The BugE is a one-passenger, three-wheeled battery electric vehicle designed by Mark Murphy of Blue Sky Design in 2007. It can reach up to 40 mph in standard form, and can run for 30 miles on a full charge. The BugE is licensed as a motorcycle and can run on all major streets in the United States of America. A fully completed BugE vehicle is as of May 2015 is listed at US$5,732.30.
Origin
The BugE is a motorcycle like vehicle that is created by Blue Sky Design LLC. Blue Sky had designed a previous vehicle called the Gizmo. The Gizmo was a more costly vehicle, with over 17 major components. The 2005 models of the Gizmo were priced at $12,000. Through a series of collaborations of many small business mainly based in the Pacific Northwest, the idea for a smaller and more cost effective vehicle was designed. The man credited with the main concept design of an “almost-fully-faired three-wheeler” is named Mark Murphy, of Creswell, Oregon, who is also the owner of Blue Sky Design LLC. Murphy is known for being a “designer on concept projects for companies such as GM, Chrysler and BMW.” “His design criteria [for the BugE] was for ‘a simple, low cost personal mobility vehicle." On February 5, 2007, the BugE had its first run. It drove out of a garage and down a flat suburb street. The run was captured and put on YouTube by one of the creators. Not even a month later the BugE was certified as a street legal motorcycle.
Design
The BugE has handlebar steering, a bucket seat, uni-shock suspension, a parking brake, low-drag tires, drum brakes and three mag wheels. A rounded fairing reaches up and over the driver for the full length of the vehicle and reduces the vehicles aerodynamic drag. The fairing can pushed up and tilted forward to allow a driver to enter the vehicle. Attached to the fairing and acting as a sort of windshield is a clear canopy made of optically blown acrylic. Behind the fairing and canopy is an optional removable rear canopy. All vehicle controls are operated by the handlebars, including the throttle and brakes. The battery compartment holds a 48 volt battery and is located underneath the vehicle. The BugE has one cargo compartment located in the front of the vehicle between the two front tires. The cargo compartment is designed to hold two large or four small bags of groceries and can carry up to 25 pounds of cargo. In addition to the single compartment, the driver's seat is designed to withstand up to an extra 10 pounds of cargo via a small backpack that can be hung from the seat back. In the base model, the seat is bolted into place. This can be made to be adjustable with additional modifications. The BugE base vehicle kit is made of 17 major components and 75 total parts and weighs 350 pounds fully assembled. The simple electrical system has only five major parts. Of the five major electrical parts, only two of them move: the potentiometer and the motor. The three non-moving parts include the batteries, of which there are four, all connected in the battery compartment, the controller, and the battery charger. All of the pre-assembled kits are provided by vendors in the United States and 70% of their materials are made in the Pacific Northwest.
Function
Like most electric motors, the BugE motor produces torque and low-end power suitable for efficient stop-and-go driving. The engine does not idle and instead turns off during traffic stops. A BugE can be charged by plugging it into any 120 volt wall outlet. The BugE website claims “Energy efficiency is 1 cent per mile” and estimates the cost of a full battery charge at around 40 cents. The slim design of the vehicle allows it to be parked in spaces up to four times smaller than the average parking space. The height of the BugE brings the driver to a height level similar to other automotive drivers, and the scope of the fairing help to make the smaller vehicle visible in traffic. The one piece fairing deflects rain and wind from hitting the driver directly, but its lack of windshield wipers causes water to bead up on the fairing during wet-weather driving. Because the fairing is attached to the vehicle via the front axle, it is prone to clunky vibrations at low speeds and on turbulent surfaces. The nature and position of the motor produce a constant, loud mechanical sound much like a motorcycle. The weight limit for the vehicle, including the driver and all carried cargo, is 200 pounds.
