Speed and Power

One of the most impressive features of the Rattan LF Ultra is its ability to reach speeds up to 32 miles per hour. This is facilitated by a 48-volt 1000-watt brushless rear hub motor, features a peak power rating of 1,800 watts and 100 Neuton meters of torque. This power enables swift acceleration, making it suitable for fast-paced delivery situations.

Pedal Assist and Throttle Control

The LF Ultra is designed to offer five distinct levels of pedal assist, providing versatility for different riding situations. Riders have the option of using the half-twist throttle for a more hands-off approach or engaging in pedal cycling for a workout experience. The bike’s cadence sensor enhances efficiency by determining the best assist level for your pedaling speed.

Real-World Testing

During testing, the bike was initially put through an off-road performance evaluation, allowing for a better understanding of its suspension capabilities. The reviews indicated that even when traversing bumpy terrains, the spring-loaded front forks and suspension seat post worked together effectively, providing much-needed support during rugged rides.

Size and Weight

Weighing 86 pounds and equipped with a maximum payload capacity of 300 pounds, the LF Ultra manages weight effectively, which is crucial for delivery scenarios. Its compact folding design means it can be stored away easily or transported in a vehicle, making it perfect for urban use.

Specifications:

• Dimensions when folded: 39 inches long, 32 inches tall, and 18 inches wide.
• Rider height range: Suitable for individuals from 5’3” to 6’4”.

Aesthetic Design

The LF Ultra comes in a vibrant red color, making it visually appealing. Although it has only one color option, the striking look is complemented by practical components, including durable, weatherproof features.

Frame Composition

Constructed with a sturdy frame, the bike hosts mag wheels and all-terrain tires (CST 20×4 inches) that offer puncture resistance. The combination of these tires and the bike’s geometry enhances traction and stability, essential for riders dealing with variable weather conditions.

Seating Configuration

Riders will appreciate the comfortable padded seat and adjustable suspension seat post, which provides superior shock absorption. The seat position is customizable to accommodate varying rider heights and preferences.

Handlebars and Controls

The bike has a user-friendly control interface featuring a full-color display that showcases battery percentage, speed, and other operational data. The design promotes intuitive riding, allowing riders to easily adjust the pedal assist level and monitor performance without distraction.

Battery Capacity

The Rattan LF Ultra features an extensive 48V, 40.5 amp-hour battery, offering an impressive total capacity of 1,944 watt-hours. This size should allow riders to cover substantial distances before needing to recharge.

Charging

Charging is quick, with a 4.5-hour full charge time. The design allows for convenient recharge either while on the bike or by removing the battery for external charging. Safety measures include a two-key system that locks the battery in place and disengages the bike’s power.

Brake Performance

The bike is equipped with cable-actuated hydraulic brakes featuring 180mm rotors, providing adequate stopping power. However, during tests, it was noted that the braking distance could be longer than expected, raising concerns for potential safety hazards in emergency situations. Proper adjustments might be necessary to enhance the brake responsiveness.

Weatherproofing and Durability

With an IP6 rating, the battery can manage exposure to high-pressure water streams, ensuring reliability in adverse conditions. Additionally, the bike features plastic fenders and other components designed to withstand the elements, which works well for delivery individuals facing various weather situations.
