You will typically see that battery terminology is often referred to as 'Ah' and/or 'V'.
'Ah' stands for Amp Hours and the LG batteries in EcoBikes are anywhere from 10.4Ah to 16Ah. That translates into how many fixed number of Amps a battery can sustain for 1 hour. So in essence, Ah is equivalent to your fuel.
'V' stands for voltage and in simple terms, the higher the voltage, the greater the power. Most of the batteries you will find in the bikes we stock are 36v and 48v (the higher voltage being on the high end electric bikes).
When you have both Ah and V, you can work out roughly the run time of each battery.
For example, 36v x 10ah = 360wh (Watt Hours). This gives you a run time for a 250W motor of 1.44 Hours (360wh / 250 = 1.44).
Run time all depends on how much you tap into the battery during your ride. The more assistance you get, the quicker the battery will go down. There's a lot of other factors that also need to be taken into account, weight, gradients, free wheeling, condition of bike, tyres, the type of terrain, etc, etc.
Electric Bike Batteries supplied with the E-Bikes that we stock, currently EcoBike, are Lithium ion batteries.
Most of the batteries in these bikes are from LG, a fairly well known South Korean technology company. Other batteries found in EcoBike is Greenway, a Chinese battery company.
As mentioned in the Volts and Amps FAQ, range is dependant on many factors and claims made by the bike manufacturer have to be taken in the same way as car manufacturers claims regarding diesel efficiency, I'm looking at you VW! While a range might be stated as 40 to 70 miles, that is typically in optimal conditions, i.e. no wind resistence, etc, as well as rider, i.e. weight/height. It's also dependant on the level of assistance you use during your ride.
Motors are mounted in 3 possible locations on an electric bike.
These motors are located in the rear wheel and are typically self contained, meaning there is little to no maintenance required which can also translate into less failures. Having the motor located in the rear wheel can increase the overall weight at the back of the bike, especially if the battery pack is also located over there too, depending on what the bike is being used for, that could reduce handling.
The motor is independent of the chain, gears and pedal system of the bike, meaning that theoretically, you could loose your chain and still drive the back wheel using only the motor.
Mid-Mounted (Central Hub)
Motors located centrally tend to offer better options to allow for pedal assisted technology. They're also part of the pedals, gear and chain system which gives better options for hill climbing and rough terrain, basically more power and torque! They tend to be more expensive, but give a more natural feeling to that of a normal bike, than a wheel hub motor. The major downside is the strain all of this (your pedalling + motor assistance) puts on the chain and gear components. If you're unfortunate to break a chain whilst out, there is no other way except to push it home.
Mounted in the front wheel hub, these motors give a bike a more even weight distribution, but they can make the front wheel spin on the spot due to no real weight sitting over the front wheel. This won't normally be a problem except if you're out riding in the wet. They also offer low maintenance and unlikely to fail frequently due to the unit being self contained. The feeling of the ride will be a pulling rather than pushing experience. Having the motor in the front does allow you to take advantage of other technologies, such as the Nexus 3 derailleur, where the rear gears can be changed at standstill.
At Ride Green we currently only stock EcoBikes. The motors they use only come in three variants:
If you've heard of electric bikes, then you will of heard of Bafang. Located in Suzhou China, they produce the highest quantity of motors, in the world. Because of this Bafang motors offer very competitive prices at good quality.
Majority of the EcoBikes we stock are supplied with a Bafang Motor with a nominal power of 250W (the amount of power that the motor can supply continiously)
Very similar products and one of Bafangs main competitors, they're even located in the same part of China, Suzhou. Like Bafang, they produce large quantities of electric motors with comparable quality to Bafang. They're company slogan is 'Green Technology, Green Life'.
This company is a Japanese motor company with a factory in Shanghai, China. DAPU motors are renowned for there engine performance and driving comfort. They are one of the leading suppliers of motors in Europe and America. You'll find them fitted to the higher end EcoBike E-Bikes.
A hybrid is typically a combination of the following bikes, City, Road and Mountain. Sometimes referred to as a Trekking ebike, it's a good all-rounder. A jack of all trades, master of none. Excellent for commuting and on-road use, but can go off-road, to a point. It has the sort of features you'd expect on a City or road bike, mudguards, lights and pannier, but the frame is more rugged and resembles a mountain bike in places. If you're likely to do a mixture of riding then I would recommend this style.
The traditional Dutch style bike of sitting upright with a step through frame is typical now amongst many other European Cities, with the UK being no exception. Electric City bikes are based on the same design. Comfortable through the city streets and enjoyable when commuting for work around town.
It kind of goes without saying where these bikes belong. If you can't see any tarmac, then you're in the right place. Wider tyres with deep treads and rugged frames, typically uprated suspension, gears and motors. MTB's are great for off-road and most at home going through dirt, climbing hills or bumping over obstacles. You can still ride them on the road, but they lack features such as mudguards, lights and panniers/baskets, you’ll also get overtaken a lot!
Electric bikes that fold are great if you work across cities or need to commute frequently and can't take a normal bike with you. They do the job of getting you from A to B in comfort and then stow away when you jump on a train to get to your next destination. Versatile and practical they often feature with mudguards, lights and pannier.
On our web shop you’ll find two fairly distinct styles, at least on the EcoBike brand anyway.
Cross member frame design is typical of a traditional Men’s bike and offers additional rigidity over step through design. You’ll also find that it is the design used for Mountain and Road bikes. It is more difficult to get on and off and you’ll need to make sure the bar doesn’t impact you when dismounting from the saddle, like stopping at junctions. It also reduces the size of the bikes that you might be able to ride.
Step through design is typical of a traditional ladies bike. However, this is now becoming classed as a unisex bike in the electric bike world. Step through electric bikes tend to be more rugged than there pedal powered counter parts, but still aren’t as tough as a cross member bike. What they lack in this area is made up by the ease at which getting on and off the bike is achieved. Because of this style it can appeal to a wider range of different riders, for example, the older generation, pensioners, people with disabilities or injuries and less able riders.
