Can I assemble a bike?
I plan to buy a fixed gear bike with hand brakes. I noticed that I can buy nearly the same bike on line, delivered to my door unassembled, for about half of what I would pay at the bicycle shop. According to Amazon commenters, it isn't hard to put together. But I don't know anything about assembling hardware. I'd hate get stuck halfway through and need to call on my know-it-all upstairs neighbor. Has anyone assembled a fixie and can you say how difficult it would be for a good reader with poor mechanics? I appreciate your advice.

Depends on how mechanically inclined you are, what tools you have at your disposal, how patient you are, and how willing you are to seek out and follow instructions. I'd say it's extremely simple, but my experience makes me biased.

Also depends on what needs to be assembled. For example, if the bike only requires installing the pedals, turning the handlebars and tightening it, etc., then you should be able to do it yourself. However, you'll have to make adjustments so the bike fits you properly eg. seat height, bars.
Anyone who can manage a can opener should be able to final assemble a fixed/single speed.....even your know-it-at neighbour shouldn't complain too much helping out......

I'm sure you can do it, Speedway. You have all winter to figure it out!
You will know your way around your new bike much better than a rider that took delivery of a fully assembled bike.

Almost anyone can "assemble" a bike out of a box and it will likely ride, but seasoned mechanics almost always find something that needs a little tweaking or additional adjustment beyond basic assembly. How discerning of a rider are you? Some won't care or even notice if there are minor issues while others demand better.

I’d say go for it! You just might enjoy it and find it empowering. The good news is there’s really not much to a fixed gear, the only thing I see is cutting steerer tube and BB install, the BB if not installed already is pretty easy just need the right tool. Steerer tube 25 bucks @ lbs
If you do not have tools some of the money your saving would be spent on tools. But once you buy them you have them, also you can do adjustments and have a better understanding how your bike works. The mechanic sub here and YouTube and reading a lot also park tool has resources. Go for it take your time, have fun👍

I've rarely encountered a new-in-box bike that didn't need the wheels trued to some degree.

If you have the tools and knowledge (which it sounds like probably not) then yes you could do it. However an Amazon bike is going to probably need some serious work (if it doesn't come broken) and likely the people putting it in the box are literally trying to shove it into the box as fast as possible and putting it together just barely enough because they are probably getting paid by the bike so quality is not important nor is safety or anything like that.
Nearly the same bike is a scary proposition in this case because I can buy two bikes that on first glance look similar enough but are vastly different hence the difference in price. Plus with the bike at the shop it is built and ready to go with warranties and support behind it. Some companies really don't have warranties so if the bike gets built poorly who cares they are long gone from the equation or expect Amazon to deal with it (poorly in the case of bikes) and the ones that do will likely have it assembled by a professional mechanic to validate the warranty.
Keep in mind time is money! Though if you did want to learn a single speed or fixed gear would be the easier bike to learn on but without the proper tools I will still want to bring it to the shop so again time and then also more money.

You should have no difficulty. You will learn things along the way and be proud of the result. You will also feel more confident embarking on long rides knowing you can fix anything that goes wrong.

It depends on who you buy the bike from and how much you pay for it. For example, I bought bikes from Wabi and Universal Cycles which were first assembled by professional mechanics in a bike shop, and then broken down sufficiently for shipment. Everything was already adjusted and tightened properly, and all I needed to do was install the wheels, turn the bars 90 degrees and install/adjust the saddle and seatpost. Even then I needed a set of hex (allen) wrenches. However, if you buy a cheap bike from say bikesdirect or on Amazon, you will receive a bike that was partially assembled and boxed in China without any adjustments that you will need to fix yourself with proper tools and no doubt some pieces will be defective or missing as well. In the end you will spend just as much as if you bought the bike from your LBS, and will still have an inferior product. So, while everyone says go for it, I say first get a bike at an LBS, learn how to maintain it yourself, then graduate to buying a bike online and assembling it.

IME: new bikes out of the box often require hub bearing adjustments, as they come way too tight from the factory. wheels often have spokes that are a bit loose after they have been de-stressed.
grease the seatpost!

With the possible exception of high end bikes most bikes are never fully assembled or tested before they leave the factory. The frames and wheels are assembled on different lines, and packed together in a box. Final quality control is up to the retailer or customer. Like the Ford Model T at its peak of production.
I'd treat any new bike like a used bike in good cosmetic condition. Notably I'd check the lubrication and adjustment of the bearings, the tension of the spokes, and the adjustment of the brakes. These things will add greatly to the reliability of the bike, and are not an insurmountable DIY task. They would not stop me from buying a bike.
And you've got to learn basic maintenance sooner or later anyway.

Skip the Phillips screwdrivers people JIS, ALWAYS JIS! Also some of those tools I would skip at least in a basic tool kit some of it can be handy but a lot of it is just cool tools that are nice to have for a general home repair tool kit and aren't as needed with bikes but can be used.

I think the tool list was useful, but excessive and possibly frightening if you're just assembling a starter bike. The fairly widespread advice is that you can use basic household tools for a lot of things, and buy the special purpose tools as the need arises. This has been my practice for 40+ years. More info could be provided if the make & model of the bike were known.
Of course if having a fully equipped shop is a hobby, then whale away.

The problem is that a cheap starter bike requires more than simple assembly. It also requires a lot of adjustment, such as wheel truing and tensioning and wheel bearing adjustment. Wheel truing is not easy without a truing stand, and wheel bearing adjustment requires cone wrenches. And then there’s little details such as trimming brake cables, which requires a proper cable cutter, since an electrical wire cutter won’t work. How about the crank arm bolts, which are never tight enough from the factory, but you also don’t want to overtighten them, so you need a good quality torque wrench. How are you going to drive the star nut down into the steerer tube, so that you can cut the steerer tube to its desired length ? How are you going to make a clean square cut of the steerer tube without a hack saw guide and sturdy bench vise ? Many people who’ve bought cheap bikes online have ended having to take them to an LBS to get them properly assembled.

do it! worst case scenario you bring it to a LBS to have it assembled or buy a friend lunch to help you. Fixed gear bikes are the easiest to assemble as most of them arrives 80% assembled.

Assembly is different then tuned and ready to go. Putting a part on a bike is not the same as making sure that part is properly installed and torqued. Not saying one couldn't do that themselves with the proper tools but bikes need more than just throwing parts on to be safe and ready to go.

It's a fixed gear. As a minimum, it'll be:
- mount front wheel
- mount handlebar in stem
- adjust headset bearing preload
- install front caliper and/or front brake cable
- grease and install saddle/seatpost and fix clamp bolt
- install pedals
- inflate tires
Additionally, as others have mentioned, you may want to:
- check front and rear hub bearing pre-load, adjust
- check and adjust for front and rear rim true
Fixed gears are about as simple as a bike gets. Give it a shot.
- mount front wheel
- mount handlebar in stem
- adjust headset bearing preload
