E-bike or colloquially known as Electric bikes are everywhere now. Everyone could easily obtain a brand new one; just plug it on your socket to recharge. By the help of modern technology, there are many devices that are going out. And we thank the mass production of China for the growth of this modern battery and practical machines. It’s now very visible that there are more affordable electric bikes that will work for a long period than other motorcycles. Even normal brands like Honda, Kymco, Vespa, and Harley-Davidson are developing, yet not selling an electric version. Some experts assume that the shifting of electric motorcycles is underway already. Nevertheless, the laws in the European Cities aims to prohibit petrol powered vehicles starting from 2020 till 2030.
This e-bike may appear as a modern invention. But here are the big revelations that in early 1978 had already created an e-bike.
Steve Fehr from the Transitron Electronic Corporation creates an electric motorcycle prototype of Harley-Davidson at Honolulu, Hawaii. His team uses a 1971 Harley-Davidson XLH Sportster like donor bike, exchanging a 24-volt to 900cc OHV-twin. The ability of the electric motor will transfer to an automatic four-speed transmission by the use of the belt drive and a series as last drive.
When the time of batteries-most particular the lead-acid- was very heavy, and the electric bike model was certainly heavy. It measures at 286 kilograms or 682 pounds. But it is set to accelerate the distance from 0-50 miles/h or 80 kilometers/h in six seconds. It should maintain the engine over 2,500 rpm.
The 4 deep- cycle batteries could give a running time for six hours. To check the performances of the bike use the dual ammeters for measuring amps, Tachometer, featuring an electric speedometer and the mounted to the handlebars.
At that time, the Transitron Electronic Corporation did not continue the development of the project because of lack of money. However the Brooks Steven, legendary designers, who impart such essential vehicles as Jeep Wagoneer, the 1962 Studebaker Hawk Gran Turismo and the 1949 Harley-Davidson FL Hydra Glide saw an interest in the project.
A 67-year-old, Steven who worked with Fehr helps to try the prototype. They test their prototype in Wisconsin and racked up 579 km on-track testing.
After they invested Php 14.1 million to the project they surrendered the bike and stayed on Stevens’ transportation museum in Mequon, Wisconsin to display. The bike was kept until the museum was closed.
Prophetically, Fehr’s Harley-Davidson MK2 electric Sportster sold in 2014 for US$11,000 at RM Sotheby’s in the same year also Harley-Davidson introduces its LiveWire electric bike prototype.
