Glad you are enjoying the bike!!
One of the great things about electric bikes is that, by comparison with petrol machines, that require almost no maintenance. Apart from the wheels there are no moving parts- no transmission, gearbox etc. The motor is a sealed unit and is brushless- so nothing to wear out.
