My DIY Handle Bar GPS holder

I can be a bit of a “geardo” sometimes, and can be carrying any number of electronic devices at any given time. I have a Magellan GPS that love using for mapping trails out or city routes that I feel are worthy of recording. I have always wanted one of those expensive GPS holder solutions on the market. But just can never justify the price for something that I will for sure smash in the the first one to two months of ownership. So i came up with a cheap replaceable DIY holder for my GPS.

I ‘ll show you how I made it, just in case you you have some kind of electronic Fred gear that needs to be mounted to your bike.
Get one piece of PVC pipe about the length of your GPS. I used 2 1/2 inch, black PVC from the Home Despot.

Now take a jig saw and make a horizontal cut down the tube, making a single straight cut through one wall of the tube. Now here is the tricky part, and it may take you many tries, with many pieces of the PVC pipe to get it right. But hey, PVC pipe is pretty cheap for a 5 foot length.

You have to make the second cut at just the right spot, so that there is some gripping force or “cradle” effect on your GPS or electronic device. The pipe has great has a slight flexibility that it retains no matter how many times you flex it.

Now get one of the many bar clamping reflector/light /bell /last thing fell or broke off your bike, holder things. All of these bar retaining systems share the same pivot which usually is all you have left after it breaks off your seat post or handlebars. So if you’re like me, they are easy to come by and you already have a shoe box full of these things.

The pivot will usually have a bolt going through the center, but for the this purpose you’ll need a longer bolt with a nut and 2 washers.

Drill a hole through the center of the cradle the size of your bolt near one end. You can make make the hole depending on where you want the GPS holder located on your handle bars.

Mount the PVC cradle to the bar clamp with the bolt and nut. UseĀ  a washer on both sides for a nice snug fit.

Do it a test fit and clamp your GPS into the PVC cradle. You want to be sure it takes some force to dislodge it. You can apply pressure from the insides the pipe, and outwards to release the GPS. In my case the the Magellan doesn’t touch the back of the tube, but it your device does, you can throw in some foam to cushion or prevent scratches. This extra space also gives me some ability to tilt the GPS up or down after it been locked to the handlebars.

I softened the the hard edges of the pipe with a knife, to give it that perfect production quality look. You could sand it, paint it a different color or carve it into any shape depending on your level of creativity or prowess with a Dremel or wood carving kit. The PVC is pretty malleable.

I use a couple of 20 lbs fishing leaders linked together, as a lanyard strap hooked to a carabiner as extra security. Just in case the GPS were to fall out on a jump or accidental crash. I usually clip it to one of the brake lines. Unless I’ve got a lunker on the other end, that GPS is going anywhere! Anyway have fun building gang.

Great Downhill Movie Featuring Jinya Nishiwaki

At this time of the year in Winnipeg I like to visualize cycling somewhere warm. While stumbling for bike videos I found this one. I soon found that this YouTube video had quite a bit of traction on the bike forums. People were discussing the video. Was it actual speed? Was that seriously a hardtail? Who is this guy? What kind of bike. I though I would share it with you guys, just because I thought it was an awesome and inspiring video. Great camera editing and soundtrack. Nice moves Jinya.

Who Said You Need More Than One Bike?

This guy has some skills!
To restate an overused quote, “It’s not about the bike”.

I’m sure that road bike is an endangered species at the Whistler Mountain Bike Park. Next up, let’s see him take the A-line all the way down.

Secrets Of Winter Cycling, Float That Front Wheel

Part of the fun of winter cycling is crashing through snow drifts or trying to clear a stretch of deep powder. When going through any amount of snow deeper that 6 inches, it makes a lot of sense to sit up straight, lean back, and put as much weight as possible on the rear wheel. Allow the front wheel to roll over the surface of the snow, instead of plowing through it. You’ll notice the extra speed and reduced effort right away. Steer with only with the tips of your fingers to get a real feeling for “un-weighing” the front wheel. Your rear wheel for the most part will follow in the path cleared by the front wheel. If you start to sink, push down into the pedals to more evenly distribute your weight. Without the friction of the front wheel snowplowing, you’ll have the extra bit of loft you need to get through longer and deeper stretches of snow. Just beware of the rear wheel sticking and then being pitched over the bars!

Another way to practice floating that front wheel is to practice your manuals going over snow drifts or when you’re about to cross plowed snow rutts. A “manual” is similar to a wheelie, but you stand and coast on the pedals instead of sitting and pedaling.

From pedaling speed, hover over the rear brake lever as you pull back on the handles bars. Lean back until you find that sweet spot. Conversely you may only need to clear a small object like curb, pot hole or block of frozen snow, and only need a little lift to get the wheel up and out of the way. If you lean too far, give the rear brake a light squeeze to pull the bike back under you.

If you can get that front wheel over an obstacle, the rear wheel can pretty much follow it, and that goes for summer riding too. Have fun!

Secrets of Winter Cycling, Introduction

Why Winter Cycling?sein river cycling

Cycling in sub-zero temperatures? “You must be crazy!” Any one whose ever rode their bike in the winter is sure to have heard this from some one. When people ask “why would you ride your bike in this weather?”. I have a few answers for them. First off, yeah I’m a little bit crazy, but remember, people do all kinds of winter sports. Imagine commuting to work every day on your snow board or hockey skates. Imagine going to get grocery’s by cross country skis, or tobogganing with your friends on the weekend? How fun would that be right?

Here in Winnipeg most people are content to hibernate in their homes all winter, only leaving the cozy couch to bundle up, pray that their cars will start, then spend 15 minutes practicing their Lamaze breathing, shivering as the frozen auto warms up. This includes most cyclist from “pros” to fair weather cyclists. Even the local bike shops may have only one or two brave souls who will gear up in ride in the ice and snow, if any.

If you’re environmentally conscious you’ll be interested to know that driving your car in the winter is up to 50% more polluting than driving in the summer. The engine is always running a rich fuel to air ratio because of the higher density of cold air. The extra time it takes to get anywhere is testament to that. Think about it? You warm up the car at high idle for 10+ minutes every time you decide to drive. The oil is frozen solid in the equally frozen engine block creating mass friction, and sucking down fuel. Traffic is most certainly slower as ice and snow reduce your traction in braking and acceleration. The catalytic converter isn’t working until the engine reaches running temperature, so until then, the exhaust is spewing out of the tail pipes untreated. I won’t even go into your odds of getting into a fender bender compared to summer. Besides there is great bike parking at the unused bike racks!

There are many reasons why you might want to get out there and ride. Winter cycling allows you to enjoy your favorite sport year round. For a lot of people winter is the off season. A time to increase you BMI, and catch up on all the latest snacks and sit-coms you’ve been missing during the training season. Come spring most cyclists will regret this. Trust me. In the spring you’ll see all kinds of cyclists hitting the streets as clumsy and weak as a new born fawn. Come spring, winter cycling will have helped you become the predator, the wolf, eager eat any gear skipping slow moving commuters. Seriously though, winter cycling will ensure that you stay fit through out the off season, and will give you time to perfect your technique, without having to train for any specific event.

Speaking of technique, winter riding will increase your sense of balance as you navigate rutted ice and take slick frosty corners knowing full well that wipe out is closer than ever. Of course the crashing is less daunting when you have layers of insulation and end up barreling into a 3 foot deep snow drift. Nearly every day the course or route will change as snow drifts form, roads are plowed, (or not plowed) creating new features to play on.

Riding rollers, or spinning endless circles at the local gym gets old pretty quick and you will soon lust for terrain, scenery and challenge. Outside your strength and endurance will increase by leaps and bounds as rolling resistance is increased due to frozen bearings, studded tires, deep snow or having to carry your 50 pounds of winter beater bike up stairs and to the top of snow hills. Just think about how easy riding in the warm summer rain or riding into a relentless headwind will be once you’ve braved your first winter of riding!

Winter cycling requires a paradigm shift in thinking. Winter cycling is not about racing, or stunting (well it can be) but more about survival. The most important thing to remember is to dress for the conditions. And always pack an extra layer in case you have to stop for any extended amount of time. A lofty vest is perfect, made of down, or synthetics like primaloft is great if cases of bike failure. You want to be comfortable, well at least mildly comfortable? With the temperatures and wind chills you have to deal with, winter cycling is closer to mountaineering than any other sports I can think of, well at least in Canada. In fact I have to laugh at what bike companies call winter cycling gear. The could learn a lot from mountain climbing crowd.

So get out there and get some fresh air! I grow tired of breathing the same recirculated air in the home and work place. In the next articles I’ll go into my philosophy of winter riding, clothing and gear so that you too can get out there and be one of those crazy guys who rides his bike all year round.

PS: don’t forget a thermos of hot chocolate!
