In Brief
Wisper SE bikes have a cadence (otherwise known as speed) sensor
Wisper Torque bikes have both cadence and torque sensors
Cadence/Speed Sensors
Cadence sensors turn the power on when pedals are turned forward and turn the power off when pedaling stops.
It will take between ¼ and ½ of a complete revolution of the pedals before the power is turned on.
Torque Sensors
Torque sensors recognise when and how much pressure is being put onto either pedal. Power will increase as the pressure on the pedals increases.
Power is available immediately pressure is put onto either pedal.
On Wisper Torque bikes the torque sensor will be deactivated and the cadence sensor will activate when the bike is put into F power mode on the LCD.
The Operation of Wisper SE (Cadence sensor) and Wisper Torque sensor Bikes
Wisper SE
The magnetic disc can be seen on the SE bike, it is a part of the cadence sensor and sits on the inside of the right hand crank by the bottom bracket axle. It simply tells the bike when the pedals are being turned forward at which point the power switches on. When a rider stops pedaling, the magnets stop passing the sensor and the power turns off.
Wisper SE bikes require three magnets to pass the sensor in the correct order (pedals turning forward) before the power is switched on, it then needs magnets to pass by the sensor in quick succession or the power will turn off again. If the pedals stop turning, the bike will recognise this in a small fraction of a second and the power will turn off, hence the reason we do not need vulnerable brake cut outs.
Wisper Torque
On Wisper Torque bikes the torque and cadence sensors are housed inside the bottom bracket where the pedals are connected through the bike frame.
The Wisper Torque system works in a completely different manner to the Wisper SE. Through the torque sensor the system measures the pressure a rider is putting onto the pedals. Pressure on the pedals turns the power on and the torque sensor reads the amount of pressure being exerted. The more pressure a rider puts onto the pedals the more power will be demanded from the motor.
So… if the bike is starting from standstill, encounters a hill, a strong headwind or if the bike is heavily laden, the torque sensor will recognise that more pressure is being put onto the pedals and the bike will offer more powered assistance. It’s very simple and very clever!
Either the left or right pedal will activate the torque sensor.
The torque sensor works in levels 1 – 4 on the handlebar LCD. If you turn the bike onto F, the torque sensor is deactivated and the bike works on cadence sensor alone. The F setting should only used when a rider is on a flat road and needs extra assistance. On a flat road, the rider puts very little pressure onto the pedals, the “torque” sensor recognises this and the bike conserves energy, hence the longer range by up to 40%. So on the flat, should the rider need more assistance they can turn off the torque sensor buy switching to F for FLAT.
The Throttle
Both Wisper SE and Wisper Torque bikes have a “twist and go” throttle as a part of the left hand grip.
The throttle is set up to comply with European law, where it is only used for assistance when walking the bike.
HOWEVER….. If a rider twists the throttle and holds it open whilst riding either the SE or Torque bike (pedals turning forward) the throttle will override all the sensors and offer “assistance” up to a maximum speed of 15.5mph regardless of the amount of pressure being exerted on the pedals.
The new Wisper Hybrid Torque drive system is designed to deliver maximum power to the bike’s rear wheel smoothly, quietly and efficiently.
The new Wisper Hi Torque Motor is so small, it is hardly noticeable behind the rear gear set.
Click on the > to the right of the headings below for more information.
The new Wisper Hybrid sensor cleverly splices information from the torque and cadence sensors, producing a seamless riding experience. Our patented software enables the controller, sensors and motor work together in perfect harmony, creating a seamless delivery of power.
The increased efficiency of the system means a rider can achieve up to 40% more range when compared to a cadence sensor alone.
The combination of information from the two sensors coupled with the amazingly fast processing of data, ensures the new Wisper power system rapidly responds, to the speed of the bike and the rider’s input, and riding style, creating a very natural riding experience.
The benefit of the Wisper Torque sensor can most be felt when setting off, especially on an incline. The software in the controller will recognise that the bike is stationary, so when the pedals are pushed down the bike will know the rider needs maximum assistance to get them going. It very much feels as if you have twisted a throttle. When the bike gets moving the cadence sensor recognises you are on the move so will gradually reduce the power. The rider will not feel the gradual reduction, the whole experience will feel very natural.
New sine wave technology coupled with the rear wheel drive, has the effect of making the new Wisper Torque system virtually silent despite it’s superb hill climbing capability.
Being positioned behind the rider any running noise from the motor becomes practically inaudible.
The system starts and stops within milliseconds of putting pressure on, or taking pressure off the pedals. This almost instant reaction has two major advantages:
Starting off on, and climbing steep hills becomes much easier. Maximum power is available immediately depending on how much pressure is exerted on the pedal, negating the need for a throttle.
Maintaining and controlling speed is far less erratic, ensuring the riding experience is safer and more natural.
The four major benefits of the Wisper Torque rear hub system over centre drive systems are as follows:
Power is directly and efficiently applied to the rear wheel. This eliminates issues associated with chain stretch/wear and putting too much torque through delicate hub or derailleur gears.
Companies such as <strong>Shimano</strong> do not recommend that more than 35Nm of electronic power is put through their systems.
Our rear wheel direct drive hub system avoids the bicycle chain and gears, therefore, the whole 50Nm of available power can be directly applied through the rear wheel.
Positioning the motor and battery at the rear of the bike keeps the weight directly over the rear tyre ensuring a more positive grip, especially in wet or slippery conditions.
Firstly the 575Wh battery will give you nearly 50% more range than the 375Wh battery and the maximum power band is almost twice as long, helping you climb those steep hills.
The latest Wisper 575Wh Samsung batteries are installed with the very latest battery technology. These state of the art batteries have advanced soft ware that automatically assists in keeping a battery in perfect condition.
A 575Wh battery will on average last one and a half to two times as long as the 375Wh battery. This is due to the stress levels put on the battery being much lower on the larger battery.
We guarantee our batteries will not lose more than 30% of it’s capacity within two years of purchase. Consider that when a 575Wh battery has lost 30% of it’s capacity you still have a battery with a 400Wh, this will still offer assistance for longer than a brand new 375Wh battery.
In the long run a 575Wh battery is always cheaper.
The critical point regarding battery longevity is that the battery is topped up regularly and and never left flat for more than a few hours.
Wisper bikes are powered by high quality lithium ion batteries.
To achieve maximum battery life, it is important that a lithium battery is correctly maintained. All lithium batteries gradually lose capacity and therefore reduce the range of an electric bike. If well maintained a high quality lithium battery will give several years and thousands of miles of good reliable service.

Recharge your battery after every use if possible
Keeping a battery charged extends it’s life and ensures your Wisper bike is always ready to go.
You no longer need to “condition” your battery by fully charging and discharging before it’s first use
This used to be the case with old lithium ion technology but is not necessary with modern batteries.
Never leave a lithium battery completely discharged for more than 12 hours
Lithium batteries should be recharged every six weeks even if it is not being used
Most lithium batteries will continue to discharge even when the bike and battery are turned off. Our 575Wh super long range battery can be safely left for six months when fully charged.
Voltage falling bellow minimum is by far the most common reason for lithium battery failure. This is particularly noticeable in the spring when customers are using their bike for the first time in the new year after a period of non use.
Never leave a lithium battery connected to a charger or mains power over night.
Never recharge a battery outside, in damp conditions or in temperatures of less then 0 degrees centigrade.
Never open a Wisper battery case, try and maintain the battery or give it to any person or organisation other than a registered Wisper Stockist for maintenance. (Failure to comply will void your warranty)
Never use a lithium battery if it seems to be damaged.
The latest Wisper long range batteries are equipped with features to help keep it in good health.
“Deep sleep” or “hibernation” mode.
Once a Wisper 575Wh battery has been fully charged it is not necessary to recharge again for several months, for example, over the winter. We recommend the battery is recharged every 6 months, however with a full charge it will be safe for up to a year. To manually put the battery into deep sleep mode simply press the LED button on the rear of the battery for 10 seconds. If the battery is not manually put into deep sleep mode and the battery falls below 29V, deep sleep will be activated automatically after 24 hours of non-use. The battery will automatically wake up when connected to a Wisper bike and the bike is switched on.
Wisper 575Wh batteries are delivered to Wisper stockists in deep sleep mode, so they arrive with our customers as fresh as when they left the factory, ensuring the longest possible life.
Phone Charger
The socket on the battery can be used to charge a mobile phone.
General Maintenance
Like any bicycle, it is important that your Wisper Electric Bicycle is kept clean and well lubricated. Our ebikes fall into the City and Trekking category and are not designed as mountain bikes. If you do use your Wisper bike in “off road” conditions, it is important that all mud and sand is cleaned from all moving parts and the parts are lightly lubricated, before storage or further use. Making sure no lubrication is applied to braking surfaces. A build up of mud and/or sand on moving parts will damage your bike and may negate the warranty.
Regular Servicing
All bicycles need regular servicing and electric bicycles in particular should be serviced and checked over by an electric bike specialist at least once a year. If you are using the bicycle on a daily basis, for your safety and for the correct levels of maintenance, we recommend six monthly servicing. Your local Wisper Service Centre will be happy to help you look after your bike.

Are throttles legal in the UK?
Throttles are legal under the following criteria.
Can I ride my ebike on cycle-paths?
You can ride your electric bicycle anywhere a normal bicycle can be ridden, this includes cycle-paths and bridle ways
What is the top speed of an ebike?
The speed limit for an electric bicycle is the same as for a normal bicycle or any other motor vehicle. The assistance on an electric bike must cut off over 15.5mph
Do I need a driving license?
No, as long as you are over the age of 14 you can ride an electric bicycle without a licence
Can I legally ride my ebike anywhere in Europe?
Yes, however it is always advisable to check the local traffic laws in the country you intend visiting
What’s the difference between crank drive and hub drive?
A crank drive or central motor drives the pedals and a hub motor drives the wheels directly. A hub drive is more efficient and does not damage the chain and gears but is sometimes considered better when climbing very steep hills or pulling very heavy loads.
What are the benefits of riding an ebike?
There are many benefits including the following:
Is it safe to cary an ebike on a car rack?
Yes certainly, however always make certain the rack you are using is built to take the heavier weight of your bike compared to no ebikes. We advise you take off the battery and make sure the electrical parts are protected from the weather.
How much does it cost to own and run an ebike?
A good electric bike can be as inexpensive as £1,099.00 and will last for many years. Including maintenance at a local dealer we would expect a bike to cost in the region of £35.00 a month to run over the corse of five years.
How should I maintain my ebike?
We recommend that you take your ebike to your local Wisper dealer to be serviced twice a year, depending on usage. You should top up your battery as often as you can to keep a “full tank”. Before every ride check the brakes and lights are working well and that there is no visible damage to the bike, tyres or battery. It is important that you keep your bike clean and lightly lubricate the moving parts least once a month making sure you do not get lube on any of the braking surfaces.
What happens if my ebike gets wet?
Your ebike is designed to work perfectly well in the rain and drizzle. The electronic parts should never be submerged and it’s best to keep your bike and battery in a dry place when not being used. If your bike gets particularly wet, we advise quickly drying it off before storage.
