That's OK as long as the tire does not rub on the frame. Since you are only shifting one side of the wheel adjusting this way can put the wheel off center in the frame. At this point you may be able to squeeze the chain and get a little slack in the chain.With the training wheel off loosen the nut that holds the wheel on.Remove the nut on the chain side of the wheel that holds the training wheel.There is the easier way and the slightly harder way to adjust chain tension. (When I started writing this I thought it would be a few steps - but it kept getting longer.) If the crank is stiff you'll need to loosen the crank bearings. If the chain tension is OK slip the chain off the chain ring and feel how easy the crank is to move. If it does not you'll need to loosen the bearings on the hub. With the brake disengaged the wheel should spin freely. You may be able to loosen the chain a little and feel an improvement immediately. If the chain is tight it will be hard to pedal. You are right to ask about chain tension.This will give you a baseline to know if you've made improvements as you adjust things. My guess is that there is something that can be adjusted to make things better.įlip the bike over so it's sitting on it's seat and handlebars. From the factory it seems like everything is always too tight. Children's bikes are usually designed with easy gearing appropriate to children.Īs Chris H said - they are not usually assembled by people who care that a bike is assembled correctly.
