All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for  town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.

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.
The Nuvinci hub system is the best geared hub that I have ever used. There is literally no maintenance to be done on this drivetrain. I’d recommend buying it with the Gates Carbon belt because you’ll never run into issues like the chain falling off. You operate the Nuvinci system with a grip shifter and can of course shift even when you’re not moving.

Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]

A Kalkhoff Pedelec is a lot more than simply bolting a motor onto a great bike. Their electric-assist bicycles utilize a brushless DC motor system that is lightweight, precisely-controlled, efficient, low-maintenance, and reliable. The Panasonic drive system is center drive, meaning that it's designed to be in the middle of the bike for a low center of gravity, stability and an easy integration with the drivetrain. The drive unit is more than just a motor; it also has a torque sensor and controller unit as well - all in the weatherproof casing, surrounding the motor. The torque sensor and the controller senses how hard you're pedaling and adjusts how much assistance the motor gives you through the drive sprocket.


We rode the Vado through the gauntlet, including some of the steepest hills in Palo Alto, and it easily handled everything we threw at it, maintaining a steady 20 miles per hour even on the most daunting of ascents. The bike also handles well on downhills and is both nimble and quick on city streets and paved trails. It’s even comfortable to ride for extended distances, which is vitally important for any bike built for urban settings.
It will be of little surprise to learn that the Hanebrink all-terrain vehicle was designed by six time Mountain Bike national class champion and former U.S. National Team member Dan Hanebrink. It's based on 1993's Extreme Terrain fat tire pedal bike and is made to order at the Fortune Hanebrink workshop at Big Bear Lake, California. Echoing the philosophy of many electric assist bicycle makers, Hanebrink says: "We are not trying to replace standard bicycles, we want to replace cars and trucks."
The Super Commuter is very aptly named. The 350w Bosch motor will help you sustain speeds of up to 28mph, and the burly, 2.4-inch wide, Schwalbe Super Moto-X 650b tires will keep you secure on even the roughest city streets, and Shimano Deore hydraulic brakes provide ample stopping power. Fenders provide welcome protection from road spray so you arrive at your destination fresh, integrated lights are critical for post-sunset riding, and a side-view mirror hanging on the left side of the handlebar gives a great view of traffic around you. After all, you can ride at the speed of urban traffic on the Super Commuter.
All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
But this bike isn’t just about the accessories. The powerful 48V 13Ah battery will allow you to pedal for longer, with some riders getting over 100 miles from one charge. The bike can be ridden as pedal-assist or throttle only and it’s equipped with full suspension and puncture-free Kenda tires. It folds up neatly to fit into the boot of a car or for commuting, though at 57 pounds, it’s heavy to cart around. A great value-for-money commuting bike with lots of features.

Standard front suspension is the 7” conventional single crown forks. With 2 dials to adjust compression and rebound adjustment and air adjustment for preload, these forks are light weight and versatile enough for most situations. For heavier or more adventurous riders, the forks can be upgraded. The rear suspension is adjustable for casual every day riding or more aggressive off road environments.
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
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.
Out on the road the Soho is easy to fire up, just press the button hidden under the top tube (a nice discreet touch), you’ll then get a set of five top-tube mounted LED’s light up to give you a charge indication. First impressions were that the engagement of the motor is a little jerky in tight traffic (tested in central London) and you could find yourself pulled toward the cars you’re weaving though at slow speeds - unless you’re feathering the brakes.
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
Twice the speed - with half the effort, Optibike has the power. On a test ride in Boulder Colorado, a fit road cyclist was able to climb the notorious Old Stage Road at 10 MPH sitting down with an easy spin on the Optibike. On his ultra light road bike, he had to stand and grind all the way to go 5 mph!!! Twice the speed - half the effort, Optibike has the power.
Once you accept that you are really meant to pedal gently and let the motor do the work, non-speed freaks will get into it. E-bikes are great for commuting and for places that aren't pancake flat. They'll pull you away from the lights quickly, iron out hills and stop you getting sweaty, so you can bin the Lycra and ride in jeans, a suit, or, I dunno, an inflatable sumo wrestler costume. Whatever you like.

Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres.[51][52] Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.[53][54]
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 Dail-E Grinder is perfectly designed to accompany you on your long commute. It's a top-of-the-line road bike in and of itself. BULLS has taken its premium frame and integrated it with the most advanced components from best names in the business.  It delivers an unbelievable 118 miles range under ideal conditions. This step-over speed-pedelec is a wonder of German engineering.

Electric Motor. Having a battery that will last long is just one piece of the puzzle. The electric motor should be powerful enough to move the bike on flat surfaces without any problems and to overcome some low-steep slopes. It will help you out on steeper slopes, it won’t let you down. If the motor or “the engine” is more powerful you’ll be able to accelerate faster and to reach a higher momentum. This will allow you to reach your destination faster and without you getting tired.

The Nobby Nic tires would work equally well on road, loose dirt, gravel, fire roads, or anything of the like really. The hardtail geometry also isn’t so aggressive that it would be uncomfortable over long distances. Of course, comfort over long distances is key during bike touring. Even though the bike does not come with a rear rack, it does have eyelets for mounting. A rear rack should allow you to carry plenty for a 3-5 day excursion.

Their electric-assist bicycles utilize a brushless DC motor system that is lightweight, precisely-controlled, efficient, low-maintenance, and reliable.

The torque sensor and the controller senses how hard you're pedaling and adjusts how much assistance the motor gives you through the drive sprocket.

Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.

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. 

Bicycles featuring pedal power were developed during the subsequent decades of the 19th century, with the most emblematic example being the bicycle we know today as the Penny-Farthing. The bike was named based on the substantial difference in its wheel size resembling the larger and smaller Penny and Farthing coins, respectively. These bicycles were wildly popular among the well heeled upper classes of Europe and America despite their penchant for launching riders head first over the large wheel, not to mention their relative difficulty to mount and dismount.
Electric mountain bikes have garnered a lot of attention for their ability to help riders go higher, further, and faster on the trail. As a result, there have been some impressive new eMTB models to hit the market in recent years, making it easier than ever to head off-road. Our favorite is the Haibike SDURO HardNine, which comes equipped with a 350-watt Bosch Performance CX drive and a 500 watt-hour battery. This gives it a range of up to 70 miles, along with a top speed of 20 mph, which is plenty fast on singletrack.
It really is a simple e-bike, and while I could go on about the frame (aluminium), and the weight (very light), the experience of using this bike for a few days is more interesting. While it feels like a less high-tech product than others in this list (no gears; a shorter battery life of 30 miles; two modes not three), it basically retails at half the price as those competitors – and I certainly didn't find it to be half as good.
In addition, Kalk weighs under 155 pounds — less than half of traditional motorbikes. Cake customized parts of the drivetrain and implemented an interior permanent magnet (IPM) motor. On a single charge, the bike travels up to 50 miles and as a bonus feature, maintenance is minimal due to the fact there are few moving parts thanks to its lack of a combustion engine.

Riding a pedal-assisted road bike may seem counterintuitive but during longer training sessions, the minimal addition of power helps prevent overall muscle fatigue and injury. Similarly, those looking to enjoy longer scenic routes will appreciate the general boost an electric drive provides. With a top speed of 28 mph, the Road E+1 uses three power modes to give you ultimate control over your ride and assistance level. A four-point sensory system monitors the pedaling force allowing the motor to amplify your movements seamlessly.
The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
