Reddit reviews Doubleshot 2 Black & Raw / Blue Spring

I would not get those (https://www.amazon.com/dp/B00811Y3MG/ref=cm_sw_r_cp_apa_XWWMzbYEXVNC9) -
SPD SL is the road cleat an not very walk-able as they stick out the bottom and generally cannot be recessed into the shoe. I'd recommend SPD (2-holes like a mountain bike or touring shoe) not SPD-SL(3 holes) for walkbility and the best bet for a commuter shoe if you don't want to change shoes at work/school.


If you want a cycling shoe that you could wear to work, I'd look at a lace-up touring shoe like the Pearl Izumi Alpine Seek that are SPD (2 holes) not SPD-SL (3 hole) compatible.

Here are some other options - https://www.cyclingabout.com/stylish-spd-cycling-shoes-which-look-casual/


You could also get mountain bike flat shoes that have a stiffer sole for more efficient pedaling but no cleat.


Pedals:

You may want to look at a double sided tour pedal that lets you ride with standard flat shoes to commute or clip in like the Shimano A-530 (https://www.amazon.com/Shimano-A530-SPD-Pedals/dp/B00AAOIAQC) or Crank Bros Double Shot (https://www.amazon.com/Crank-Brothers-Double-Pedals-Spring/dp/B016OQXZG4/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1503334666&sr=1-1&keywords=pedal+bros+double+shot).


If you plan to bring a change of shoes, you may want to look at a doubled sided SPD pedal which makes it a bit faster to clip in, like a shimano M520 (https://www.amazon.com/Shimano-Unisex-PD-M520-MTB-Pedal/dp/B004L1CLSS)

A WTB Speed (I think) , I think the ~$40 WTB road bike one.
The one that came stock on my low level FX got too soft after little wear. It was springy and soft, which felt great in store, fine on short commutes, and not so good on hour rides. It quickly got too soft for anything and offered no support. After some research, at the time WTB seemed a good choice for a budget friendly seat for my commuter. It’s held up pretty well considering the abuse.

For pedals, I have the Crank Bros Candy 3. It’s what I have on my mountain bike and I generally like them. I kinda wish I would’ve done their half platform version though.

Some helmets offer better air flow, comfort, and possibly better protection with systems like MIPS, but these can be found at any price point. People pay a premium for branding; your helmet is fine.

You don't have to spend hundreds on pedals/shoes. First figure out if want SPD or SPD-sl. I recommend SPDs, or mountain bike pedals, due to the range of affordable shoes, easier clip action, and the ability to walk normally. The Crank Brothers Double Shot 2 Pedals will let you ease into clipless by letting you ride however you want. Shimano sells a similar pedal for around $30 as well that might look better on your bike.

Jerseys are cool, but not necessary.

One of the most important things when starting off is finding the best saddle for your ass. Work with a shop for help finding the right one.

Same as others have said here. SPD clips with MTB shoes as those have treads that allow you to (sort of) walk.

I've had these pedals forever (https://www.amazon.com/Wellgo-Shimano-Compatible-Multi-Function-Mountain/dp/B00E7UZBNA/ref=sr_1_3?keywords=wellgo+dual+sided+spd&qid=1566833564&s=outdoor-recreation&sr=1-3 )

although if I were still riding clipped in in the city, I would probably go with these as I like feel of egg beaters much more.

The cleat on an egg beater is about the same size as an SPD one.
