Well, I recommend not making a big hassle and riding and enjoying the ride instead. Forum members (myself included) have a tendency to suffer from GAS, being unable to use something as from factory and instead constantly trying to "enhance" it - whatever that means is up to the individual taste. But if we are honest: Most of those "enhancements" are not necessary - we do them because we like fiddeling around with stuff and because we do not know what else to do with our time. The downside is that we try to assimilate newbies and make them believe they will die instantly if they won't do a gazillion freaky mods on their new bike before the first ride. Let me tell you a secret: You won't. You don't need to buy anything, you don't need new tools, you don't need to train strange mechanical exercises. Simply ride and over time you'll find out what you are missing if anything. In the really improbable case something goes wrong during your first rides just hop on the bus - it is a Brompton after all. They fold.
