“In a characteristic energy flow comparison, a grid-charged battery driving an electric motor will provide mechanical energy about ten times more efficiently when compared to a human eating a typical diet. For personal travel between 5 and 30 miles per day, the electric bicycle offers the lowest environmental and fafrees f20 personal monetary cost, usually without increasing urban travel time”

That may sound obvious, but it’s the primary advantage. A good electric bike effectively flattens slopes, increasing your average speed and eliminating the ‘groan’ factor when a gradient has view. Provided you supply a reasonable amount of effort, you can expect to climb slopes of 1 in 10 (10%) on an electric bike with ease, and clear a maximum gradient of 1 in 7 (14%), or much more. In hilly country, the effect is nothing short of marvelous.
It sounds unlikely, doesn’t it? But the mathematics is compelling. Think of a steep and busy road, with cars climbing at 30mph. If you previously slogged the hillside at 6mph, but can tackle the same gradient at 12mph with an electric bike, you will see 33% fewer cars, and they’re going to pass you at 18mph rather than 24mph. Or at least, we think that’s correct.
No matter what figures, there’s no doubt that an electric bike helps to keep you out of danger. The same general principle applies to road junctions : the faster your acceleration, the sooner you can get out of trouble. And with no need to rush the slopes, you won’t be convinced to ride all downhill at breakneck speed… another useful safety feature.
Surely the standard bike will keep you fitter? That, of course, depends how much : whenever : you use it. Research (b) has found that 46% of conventional bikes are used only a few times a week, with a further 30% being used once a fortnight or even less. In comparison, a recently available survey of electric bicycle owners reveals that a third ride their bike one or more times a day and 81% use the bike one or more times a week (c).
The figures confirm our experience that an electric bike typically gets used at least doubly often as a conventional machine.
Because riding an electric bike is more enjoyable in hilly country, into strong gusts of wind, or when carrying heavy loads, users make better use of them. The motor provides up to half the effort, but more regular use means more exercise for the riders.
Sweat may not be a serious issue when you’re out for a leisure ride, but it’s more important if you’re cycling to work. And some employers are rather grudgingly providing showers and other facilities for cyclists, the great majority have no objective of doing so. An electric bike eliminates the problem at source. In summer, it’s possible to maintain a normal schedule by transferring a bit more load to the electric motor. In chillier weather : or if you feel in need of exercise : just throttle back, or turn the motor off.
Clean & Green
Electric bikes obviously consume energy, where a conventional bikes does not (provided we ignore the environmental cost of growing and processing food : see below). However, the amount of energy used is very small compared to a moped, motorcycle or car. Besides fuel, the only consumables are the batteries, and these can normally be recycled when life-expired. As for energy use, electric bikes typically consume fuel at an average rate of 100 to one hundred fifty watts of electricity, against 15, 000 or so for a car (admittedly travelling much faster). In terms of fuel consumption, an electric bike defines about 800-2, 000mpg (290 : 900 litres/kilometre) (d). No other retail available vehicle can match figures of this kind.
Whether or not it’s hard to place these numbers in your own lifestyle, think of a 100 watt electric bulb burning for an evening : that’s enough energy to propel an electrically-assisted bike for 20 to 40 miles…
There are several nonsense talked about sustainability in transport, but an electric bicycle can be made genuinely sustainable. Purchase electricity from a ‘green’ supplier, or generate your own with a roof-mounted windmill or solar power array (see Solar power facts), and the vehicles’ fossil fuel consumption will be zero. Surely the standard bike does that already? On condition that you grow the food you consume whilst riding it. Unfortunately, most modern food production and distribution is so fuel-intensive that the consumption of a typical cyclist is not very good.
The theory is that a car can average a high speed, but in studying speed often falls below 10mph in cities. The problem is congestion : bikes bypass this to some extent, but they’re still kept to the road network. An electric bike can maintain a higher average speed when compared to a bicycle but take advantage of the same network of cycle facilities, giving access to channels that cars and bikes cannot reach. The result is often a faster door-to-door journey time than any other mode. And by taking advantage of the uncongested cycle network, but eliminating slopes and headwinds, electric bikes are often the most consistent mode of travel.
High Resale Value
Electric bikes are new technology, and it’s early days yet, but the evidence points to a much better resale value when compared to a conventional bike. True, a typical electric bike costs more to buy, at £400-£1, 000, but it seems you’ll get most of that back if you sell the device on.
Motorised, Without the Red Recorded argument!
You know how it is… MOT due, log book missing, insurance costs rising year on year. Electric bikes are treated just like ordinary sports stuff for legislative purposes, so there’s absolutely no registration or legislation to worry about. You are of course free to insure the device if you wish, but there’s no compulsion to do certainly not enjoy it!
