While the first electric bicycle was invented way back in the 1890s, historically e-bikes have struggled to gain momentum, only breaking into the market in mainland Europe at the turn of the 21st century. E-bikes now account for 38.5pc of all bicycles sales in Germany (Holland and France and also big players); belatedly, the trend is starting to register in the UK. Battery assisted bikes now make up around a third of bike sales at Evans Cycles West End.
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.
