I installed a Topeak MTX DXP bag, Topeak Super Tourist DISC rack, Topeak bar extender, 500W headlight, and Hornit (140 dB) horn today. I installed a Serfas Men's Gel seat yesterday with a suspension seat post, gel Oury grips, and headlight. I did 17 miles this morning on my local "Arlington Loop." The rear derailer was also updated from to a Shimano Claris since the original keep messing up and was flimsy. Pedals will be next on my list (since I scraped one bad in a corner this morning) and then smaller street tires (i.e. Hookworms). I think I will upgrade to the 52V battery too in the future and maybe change the cassette and brakes for hydraulic.
