Now, the real test lies in how it performs on the road – a journey that promises to be as smooth as the Rosemont LS itself.
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:
- Eco mode (Pas1): 12.6 mph – a leisurely pace, ideal for relaxed commuting.
- Tour mode (Pas2): 14 mph – a step up in speed, providing a bit more engagement.
- Sport mode (Pas3): 17 mph – a sweet spot for a comfortable and efficient ride.
- Turbo mode (Pas4): 18 mph – a faster pace, suitable for open paths.
- Boost mode (Pas5): 20 mph – reaching the class two top speed, offering that extra boost when needed.
However, during the Boost mode, there was a mention of ghost pedaling, where the pedal felt disconnected from power delivery. The suggestion to adjust the gearing, perhaps with a 48-tooth chainring or an 11-tooth top gear cog, could potentially address this issue, providing a more robust and seamless pedaling experience.
The torque sensor’s ability to capture pedal intensity and adjust power output accordingly adds a layer of sophistication to the riding experience. It’s particularly noteworthy that the motor’s efficiency, coupled with the torque sensor, contributes to energy frugality, extending the bike’s range by consuming less battery power.
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.
The star of the show is undoubtedly the 350-watt mid-drive motor with a torque sensor. The motor engages with a balanced distribution of power, responding promptly to the rider’s pedaling intensity. 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.
The bike’s performance on hills, as demonstrated in the throttle-only and maximum Pedal Assist (Pas5) tests, showcases its capabilities. The throttle-only test on a steep hill, referred to as “hell hole,” yielded impressive results, with the bike easily conquering the climb at an average speed of 11.7 miles per hour. The mid-drive motor, designed for city riding, proved its worth in delivering substantial power for hill climbs.
However, in the maximum Pas test, a slight lag in torque sensor engagement during gear shifts was noted, leading to a slower-than-expected time. Despite this, the bike demonstrated its ability to handle hill climbs with ease, further emphasizing its suitability for urban commuting.
The Electric Bike Report brake test puts e-bikes through a rigorous assessment, ensuring their braking performance meets safety standards. In the case of the iGo Discovery Rosemont LS, the test involves the rider pedaling the bike up to 20 miles per hour before engaging the brakes to bring it to a complete stop. This process is repeated multiple times, with the average stopping distance calculated for a comprehensive evaluation.
In the case of the Rosemont LS, the average stopping distance was measured at 25 feet and one inch. While this result may fall a bit short of expectations by a couple of feet, it’s worth noting that the bike is equipped with a Tektro hydraulic brake system, a setup that has been tested on similar style bikes.
Despite the slight deviation from expectations, the real-world performance of the brakes is commendable. The rider, after logging over 120 miles in test rides, found the braking experience to be smooth and consistent.
