Physical Specifications of Lito (7M) Electric Bus

Compact Build

One of the Lito (7M)’s defining features is its small build, making it particularly well-suited for navigating the often narrow and congested streets found in many urban areas.

Dimensions

The Lito (7M) measures 6970 mm in length, 2200 mm in width, and 3020 mm in height. These dimensions strike a balance between compactness and passenger capacity.

Length (6970 mm)

At just under 7 meters long, the Lito (7M) is considerably shorter than many standard city buses, which can range from 10 to 14 meters. This reduced length offers several advantages:

• Improved maneuverability in tight urban spaces
• Easier navigation through narrow streets and sharp turns
• Reduced impact on traffic flow, particularly important in congested city centers

Width (2200 mm)

The width of 2200 mm (2.2 meters) is relatively narrow for a bus, further enhancing its ability to navigate through tight spaces. This width:

• Allows for easier passage through narrow lanes and streets
• Reduces the bus’s footprint at stops and stations
• Potentially allows for the creation of dedicated bus lanes in areas where wider vehicles might not fit

Height (3020 mm)

At 3020 mm (just over 3 meters) tall, the Lito (7M) maintains a standard height for urban buses. This height:

• Provides sufficient headroom for standing passengers
• Allows for clearance under most urban bridges and overpasses
• Maintains stability while offering a good vantage point for passengers

High Capacity and Larger Inner Space of Lito (7M) Electric Bus

Despite its compact external dimensions, the Lito (7M) is designed to maximize internal space and passenger capacity.

Seating Capacity

The bus offers seating for 21 passengers plus the driver (21+D). This seating capacity is impressive given the vehicle’s compact size and speaks to the efficient use of interior space.

Flexible Seating Arrangements

The “+D” notation suggests flexibility in the seating arrangement. This could indicate:

• Options for different seating configurations to suit various route needs
• Potential for additional folding or tip-up seats to be added during peak hours
• Space for wheelchair users or passengers with strollers, enhancing accessibility

Optimized Interior Layout

The emphasis on a “much larger inner space” indicates that significant thought has gone into maximizing the usable area within the bus. This could involve:

• Clever placement of mechanical components to free up passenger space
• Use of lightweight materials to reduce overall weight and increase passenger capacity
• Strategic positioning of seats, handrails, and other fixtures to optimize flow and comfort

Standing Room

While the seating capacity is specified, the total passenger capacity (including standing room) is likely to be significantly higher. The design likely incorporates ample standing room with well-placed handrails and support structures to accommodate peak hour crowds safely and comfortably.

Floor Height of Lito (7M) Electric Bus

The Lito (7M) features a floor height of 900 mm, which plays a crucial role in accessibility and operational efficiency.

Accessibility Considerations

A floor height of 900 mm (0.9 meters) represents a middle ground between high-floor and low-floor bus designs. This height:

• Is low enough to facilitate easier boarding and alighting for many passengers, including the elderly and those with mild mobility impairments
• May require a single step or a short ramp for entry, which is more manageable than the multiple steps found in high-floor buses
• Could potentially be combined with a kneeling function to further reduce the step height at stops

Operational Advantages

The 900 mm floor height also offers several operational benefits:

• Provides sufficient ground clearance for navigating speed bumps and uneven road surfaces
• Allows for efficient packaging of battery and drivetrain components beneath the floor, maximizing interior space
• Offers a good compromise between accessibility and the cost-effectiveness of the overall vehicle design

Potential for Level Boarding

Depending on the infrastructure at bus stops, the 900 mm floor height could allow for near-level boarding at specially designed stations. This would significantly enhance accessibility and reduce dwell times at stops, improving overall service efficiency.
