An electric-assisted bicycle is a regular bicycle with a small auxiliary motor and battery attached. The standard definition of power assist bicycles only applies to vehicles that can be propelled by human power alone:
“it is equipped with an auxiliary driving motor having a maximum continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the vehicle reaches a speed of 25 km/h”.
The more general term ‘electric bike’ or ‘e-bike’ applies to any kind of bicycle with electric assistance of about 250Watts. These bikes are legally classified as bicycles because they have pedal assistance and go up to 25km/h.
They are great for commuters, particularly people with hills to climb, and can provide a much-needed boost in some cases. The benefits of the electric bicycle are the same as those for motorcycles: more power on steep or long routes, less effort while climbing or going downhill, less fatigue on longer rides, etc.
A new kind of cycling that takes place in some cities is using an e-bike to carry loads such as groceries and other shopping items. This bicycle has a specially modified frame that allows a second person to sit on it while carrying large objects.
A personal transporter consisting of two small wheels connected by pedals with an electric motor providing assistance when necessary – this is what most think about when they hear the term “electric bike”.
These bikes are also called power-assisted bicycles. They are very popular in Asian countries where they are widely used as a convenient way of getting around cities.
With the rising cost of fuel, electric cycles have become more affordable for both commuters and travelers.
The definition of an e-bike is quite loose with many items being classified as one even if they should fall under other definitions.
For example, ‘pedelec’ power bikes provide assistance only when the rider is pedaling but start off at low speeds which fall under the definition of a moped or motorcycle rather than that of a bicycle!
Similarly, under many jurisdictions, there are legal restrictions that severely limit people to using e-bikes on cycle paths or trails specifically made for bicycles.
The most important thing that distinguishes a traditional bicycle from an e-bike is the motor.
An e-bike usually has a brushless electric hub motor built into its rear wheel – you can occasionally see these on some mountain bikes too.
Benefits of an Electric Motor
The advantages of having the motor in the wheel as opposed to at the crank or bottom bracket are several.
Firstly, there is no chain which reduces maintenance and increases drivetrain efficiency.
Secondly, the weight of the bike is more centralized on its axle which takes the strain off your hands and wrists on long rides.
Thirdly by distributing power through 3 points (pedal cranks, bottom bracket axle, and rear-wheel via a differential) instead of one (crank) you achieve greater torque at the rear wheel.
For example, when starting off or climbing steep hills you can pedal harder while using the throttle at the same time which provides more power than just pedaling alone.
Another great feature of hub motors is that they are nearly silent, although some newer models have different sounds to alert pedestrians! Furthermore, if you use your bike for commuting or errands you don’t need to worry about running out of juice because the motor only comes on when it’s needed – this makes e-bikes truly practical!
E-bike motors come in many shapes and sizes depending on their voltage, amps, and watts (measured in RPM/V x A x P = WATTS). A common misconception with people who aren’t familiar with them is that more power equals a faster bike.
This is not true; it simply means the motor has to spin faster to reach the desired speed which will consume your battery power much quicker! Therefore when choosing an e-bike you need to think about how much power you actually need.
A 250Watt (0.25kW) hub motor helps cyclists who are struggling on long rides, especially if they’re carrying excess weight, but 20kW+ motors are used for racing purposes only!
There are no particular rules or laws governing what they have to look like! They can be the same size and shape as a regular bike, a bit bigger, a lot bigger or in some cases even smaller!
For example the popular ES model from Tern weighs just 35lbs (16kgs) yet has an integrated lithium ion 36V 10.4Ah battery that provides up to 70 miles per charge with peaks at 20mph (32kmh)!
In comparison the much bulkier M1 model from eZee is equipped with a rear mounted hub motor and built-in lead acid batteries which weigh over 100lbs (45kgs).
It’s practically the same size as a regular bicycle but comes stock with dual suspension, regenerative braking and belt drive transmission – it also provides 80 miles even though it’s twice the weight!
Electric bike batteries can also vary greatly – some have removable batteries which you charge at home or work, others have built-in lithium ion or nickel manganese cobalt (NMC) batteries which you charge from a regular power socket.
The advantage of having removable is that it provides the opportunity to extend your range by carrying spare charged batteries or swapping them out with flat ones – this is also useful for commuters who don’t want to leave their e-bike charging at work all day and can be taken out and about with you like a regular bike!
E-bike batteries come in a number of different designs. This depending on voltage, amps and watt hours or kilo watt hours (kWh).
Be warned that some battery manufacturers overstate their specs so you should find out what you’re buying before parting with your hard earned cash!
For example 36V 10Ah might sound like a lot but if the maximum voltage is actually 36.8V (3.8V per cell) then you’re really only getting just over 3Ah of charge not 10!
5 Benefits Of Owning an E-Bike
There are many reasons why someone would want to own an e-bike rather than a regular bicycle. These include:
1) They are easier to ride, more comfortable and will enable you to go further for longer with less effort.
2) They are cost-effective. They can be purchased for less than $1,000 and will last many years with the proper care.
3) They provide a sustainable mode of transport that makes you healthier as well as reducing your carbon footprint.
4) They are more efficient at travelling long distances and will enable you to get around quickly and easily.
5) They are a lot of fun to ride!
How To Choose The Right E-Bike For You
When it comes to e-bikes, there are many options. The first thing you must decide is if you want an electric bike or a moped.
If your answer was anything but “e-bike,” then this article isn’t for you (get the hint).
There are two types of electric bicycles: pedal assist and throttle.
Pedal Assist E-Bikes (PAE)
are exactly what they sound like: bicycles that help you pedal. They’re the most popular choice in the US and Europe because they give riders a bit of assistance but still require some effort on the rider’s part.
by contrast, don’t need any pedaling and simply use a throttle to get where they’re going once the battery is engaged.
Most European countries only allow PAEs. This can be frustrating for would-be customers who want to own a throttle bike, but it makes sense when you remember that these bikes were developed first for commuters.
Since throttle bikes also allow riders to go faster with less effort, there’s an understandable concern among European regulators about safety on the road.
If you’re looking for a bike to help get you from Point A to Point B, a PAE is probably the best option. They’re great for people who want to stay active, but might not be in great shape or have a lot of time to ride every day. PAEs can also help reduce fatigue, as the electric assist takes some of the work off your hands.
If you’re looking for more of a leisurely experience, or if you want to be able to take your bike on trails and paths that are off-limits to cars, a throttle bike might be a better choice. Just keep in mind that they’re not allowed on many European roads, so make sure you check the regulations in your country before you buy.
How To Care For Your E-Bike
Here are a few tips on how to take care of it, and how to keep it in good condition:
Store your e-bike
If you want to store your e-bike in a dry place, away from sunlight, you can use a storage shed or garage. Make sure the area is well-ventilated, and that the bike is not exposed to extreme temperatures, either hot or cold. You may also want to consider using a bike cover to protect it from the elements.
Regularly check the tire pressure
You should check the tire pressure on your e-bike regularly, and keep it at the recommended level. Over time, the tires will lose air, and if they’re not inflated properly, it can affect the performance and lifespan of the bike. You can find the recommended tire pressure for your bike in the owner’s manual, or on the manufacturer’s website.
Clean your bike regularly
It’s important to clean your e-bike regularly, both the frame and the components. This will help to keep it in good condition, and it will also make it look nicer. Use a mild soap and water to clean the frame, and a dry rag to clean the components. Be sure to check for any leaks or damage, and repair them as soon as possible.
Keep the chain clean and lubricated
The chain is one of the most important components on your e-bike, and it’s important to keep it clean and well lubricated. You can use a chain cleaner and lubricant to do this. Be sure to follow the manufacturer’s instructions, and don’t apply too much lubricant, or it will end up getting all over the frame and components.
Regularly check the brakes
It’s important to regularly check the brakes on your e-bike, and make sure they’re working properly. If the brakes are not functioning correctly, it can be a safety hazard. You can test the brakes by applying pressure to the brake levers. If the bike slows or stops abruptly, the brakes are working properly. If not, you may need to adjust the brake pads or take them to a bike mechanic for repair.
Make sure that all electrical connectors are tightly fastened and corrosion-free
The electrical connectors on your e-bike can become corroded over time, which can cause the bike to stop working properly. It’s important to check them regularly and make sure they’re tightly fastened. If you see any signs of corrosion, use a wire brush to clean them off, and then apply some dielectric grease to protect them from further corrosion.
By following these tips, you can help to keep your e-bike in good condition, and ensure that it’s running smoothly and safely!
