The Motobecane Mobylette Tricycle: A Utilitarian Evolution

The Motobecane Mobylette, a classic French moped that gained popularity in the mid-20th century, has long been admired for its simplicity and reliability. While originally designed as a two-wheeled vehicle, enthusiasts and utility-minded individuals have found ways to transform these iconic mopeds into three-wheeled wonders. This article explores the fascinating world of Motobecane Mobylette tricycle conversions, focusing on aftermarket modifications that cater to users seeking a more utilitarian version of this beloved vehicle. We'll delve into the history, conversion process, applications, and challenges of creating these unique three-wheeled Mobylettes.

A Brief History of Motobecane Mobylette

The Motobecane Mobylette first appeared in 1949, quickly becoming one of the most popular mopeds in France and beyond. Manufactured by Motobecane, later known as MBK after its acquisition by Yamaha, the Mobylette was renowned for its reliability and ease of use. The most iconic model, the AV42, featured a rigid frame with a rigid fork and bicycle-style caliper front brake.

Over the years, various models were produced, including the 50V, which introduced a variator for improved performance. The Mobylette's simple design and widespread availability made it an ideal candidate for modifications and customizations. While the original production focused on two-wheeled mopeds, the versatility of the Mobylette's frame and engine would later inspire enthusiasts to explore three-wheeled configurations for increased stability and utility.

The Concept of Tricycle Conversions

Tricycle conversions for mopeds and motorcycles have been a niche but persistent trend in the world of two-wheeled vehicles. The primary motivation behind such modifications is to enhance stability and increase carrying capacity, transforming a personal transportation device into a more utilitarian vehicle.

In the context of the Motobecane Mobylette, tricycle conversions typically involve modifying the rear end of the moped to accommodate an additional wheel. This modification can be achieved through various methods, such as:

1. Custom axle and wheel assembly: Fabricating or sourcing a specialized rear axle that can support two wheels instead of one.

2. Frame modifications: Reinforcing and altering the existing frame to handle the additional weight and stress of the third wheel.

3. Suspension adaptations: Integrating new suspension components to ensure a smooth ride with the altered weight distribution.

These conversions often require a combination of mechanical skill, creativity, and an understanding of the Mobylette's original design. While not officially supported by the manufacturer, these aftermarket modifications have given rise to a subculture of Mobylette enthusiasts who appreciate the unique blend of vintage charm and practical functionality offered by tricycle configurations.

Aftermarket Tricycle Modifications for Mobylette

While specific aftermarket kits for converting Motobecane Mobylettes into tricycles are not widely available, enthusiasts and skilled mechanics have developed custom solutions to achieve this transformation. The process of modifying a Mobylette into a tricycle typically involves several key steps and considerations:

1. Rear Frame Modification: The most crucial aspect of the conversion is altering the rear frame to accommodate two wheels instead of one. This often requires cutting and welding to extend the frame and create mounting points for the new axle.

2. Axle and Wheel Assembly: A custom axle must be fabricated or sourced to support two wheels. This may involve using components from other vehicles or creating a bespoke solution. The wheels themselves can be sourced from other mopeds, bicycles, or small-wheeled vehicles, depending on the desired aesthetics and functionality.

3. Drivetrain Adaptation: The original chain drive system needs to be modified to power the new rear axle. This might involve using a differential to allow for turning, or a solid axle for simplicity.

4. Suspension: Depending on the intended use, builders may choose to incorporate suspension elements to improve ride quality. This could range from simple spring systems to more complex shock absorber setups.

5. Braking System: The original braking system must be adapted to work effectively with three wheels. This often involves adding brake components to the new rear wheels and adjusting the brake linkages.

6. Load Carrying Modifications: To enhance the utilitarian aspect, many builders add a cargo area between or behind the rear wheels. This can range from a simple flat platform to more elaborate boxes or specialized carriers.

7. Performance Upgrades: Some enthusiasts take the opportunity to upgrade the Mobylette's performance during the conversion. This might include engine modifications, such as replacing the stock carburetor with a Dellorto 15/15 SHA, or adding a shorty intake to improve airflow.

It's important to note that these modifications require significant mechanical skill and should only be undertaken by those with experience in vehicle customization. Additionally, builders should be aware of local regulations regarding vehicle modifications to ensure their tricycle Mobylette remains street-legal.

Utilitarian Applications of Mobylette Tricycles

The conversion of Motobecane Mobylettes into tricycles significantly expands their utility, making them suitable for a variety of practical applications:

1. Local Deliveries: The added stability and cargo capacity make Mobylette tricycles ideal for small-scale delivery services in urban areas. They can be used by local businesses for food delivery, courier services, or transporting light goods.

2. Mobile Vending: Entrepreneurs have utilized these conversions to create mobile vending units for selling various products, from ice cream to crafts, especially in tourist areas or during events.

3. Urban Gardening: The cargo space can be adapted to carry gardening tools, plants, and supplies, making these tricycles useful for urban gardeners or landscaping businesses operating in tight city spaces.

4. Maintenance and Repair Services: For handymen or repair technicians, a Mobylette tricycle can serve as a compact, maneuverable vehicle to carry tools and spare parts to job sites.

5. Personal Transportation for Those with Limited Mobility: The added stability of three wheels makes these conversions an attractive option for individuals who may have balance issues but still want the freedom of personal transportation.

6. Eco-Friendly Alternative: In an era of increasing environmental awareness, these tricycles offer a low-emission alternative for short-distance transportation and light hauling tasks in urban environments.

The versatility of Mobylette tricycle conversions allows for creative adaptations to suit various needs, making them a unique and practical solution for those seeking a blend of vintage charm and modern utility.

Challenges and Considerations in Tricycle Conversions

While converting a Motobecane Mobylette into a tricycle can yield a unique and practical vehicle, the process comes with its own set of challenges and considerations:

1. Engineering Complexity: Transforming a two-wheeled vehicle into a stable three-wheeler requires careful engineering. Builders must consider weight distribution, turning radius, and overall balance to ensure safe operation.

2. Legal Compliance: Depending on the jurisdiction, heavily modified vehicles may face regulatory hurdles. Builders need to research local laws regarding vehicle modifications and registration requirements for three-wheeled vehicles.

3. Performance Impact: Adding weight and changing the vehicle's dynamics can affect the Mobylette's performance. The original engine may struggle with the additional load, potentially requiring upgrades or modifications.

4. Maintenance and Repairs: Custom-built tricycles may require specialized maintenance. Finding replacement parts or mechanics familiar with such modifications can be challenging.

5. Cost Considerations: The expenses involved in a quality conversion can be significant, potentially exceeding the value of the original moped.

6. Preservation vs. Modification: For collectors, there's a balance to strike between preserving the Mobylette's original character and enhancing its utility.

7. Skill Requirements: Successful conversions demand a high level of mechanical skill and fabrication ability, which may be beyond the capabilities of many enthusiasts.

Despite these challenges, many find the process of converting a Mobylette into a tricycle to be a rewarding project that results in a truly unique and functional vehicle.
