A Change of Pace
How we Came to Electrify Our Cycling
Barry and Margaret Williamson
Kato Gatzia Pelion Peninsula Northern Greece
October 2019
Barry
has been cycling for 70 years and Margaret for 54, sharing the road for the
last 30 or more of these eventful years. Our rides have taken us round the
world, across Australia, the length and breadth of New Zealand, across the USA
twice (see left, Barry at Key West having ridden from Los Angeles) and
across Europe (east and west) several times, cycling in every European country
as well as Turkey, Israel, the Palestinian Territories, Tunisia, Morocco – and
India. We have made multiple crossings of the Alps, the Pyrenees, the Rockies,
the New Zealand Alps and Australia's Great Dividing Range. Full details of these
rides are among over a hundred cycling articles on our website MagBazTravels.
On
these journeys we have always ridden traditional English Touring Bicycles,
unique in the world in their specialised function and design. Taking heavy
loads with five bags each (see Margaret
in the New Zealand Alps, on the right
and below) the bikes retain the stability, energy efficiency and
sprightliness that makes light of long days in the (Brooks Leather) saddle. The
characteristics of the bicycles come from the largest of wheels (700 mm or
28”), a light but strong steel frame, long wheelbase, clearance for mudguards, relaxed
geometry, up to 30 wide-ranging gears (3x10 derailleur), wide drop handlebars
(offering 5 different positions for the hands), toes clips and straps (for
sturdy shoes which are also OK for walking), 3 cages each for a 750cc water bottle,
high pressure German Schwalbe
Marathon Plus Tour tyres (at 80 psi and puncture proof) and above all
the optimum geometry for the three points of contact – feet, seat and hands.
The
long-distance touring bike can be compared with the horse that carries loads on
its back for long distances – for mail, for urgent supplies, for cowboys – with
speed, stamina, sturdiness, strength, reliability and willingness. Contrast the
skittish racehorse (the racing bike), plodding carthorse (the fat-tired (sic)
mountain bike), the hunter good at jumping (the BMX) or the tame pet pony (the shopping
bike). The folding bike might fit into the boot of a car, but we don't know how
it fits into this extended metaphor.
At
a typical 0.15 calories per gram per kilometre, the touring bicycle is the most
energy efficient means of movement of any animal, fish, bird or any other human
invention. For a 70 kg cyclist on a 15 kg bicycle, this adds up to about 50 kJ
for a 16-km (10-mile) ride: a single 5 gm square of Cadbury's milk chocolate
provides 110 kJ! For the same energy
requirement, a good touring bike gives a factor of 4 compared with walking: for
example, a typical cycling day of 60 miles is equivalent to a 15-mile walk and
a 100-mile ride is equal to a walking marathon. Regrettably, the power required
for the cyclist to overcome wind resistance rises as the cube of the relative
wind speed, making patience an essential virtue! On the other hand, we crossed South Australia's 750-mile wide Nullarbor Plain (above) in 12 days, thanks to a good westerly wind.
For
many years we rode touring bicycles made for us in Sheffield by a couple of
ex-steel workers, appropriately called M & B Cycles (started by Andy
Middlemiss and Vernon Barker in 1979). For a number of years they were serviced
and maintained by Paul
Hewitt
at his excellent shop and workshop in Leyland (Paul's wheel-building is
acclaimed by Sir Bradley Wiggins). British industry's loss was our gain. In
2007, Paul built two of his Cheviot
SE touring bikes (Barry's bike on the left) to our specifications, based on measurements taken on his
bicycle-simulating jig, and they have served us very well for over 10 years until last Christmas.
However,
this winter freshly arrived in Greece and faced with its cyclists' dream-world
of endless empty roads linking networks of remote mountain villages, we began
to consider many of the developments in cycling design over recent years. In no
particular order, the following list of 28 new-to-us features is the result of these ruminations:
Rear Hub Gears
12-Speed Gears
Handlebar Gear Shifting
Electronic Gear Shifting
Automatic Gear Shifting
Straight Handlebars
Aluminium Frame
Disk Brakes
Hydraulically-operated Brakes
Self-adjusting Brakes
250-Watt Electric Motor
408 Watt-hour Battery
Power-assisted Pedalling
5-Power Levels selected from the Handlebars Power-assisted walking Solid Rear Axle
| Automatic Low Gear Start Chain Tensioner Front-fork Air and Spring Suspension Seat Suspension Rear Wheel Lock Built-in Front and Rear Lights Lights Switched from the Handlebars Bar-end Extenders Spring-loaded Clamp on Rear Carrier Kickstand Backlit Handlebar Display Handlebar Display: Speed, Trip Time, Trip Maximum Speed, Trip Distance, Total Distance, Time of Day, Gear Number, Battery Level, Lights On/Off, Effort, Estimated Range |
What
could we do about these missed developments, at this late stage in our cycling
lives? The process began when we wrote to Paul Hewitt: '. . . . we never thought that we would write this
email, but . . . . .' and it ended when we returned to Greece a month later
with one Volt Infinity Shimano
STEPS Electric Bike and one Volt Infinity LS
Shimano STEPS Electric Bike. On
the left, our first sight of the new bikes in Paul's shop.
The
bicycles vary only in size and both contain all 28 of the features listed above.
We have also each retained essentials such as 700mm wheels and Schwalbe
Marathon Plus Tour 35C tyres, mudguards, bottle cage, bell (essential on cycle
paths), bar-end mirror, frame-fitting pump, handlebar and rear pannier bags, toe clips
and straps.
The electric motor helps
to turn the cranks but it doesn't start work until the cranks are first turned by
the cyclist and the harder the cyclist pedals, the more power the motor provides.
In addition to 'off', the motor's maximum power can be selected from 3 levels: 'Eco', 'Normal' or 'High'. By EU/UK law (except in Northern Ireland), the motor is
limited to a maximum of 250 Watts (a third of a horsepower) and it must cut out automatically above a
road speed of 15.5 mph (25 km/h).
We have now ridden over 5,500 km (3,450 Miles) on the bicycles in England, the Netherlands, Bulgaria, Turkey, Poland, Estonia, Finland, Sweden, Germany, Czechia, Austria and now Greece. The riding ranges from climbs of 4,000 ft (1,200 m) in the Greek Peloponnese and off-roading on the Yorkshire Moors and in the forest of Scandinavia, to long rides on the riverside cycle paths of Germany and Austria.
The batteries are rated at less that half a kilowatt-hour (just a few pence worth), although we rarely use more than a small percentage of this on a single ride and then only on hill
climbs or against wearying head winds. Yet that small flow of extra energy when needed has transformed our riding, giving us a
greater range, wider scope and more enjoyment.
So far we have found the 'Eco' mode more than adequate to turn hills from a pain
into a pleasure. It's a revelation that we can have the extra power in hand ('Normal' and 'High') when needed, for example when we climbed the long 33% hill between the
villages of Egton Bridge and Egton on the North York Moors). This means that we are always completely in control of how much fitter we want
to become. Rather than needing to get fit before tackling long strenuous rides,
we get fit while undertaking even longer less strenuous journeys!
To
write that this has re-invigorated, re-invented and re-freshed our joy in cycling is putting it mildly: there are many more words still waiting in the dictionary
that we could use, all beginning with 're'. Our traditional touring bicycles
are at ease in a lock-up garage on the outskirts of Blackpool, waiting to see
if we change our minds and re-turn (a word we are unlikely to use).

Carado motorhome on its 950-mile journey from England back to Greece last January via the
P&O overnight ferry from Hull to Zeebrugge, and the Minoan overnight ferry
from Ancona on Italy's Adriatic coast to Igoumenitsa near Greece's border with
Albania.
