Professional Opinion

Electric bikes are just like standard bikes, but far easier to ride thanks to the addition of a motor to assist your progress.

Electric bikes are making personal travel that little bit more enjoyable for everyone, with e-bikes becoming a common sight on Britain's streets.

E-bikes have seen a major image and quality revamp over the last few years, which has seen user numbers sore over the past few years and are still increasingly growing year on year, with no less than 60,000 e-bikes sold each year here in the UK.

With the soaring cost of living at the moment, an electric bike can be the perfect tool to reduce your daily costs.

You'll save money on petrol - In fact, the majority of journeys (71% in England) made are under five miles. But cycling only accounts for less than 2% of all journeys. Imagine the money we could save if we switched those short drives to pick up a few items at the shops or dropping the kids off at school to a bike.

Less car maintenance will be required

You'll still get exercise – e-cycling is not cheating! Many studies have shown that e-bikers get plenty of very beneficial aerobic exercise. The vast majority of e-bikes have power level settings on the handlebar controls that let you dial down the power if you want more exercise or turn it up if in need of more assistance.

You're helping the planet by cutting down on less emissions.

They are great fun to ride!

Just like a standard bike, electric bikes come in a variety of styles, from folding bikes to off-road mountain bike machines, here at Cycle King we have something to suit everyone's needs.
