iGo Discovery Rosemont LS: Motor and On the Road

The 350-watt mid-drive motor on the iGo Discovery Rosemont LS is a true standout, surprising riders with its powerful performance and immediate engagement. Unlike traditional cadence sensors, this bike employs a torque sensor, a smart move for managing power delivery. The torque sensor detects how hard you’re pedaling, ensuring a seamless integration of motor assistance and making the ride feel almost intuitive.

The motor, known as the iGo Drive, operates at 48 volts and features five pedal assist levels: Eco, Tour, Sport, Turbo, and Boost. Each level caters to different riding situations, allowing riders to customize their experience based on terrain and personal preference.

In a thorough speed and acceleration test, the bike showcased its versatility. Starting from pedaling with no motor assist, the Rosemont LS reached a comfortable speed of 9.9 miles per hour. Moving through the pedal assist levels, each mode offered a unique speed profile:

In everyday riding, the Sport mode emerged as a preferred choice, offering a constant and predictable speed while conserving battery energy. The rapid-fire trigger shifter made gear shifts easy and quick, adding to the overall user-friendly nature of the Rosemont LS.

When it comes to the overall ride quality of the iGo Discovery Rosemont LS, it seems to have nailed the balance between comfort, control, and performance. As a commuter bike, it adopts an upright posture, leaning slightly forward with fully extended arms and handlebars that have a slight rise. This setup provides a comfortable feel and a good sense of control, crucial for navigating through urban environments.

The handlebar width is just right, offering control without feeling too wide, ensuring a smooth ride through crowded spaces. While the stem is not adjustable, its stationary nature eliminates concerns about it loosening during rides. The seat, although standard, proves to be mostly comfortable for rides exceeding 20 miles, thanks to its quick-release mechanism for easy adjustments.

The suspension plays a vital role in the ride quality, with the RST Blaze Fork providing 80mm of wheel travel. This, combined with the 27.5 by 2.4-inch WTB Groove e tires, results in a smooth and controlled ride, absorbing bumps and rough road sections effectively. The tire tread design offers good traction and handling on dry concrete and asphalt, making it suitable for urban commuting. However, caution is advised on wet pavement, sand, ice, snow, and mud due to the tire tread.

This not only contributes to a more enjoyable ride but also enhances efficiency, as the motor delivers power consistently based on the rider’s needs.

The size of the bike caters to a broad range of riders, accommodating heights from 4 feet 8 inches to 6 feet 2 inches. The seat height range of 29.9 inches to 37.8 inches, coupled with the handlebar’s slight rise, ensures a comfortable fit for most riders. The non-adjustable stem may be a consideration for those accustomed to adjustable stems, but for many, it won’t be a drawback.
