I looked into it for the fun of it and found out that you can buy these kits for a standard bicycle for well under $1,000. Seems like the perfect vehicle for college students living in a college town, like my college experience at Humboldt State University.
I was quite intrigued when I finally saw one these bike with a engine kit mounted to it and made sure to take a lot of pictures so you guys could check it out too. Though it's nothing to do with Bajaj, it's pretty damn interesting.
