I'd second the lights, the lock, the tube & pump (mine's lyzene), some screwdrivers & wrenches to change the tube. CO2 cartridges are too small for 2"x26" tubes or bigger. I find patch kits useless. A bag to keep them & the lock in. I use a 6' SS industrial 3/8" sling that wraps around power poles gas meters & trees, but your town may have civilized bike racks that accept a u-lock (mine does not). Avoid bike vendor & master cables, so soft you can cut them with a $23 tool. I'd negate the padded shorts, I gave those up 30 years ago & I ride 30 miles frequently. I use cotton undies. I wear polyester/cotton work pants & long sleeve shirts, that have saved my knees and elbows on numerous falls. DIckies, or redhat. Gloves, the $1 polyester ones saved my skin at 25 mph onto gravel. Also prevent sunburn. I don't like tire sealant, but I don't live in goathead thorn territory. Clogs up the stem when you want to deflate the tire to tighten a spoke or change a chain or something. A cell phone that fits in your pocket, if you wake up in the ditch after being hit by a car. Having a smart phone on your bike won't help you there. My brother fell off a wall mowing and broke his neck. The apple phone was in the truck. He also stranded himself on the roof when the hi-lift quit, no phone. Tracphones are $8 a month after the first 6 months.
