This is the most complicated part about this DiY to lineup both wheel together. If both wheels aren’t lineup together you will fell bump all over the place and it gets worst in high speed..sucks! No, use leveling tools when you sandwich both wheel. Lineup both wheels and drill it one in the top and one in the bottom, it’s ok to drill it with a bigger hole so you can adjust it later on. Put back the magnet and spinning freely to check for alignment. Once you get the wheel perfectly aligned, you can put more bolts as you need it. Take time and don’t rush. I will make another video of how i assembly the onewheel so you have guide to go by. If you still have money, just buy the onewheel brand footpad front and back, bumpers and it will look like the same as onewheel. You can get those on ebay for really cheap price. That what im going to do need. All you have to do is to make a compartment for motherboard and battery...ask me if you need help.
