Design and Fabrication of Hybrid Half Bike | Mechanical Project


In technological world the vehicle plays an important role but it’s also has its own faults such as creating pollution and emission. In order to overcome these problems we have to use alternate vehicles. There are several available sources and one of the solutions is Hybrid half bike. The word Hybrid means two or more amount of energy sources. In this project mechanical and electrical energy is used and also it is a hybrid of segway and half bike. In this type of bikes, frames are fabricated by complicated design and it is user friendly. The important specification of the bike is that by folding the bike it can be easily carried to any place and it is affordable for common man. Less number of linkages is used to fold the bike. This paper aims at evaluating the entire existing foldable half bike and proposing a compact foldable hybrid half bike by using three bar mechanism. It is fabricated with MS Plate to reduce the total weight of the bike. The fabricated bike can be considered as the hand luggage and proposed hybrid half bike is designed in such a way that it is foldable by providing fasteners at the joints. The design structure imparts stable hybrid half bike geometry. The vehicle is controlled by body balance.


A folding bicycle is a bicycle designed to fold into a compact form, facilitating transport and storage. When folded, the bikes can be more easily carried into buildings, on public transportation (facilitating mixed-mode commuting and bicycle commuting), and more easily stored in compact living quarters or aboard a car, boat or plane.
Folding mechanisms vary, with each offering a distinct combination of folding speed, folding ease, compactness, ride, weight, durability, and price. Distinguished by the complexities of their folding mechanism, more demanding structural requirements, greater number of parts, and more specialized market appeal, folding bikes may be more expensive than comparable non-folding models. The choice of model, apart from cost considerations, is a matter of resolving the various practical requirements: a quick easy fold, a compact folded size, or a faster but less compact model. There are also bicycles that provide similar advantages by separating into pieces rather than folding.


In civilized world nowadays we can’t see a road without any bikes but in turn, people are forgetting that it causes pollution and emissions which affects ozone layer and causes several unwanted effects on both living and non- living organisms. Increase in number of vehicles also produces traffic jam and also occupies a huge chunk of space in roads which reduces the size of road that leads to more no of accident which is fatal sometime. The vehicle nowadays has weight which is considerably increased from its predecessor it’s also reduces its portability and it becomes difficult for aged people to drive and park vehicle. There is hike in fossil fuel prices often, which affects middle class people. They
need alternate source of power which comes in a very low price that runs in electricity or battery. Since ordinary vehicles occupy more space they cannot be parked inside the residence or office which makes prone them to weather conditions and leads to high maintenance cost. One of the other problems faced by vehicle lovers is that they park the vehicle outside the residence which doesn’t give vehicle safety.


Foldable half bike with reduced weight when compared to other vehicles which increase its portability that can be taken from one place to other place easily without fatigue. By using simple mechanism like three and four bar mechanism the folding methods can be simplified very easily reducing the complication in front of the others. Since these type of vehicles occupy less space it can be taken easily in to residence and office parking area and can be carried even in to the buses and trains which reduces the chance of theft. These vehicles have only minimum chance to expose to harsh weather conditions. Foldable half bike which runs on battery takes only few minutes for charging and it is capable of holding charge for prolong time.


Detailed Design of Hybrid Half Bike Parts:

  • Steering Column
  • Main frame
  • Motorized hub wheel
  • Chain Sprocket
  • Rear wheels

When compared to other foldable half bikes, the hybrid half bike gives good results. The vehicle was designed using four bar mechanism. In case when the battery power discharged completely it can be used like bicycle with the provision of pedal. The vehicle was designed using mild steel plate if any part is damaged means, it could be replaced easily. The hybrid half bike didn’t produce any emission and it reduces the pollution in earth atmosphere. With the use of electrical and mechanical drive we can reduce the use of fossil fuel that is depleting rapidly. The vehicle requires less maintenance. In future by adding solar panel the battery can be charged with the help of solar energy. The design of the foldable bicycle was based on the standard data available. The fabrication was done using locally available materials. Compared to the foldable bicycles existing in the market, our bicycle is economical and occupies less space. The weight of our bicycle is with par with light weight bicycles available in the market. Though the bicycle is foldable, sleek and having small wheels, complete justice is done to the ergonomics of the rider hence making it comfortable.

  1. Hallow Eng. Sachin
    thank you for sharing you nice projects.
    I will be appreciate if you can send me more about this Design and Fabrication of Automatic Main Stand For Two-Wheelers.
    I need to prepare how to inspire my kids 11-th to build, to motivate them they have gold hand but have difficulty
