The Interceptor, Boomerang, and City Commuter are all best-selling models that have more similarities than differences. None is necessarily better than any other, it’s a matter of preference.
The primary difference is the frame.
The Interceptor uses a beach cruiser frame that’s designed to be comfortable. It features beach cruiser geometry that promotes a very upright riding position and allows you to put both feet flat on the ground when you stop.
The Boomerang is the most accessible electric bike on Earth. It features an ultra-low 9” step thru frame. It’s also designed for comfort with an upright riding position somewhere between the Interceptor and City Commuter.
The City Commuter uses a more traditional frame that’s well balanced for all-around use. It’s a classic style that is quite comfortable with a relatively upright riding posture.
The next difference is the handlebars, but keep in mind that all three models use standard sized bicycle stems and handlebars that can easily be changed.
The Interceptor uses wide, swept back bars that really allow you to sit straight up and relax your upper body. Because they are quite wide, they can take a little time to get used to, and it’s common for people to have mixed feelings at first and learn to love them in a very short period of time.
The City Commuter and Boomerang models use traditional city-style handlebars that many people find to be very natural and familiar. The quick release adjustable handlebar stem allows you to easily dial everything in just right for you at any particular moment. This is great for multiple riders sharing a bike or if you plan to change your riding style and position frequently.
The final difference is the fenders are optional for the Interceptor and Boomerang models, and they are included on the City Commuter.
