The Micro - Mobile EV follows a sustainable path towards innovating & incorporating the convenience of compact MMVs & efficient performance of traditional EV scooters. It creates additional revenue streams by following specially curated decentralised manufacturing processes that benefit the small business communities of ward 110 in Bengaluru - India.
Type: Pre Thesis - Semester 07
Time: 04 Months
Team: Individual Project
Ward 110, a lively commercial marketplace in the heart of Bengaluru houses a variety of business such as manufacturers, import/exporters, repair centres and spare part suppliers. Inefficiency in commute of solo travellers working there has worsened traffic conditions. Cities are getting heavily populated unable to house the sheer mass of people. Mobility for solo travellers has hardly seen advancement, with saturated public transports, last mile connectivity is scarce, less available and not cost effective. Due to this most market places in ward 110 lack accessibility affecting employability and eventually affecting businesses.
The brief was to bring an intervention into the ward 110 business community helping users to navigate through this vast stretch of market intern boosting the wards efficiency. Its creation should benefit business establishments small & big and also create an impact outside the designated marketplace.
To design & develop a product and system that benefits the ward 110 Bengaluru-India business community and mobility in and around Bengaluru city.
Opportunity Areas
I have was always been passionate about Urban city planning, Mobility Solutions & Transportation Design. This project allowed me to integrate all my interests. Living in Bengaluru for more than four years, I personally along with many university peers have experienced inefficient mobility. Using a wide range of transports to reach a destination not very far away consumes lot of time but is an economic option. Overtime, peoples approach towards last mile commute has changed giving more importance to time over expense. The aim was to create a middle ground product that combined specific attributes from various mobility solutions beneficial for individuals who were in need of a better last mile connectivity option for moderately long distances.
The final aim of the product does benefit the ward 110 business communities meeting the brief perfectly, but it also creates an impact on the entire city of Bengaluru redefining last mile connectivity in a more practical sense.
Transport is cities cannot just cater to a small group of individuals. Millions of people commute every second, heavily populated cities in India such as Mumbai, Delhi & Bengaluru mainly rely on a variety of public transports to maintain flow of mobility. It does not solve the problem of last mile connectivity because it is not designed to, with every individual having a different destination, public transports cannot provide 100% connectivity. A large group of individuals opt for private transports since public transport is not always accessible.
This intervention would help those individuals commuting via personal transport on a daily basses over moderately long distances due to public transports being inaccessible, time consuming and crowded. It would save time and make travel more economically and environmentally sustainable. The product could be an inexpensive and quicker alternative to traditional vehicles such as scooters/bikes that can be purchased or rented.
Most micro mobile EVs have very little range and are not designed for comfort. This hybrid scooter, not in a mechanical sense but in design, Is comfortable to ride, has various configurations for longer distances, is durable, designed for Indian road conditions and most importantly is economically sound when it comes to manufacturing & serviceability. Although it might now follow a general mass production model, the aim was to design for technology and skillsets present in ward 110 only.
The project targets three United Nations Sustainable Development goals.
[09] INDUSTRY, INNOVATION & INFRASTRUCTURE
[11] SUSTAINABLE CITIES & COMMUNITIES
[12] RESPONSIBLE CONSUMPTION & PRODUCTION

Before proceeding with the final chassis fabrication, a 1:1 scale model of the EV was made by laser cutting 3mm foam-board to mimic the 3mm aluminium. The model was assembled and minor changes were noted. Basic circuits were setup to test the models accommodation abilities. The model also gave a clear understanding of the EV's assembly process, eliminating any difficulties I would have faced while fabricating the final prototype.
A rather minimalistic yet modern design for the front console. The wide front not only cuts through air but provides added protection the the users under body.
The front unit does more than just contribute to aerodynamics and safety, it is designed to house a secondary battery that supports regenerative braking increasing the bikes range by upto 60%.
A wide and long wheel base enables the user to comfortably stand with both feet side by side, in traditional MMVs the base being too narrow cause the user to have a rather uncomfortable feet placement. Grip extrusions enable large amounts of water to flow through the grooves preventing the user from slipping.
Built under a straight forward decentralised manufacturing system, the design describes its simplicity by form and assembly. Locally made, serviceability is inexpensive and widely availible.
Aero plates avoid wind vortexes created by the rotating rims. The small service panel on the aero plate helps inflate the tyre. LED Indicators increase side visibility of the product
10 Inch Pneumatic Tiers absorb road shocks providing a smoother ride. A high torque 24V 350 Watt hub motor powers the bike, an integrated drum break provides rear braking. With a set top speed of 15 kmph, it requires no registration under Indian Traffic laws, but with registration it can reach speeds of upto 25 mph.

The red plastic mounts attach directly to the chassis which hold all the side panels in place.
To test the product and manufacturing system, using the vendor list and research I was able to curate a 06 week personal fabrication process. The process was carried out by me individually in university workshop premises.
Final Finished Product
A fully Aluminium 6061 body prevents any king of corrosion, adds strength to the chassis and is extreamly lightweight. The aluminium helps keep the battery cool by dissipating the heat through the frame. Modularity in body panelling enables the user to only replace small portions of the panelling incase of damage. With a range of upto 25km on the primary battery with a single charge, it can extend its range to over 40km with the secondary battery housed in the front panel along with regenerative breaking.
A sleek front LED helps throw a wide light beam unto two meters away, since it is a city transport dedicated to fight traffic and deliver last mile connectivity, this lighting option sufficiently contributes to well lit city roads and does not deplete the battery capacity. Designed for easy assembly also means that it is designed for easy disassembly, the bike front module can be unscrewed using an 8mm allen key for easy storage indoors. An industrial looking product for a rather industrial manufacturing system.
The EV features an airplane switch for starting, provided the bike is unlocked my the user using the MMV app. A small display shows crucial data such as battery %, speed and the battery temperature. The lights operate using a daylight sensor located inside the headlight but also have a dedicated button on the console. A carabiner on the console helps the user to hang lightweight items such as a small bag or a helmet.
Does what it's made for, the Micro Mobile EV is a perfect blend of power and stability. It can reach a speed of 15 kmph in less than four seconds making it perfect to accelerate in traffic conditions. The wide base not only houses a bigger battery but also helps the a comfortable stance on the EV. The pneumatic tyres absorb majority of the road vibrations making the ride smoother.
Testing the prototype via 3 users on different road conditions across varied speeds. Documenting its performance via interviews helped understand its strengths and weaknesses.
The Project was featured in the Bengaluru Design festival, which is the world's largest annual design fest for designers to meet, discuss and showcase new facets of the design.
I was able to interact with design professionals, industrial design students & prospective designers from various parts of the country.
