The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is a highly unusual approach –  drawing power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever.

By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]
The motor on the Patriot DreamE drives the chain and utilizes the gearing of the bike for remarkable power and speed. If you want more speed or hill climbing power, simply change the rear cassette. The motor is lightweight and mounted low on the frame for better balance. Unlike hub motors, this frame mounted motor allows you to remove wheels (e.g. to fix a flat) like a traditional bicycle - without any wires to disconnect and reconnect.

Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.

The Soho is one of Coboc’s four single-speed pedal-assist bikes. The bikes are differentiated with finishing kit - handlebar style, bar-tape, saddle and paint finish. With a retro / bespoke styling with Bullhorn bars, Brooks fabric-tape and Cambium saddle and brushed aluminium frame, the Coboc is an e-bike for riders who don’t want to look like they’re riding an e-bike. The ONE Soho is for a rider that doesn’t want gears either.
From the tropics to the polar caps, Stark Drive is designed to handle a broad range of temperature conditions with a ruggedized frame and high quality battery pack as well as all terrain tires (standard) or even our fat tire model. Take Stark Drive with you wherever you go. When Designing Stark Drive in Stockholm Sweden we were very conscious of the fact that weather effects battery life on your electric bike so we designed our electric bike with this in mind.
The downside to this mountain-bike build and specification is obviously the weight, at 24.5kg the Trekking feels heavier than the other bikes on test, and rightly bills itself as suitable for heavier riders, too. As with the other bikes here, this is only really a problem for smaller riders, or riders needing to take the bike up or down steps regularly. With its bomb-proof build, full guards and heavy-duty rack, the Haibike is the perfect choice for a burly rider or for doomsday preppers, ready to out ride the apocalypse.
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). 
The other thing to consider is that this is a Kickstarter project, so you aren’t directly purchasing from the company, but rather “backing the project” in exchange for a bike. Technically, Stark Drive, or any Kickstarter creator, could cut and run with the money, leaving their backers without legal recourse. In this case though, Stark Drive has already run a successful crowdfunding campaign for their previous bike and demonstrated their ability to deliver, so this is probably at least somewhat safer than a brand new Kickstarter start-up.
Others questioned the weight. The Indiegogo campaign claims the steel-framed e-bike weighs just 45 pounds complete, but that’s highly unlikely, says Court Rye, owner of the Electric Bike Review website. He’s posted an 18-minute YouTube video of his thoughts about the Storm eBike that he says tries to strike a balance of appreciation for the low price point and realistic expectations.
The Dash is an excellent, low-cost option for those looking for an intro to e-bikes kind of ride. The TranzX motor will take you up to 28mph for about 16-35 miles per charge–more if you’re conservative with the assist. The components aren’t too shabby either. Shimano M365 hydraulic disc brakes keep you safe, the Shimano Deore SGS drivetrain, and RockShox Paragon fork with 65mm of travel make it a great entry level option.

BULLS never ceases to amaze. This full-suspension fat bike is fitted with a Bosch mid-drive motor for enhanced hill climbing. The 4-inch wide Schwalbe Jumbo Jim Snakeskin tires are genuinely monstrous. It's exquisitely designed and equipped with all the best components. As with all BULLS ebikes, the Monster E FS comes with a 2-year warranty and 5-years on the frame.
Thanks to clever engineering, the Electric Brompton folds up identically to the non-powered variety. It is heavier than a standard Brompton of course, but quite light by e-bike standards. It has small , suitcase-style additional wheels that come into play once folded up, and the way the weight is balanced means it is quite straightforward to trundle along in that state.  
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.
