The History of Electric Bikes
The word ebike has been in common use since the early 2000’s but can you guess how old the electric bike actually is?
The idea of an electric bike is almost 130 years old! And in the decade before the electric bicycle there were forward thinkers experimenting with electrically powered tricycles in both France and the USA. We will mention these experiments below but the beginning of the electric bicycle has to begin with the invention of its predecessor: the bicycle.
THE BEGINNINGS OF THE BICYCLE
Bicycles first appeared in the latter half of the 19th Century and the most popular version of a bicycle was the “High Wheeler” or “Ordinary”, a.k.a the penny-farthing. Before this, lever and geared tricycles were the most popular forms of wheeled transport; besides horses drawn carts. The High Wheeler was popular because the large wheel at the front allowed the rider to travel a considerable distance with just one rotation of their legs, because the pedals were fixed to the wheel, i.e. not geared. These bikes came with the considerable danger of falling the far distance from the seat to the floor, often 5 or more feet! Hence the name of the bicycle that replaced them: The Safety Bicycle.
Safety bicycles are very recognizable because they’re so similar in appearance to the bicycles we ride today. They were first invented in the 1870’s but didn’t catch on until certain technological advances, specifically direct steering and gears, were added. Since it’s rise to stardom in the 1880’s and 1890’s the safety bicycle has gone through many evolutions and modifications, including many attempts at electrification!
THE EVOLUTION OF THE ELECTRIC BICYCLE – PART 1
The first part of the evolution of the ebike follows the “bicycle craze” of the late 19th Century, which arose from birth of the safety bicycle. This part of the evolution of the electric bicycle can be traced through patents registered with the US patent office, and it is these that we will use for reference here. But it all begins with two men who tested electric propulsion on tricycles, on opposite sides of the Atlantic, 10 years apart.
Gustave Trouvé and The Trouvé Tricycle
In 1881 Gustave Trouvé wanted to experiment with electrical power and tricycles and he did so by taking a British built tricycle and incorporating an electric motor into it. He tested this in Central Paris and, although the test was deemed a success, he was unable to get it patented.
Undeterred, he took his idea and modified it to power his boat up and down the Seine river. He managed to patent that invention and is credited as the inventor of the outboard motor. Perseverance pays off!
Monsieur Graffigny and The Graffigny Tricycle
Monsieur Graffigny added a battery and geared transmission to a tricycle. Along with its rider this was a heavy contraption, weighing in at around 300lb! However, on a test track, it did manage speeds of around 12mph and covered 50 miles total. Quite impressive, but there was a large danger of falling off because of a high center of gravity.
Ogden Bolton, Jr and The Direct-Drive Rear Hub Motor
Mr Bolton submitted a patent for what has today become the widest and most used style of motor in an electric bicycle, the direct-drive rear hub motor. This is what we here at Aventon use in our ebikes, so you could say that our ebikes can trace their lineage all the way back to 1895!
The main difference between hotebike motor and the modern versions we use now is that his was brushed, rather than brushless. Besides that though there are few differences besides modernization; hotebike was also made to be water and dirt proof, the speed was controlled from the handle bars, and the battery hung from the frame between the biker’s legs.
THE EVOLUTION OF THE ELECTRIC BICYCLE – PART 2
All of the above progression in the world of electric bicycles seems like it would have led to a rise in the popularity of this as a form of transportation. Unfortunately, with the advent and mass production of motor vehicles, electric bicycles fell by the wayside. From here we have to fast forward around 100 years, to the turn of the 21st Century, in order to see the technological advances which would launch the electrical bicycle into the huge rise in popularity it is experiencing now. What were these technological advances?
Battery technology – Lead acid batteries, the type which start your fossil fuel powered car, are heavy, cumbersome, and having these on an ebike was not overly practical. Lead acid batteries do not provide as much power as modern Lithium-Ion batteries.
Lithium-Ion batteries, commercialized in the early 90’s, offered an increased capacity along with more power and, importantly, they do this whilst weighing a lot less than their lead acid grandfathers. This lightened ebikes and gave them more power and a larger range, making them much more appealing to a much larger segment of the population.
Sensors and Microelectronics – These items are essential for the modern ebike and without them many of the functions we use and love, such as: different levels of pedal assist, battery level monitoring, and electronic speed monitoring; would not exist. Such functions have arisen from the technological boom we’ve seen over the past few decades and would have been unheard of 100 years ago, during the first era of ebike evolution.
These technological advances help not only to provide increased functionality and more options to the rider of an ebike, but they also greatly help increase the safety of riding one. Such a topic is even more prevalent in today’s, bustling society.
Pedal Assist – In 1989 Michael Kutter invented one of the most important progressions in the modern world of electric bikes, the “Pedelec”, standing for Pedal Electric Cycle. This is a function we now know as pedal assist and his idea was to have the motor start running once the rider began pedaling, negating the need for a throttle. Before his invention everyone had always used a throttle function, without using the pedals (which is where some would argue that many of the previous designs were for electric motorbikes, but we’ll let you be the judge of that one).
Michael first put this on a personal bike before helping a company create a commercial version in 1992. Since then pedal assist has become quite omnipresent in the ebike industry, both as an assistance and a safety function.
FROM THEN UNTIL NOW
The early 90’s saw the re-invention of the electric bicycle and in the early 2000’s ebike became the term to be using. Now we’re seeing an ebike revolution as their popularity has steadily grown for close to 20 years, with no current sign of abating! 130 years after the safety bicycle began the first bicycle craze, you could say that we are now entering the world’s first ebike craze as people in the 21st Century clammer to get themselves one of these trendy, environmentally friendly modes of transport.
