What Are the Advantages of Electric Bikes?

"In a systematic energy flow comparison, a grid-charged battery driving an electric motor will provide mechanical energy about ten times more efficiently than a human eating a typical diet. lowest environmental and personal monetary cost, usually without increasing urban travel time "
From Energy, Global Warming, and Electric Bicycles Energy Flow Analysis with an Emphasis on Personal Transportation

1. Hill Climbing
That may sound obvious, but it's the primary advantage. A good electric bike effectively flattens hills, increasing your average speed and eliminating the 'groan' factor when a gradient comes into view. Provided you supply a reasonable amount of effort, you can expect to climb hills 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 miraculous.

2. Safety
It sounds illegally, does not it? But the mathematics is compelling. Think of a steep and busy road, with cars climbing at 30mph. If you previously slogged up the hill at 6mph, but can tackle the same gradient at 12mph with an electric bike, you will see 33% fewer cars, and they will pass you at 18mph rather than 24mph. Or at least, we think that's correct.

Whatever the 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 hills, you will not be tempted to ride downhill at breakneck speed … another useful safety feature.

3. Personal Fitness
Surely a conventional bike will keep you fitter? That, of course, depends how much – if at all – you use it. Research (b) has found that 46% of conventional bikes are used only once or twice a week, with a further 30% being used once a fortnight or even less. By contrast, a recent survey of electric bicycle owners reveal that a third ride their bike at least once a day and 81% use the bike at least once a week (c).

The figures confirm our experience that an electric bike typically gets used at least twice as often as a conventional machine.

Because riding an electric bike is a great deal more enjoyable in hilly country, into strong winds, or when carrying heavy loads, users tend to make better use of them. The motor provides up to half the effort, but more regular use means more exercise for the rider.

4. No Sweat!
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. Although some employers are rather grudgingly providing showers and other facilities for cyclists, the great priority has no intention of doing so. An electric bike eliminates the problem at source. In hot weather, it's possible to maintain a normal schedule by transfering a bit more load to the electric motor. In colder weather – or if you feel in need of exercise – just throttle back, or turn the motor off.

5. 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. Beside 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 150 watts of electrical energy, against 15,000 or so for a car (admittedly traveling much faster). In terms of fuel consumption, an electric bike achieves about 800-2,000mpg (290 – 700 liters / kilometer) (d). No other commercially available vehicle can match figures of this kind.

If it's hard to place these numbers in your own lifestyle, think of a 100 watt electric light bulb burning for an evening – that's enough energy to propel an electrically-assisted bike for 20 to 40 miles …

6. Genuinely Sustainable
There's a lot of 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 panel array (see Solar Power facts), and the vehicles' fossil fuel consumption will be zero. Surely a conventional bike does that already? Only if you grow the food you consume whilst driving it. Unfortunately, most modern food production and distribution is so fuel-intensive that the consumption of a typical cyclist is not terribly good.

7. Faster travel
In theory a car can average a high speed, but in practice speed often falls below 10mph in cities. The problem is congestion – motorcycles get around this to some extent, but they're still bound to the road network. An electric bike can maintain a higher average speed than a bicycle but take advantage of the same network of cycle facilities, giving access to routes that cars and motorcycles can not 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 hills and headwinds, electric bikes are often the most consistent mode of travel.

8. High Resale Value
Electric bikes are new technology, and it's early days yet, but the evidence points to a much better resale value than 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 machine on.

9. Motorized, Without The Red Tape!
You know how it is … MOT due, log book missing, insurance costs rising year on year. Electric bikes are treated just like ordinary bicycles for legislative purposes, so there's absolutely no registration or legislation to worry about. You are of course free to insure the machine if you wish, but there's no compulsion to do anything but enjoy yourself!

Electric Scooter Repair – How To Repair An Electric Scooter

Every machine needs maintenance and repairs and an electric scooter is not an exception to this. Of course as compared to a gas powered scooter the amount of maintenance required for an electric scooter is much less, but needs care just like every vehicle.

Gas powered vehicles machines are complex systems with so many things to look after on the other hand an electric scooter is a very simple machine. A person with little knowledge of electrical circuits can repair it on his own without any need to look for a mechanic. But if knowledge of electrical circuits is not there, many options are available.

If you have an electrical scooter in need of repair the first thing you can do is take it to a standard mechanical workshop and ask for help. Since normal gas powered scooters also have electrical circuits in them, every mechanic will have at least some basic knowledge about circuits.

If they refuse to repair it you can simply ask the manufacturer of the electric scooter regarding any special workshops where such electric vehicles are repaired. Since selling electric scooters is a business for them it is strong possibility that they have special tie-ups with workshops around the country to service their scooters.

Depending upon the kind of repair your scooter may need a week or for minor repairs just a few hours. Sometimes it is just a matter of charging the battery (if you don’t charge it regularly) ad it’s ready to drive again.

However it is necessary to understand that “prevention is the best cure”. Regularly use your electric scooter and don’t forget to charge it regularly too. If you are way for a few days from your home, you can carry it with you or store in way that it is safe from moisture. Normally it is advisable to look for repair shops before you buy an electric scooter bur since these machines are not complex, they can be repaired easily without much expenses on your part.

Homemade 12V to 48V DC-DC Converter Battery Charger for Electric Scooter/Bike



This is a PC board I made so I can charge a 48V seal lead acid battery from any 12VDC source. This design is simple and uses an off-the-shelf audio crossover coil. It charges my battery from a 12V source that gets switched on once the sun goes down. In the morning my batteries are ready to go and it didn’t cost me anything. Energy from the sun. However I can use with and 12V source that can provide 2-3 amps of power. There is a special circuit that will stop the SMPS once the battery level low around 11 volts. Next day the sun comes up and charges the 12V battery.
