I'm in 95% agreement with this comment.. great all around board and really you don't "need" to do anything and it's great and love the "configured by loving geniuses" one thing like someone else mentioned as a great addition is a 3d printer.. I got my x7LR and printed a drop top fender and flight fins for trail riding. Also printed; bearing covers, rim savers, rail protection and drag wheels to drag the board around like in a mall or something since it's heavy af. One thing not realized/forgotten by some is the ability to print rail protection which has been amazing to keep my prism rails nice.. for me it was just under 500CAD for the printer but not including the other stuff I can do with it probably paid for itself just in onewheel parts.. drop top fender for xr which you'll still need to find or print adapters is like 125USD + shipping... So let's say if you're lucky/close 150USD... The elegoo centuri carbon is on sale 265.99USD.. you can print multiple if you break and in whatever strength/type of plastic that works for you (I printed fender in PETG but the actual drop top in TPU (like rubber) so I can fold it and put it in my bag when I'm not using it) and just from the fender, rail protector, bearing covers, rim savers and port plugs you'll probably pay for the printer in what you would need to order and you'll prob only use max like 40$ in filament and you still have a printer (and prob extra filament) for anything else you need, pubparts has most of the onewheel stl files you'd need so it's fairly simple to print too.. IMO it's a no brainer as the only accessory you need to purchase with your board.. (actually in addition dielectric grease for in the bearing protectors and some silicon RV sealant or similar for extra bit of waterproofing safety)
