A friend bought one of the BWS 50 scooters when Excalibur was selling the Lintex brand scooters, and if you look on Taotao's site, they also have a BWS under 'clearance.' Not the same brand, but identical at leat in looks, and both being Chinese, I am sure they are near identical. I liked my friend's scooter due to the wide wheels/tires. My guess is even on 'clearance' it will cost more than the boring-looking bargain ATM-50 or whatever it is called, but your nephew should ask about the BWS 50 for whatever it is worth.
