Electric bicycle is too costly for Indian cycle market. Regular users of bicycle in India are low income people and school students mostly. For these segment cycle is low cost transport machine. Price of an electric bicycle/kit is not affordable to these regular and today commuters.
Cycle means no maintenance. This is our mindset about cycles mostly. Battery powered bicycle require maintenance. This will raise complaints retail shops, which is new to retail shop owners. Support to cycle after sales never exists.

Street cycle mechanics have to upgrade to electrician. Otherwise they could not manage the issues in electric bicycle.
Above all, cost is the major obstacle to get an entry in to electric cycle.
