Looking to buy a bike for my daughter. She won’t use it much, just like her other bikes, but in those rare instances she does want to ride I want to make sure there is a bike available. Most of the riding would be either paved trails or hike/bike trails, nothing aggressive. She’s a teen, about 5’5”, thinking of an entry level hybrid. Noticed the entry level bikes mostly have grip shifters. I have never used grip shifters on a regular basis and because of that I am biased against them.

I was wondering if grip shifters work fairly well. Should I upgrade to a bike with thumb shifters?

Thinking of something like this:

Schwinn Sierra 2 Bike

Information appreciated.
