A bike chain cover is primarily designed for children. It is a method of ensuring that the bike’s chain doesn’t cause any issues for the rider. The major drawback of a chain cover is that you can’t use a cover in tandem with a multi-geared bicycle. The changing chain angle makes a guard all but useless.
So on an average mountain bike, a bike chain cover is not a very practical idea. For children’s bikes however, they are an excellent idea. A child is fully engaged just learning to balance and steer on two wheels. They don’t have any concentration to spare for angling their leg just right. Having a leg caught in your gear can result in a nasty spill. The kind of accident that makes a kid foreswear biking forever.
For kids, a bike chain cover isn’t just a good idea; it’s on the same level as a helmet for being mandatory. A few decades ago, helmets weren’t mandatory for kids, and in a strictly legal sense, they still aren’t. But a parent who puts their child on a bicycle without a helmet is asking for a terrible accident. Helmets and chain covers are both great safety ideas that will help your child enjoy riding their bicycle.
