Summary of CERO One E-Bike Review

the CERO One, a fabulous e-bike, guided by the founder, Kiyoshi Iwai. This 2021 model is a nod to the classic Japanese “mama chari” bike, designed for practicality and utility. One of its standout features is the smaller front wheel (20 inches) compared to the rear (26 inches), inspired by British mail bikes for a lower center of gravity and easier cargo handling. The bike boasts several accessories, including a large basket, child seat, and a frame lock by ABUS for added security.

CERO One’s story began in 2015, rooted in a vision to bring eco-friendly transportation to the U.S., inspired by the Japanese mama chari. Over the years, it’s evolved significantly, particularly with its upgrade from the older Shimano Steps motor to the new E6100 motor, which offers more power and torque while being lighter and more compact. The bike’s design is all about efficiency and reliability, featuring a Gates Carbon Belt Drive and an internally geared Shimano Nexus 5E hub, replacing the older derailleur system for a cleaner, quieter ride.

The CERO One is built for utility with thoughtful design elements. Its frame is reinforced with gussets and support arms, and it has a telescoping stem for easy storage. The bike is equipped with a variety of mounts and accessories, including custom fenders, a double-leg kickstand, and a robust front rack integrated into the frame for better load stability. Safety features include reflective stickers, a built-in headlight, and hydraulic disc brakes for excellent stopping power.

One of the most impressive aspects of the CERO One is its range, capable of up to 105 miles on a single charge, thanks to its 504 watt-hour battery. Despite its robust build, the bike weighs a manageable 58.2 pounds. The battery is designed for easy removal and charging, with a compact, lightweight charger that, while slower, is more convenient to carry.

The Shimano drive system is quiet and efficient, offering a smooth ride with its advanced pedal cadence, torque sensors, and rear-wheel speed measurements. The display panel is sleek, removable, and offers detailed ride information, including range estimates and speed, with customizable settings for a personalized experience.

In summary, the CERO One is a well-thought-out e-bike that balances practicality with modern tech upgrades, making it an excellent choice for urban commuters and those who need a reliable, versatile cargo bike. With a price tag of $3,799, it’s a reasonable investment for its quality and features, backed by a solid warranty and support from the company.
