I bought one of these. I was only visiting the family for 3 months and they suggested perhaps I buy one of these. For their use I suspect it was a waste of money, too noisy, too slow, too uncomfortable. But I loved it. 50km flat out on the straight I stayed on the main left lane not the slow left lane until I could see someone traveling too fast behind me. How much are they now. I can't remember how much I paid, could be 30,000 baht 14 years ago.
