What is an electric bike? 

Electric bikes in simple terms are pedal bikes which are assisted by an electric motor. Electric bikes have been incredibly popular for many years in Europe and Asia. We are now seeing their popularity spread to the UK. 
 
Electric bikes generally have several levels of pedal assist , making cycling as easy or hard as you want and some models even have a throttle mode, which allows the rider to 'twist and go'.  
 
Due to the legislation there is no Road Tax, MOT or insurance required. The rider also does not have to have a driving licence or wear a crash helmet. They do however need to be over 14 year old. 

What is the range of an electric bike? 

The range of a fully charged battery varies. It is usually between 20 and 60 miles with gentle pedalling. Most of the power is drained when moving off and on hills, so pedalling at these points will preserve the power. Distance varies with the weight and size of the rider, the terrain encountered and strength of the head wind: The range can be greatly extended by adjusting the power level of the bike. This is done simply at the press of a button and reducing the power level uses less battery and increases the range 

Does the battery recharge when I pedal? 

We are asked the question by almost every customer. The answer that applies to most electric bicycles is no, but you preserve the battery by pedalling and can extend the range considerably by selecting the lower levels of assistance. Generally with modern battery technology ranges vary from 20 to 60 miles depending on the size of the battery, it is more than enough for most people. Bear in mind you could always take the charger with you and find a friendly pub or coffee shop and put the battery on charge for an hour. A large percentage of power goes back in during the first hour of charging. 

How long does the battery last? 

Again this varies, but a battery that is used correctly should last around 1000 charges, which could equate to around 40000+ miles!! Bear in mind that if the battery runs out, you can always pedal! It is not like running out of petrol. 

Do I need to pedal? 

On many of the models that we sell, you can either pedal or use the throttle.  
Most people mainly use the pedal assist mode, which makes pedalling much easier than a non electric bike, but in certain circumstances for some people, the option to use the twist throttle is invaluable. With the new legslation from January 2016, the throttle will only take you to 4 mph without pedalling. However if you rotate the pedals slowly, on most models the throttle will then operate up to the 15.5mph. You may need to put more effort in to help on steep hills. 
 
 

How much assistance do I get? 

A popular misconception with electric bikes is that they are too easy to use. This used to be the case when there was only one power level. However on most modern quality bikes, the rider has the choice of how much or how little assistance they require, with often up to 5 power settings to choose from. On level ground or gentle slopes, the power can be turned down but at the touch of a button increased, as more assistance is required. This not only enables the rider to choose how easy or hard they would like to work, it also extends the range of the battery. This ability to adjust the amount of assistance suits the majority of electric bike riders who still want to cycle, but do not want to get off or struggle when it comes to the hills. With the power assistance of an electric bike they are still able to get the healthy exercise they would from riding a conventional bike. 
Like people, as batteries age, their performance gradually decreases. (Actually, in the first 20 or so charge/discharge cycles, the battery's range can actually increase) 

How fast will it go? 

To gain exemption from road tax, road insurance, MOT tests, vehicle registration, the requirement of a driving licence and wearing a motorcycle helmet, the speed under power is restricted to 15 miles per hour. They can of course be cycled beyond this speed. 

Can you deliver the bike to my house? 

We are happy to deliver bikes free of charge within a 40 mile radius of Penryn. This includes Bodmin, Wadebridge, St Austell, Padstow, Newquay, Falmouth, Redruth, Cambourne, Helston, Penzance, St Ives and Hayle. We can deliver further afield for a nominal fee. 

What are the running costs? 

Other than charging the batteries at a cost of less than 10 pence per full charge, there are no other significant running costs. You should carry out basic maintenance as you would with a normal pedal cycle; however the electronic parts of the bikes are designed to be trouble and maintenance free. 

What are the advantages of an electric bike? 

1. Hill Climbing/wind 
That may sound obvious, but it's the primary advantage. An electric bike effectively reduces the gradient of 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. 
Another bugbear for a cyclist is fighting against a head wind. This can be just as hard as climbing a steep hill, but with the beauty of motor assistance, headwinds are no longer a problem. 
2. Safety 
It sounds unlikely, doesn't it? But the mathematics is compelling. Think of a steep and busy road, with cars climbing at 30 mph. If you previously slogged up the hill at 6 mph, but can tackle the same gradient at 12 mph with an electric bike, you will see 33% fewer cars, and they will pass you at 18 mph rather than 24 mph. Or at least we think that's correct. 
 
3. Personal fitness 
Surely a conventional bike will keep you fitter? That, of course, depends on how much - if at all - you use it. Research has found that only 16% of conventional bikes are used regularly. By contrast, a recent survey of electric bicycle owners reveals that 33% ride their bike at least once a day and 81% use the bike at least once a week. The figures confirm our experience that an electric bike typically gets used much more often than a conventional bike. 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 majority have 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 transferring a bit more load to the electric motor. In colder weather - or if you feel in need of exercise educe the level of assistance, or you can even turn the motor off. 
 
5. Faster travel 
In theory a car can travel at high speed, but in practice speed often falls below 10 mph in cities. The problem is congestion - motorcycles get around this to some extent, but they're still confined 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 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 hills and headwinds, electric bikes are often the most consistent mode of travel. 
6. Motorise, but no 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! 
 
7. Clean and green 
Electric bikes obviously consume energy, where a conventional bike 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 the 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 travelling much faster). In terms of fuel consumption, an electric bike achieves about 800-2,000 mpg. 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.... 
 
 

Are electric bikes 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, and the vehicle's fossil fuel consumption will be zero. Surely a conventional bike does that already? Only if 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 terribly good.
