Kaylad-e | trike evolved

Kaylad-e is the end result of a thesis/graduation project, presented in late 2013.

The brief was to design a hybrid vehicle for commuting in the modern metropolis.

Kaylad-e aims to help people make the shift to active means of transport in a safe, stylish and enjoyable manner.
Everyone enjoys different things in an experience. This is due to different mindsets, culture, situations, environment etc.
Fun and enjoyment was one of the most important guidelines of Kaylad-e.
The first goal was to remove as many of the stress factors and discomfort of commuting by bicycle as possible. Thus enabling the rider to enjoy all the aspects of the ride.
The second was to create a product that will last and mature over time. Choice of materials and the ability to adapt to new technology [battery, motor etc.] are a crucial step in that direction.

Ergonomic study [huge thanks to Bill]
Ideation sample #1
Ideation sample #2
Ideation sample #3 Bag rack Concepts
Ideation sample #4 Integrated lock and battery Concepts
Integrated lock The lock is always there and ready for use, minimizing the staff the user has to buy and carry in order to secure the vehicle. Specs - 10mm hardened steel chain - 850mm long
Battery The battery can be removed when needed. The user doesn't have to carry the hole vehicle in order to charge it. It automatically locks onto the frame when mounted. Theft possibility is minimized when stopping for a short period [coffee, shopping, etc.]. The position of the battery contributes to a low center of gravity and makes it easy to mount/unmount. Specs - 36V - 400Wh - 2.4 Kg [5.3 pounds]
Mid drive motor Provides a smooth ride. Contributes to a low center of gravity and better weight distribution. Low maintenance. Specs - 250Watt - 3.9 Kg [8.6 pounds] - EU ready [no driving license needed]
Belt drive and belt guard
Gear hub and dropout lock Gear hub provides a smooth ride and it is a low maintenance solution. Dropout locks and secures the rear wheel. Discourages theft of easy removable parts [major concern in urban commute].
GPS and saddle lock A GPS is integrated in the seat tube, enabling the user to alert the police in case of bike theft and recovering the vehicle. It is powered by a small battery that is charged when the main battery is mounted. The saddle is locked in the frame by a rivet, rendering it hard to be removed.
Integrated lights Modern bike commuters in most cases share the road with motor vehicles. It is crucial for the safety of the rider that he/she is visible to the rest of the road users, as well as, he/she has good visibility of the environment. Kaylad-e has integrated head, tail and direction LED lights. Headlight has 1100 Lumen hi and low beams. Tail light signals when the rider is braking.
Bag rack Commuters need to carry baggages [briefcases, backpacks, shopping bags etc.]. Placing the belongings in front of the user enables him/her to survey them, rendering theft almost impossible. The commute often include stops to the super market or other stores. The baggages must be secured when the vehicle is in motion.
