Consider me. Or consider yourself. Presumably an average human being of average weight. These averages vary considerably in different parts of the world, from 60 kilos or less, to 90 kilos or more. Looking back at the various means of transport that I have commonly used in the past five decades, I made a list of their approximate weights for comparison. My own weight has changed (increased!) by 5 kilos during this period, from 75 to 80 kg.
Bicycle: Throughout my schooldays, I used a single speed bicycle to take myself (40 to 65 kg.) to school and back. I assume bicycles weighed around 25 kg. in those days. In any case, the means of transportation was around a third of my own body weight. I loved the song of the open road. Most days I arrived at school in a lather of sweat, but no one really bothered about that.
My first job was as a travelling salesman and the most efficient way to do this at the time was with a motorbike or scooter. Traffic congestion was not yet a problem in the 1970s to 90s. I loved the song of the open road. Most days I arrived at work or at a customer feeling dapper and cool, even though a bit windblown. The weight of the motor-scooter or motorbike I owned or rode at various times in this period varied from 130 to 150 kg. My own weight at this time was a svelte 75 kg.
From the late 70s to the 1990s my preferred mode of transport was a private car. I loved the song of the open road, although traffic was constantly increasing. Loved to drive long distances on holiday. Car weights varied from 840 kg (1976 first generation VW Golf) to 1400 kg (same model 25 years later) to 1700 kg (minivan). In spite of long distance holiday travel with family, 90% of the annual miles were clocked commuting to work and back. i.e. 1000s of kilometers with just one occupant. i.e. using 1400-1700 kg to transport 80 kg of human being. Forget the song of the open road! Most daily commutes were exercises in creeping through congested streets and highways, impatiently waiting to get to work or home.
From the early 2000s onwards, my thinking about the daily commute evolved (?) as follows. Car (1700 kg, 40 minutes), bus (kg irrelevant, 80 minutes), bicycle (16 kg., 70 minutes). The bicycle was definitely a step forward in efficiency and economy. It cost practically nothing, and also gave added health benefits, although I arrived in a lather at work, as I did in my school days, and had to repair to a toilet for a cat-wash and a change of clothes.
Around 2005, I began to yearn for pedal assist on my bicycle and began to look around for electric models. There were none available as far as I could see. Sometime in 2006, I found a German website on the internet that advertised an electric bicycle with a 1 year guarantee, a 7 kilo NiCad battery pack, and no range specifications. I was tired of a steep hill on my daily commute (36 km per day), so I ordered the bike sight unseen and two weeks later, took delivery of a giant cardboard carton with MADE IN CHINA printed on the sides. It weighed 32 kg with battery, had seven gears and was a real pain to carry up and down to the cellar where I stored it overnight.
But it did the job nicely. The hill was a problem no more. And the range was around 30 km. Unfortunately, NiCad batteries suffer from a memory effect, and I could not charge it in the office for the ride home, so I got minimal assistance on the dreaded hill with a fading battery.
Ah, the perfect solution! Sometime around 2008, I saw a beautiful 24-speed KTM with the cutest little Li-ion battery that was good for 60 kms of pedal-assist riding. By this time, I had moved homes and my daily commute had increased to 50 km. Here was the answer to my commuting problems. The KTM bicycle weighed 22 kg, I weighed 80 kg., and the electricity cost me around €0.30 for 100 km (30 cents). My friends considered the electric bike expensive. It was expensive, in bike terms, but in reality cost about as much as the annual service of the average 1700 kg. monster. Maybe that’s comparing apples and oranges, you say. But such comparisons are ok when you’re riding an apple, and have gotten rid of the orange. Needless to say, I sold the 1700 kg. monster and have lived happily ever after.
Nowadays people tell me, you can’t ride around on a bicycle at your age! It’s too dangerous to ride a bicycle in this murderous city traffic. True. But I wear a helmet and try to ride cautiously. I’m happy carrying my current 79 kg. on two wheels weighing 22 kg., and wouldn’t dream of carrying it in 1700 kg. as I used to do. The difference in weight (ca.1,678 kg) I like to think of as the weight of fear. That’s quite a lot of fear to carry around in one’s life. Best to get rid of it!
