Mass produced Hub motors out of China have made a huge impact on the electric bike market. There are a large number of E-bikes available on the market today because of the invention of the electric hub motor. Because of hub motors, E-bike manufacturers are able to use just about any bicycle frame to turn it into an electric bike. For better or worse, almost any company can choose to be an e-bike manufacturer thanks to the simplicity of hub motors.
You will find hub motor bikes of all shapes and sizes…cargo E-bikes, sand E-bikes, 3-wheeled E-bikes, pedicab E-bikes, folding E-bikes etc. Because hub motors were made in mass quantities, they are also very affordable and reliable. A hub powered bike may be the best solution for a commuter E-bike. Whether you’re building or buying an E-bike, “to hub, or not to hub” should be the question.
Although hub motored bikes are convenient and readily available, the most exciting electric bikes on the planet are not hub motor bikes. Look at the 10 most expensive e-bike list for some very good examples of mid-drive bikes…with a few overly priced hub bikes thrown in. Because of their simplicity, it’s just plain wrong when manufacturers charge big bucks for hub motor bikes. Remember, anyone can build a hub motor bike…even you in your very own garage.
