Bus travel around the city is very cheap but unbelievably crowded, so much so that you'll probably miss your stop because there's no way you'll be able to see out the window. A dilapidated trolley bus runs from near the National Stadium to Bhaktapur. Taxis are reasonably priced, but you'll probably have to negotiate the price in advance as drivers are unwilling to use the meter. Many private cars are happy to give you a taxi service, but they don't have meters at all. Auto-rickshaws cost about half as much as cabs, though once again, you'll have to negotiate a price.
Bicycle rickshaws are more expensive than cabs.
