Having never ridden one before, I took a few electric bikes out to review in Central London and was an instant convert. For a commuter, they're ideal. While you still feel you've done exercise, the assistance means you won't arrive at work in a hot and sweaty state. The power boost whenever you start from a standing position is ideal for a speedy getaway at a traffic light with buses and lorries right behind you. And you'll get a nice ego boost every time you effortlessly ride past a struggling regular cyclist.

Using an electric bike for long-distance touring has its pros and cons. The motor will help carry the extra weight of your kit, particularly on the hills, but you have the added hassle of having to charge the battery every night. You’ll want a powerful motor and a good battery, though if you’re fully loaded, don’t expect to achieve the maximum advertised range.
One of the biggest misconceptions about e-bikes is that you're not actually doing any work when you ride one. Not true. Thanks to that battery-powered motor, E-bikes are heavy! So if you turn the assist mode to low or off, you're still putting in plenty of effort. Many commuters have found that traveling home from work with assist off (when they're not in as big of a rush and don't mind getting sweaty) is a great way to fit exercise into a busy schedule.

After suffering a back injury and returning home as a disabled combat veteran, Chris found himself unable to exercise the way he had in the past. It was particularly discouraging to be kept from riding his beloved bicycles. Rather than dwell on his misfortune, he decided to search for viable alternatives. It wasn’t long before he settled on his first electric-assisted bike. His passion for bicycles was reinvigorated and he realized he had to share it with the world.
Yes, you read that right – north of £4k for a bike. But then, this is basically the top end of the mountain e-bike market, and you do get a lot of bike for your buck: a Yamaha Lithium battery, masterful Magura brakes, mud-slaying tyres, and – my favourite flourish of all – a hydraulic seat post that you can adjust on the move (surprisingly useful when navigating tricky downhill trails, as it means you can depress the saddle out of the way with the press of a button). 
FRAME GEOMETRY  EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability.  The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike.  Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride. 
For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
