First you need to get borderline drunk and start browsing AliExpress late one night, then forget all about it by morning. A few months later a bike wheel with a hub motor and controller unexpectedly show up by courier at work. This reminds you why you bought that lipo battery months back thats way too big for any of your quadcopters. Then you spend an hour or two the next Saturday afternoon bolting the wheel and ziptieing the wiring and controller onto the $50 eBay mountain bike you bought a few years back when you decided it was "time to get fit" - which had been sitting in the garage ever since after having been ridden only once or twice. You then notice the battery is an _almost_perfect fit into the drink holder, and you can make it into a perfect fit but putting the battery into a stubby holder! Win! A bit of work with the soldering iron having robbed connectors and heatshrink from the quadcopter parts bin, and it's ready to go. You then hop onto the bike and cruise up all the nearby hills grinning like a loon and laughing out loud.

Im pretty sure that covers all the important steps. If you need me to check my notes about exactly what you should be drinking to get the right sort of AliExpress ordering buzz going, let me know - it was _probably_ bourbon ;-)
