A 4 inch Hero stem extension. Recommended for riders over 5'10". This will bring the handlebar 4 inches higher vs the standard height. Install on top of the stem, below the handlebar clamp. Installation is fairly easy and only takes a few minutes. Will not work for S10.
When it comes to the battery, Hero scooters are equipped with quality DMEGC cells (used in electric cars) and LG cells. All Hero scooters now come with a certified 4A charger with fan. Charge you ride fast!
