Mellowcabs are three-wheeled electric minicabs that are designed to provide an efficient on-demand taxi service in urban areas. They are eco-friendly with zero carbon emissions as they use a solar panel that produces up to 35% of the cab’s power and a battery to complement the cab’s needs. They are aimed to provide micro transport within a three miles radius. A single Mellowcab can provide over 120 km of transport per day. A mobile app connects the commuters and the cabs and payment can be made via the app. A promotional video is available here.

Manufacturer Specified Performance Parameters
Mellowcabs aims to provide low-cost and eco-friendly transport.
Vetted Performance Status
Unknown. Mellowcabs has however measured product performance through several trials in the field.
Towards improved safety, the MellowCab team has developed ultra-rigid roll cage, safety belts, and proximity sensors for the vehicles. Passengers are able to use lockable baggage areas underneath the seat to keep property safe. Drivers, after every shift, inspect the vehicle and complete a fault report. Maintenance is done on a scheduled basis. To ensure passenger safety, the cabs are monitored and tracked using a real-time GPS. Driving staff must complete an in-house training program, possess both a valid South Africa motorcycle license and a professional-driving permit and submit random alcohol and drug tests. Passengers can also submit their feedback via on-board tablet.
