In the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. Electric Bike Motor An electric bike motor on an electric bike can be any kind of electric motor. There have been some very creative home brew e bikes that used any motor...
One of the biggest drawbacks to any ebike is its range — and perhaps to a larger extent, the capacity of its compatible battery. Since battery technology innovation is fairly stagnant, the German ebike company Riese and Muller decided that instead of making a bigger battery, it’d just slap a second one onto its latest release, the Delite nuvinci. Though the attachment does add more to the final price (to the tune of $823), it also increases the Delite nuvinci’s range to a whopping 130 miles — which is leaps and bounds further than any other ebike on this list.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...

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]
Powered by a 250-watt Brose Centerdrive system, the Redux is capable of reaching speeds of up to 28 mph, which comes in handy when dodging traffic. Its 36-volt lithium-ion battery provides enough juice to give the bike a range of up to 80 miles between recharges, making it a great option for daily commuters. Raleigh even outfitted the bike with wide tires which provide stability and traction, even when the road gets wet. Other key features include a 10-speed Shimano crankset and shifters and a built-in LCD screen that displays all the usual information.

The features continue with integrated lights and a minimalist display set into the top tube that relays charge, speed and level of assist. The most exciting aspect to the Vanmoof though is a setting on the app that allows you to toggle your bike’s speed limit between European 25kph and more generous (but not entirely legal) 30kph United States limit. That cheeky extra 5kph is enough to make the Vanmoof the bike for city riding at pace. The S also features a Turbo Boost button (that puts the motor at full assist), which was a welcome bonus nipping across busy intersections or powering out of a tight corner where your speed has dropped.
The first step in deciding which Electric Bike is for you is to determine the right style of bike. We have a full range of styles, including, Mountain Electric Bikes, Comfort E-bikes, Commuting E-bikes, Fat Tire Ebikes and even folding bikes. From their, you'll choose the motor size. We offer motor sizes from 100 Watts all the way up to 6000 Watts!
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.
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.

Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[44][45] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]
On the road, it takes only a few turns of the pedals to activate the Vado’s motor and get it up to speed. In Turbo mode — the bike’s highest level of pedal-assist — the Vado reaches speeds of up to 28 miles per hour, after which the electric drive system automatically shuts off to conserve power (and abide by local law). A built-in LED readout on the handlebars allows riders to monitor battery life, check current speed, and track calories burned while also being able to glance at distance traveled. The Turbo Vado Mission Control app (iOS/Android) also connects to the bike via Bluetooth and allows riders to further tune their ride and adjust the bike’s settings.
China's experience, as the leading e-bike world market, has raised concerns about road traffic safety and several cities have considered banning them from bicycle lanes.[2] As the number of e-bikes increased and more powerful motors are used, capable of reaching up to 30 miles per hour (48 km/h), the number of traffic accidents have risen significantly in China. E-bike riders are more likely than a car driver to be killed or injured in a collision, and because e-bikers use conventional bicycle lanes they mix with slower-moving bicycles and pedestrians, increasing the risk of traffic collisions.[2]
Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.
Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.

You turn it on by pressing the green button on the battery once for low power and twice for high, although to be honest, there is not a lot of difference between them. After that, you just pedal. There are no gears, no chain to muck up your trousers (a motorbike-style carbon fibre belt is used instead) and not that much difference in feeling compared to riding a normal bike.
What we especially love is how quiet this e bicycle is. If you’re riding down the street or through the park, the gentle hum of the motor is unnoticeable. This is because it’s hidden by the sound of your smooth pedaling. If you’re not into flashy gadgets, any ordinary person would assume you’re riding a conventional peddle bike. This is a great commuter bike.

For those looking to hit the trails instead of the pavement, Yamaha has you covered with their new YDX-TORC electric-assist bicycle, which is powered by a souped-up version of their mid drive known as the Yamaha PW-X center drive motor system, which the company claims offers the extra power needed for more adventure and exploration on the trails, including a fifth power assist setting. As a more powerful e-bike, the YDX-TORC also demands a higher price of $3,499.
The environmental credentials of e-bikes, and electric / human powered hybrids generally, have led some municipal authorities to use them, such as Little Rock, Arkansas with their Wavecrest electric power-assisted bicycles or Cloverdale, California police with Zap e-bikes. China’s e-bike manufacturers, such as Xinri, are now partnering with universities in a bid to improve their technology in line with international environmental standards, backed by the Chinese government who is keen to improve the export potential of the Chinese manufactured e-bikes.[67]
Folding Electric Bikes- These are mostly used when people need to combine different modes of transport. For example, if you need first to take the train or bus, a folding e-bike can be useful to carry along. Also, very short trips are more convenient with these electric bikes since you don’t need to bother tying them up. Typically, these are very light, even with the motor and battery.
Unlike most e-bikes, the Brompton's battery is integrated into a bag that sits on the front of the bike. While that detracts slightly from the classic, streamlined design, it's handy as it can be unclipped for charging or riding as a regular bike – it's probably one of the easiest to ride without battery assistance thanks to its weight. The battery also powers two lights for safe commuting.

What a treat to do business with the folks at Hill Topper. I now have two commuter units one in Idaho and one in Denver my average ride is 25 to 35 miles. I have been riding for about 15 years but being the age of 80 I needed a little help the past few years. I researched electric bikes a few years ago even rode a couple here in Denver but I wanted my own personal look and feel. So about five years ago I found Hill Toppers. What a treat first the units are the best but that is part of the good part the people at Hill Toppers are the very best to work with and enjoy. I had to have a knee replacement last July well thank god for my bike it was the best therapy I could ask for. When in Idaho I get to ride along the Snake river what a treat knowing that I have this unit to help if the wind or rain shows up. When in Denver I cover a lot of area as they have wonderful bike trails all over the area. I ride all of the downtown area and the Cherry Creek dam up and over it takes some effort to get that done but with the help of Hill topper it is a beautiful ride up and overlooking the whole of Colorado. Thank you Andrew,Charles,Sam,Mark.
Have to give a shout out to a Bulls Brose option. They were the first manufacturers I saw integrate the battery into the frame really well, and they’ve continued to improve upon that design. As I mentioned above, I love the wave frame. Super easy to get on and off and it’s got a cool look as well. If you’re not a fan, this bike does come in both a Diamond and step-thru frame.
For an overview of Stark Drive Electric Bike, its features and our story click above. Our passion for biking and our determination to take electric bikes mainstream have driven us to create the world’s most affordable electric bike. As technology improves, so will Stark Drive with the caveat that we will always offer the most affordable electric bikes in the world.
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
