Reddit reviews Planet Bike Cascadia bike fenders - 700c x 45mm (black) (maximum tire Size 35mm)

I have a Trek 7.2 FX and got Planet Bike Cascadias. Totally worth it.

If you're on a budget (after buying everything else) what I did was I bought a small flashlight that is compatible with 18650 rechargeable lithium ion batteries for pretty cheap and that works pretty well for general purposes. The battery is powerful enough to provide visibility while riding through the city. I wouldn't use just a regular flashlight with cheap batteries though.I use a bungee band to tie it on to the handlebars and it works very well (you can see it on the picture I posted earlier).

This has also been useful for night time riding and getting a flat. I can easily remove the flashlight and use it to see what I'm doing.

I also highly recommend the road morph g that zedmartinez recommended. It's PERFECT for cycling. I was looking around for a small pump with a hose and pressure gauge and that was the only one that fit the criteria that was any good.

As for fenders, they don't come with the window tourist (if you decide to get it). I got these fenders and they're perfect. They have a mudflap, are sturdy, and most importantly they look pretty good.

That's pretty much how I started my 2 mile commute in 2015. I went reading and bought the Wirecutter's reccommendation at the time, a Trek 7.2 (though I did go for the 2014 7.4 Disc, since my shop had it on a good sale). I added fenders and a kickstand immediately, grabbed a cheap (but safe) Wal-Mart helmet and lights, and started riding when the weather was decent. As I needed them, I added elastic, reflective ankle bands to keep my jeans out of the chain, got a set of decent gloves for cooler weather, a rear rack and expandable trunk bag, upgraded my lights, and bought a cheap bike computer from Aldi.
 
After a few years, I had a better idea of what I really wanted, so last fall I sold the hybrid and picked up a gravel bike to get off the 50mph highway and onto the gravel shoulder and replaced my helmet with a more comfortable and better ventilated one. I moved over the rear rack, bought new, larger fenders and a kickstand, but didn't bother with the computer and just got a handlebar phone mount since I track everything on Strava anyways.
 
Of course I don't NEED all of this to bike commute, but it makes it easier/more comforable/etc. to do so. The only thing I've regretted is the fancy gloves: they work just fine, but I could have spent half the money and gotten something just as well suited to my needs. Thankfully I'm in an area with basically no bike theft, so I just use a cheap cable lock on the rare times I even bother to lock it up.
