(2) big chaining is more suitable for city bike, road bike and foldable bike which can help you enjoy faster speed . However , now you are converting a bike to an ebike with motor, the size of chainring won't influence much because there is enough power for you to ride. When you install a mid motor on your bike , the bigger the chainring is , the faster the speed wil be. And please note that the chainring is more compatible with a bike ≤9 speed.
