Main types of bicycles are road, mountain, commuter/comfort and fitness bikes. There are more specific types and other names for bike types within that, such as urban bikes (same as commuter bikes), cruiser bikes, dual-sport bikes, hybrid bikes, fixed-gear bikes, cyclo-cross bikes, adventure road bikes (aka all-road bikes, gravel bikes), road bikes, touring bikes and specialty bikes, like BMX.
As you mentioned, it is surprising how often you can get multiple flat tires on while riding, particularly on longer sprints. The tip about bringing a patch kit in your bike repair kit can be incredibly helpful if you’ve already had one flat tire. I agree that all you listed seems like an awful lot to carry, but it’s always better to be safe than sorry, isn’t it?
This is a very basic book and unnecessarily repetitive in sections. It does introduce the reader to the basic nomenclature of bicycles and this is helpful when conversing with others. Unfortunately the repetitive sections were not replaced with chapters on 3 Speed in hub gear drives, or coaster breaks, or a chapter on Adult Tricycles and Tandems and E-Bikes.
Based on what we found, we chose the most relevant items and used them all. To test patches, I repaired holes using four different types of patches, from Novara (REI’s now-discontinued house brand), Park Tool, and Rema. Patching a tube isn’t hard but there are a few tricks, and the key was attention to detail and patience. I was extremely diligent in following proper patch procedure, which includes a thorough sanding of the entire area to be patched (for max stickiness) and properly letting the vulcanizer dry on both surfaces before applying. For the peel-and-stick patches, I went so far as to prep the area with canned air to ensure as tight a seal as we could possibly muster.
Bike Radar gives the Pedro’s levers 4.55 out of five stars and claims they’re the “best out there.” (Can we pause to admire the extra five hundredths of a star the site chose to award it? Very specific.) Aaron Gulley, writing for Outside, states, “I can’t count the number of times I’ve snapped cheap plastic sticks, shredded my hand in the process, stomped around cursing in pain for 10 minutes, and then, insult to injury, been tool-less and unable to get my tire off anyway. That will never happen with Pedro’s.”
Professional mountain biker Rebecca Rusch has been on plenty of long rides and experienced enough mechanical failures to know what makes a fully-stocked repair kit. One of her recent journeys, a 1,200-mile journey through the jungles of Vietnam, Laos and Cambodia along the Ho Chi Minh Trail required the utmost degree of preparedness — “We brought with us a lot of extra bearings, o-rings, stuff that you would never be able to find in Laos and Cambodia. Before I go out on these big adventures, I replace every bearing in my bike, my fork got a total rebuild — everything is in pristine condition,” says Rusch.
I chose to test these four levers after eliminating everything out there that’s not appropriate for a roadside emergency kit. That includes metal levers. They’re durable, but according to touring cyclist Ramona Marks, “Metal tire levers are trouble. It’s possible to rip your tube even with the plastic ones if you’re not careful, so metal is out of the question, and you don’t want to put pressure against the wheel rim with a metal lever.”
It has some useful information for basic repairs... not so heavy on the maintenance side but there is some in there. The pictures and drawings are in black and white, but mostly visible. Only a few are difficult to see. However, they are in 2-dimensions and they don't show you HOW to do the thing, they only show you the general area and the part you want to manipulate. The phrasing in the instructions can be hard to follow without a good visual reference unless you're already a master bike mechanic (which you aren't if you're thinking about buying this). So, buy this for general reference and rely on Youtube for video. The two together are better than either one alone.
Broadly speaking there are two major wheel sizes – 700c for road bikes and 26 inch off-road wheels. However there are a whole variety of older, less common wheel sizes and of course fold up bikes have much smaller wheels altogether. Repairing a puncture is not an emergency! It’s a basic procedure that every cyclist should be able to to perform, but doing it correctly involves more steps than many people realise. Wheel building is often seen as the most artful skill in bicycle maintenance, and separates the professionals from the amateurs but that doesn’t mean you should consider it out of reach. Truing a slightly misaligned wheel is a cycle maintenance job that almost any cyclist can perform.
