The traffic in HCMC is considered as a "crazy" one in Vietnam accompanied with other big cities.
Streets are narrow but the number of bikes as well as other transportation means is huge so it's not safe for tourists to ride on bike around HCMC expect those who are confident in their "riding tech"
Therefore to be "safe" i recommend u to take a cyclo,it's really cheap
Cyclo or pedi-cab is probably the cheapest way to get around observe the city of Saigon (HCMC). Although, in certain areas of the city cyclos are restricted. There is an obvious hassle when using this form of transportation, that bargining. Make sure you work out a price with the driver before you get on...Cyclos usually wait around in groups, so if the bargining doesn't work out with one, there are still plenty to bargin with. I personally never used cyclos but my cousins who lives in Vietnam gave me some insight for this tip page.
In a city of Motorcycles and Bicycles this is Vietnam's answer to the taxi, The Cyclo. Unfortunately they are just as expensive as the cabs and not airconditioned. take one for the experience and then take cabs.
Cyclo is my preferred method of transport in Saigon, it is easy, cheap and relaxing.
Remeber that you shouldn't pay more than 10,000 Dong for a trip, and they will rip you off if they can.
Taxis are available as well.
By cyclo. This is a Vietnamese Rickshaw, and is a fun and very inexpensive way to explore the city. (see warnings and dangers above for a cautionary tip). Look how happy my friend Brad is looking through his Vietnamese phrase book while riding this cyclo (too bad he couldn't pronounce any of the phrases he learned).
Letting you drive around in a cyclo has many advantages:
it's safer than walking
it helps local people earn some money
you can film while being driven
Cyclos are a good way to see the city during the day. However, I'd avoid using them at night. Some cyclo drivers have been known to take you down dark alleys at night and mug you.
