We're going to be here for 1 month. The bikes are in decent condition, although I did have to fix my bike today, as we drove that costal road between Hue and Da Nang that Top Gear did and it was pure heaven, almost no traffic, good pavement and as scenic as anything in Switzerland/France/Italy. I did kill my rear wheel bearing, which made the rear wheel wobbly and destroyed the rear sprocket.
Keep in mind that this is a 125cc bike (not scooter) that is carrying about 400lbs (me and the backpacks being the majority of the weight) doing some really tight cornering.
We had lunch while a local mechanic fixed it. He was done before we finished lunch. Total cost of new rear sprocket, new rear bearings and labour...... $10!!!!!!
Bike is like new again, and ready to do the 900km to Saigon.
After riding in Hanoi, I'm used to anything that can happen anywhere. There is a method to the madness though and I've got a hang of it now.
