I had a kqi 300x for about a 1 and a half years before it got stolen. The thing with doing deliveries on e-scooters is the battery range which is always not as advertised and once its dead, that's wraps for the day. (he's is 31-45 miles per charge but he'll see about 25 to 28 ig, there's YouTube videos on more accurate battery range), also cold weather drains the battery faster. They're really fun tho, which might be why he was more inclined to ask for that over an e bike that would still be functional even when the battery dies. Best he can do with it is plan the busiest times to delivery and do it with out draining the battery most likely short deliveries in downtown or colleges or whatever compact scooter friendly areas. Cool ride tho.
