Hello, there!

I'm not sure if this is the correct location for this question or if it was answered somewhere I couldn't find previously, so let me know.

I just bought a Bridgestone 100 Mixte to bop around town and to ride to school next year, nothing fancy. I found it on craigslist and am happy with her condition.

However, this little bike has stem shifters.

I haven't had much time to play around with it yet but I know I looked silly jolting around today. I feel like I'm trying to learn to drive stick shift again!

Does anyone have a simple explanation/tips to help me get the hang of this?

Much appreciated.
