Patch kit:   Patch kits are easy to use, light and compact, and if you get more than one flat on a ride (it happens more than you’d expect), it can save you when you’ve already used your spare tube.   Plus, on a rear wheel, patching a tube can be faster than replacing it, as you can often do this without removing the wheel at all.  Another upcoming post is going to show you how to patch a tube.
These are some great ideas, especially the simple ones like bringing a garbage bag. That’s something so easy and cheap that it’s easy to forget entirely, but as you say, it can make a huge difference in the right circumstances. It’s also good that you discuss some minor bike repairs. That’s another thing that can salvage or destroy your ride. You want to be as prepared as possible for the best possible experience.
We rented a tandem bike from here for an hour, and they were super chill! We dropped by on a Sunday and decided to go eat first; Andy, one of the owners, was awesome about holding the bike for us while we went to eat before renting. We enjoyed our ride for just over an hr, but Andy was also super relaxed about our return time and only charged us for an hour. We had a fantastic time and would definitely recommend renting bikes from here!
If you’re going to use the chain whip you just made, you’ll also need a way to get that cassette off. A lockring remover is a must-have; unless you use one of the shady removal methods I’ve seen on the internet—which I wouldn’t necessarily recommend unless you don’t care much about the condition of the wheel after you use them. I recommend Park Tool’s iterations here that cost about $6, but you’ll need to buy the specific one for your brand/type of cassette. (By the way, I’m assuming you already have an adjustable wrench laying around somewhere to use with this tool. If you don’t, well, you’ll need one of those too.)
Over the years, I’ve come across plenty of articles that claim to tell you how to build up your cycling toolkit for cheap. Somehow the word “cheap” stops recurring in the long list of “essential” bike repair bits and pieces. The truth is, there is no real way to build a whole shop of tools all at once without plopping down a few hundred bucks. But in an attempt to show everyone that not all of us truly need a full complement of bike tools, I present the truest, most budget-conscious, and barest of bones options to you.

A plastic garbage bag, or $2 disposable poncho:  Just in case of an unexpected downpour or getting caught out after dark.   More than once, I’ve gone for a ride on a beautiful day with a perfect forecast, not taken a jacket and had the weather go south on me.  Being able to cover up can mean the difference between just mild discomfort or a freezing cold, shivering ride home!
I brought my bike into Kyle's shop to fix the noise in my rear wheel. The mechanic suggested that I need to overhauled the rear hub for $30. The next day the noise came back even worst. I brought it back to the shop and they said it was the freewheel driver not the hub that needed to be work on and it would cost me extra $30 to overhauled it again plus the part to fix it. At this point I walked out of the shop and took my bike to David's world. The mechanic at David's world took a quick look at the rear hub and indicated that the axle was put back too tight when Kyle's mechanics were working on it and further identify the issue. I ended up paying David's world the $30 plus part to fix my bike, but the major different is that David's World has 30 Days services warranty claim. If you have any issue with your bike within the 30 days the service was performed you can bring it back and they will fix it no question ask.
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.
