I'm still pretty new to riding a bike, so please bear with my lack of technical knowledge (but with the expertise here I'm learning very quickly).
I recently purchased a single speed bike (just a super cheap one) and I want a smaller chainring. The bike rides fine without any cargo, but I use it to run errands with my son (so once I get his 30 lbs and groceries it's a very difficult ride). Can I change out the chainring for a smaller one? Where would I find the parts I need?
Additionally, this bike has coaster breaks. I do like them, but is it possible to install a front cable break as a fail-safe (I worry what will happen if my chain breaks or if I need to break for an emergency)?
Thanks for the help!
