rickshaw - Google Search
That is what comes up when you search for rickshaw on EValbum.com
Only a SepEx golf cart motor is going to allow regen breaking and for stop and go traffic that would be worth while, with heavy traffic you are also going to want to force cool the motor or you will burn it up.
A permanent magnet motor is also going to allow regen breaking but is going to be less powerful for the size and weight.
