Summary of Serial 1 RUSH/CTY Speed
The Serial 1 RUSH/CTY Speed, launched by Harley-Davidson’s spin-off company Serial 1, is an impressive Class 3 e-bike designed for urban commuters. Since its introduction in 2020 and release in 2021, this bike has stood out for its higher capacity 706-watt-hour battery pack compared to the standard model’s 529-watt-hour battery. This upgrade, along with its robust build and impressive features, makes it a popular choice among e-bike enthusiasts.
One of the most striking features of the RUSH/CTY Speed is its suitability as a commuting platform. Equipped with built-in racks, integrated fenders, and lights, it’s designed to handle daily commutes with ease. The bike boasts an Enviolo automatic, continuously variable transmission hub, and a Gates Carbon belt drive system, ensuring a clean, low-maintenance experience without the hassle of derailleurs. However, these high-end features come at a premium price, but the investment is justified by the bike’s performance and convenience.
The bike’s frame is available in four sizes and two colors, featuring a metallic blue option that highlights its modern design. The angled top tube lowers the stand-over height, making it accessible for a wide range of riders. Despite its aggressive stem and low-rise bar, the bike offers a surprisingly comfortable and upright riding position. With ergonomic grips and larger tires, it’s built for comfort, although the lack of a suspension fork means it might feel a bit stiffer on rough terrain. Weighing in at about 59 pounds with all accessories, it balances weight and stability well.
Innovative features like a locking glovebox compartment above the battery pack, Schwalbe Super Moto-X tires, and robust hydraulic disc brakes enhance the bike’s practicality and safety. The tires, at 27.5 x 2.8 inches, provide excellent contact and a softer ride, while the TRP hydraulic disc brakes with 203mm rotors offer superior stopping power. Additional features include an adjustable kickstand, Wellgo BMX pedals, and a proprietary frame design that simplifies belt installation.
The bike’s electronics are equally impressive. With an IP65 water and dust resistance rating, the bike is built to withstand various environmental conditions. Charging is convenient, with the port located near the bottom bracket, and the battery is easily removable for off-bike charging. The 42V 4A charger is faster than typical e-bike chargers, reducing downtime.
The cockpit features a flick bell and a clear, easy-to-read Brose display, which is transflective for good visibility in bright light. The bike supports walk mode and has four levels of pedal assist: Eco, Tour, Sport, and Boost. The integrated lights, including a 900-lumen headlight and brake-activated rear lights, enhance visibility and safety.
The Serial 1 app offers additional functionality, including turn-by-turn navigation, ride tracking, and security features like remote locking and location tracking. This level of integration, along with the bike’s performance and build quality, makes the RUSH/CTY Speed a top contender in the e-bike market.
