’t see you begin with, the color will catch their attention, and they will find it easier to keep tabs on where you are. On the other hand, wearing dark colors isn’t recommended. Dark colors can blend into the dark and reduce your visibility. Natural dyes can also blend you into the background or sidelines, making you less visible.

Wear Reflective Clothing

Reflective clothing is a must when cycling in the early morning before there is much daylight or in the evening. This way, when the headlights on a car shine on you, you’re immediately recognized.

Add Lights to Your Bike

For fall bike riding add bike light front and back to be more noticeable.

Add bike light front and back for fall bike riding to be more noticeable.

Did you know it’s a law to have lights on your bike? You have to do it, but you should do it because you’re interested in protecting yourself and staying safe.

It’s important to note that lights aren’t required for daytime riding. However, since we never know when it might get dark out, and we can’t plan for all those times when we ride late at night, it’s essential to have a light handy. If it’s already attached to your bike, then it’s something you don’t have to worry about!

Unfortunately, there are no excuses if you get pulled over by a police officer for riding in dark conditions without one. Every state might have slightly different bike-light laws (with many similarities). For bike laws and more about lighting here in Minnesota, The Department of Transportation has a condensed document to review.

Fall Bike Riding Tip  4: Check Your Tire Pressure and Tires

As discussed earlier, leaves can hide different items that can puncture your tire. It’s not always avoidable, so you must check your tires occasionally. This shouldn’t be limited to the fall and winter but should be checked every time before you begin riding. Doing this allows you to catch any problems sooner rather than later.

Another thing to check is tire pressure. While fall isn’t as cold as winter, the cold can still alter the tire pressure. So, checking the tire pressure before each ride is best.

Fall Bike Riding Tip 5: The Usual Tools

Remember to bring the basic repair tools for your bike adventures! If anything happens, you will want to ensure you have all the necessary supplies to fix it. To know these, check out our article about the tools you should have for any ride.

With these tips, you’re sure to have a great and safe extended season as you continue to ride your bike through autumn.

Keep safe, have fun, and ride on!

5-tips to extend a Lithium battery life for e-bikes and other power tools

by Jonathon Monk

Electric bicycles are an increasingly common sight in most countries throughout the world, and here are some tips to extend the lithium battery life.

Lithium_Battery-1

Tips for charging your new Lithium Battery

With more and more people choosing to take to two wheels, these bikes offer the perfect opportunity to enhance fitness while playing an important role in helping to reduce the carbon emissions generated by other forms of transport. These bikes are helping to persuade many non-cyclists to start pedaling. However, it is essential to understand that purchasing a new e-Bike or tool with a lithium battery is just the first step.

Extend the life of your Lithium battery

Once you have bought your e-bike or light, it is crucial that you take the necessary steps to ensure that it continues to run at its optimum level, and few aspects of an e-bike are more critical than its battery.

Enhanced technology has seen many electric bike manufacturers utilize the benefits of long-life lithium batteries. While these batteries offer a significant upgrade over their predecessors, it is still essential that specific guidelines are followed to maximize the batteries’ lifespan and run time.

5 Lithium battery life tips

Below I have outlined several e-bike battery care tips that will help you along the way.
1. Owners Manual – Read and follow your bike’s accompanying manual and warning stickers. If you have any questions, call your bike dealer or the company directly and ask.

2. The Charger – Only use the charger supplied with your electric bike or light. Using a different charger can be very dangerous, possibly resulting in fire and/or explosion. So use the charger that came with the item you purchased.

3. Fully Charge – When you get a new e-battery, fully charge the battery per the instructions before you ride the bike.

4. Avoid Extreme Temperatures – Very hot or cold temperatures can negatively affect the battery’s performance and shorten its expected life. Avoid storing and charging your battery in a garage or shed that could be subject to really hot or cold temperatures. Instead, charge and store your battery in a moderate temperature area. (Recommended storage temperatures are 32F – 77F. Avoid exposing the battery to extreme heat, 104F +, for long periods.

5. Storing a Lithium Battery – If you will not be riding your electric bike for an extended period, it is a good idea to store your lithium battery with a full charge. At the three-month point, check the state of charge and recharge to top it off if necessary.

Two more bonus tips!

6. Charging Location – When charging your bike or battery, do so in a dry location where a hot battery or hot charger (should there be a malfunction) will not cause a damaging fire.

7. Avoid Humidity – Store your bike, battery, and charger in a dry location. Water and humidity are not suitable for any electrical device.

Finding visibility for safety and fun in fall’s limited light

by John Brown

Now that fall is officially here, we must keep visibility in mind while staying active amongst all autumn colors. As the days get shorter, while enjoying your favorite outdoor activities this time of the year, the primary forms of visibility we need to focus on are passive and active visibility. Things like reflectors and bright colors are passive forms of visibility, While lights and blinkers are great examples of active visibility. Read on to see where each one is helpful and most efficient.

First Passive visibility

Most autumn bike rides start in the light and gradually evolve into darkness as the rider pedals. In these cases, most riders rely on passive visibility to get them home. Provided your ride is under street lamps or some form of light, that passive visibility will get you home. The most common form of passive visibility is the lowly reflector. These plastic devices are required by the CPSC (U.S. Consumer Product Safety Commission) to be installed on all bicycles sold in the United States. You will find reflectors in two colors: white (front and wheels) and Red (rear).

Additionally, many apparel companies install reflective materials onto their products. Like the reflector on your bike, these reflective materials will take any light directed your way and return it to the source of the light so you are seen. Where passive reflectivity falls short is when there is no light source to activate the visibility.

Several manufacturers make cool winter gloves that are both visible and insulated.

Active visibility

When the area is devoid of a light source, as a rider, you need to create that light to keep yourself safe. For cyclists, Lights and blinkers are the most common devices for light. Where the light and the blinker differ is that blinkers are designed to be seen, while lights allow a rider to both see and be seen.

Great lights are usually rechargeable and use an LED bulb. For riders who spend a lot of time off-road or on unlit paths, these lights are a necessity. While most mount onto the bars or helmet, there are a few companies that integrate lights into the bike or your helmet.

What to use this Fall

For the fall season, mount a pair of lights to the bike (one front and one back). When you get stuck in low light and high traffic, switch on the lights. Even If your route uses a road with street lights for any portion, a front light makes things safer. Overall, think ahead before your next ride and be prepared to ensure you can see others and they can see you.

Being visible and noticed doesn’t end when the sun comes up

by John Brown

Now with spring riding soon in full swing, stay visible and noticed. Wear clothing that makes you stand out to others while riding your bike or walking. Being noticed by others is the key to avoiding accidents. Focus on the two forms, passive and active visibility, to help stay safe. Things like reflectors and bright colors, especially in patterns that make you stand out, are forms of passive visibility. While lights and blinkers are great examples of active visibility, most people focus on nighttime visibility. Though, far more hours are spent in broad daylight riding a bike. Here are a few tips to keep you safe and visible whenever you ride.

Clothing that makes you more visible and noticed

Read on to see where each one is helpful and most efficient.

If you were driving a car which cyclist would grab your attention first?

The easiest way to be visible is to wear obvious clothing. Whereas black may be slimming, it doesn’t offer others the best chance to see you. The most visible color available is high visibility (hi-vis) yellow. It is bright yellow not found naturally and sticks out against the backdrops on most normal roads and paths. If hi-vis yellow isn’t for you, try to wear other colors that would stand out, like bright blue, red, or orange. Better yet, an obnoxious pattern of several above-mentioned colors, so you are sure to be noticed.

The most visible color available is high visibility (hi-vis) yellow.

Lights that make you visible and noticed

Many companies are recommending riders use their lights during the day and at night for a great reason. Active forms of visibility like blinking lights do a lot to attract the attention of others. For best visibility and longest battery life, use your lights in “blink mode” rather than a steady beam.

Reflectors that makes you more visible and noticed

Most cars sold in the US are equipped with daytime running lights. For that reason, the reflectors on your bike will shine back at drivers during the day and alert them to your presence. Beyond the standard reflectors your bicycle comes with, think about adding adhesive reflective tape to bags, helmets as well as your bike.

Position

Being visible while riding can be as simple as your position on the road to be noticed. In situations where there isn’t enough room for a bike and car, be sure to take up enough space to ensure no driver could miss seeing you and try to “squeeze” past. Also, ride at a controlled speed where there may be blind corners, driveways, or crosswalks. Additionally, don’t stop in places where others can’t see you until it’s too late.

When making a lane change, signaling your turn and making eye contact with those you are approaching.

Signal

No amount of visibility will make up for erratic riding. Be sure to signal where you are going so auto drivers, other cyclists, and/or pedestrians know where you are headed. When overtaking riders or walkers from behind, be sure to let them know where you are going with a simple “on your left” or “on your right.” Then, give them a moment before passing and ring a bell if you have one.

Kids

Kids riding bikes is something we need to preserve in this digital world. The best way to keep kids on bikes is to keep them fun and safe. Try to have two adults riding with kids if possible, one leading and one following. Be sure to remind children of how and when to signal, and dress them in colorful clothing. Because kid’s bikes are lower to the ground than an adult bike, they can go unnoticed. A flag mounted to the bike reminds drivers that there is a bike below.

Following these tips will limit the chance of an accident and keep your ride fun and safe.

No matter your level of bicycle riding skills, bike lights are essential to make sure you have a safe ride, day or night. Bike lights aren't only needed when the sun goes down.

Bike lights will help to keep you safe day and night!

by John Brown, HaveFunBiking.com

No matter your bicycle riding skills, bike lights are essential to make sure you have a safe ride, day or night. Lights aren’t only needed when the sun goes down. In fact, lights are super helpful when riding in conditions where traffic may be present or limited visibility. That’s where proper lighting comes in. Plus, many states, like Minnesota, require you to have lights on your bike. The two types of bike lights on the market are lights that allow you to see and lights that allow others to see you.

Bike lights that Help You See

Lights that help you see are usually high-output LEDs that cast a focused beam of light in front of you. These lights start at 600 lumens and increase output from there—their size and run time depending on the battery. For example, rechargeable and battery-operated lights are usually larger, while lights run by a generator are smaller.

So, how do you know which one is best for you? It all depends on how often you plan on using it. The battery-operated kind works well as backups in the rare chance you get caught in the dark. The rechargeable kind is best if you plan to use them regularly and want to save on the cost of buying batteries. If you ride long periods in the dark, it’s hard to beat a generator-powered light. Any of these lights will be great for unlit roads, trails, or paths.

When you look to buy a light, they are all compared by the lumens they produce. What’s a lumen, you ask? Well, lumens are the most popular description of brightness. In the past, lights were measured by the amount of energy they consumed (watts), but with LEDs that get more light output with less power consumption, measuring brightness with watts has become impossible. Simple rule, more lumens equal brighter light. As a comparison, the iPhone flashlight is less than 10 lumens.

Bike lights to Help People See You.

The lights designed to be seen use an LED to flash intermittently when turned on. Surprisingly they can be as small as a few coins stacked on top of one another and have run times in the hundreds of hours. Additionally, they are usually easy to move from bike to bike if needed and are great for city streets and well-lit paths. Some riders are now finding added security in running these lights during the daytime.

Reflectivity

Another great way to ride safely in the dark is to use reflective products. Thanks to advancements in reflective technology, you can find completely reflective clothing, looks like normal fabric and glows when hit by light. There are reflective stickers you can adhere to your bike and reflective bags you can mount behind the saddle or on your handlebars.

How to be Seen

Visibility is about safety, so it’s best to use a belt and suspenders approach. A headlight will allow you to see and be seen from the front. Match that with a reflective jersey, and you become visible from the sides as well. Mount a rear blinker, and you become visible from 360 degrees.

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.

A dynamo light is an upgrade you should consider for this fall!

by John Brown, HaveFunBiking.com

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.

Rotllicht "red light" off the bike is great for visibility.

Rotlicht: Out of the box review for a one of a kind rear blinker

by John Brown, HaveFunBiking

Along with Lupine’s SL-A7 we received a smaller package containing the Rotlicht (German for “red light”). While on the exterior it looks t be a normal red blinking light, this little package houses big features. With the brightness of 160 lumens (higher than some front lights) and an internal rechargeable battery, this light might just be the best rear blinker ever made. Read on to see what else is hiding inside.

Unique blinker light features

One thing this light does that is totally unique, it gets brighter when you stop. Thanks to an accelerometer inside, the Rotlicht can sense when you are slowing and increase its output. Additionally, you can preset one of 20 different output settings (4 blink modes with 5 brightness levels).

Construction

As far a blinking lights go, this light is in a class by itself. Most lights are injection molded plastic, with poorly fitted o-rings designed to keep everything water resistant. How the Rotlicht differs is its CNC aluminum case. The lens and electronics are bolted into place and all the seals are snug and sure to be waterproof (although their site doesn’t give specifics as to how waterproof it is?). Also, the USB charging port is located on the back of the light, well protected from the elements, it uses a custom rubber plug to keep it dry.

How it fits

One of the best parts of the Rotlicht is how secure it mounts. The aluminum case acts as a great foundation for the lights long rubber pads. Those pads keep the light nearly immovable when mounted with the included rubber strap. I have ridden this light for a few weeks without it slipping down or twisting on the seatpost.
