Electric bicycles or pedelecs are already mainstream and a growing number of people are attracted by this hassle-free means of personal transport.

Most good bike shops are offering a growing range of e-bikes alongside their pedal-powered cousins and as the selection on offer gets bigger, sales in this segment are ballooning.

The story is the same in many countries, like, for example, Germany where a large rise in e-bike sales in the space of just a year saw a total of 720,000 e-bikes bought in 2017 – an increase of 19% over the year before.

One of the main reasons for the sales is the choice of e-bikes in the shops and there's the rub. Before consumers can choose the right model

Answering this one correctly is the key to becoming a happy e-bike owner – “When buying an e-bike you really want to be clear about the type of bike you want,” says René Filippek of Germany's huge ADFC cycling club.

An electric version of the classic commuter bike with 28-inch wheels and a sporty riding position is a good compromise. It can not be away from the tarmac. The same applies to pure road bikes which combine aerodynamic efficiency with the effortless power of a pedelec drive unit

Foldable e-bikes are small in stature which makes them ideal for commuters who might want to combine them with a bus or rail journey.

Most pedelecs will travel up to 25 km / h before the motor cuts out to comply with legal requirements. This makes them around 10 km / h faster than a regular pushbike. Speed ​​pedelecs are high-powered e-bikes. They are as fast as 45 km / h. These are banned from cycle paths and must be fitted with registration plates. Owners need to wear a helmet too.

Batteries and charging

The battery is a key component of an electrically-assisted bike and most come fitted with a unit rated at 400w or watt-hours. This means the battery provides 400 watts of power for one hour.

Fillipek says this provides a range between charges of 60 and 80 kilometres, although the distance will depend on the type of bike and even weather conditions. it is cold outside.

A higher wattage up to 550w gives more range but such batteries are much more expensive to buy and replace. Most batteries are detachable which makes them easy to charge at home using mains electricity. Full replenishment usually takes up to five hours.

Replacement batteries are expensive but in most cases the power pack will have a guarantee of at least five years. A battery will tend to have a usable life of 1,000 full discharge-recharge cycles.

The motor

Some pedelecs have the motor at the rear hub but most will have the same power . This gives a good center of gravity and aids stability.

A typical motor from Germany's Bosch will be for many years with little attention or maintenance. The motor is encased in plastic and is waterproof.

Changing gears and operation

Wear on chains, rear cassettes and gear-change parts is higher, this is having to take the extra strain from the motor. 19659001] Many Pedelecs have conventional derailleur or hub gears from makers like Shimano or Sram apart from upmarket models which use more sophisticated belt drive systems from Continental or NuVinci.

By the way, conversion kits to convert a push-bike to an e -bike are not recommended. In most cases, a conventional bicycle frame is not strong enough to cope with the extra weight.

Most e-bikes offer three levels of electric assistance from Eco to High. The lowest setting is for flat terrain and assistance is between 25 and 80% of maximum battery power. Running in Eco will save battery power but can still be hard work uphill.

The recommended default setting is Normal or Tour. For steep hills a burst of High mode should take the sting out of gradients. Naturally, using more power will dent range.

Take a test ride

Nobody should buy an e-bike without a lengthy test ride, especially if a potential buyer is not used to rapid riding. An e-bike travels faster than a pedal-powered equivalent. The brakes are more powerful and take some getting used to.

Cyclists should also keep away from cheap e-bikes which are often just not up to the job. An e-bike must have a robust frame, good brakes, and a motor manufacturer.

Expect to pay between US $ 1,800 to US $ 3,000 (RM7,111 to RM11,851) for an electric bike and even only if it is technically more complex. – dpa
