Serial 1's flagship is this Rush CTY Speed e-bike.

Serial 1 is a new e-bike brand spun off from Harley-Davidson. As you can see, graphics on the bike still call out this association.

The Rush CTY Speed is a Class 3 e-bike, meaning it offers electric pedal assist up to 28 mph. Its motor delivers 66 pound-feet of torque.

The Rush CTY Speed has a glove box designed for the Abus Bordo family of security locks. It also fits snacks.

The Enviolo CVT hub is transparent when riding, and it definitely sets the rider up for optimum pedaling.

The Rush CTY Speed is a very comfortable ride. It's offered in four frame sizes for optimum rider geometry.

The display screen looks really nice. This is the red boost mode, and I really enjoy the colors that accompany each ride mode.

The 706-wH battery fits nicely in the frame. It can also be removed for charging or replacement.

I really like the muscular frame design, and the Gloss Iris Silver Lead Grey color of this color looks sleek.

The Serial 1 Mosh CTY is more centered around urban fun than commuting.

The checkerboard details scattered around this bike's frame remind me of Vans shoes. You can also get this bike in two-tone matte and gloss black if this playful twist isn't your thing -- the checkerboard motif is way more discreet in the latter color scheme.

The Serial 1's badge lights up. Way cool!

All Serial 1 e-bikes have tail lights integrated into the frame. They brighten automatically when you start to slow down.

The Mosh CTY doesn't have a display screen like other Serial 1 Bikes. I like this because it's discreet.

The Serial 1 e-bikes are driven by maintenance-free Gates carbon-fiber belts.
