Retractable Cable Combination Lock

[UPDATE 6 January 20014: Unrecommended! See video of how Mark cut the cable with a pair of scissors.]

You ran into the store for one minute, came back out and your bike was gone! Or your skis, or motorcycle helmet.

You know that big, heavy, secure lock you never carry because it’s too big and heavy? This is the compromise solution – easy to carry and easy to use. This lightweight cable lock fits in your pocket and prevents “casual theft.” Let them steal someone else’s bike/skis/helmet (not cruel, just realistic). The retractable cable extends 24 inches.

I’ve been using these for about 10 years or so. Squirt a little WD-40 into it once in a while to keep it from freezing in the cold. Replace it at the first sign of balkiness (it’s cheap enough).

Trixie Bike Multitool

I’ve had a fixed gear bike for a few months, and on a friend’s recommendation, picked up the Trixie. Pedro’s has found a way to cram just about every tool needed to work on a fixed gear bike into one tool, whether it’s a roadside emergency or you are working on your bike in the garage.

It’s a lockring wrench – fixies have a lockring that keeps the rear cog in place. Prior to owning the Trixie, I went through every tool I had in my garage in an attempt to tighten a loose lockring. I ended up on a trip to the bike shop.

It’s a 5mm Hex wrench – useful for handlebar and seat adjustments, and the jackposts for a water bottle cage. I hear it can be used on brakes too, although no self-respecting fixie rider uses them.

It’s a 15 mm box wrench – you need one to tighten the tires to the frame. No quick-releases on my bike!

It’s also an 8, 9, and 10 mm box wrench thanks to the slot in the handle. The 8mm is handy for chain tensioning, but I haven’t needed the 9 or 10mm yet.

It’s durable – 5mm thick treated steel – and portable. It can be mounted on the water bottle jackposts and comes with wingnuts to replace the jackposts if you so desire. I personally secure mine to the underside of the seat.

Lastly, and most important, is the included bottle opener, so you can reward yourself after the job and ride are complete.

Knog Marker Light

When riding after dark you really want some good marker lights for your bike. (A market light is a blinky light that *helps* drivers see you when riding at night.) I find, though, that most of these lights are either too big, or they use short-lasting and hard-to-find watch-type batteries.

But more and more companies are making USB rechargeable lights. Knog in particular makes a great series of surprisingly bright LED lights for your bike in soft silicone that recharge in any USB plug. This also means that you don’t have yet another wall wort to lose, and you can always do a last minute charge at work or even in the car.

These lights are also low profile and light enough to just leave on your bike so they are always there when you need them.

Park Tool Cyclone Bike Chain Scrubber

I’ve been bicycling for years but just recently purchased the Park Tool Chain Scrubber. This may be the simplest way to clean your bike chain and it can be done without dismantling anything (on most bikes).

The tool has evolved and been improved over the years from when I first saw it, with a smallish reservoir and three “spoke style” brushes, to what you see today. The first brush the chain encounters scrubs the outside of the links and the next two brush the inside and rollers. Before exiting the chain runs across a sponge to reduce the amount of cleaner remaining on it. There is a magnet in the bottom of the reservoir to pull the ferrous particles out of suspension and the entire thing comes apart for easy cleanup (strongly recommended to keep it working at its best).

Honestly, I can’t remember the last time I had this much “fun” cleaning a bike chain. Previously. to get a chain really clean. I would remove it from the frame and soak and brush before hanging to dry and then re-installing and adding chain lube.

The kit I purchased also comes with a hand brush that has a semi-circular toothed handle for digging the crud out from between the rear cogs and a bottle of citrus based cleaning solution. Support your local bike shop, ~ $30 or ~ $25 online + shipping.

Lezyne Bike Tire Patch Kit

After years of carrying around a repair kit of bits and pieces for my biking excursions I decided to upgrade and replace almost all my bike gear. I came across this patch kit in a shop in London. Its a small aluminium sleeve containing adhesive patches, a tire boot (for those occasions when you need to patch the tire as well as the tube) and a scuffer to rough up the area of the tube before applying the patch.

The package also includes two strong nylon tire levers, which double as end caps for either side of the sleeve, neatly ensuring that everything stays together in your pocket or bag. This little kit, together with a spare tube and mini pump, is all I need to carry out when I go for a ride. The sleeve comes in various color options and I have a seen a few different shops sell them custom branded with their logos on.

Planet Bike Lunar Levers

Every cyclist should have a flat kit to enable them to deal with a flat tire.  Most kits include simple levers to get the tire off the rim and a set of patches for repairing holes. The Lunar Levers combine these two needs into one. The levers themselves are better designed to help you remove and remount a tire than standard levers. Ingeniously, the levers store the patch kit inside inside the levers themselves, snapping together, forming a single unit, saving space.

Skuut Balance Bike

Balance bikes teach balance before pedaling. Learning to pedal is easy if you know how to balance. Learning balance is fairly easy, too. But learning them concurrently is hard. With a balance bike instead of a trike or a standard bike with training wheels, it’s much easier for a child to learn the balance, steering dynamics and handling required to ride a bike. My son, at 2 1/2, can go at least a mile on his Skuut bike, and is learning all the skills he’ll need, so that when I get him a normal bicycle, with pedals, he won’t need training wheels.

The design of a balance bike is brilliant—it’s actually similar to the design of the first bicycles (velocipedes) that had no drivetrains. The particular brand of a running or balance bike for kids is not of much concern. Cool Tools previously featured the Likeabike, which was imported from Europe and lovingly crafted, but notably expensive. You can find cheap $50 metal balance bikes these days, but we use the current wooden standard Skuut which is good enough quality for $85.

Respro Sportsta Mask

As an avid cyclist who cycles to work everyday, all year round, I’ve had a lot of throat infections throughout the years simply due to the cold air. A buff scarf is great for isolation but hard to breath through, gets humid and inevitably ends up frozen.

Recently, I discovered Respro’s Sportsa Mask which is made from neoprene and filters the air. Inhaled air is not so cold anymore and only influences breathing a little bit (you get used to it). After my 35 minute ride there’s some condensation on the outside valves. I can see this freezing when temperature drop below 0C, but Respro also has an X-treme Mask for cooler conditions.

It’s proven itself time and again as it enables me to bike outside when its cold, while also filtering the air.
