Glad to hear from someone else with the lovable b*stard of a Brompton wanabee. I do like the internal gear hub. Thank you for the suggestion of getting a new bike. This Flamingo is OK, not a great bike in many ways, but in some ways a good bike for the price. My next bike will be a Brompton titanium 1-speed.

BTW, a mechanic in Hanoi changed the wheel fastener (see enclosed photos). Time will tell if it works. Looks just like long nut to me. I asked for a secure solution such as Anklework kindly detailed in a reply above. But, alas - the shop was unable or unwilling to do such a task.

Notice the corrosion after only two months in southeast Asia .
