Boda boda are bicycle & motorcycle taxis commonly found in East Africa. While motorcycle taxis like boda bodas are present throughout Africa and beyond, the term boda boda is specific to East Africa. In Kenya, they are more frequently called piki-pikis. Their ubiquitous presence in East African cities is the result of a number of factors including an increasing demand for public transit, the ability to purchase motorcycles on credit, and an influx of cheap imports from Indian manufacturers like Bajaj. In the countries where they are present, boda boda can provide vital job opportunities for entrepreneurial young men who lack skills lifting their incomes and brightening their lives while at the same time resulting in an increase in road accidents and unnecessary deaths.
A competing suggestion is that the boda boda had an apocryphal ability to transport people across a border without a need to complete the paperwork using a motor vehicle would necessitate; i.e. from border to border. 
In 2013, one source claims 300,000 were operating in Kampala, Uganda. Data from the Kampala Capital City Authority show 120,000 registered motorcycles in the city around the same time although the number of boda boda could be higher as some are unregistered according to a representative of the Kampala Boda-boda Riders Association. The same source indicated in 2015 that around 40,000 were operating in central Kampala. Another knowledgeable source suggested in 2015 that the true figure is closer to double that number.
Across Uganda riding boda bodas has become a substantial source of income for many youths, providing livelihood to thousands of families in the country. In Kampala, the business has attracted tour and travel investors with one company 'Uganda Adventure Safaris and Boda Boda Tours' providing city maneuver as one of their exciting tour packages for many visitors and tourists in Kampala.
An Uber-style e-hailing mobile app for motorcycle taxis, SafeBoda was founded in late 2014, and, as of 2015, restricted its operations to Kampala, Uganda. It provides training and helmets to drivers who access fares through its app. The smartphones carried by drivers can collect braking data allowing the firm to rank operators' safety, and a routing system that relies more on landmarks than maps helps ensure only those who possess thorough local knowledge will attempt to pick up a potential fare. A similar app called SafeMotos has been launched in Kigali, Rwanda.
In Uganda, they are known as boda bodas...
The word boda boda has a very interesting etymology. It turns out that in the early days of transport between kenya and Uganda, crossings between the two countries were known as going 'border to border' and one of the modern means of transport became a modified new word.
