EcoRide Ambassador 28" 8-speedPowerful electric bike in comfortable version with lots of functions.
+ Stable construction, well balanced, powerful motor, plenty of accessories included, easy to adjust
– Slightly lagging pedal-assist, very heavy without electrical assistance, long charging time, caliper brake
The Crescent Elda is a comfortable and robust hybrid model with high quality levels throughout and a good range. The central motor gives the bike a low centre of gravity and good stability, but also a high torque. The torque sensor detects how hard you're pedalling and adjusts the motor power to provide a natural feeling as you pedal. Central motors are more powerful than front and back wheel motors and deliver a high torque. Even without electric assist, the bike is easy to cycle with low rolling resistance and a relatively low weight. The sitting position is slightly forward leaning, just like in all hybrid bikes, so perhaps it isn't suitable for everyone, but if you're used to cycling often this position will feel comfortable. The front forks, with shock absorbers, provide good levels of comfort even on a poor surface. The control unit and display are relatively simple to use and understand, but it's a shame that the display doesn't show the current time and how far you've cycled.
The Elda is equipped with Shimano hydraulic disk brakes. They need very little maintenance and are a guarantee of secure braking power even when the bike has been loaded with bags or is towing a trailer. The externally mounted rear gear is also one of the better Shimano models. This is positive, but it's important to be aware that externally mounted gears require more maintenance and lead to increased wear on the driveline, above all in combination with the powerful central motor. This means that the chain becomes skewed and must be changed more often. However, the advantage is that you get a lower weight bike with quick acceleration. But despite the fact that it falls in the medium price class, the Elda isn't very well equipped in terms of accessories. So you need to be prepared to spend extra on things like lights, a luggage carrier and a basket. In addition, although of good quality the saddle is quite hard. If you want to upgrade your comfort levels, we recommend a softer saddle, or perhaps even better either a saddle post with shock absorbers or a gel cover for the saddle. In general, though, you quite a lot of high quality bike for your money. The Elda's stable frame design and the choice of high quality components make it an excellent choice for anyone who cycles every day, such as the cycling commuter.
+ Powerful central motor, high quality components, natural bike feel, very good braking effect, stable frame design
– Few accessories, slightly hard saddle, quite a bit of maintenance
Specialized's Vado 4.0 NB is a monster of an electric bike in terms of its careful design and build quality. It uses exclusively high-quality brand components which are attractively integrated into the bike design and perform faultlessly. For example, the motor and battery are fully integrated into the frame, which gives the bike a stylish and harmonious appearance. The motor is powerful, silent and responsive, largely thanks to the internal belt drive. The gear system has 11 speeds, which are fully sufficient for helping you to adapt rapidly to the challenges of an urban environment. The charging time is short, so if you stay in the town where you can easily find charging points between bike journeys, you won't have any problems. The centre motor and the battery integration into the lower frame tube give the bike a low centre of gravity, making it stable. This type of motor is more powerful than front and back wheel motors and delivers a high torque. A torque sensor detects how hard you're pedalling and adjusts the motor power accordingly, giving a natural feeling as you pedal.
The Vado 4.0 NB has a user-friendly display with all the functions you need. For example, you can use it to control the bike lights. The externally mounted rear gear is one of the better Shimano models. However, you should be aware that the combination of a powerful motor and externally mounted gears lead to increased wear on the driveline. Externally mounted gears also require a little more maintenance than other gear constructions. But among the advantages are fast acceleration and low weight. The Vado 4.0 NB has substantial hydraulic disk brakes, which give plenty of braking power and very little maintenance work regardless of weather conditions or load. The saddle is also good, but rather hard if you're going to be cycling far. The sitting position is slightly forward leaning, as is normal on hybrid bikes. The front forks, with shock absorbers, are very stable - as is the bike as a whole - and provide high comfort even on bumpy surfaces. Without electrical assistance, the bike feels tough to pedal at low speeds. This may be because the wide tyres are providing more resistance. In any case, if you cycle fast under your own power, it doesn't feel sluggish. Specialized's Vado 4.0 NB has very few shortcomings, but the price tag reflects this. This makes it most suitable for cyclists who don't want to compromise on quality, comfort or aesthetics and who are prepared to pay to get what they want. If you're looking for a powerful premium class hybrid for everyday commuting that works equally well on all types of surface, this is an electric bike that you'll have fun with for many years.
The EcoRide Ambassador 28" 8-speed is an easy-to-ride standard model with a stable frame that can cope with extra loads. For example, you can load it up with shopping and your child without it feeling unstable, despite the step-through frame. The front wheel motor is powerful and gives rapid acceleration. The only negative point is the delay of about a second before the pedal-assist kicks in or stops, which can feel a bit unnatural. The pedal-assist is the type that gives constant electric assistance on the basis of four fixed positions. So you can pedal without much force but still get a lot of electric assistance from the powerful motor. Overall, this means that the Ambassador 28 8-speed is very easy to ride as long as you're cycling with the electric assistance on. However, if you turn it off and instead ride it as a classic bike, it's heavy and hard to cycle. In other words, you should always make sure you have enough range left in the battery to get you from A to B. We'd also have liked a slightly quicker charging time. The battery is a powerful variant with high-quality cells that should be able to cope with 1000 charges. In practice, this means twice around the Earth, so it should take a while before you have to replace it.
Both the saddle and upright sitting position are comfortable. At the same time, the adjustable handlebars mean that you can adapt the sitting position to your height. Another advantage of this electric bike is the control unit. The display shows pretty much all the basic functions you could want while at the same time being easy to understand. The only information we'd have liked is a clock. The Shimano gears work well and require minimal maintenance, which is a plus point. During the test period, the caliper brake delivered good braking power, but we know from experience that the power in this type of caliper brake is negatively affected by moisture and dirt. So you should keep the caliper brake clean, test it regularly and remember that the bike also has a foot brake. Given the price, we think that it really ought to have disk brakes. However, the comfort, stability and upright sitting position of the Ambassador 28" 8-speed make it suitable for commuters. The fact that you can also carry children and shopping make it a good complement to a car.
+ Stable construction, well balanced, powerful motor, plenty of accessories included, easy to adjust
– Slightly lagging pedal-assist, very heavy without electrical assistance, long charging time, caliper brake
The Biltema Low Step 28" 7 speed is a classic standard model bike with quality gears and plenty of included accessories. You get everything you're likely to need to get started, such as a lock, lights, bicycle basket and bell. This electric bike is also delivered with a luggage carrier, but it isn't suitable for installing a child seat on. We find the aluminium frame to be rather wobbly. So it's perfectly understandable that you aren't recommended to load it still further with a child over the back wheel. Nor should you carry any other heavy loads, whether at the front or back. Otherwise, it's easy to ride. The pedal-assist has a movement sensor so the motor gives a specific power regardless of how hard you're pedalling. In other words, you can pedal very little but still cycle at a good speed, assisted by the electric motor. Unfortunately it takes almost two seconds before this starts to deliver power and the same before the motor stops when you've stopped pedalling. This often feels rather unnatural, and a bit discomfiting. The front wheel motor is also quite weak and accelerates slowly. But it still gives reasonable assistance up hills and the low acceleration could mean less wear on the motor components.
It's easy to get used to the Low Step 28", even for beginners. The electric bike has a user-friendly but rather minimal display. We would have liked to see a distance meter, speedometer and clock, but at least you can see the power and battery status. The bike delivers good power to the brakes. But remember that caliper brakes can be negatively affected by dirt and moisture. It's important to keep brakes clean and to test them at the start of every bike journey. As well as the caliper brake, the bike also has a foot brake. The combination is a slightly unsatisfactory solution compared to disk brakes, but on the other hand the bike is a budget model. Other than the hard and rather lumpy saddle, the sitting position is quite comfortable. The adjustable handlebars make it possible to adjust the sitting position to the rider's preference. One slight negative is that the gear shifter is rather reluctant to rotate when you change up to a higher gear. However, the gear system is generally of good quality. The one-year guarantee is very short, and given the price class you have to assume that components such as the battery and motor will have to be replaced within a two-year period. This might turn out to be expensive. A universal kit costs upwards of £500. In other words, there are a number of negative aspects to take into account here. But if you want a relatively cheap, comfortable electric bike for shorter journeys with light loads and don't want to have to pedal too much yourself, it's a relatively good buy.
+ Plenty of accessories, quality gears, adjustable handlebars
– Delay when starting/stopping, short guarantee, slow acceleration, wobbly frame, only small loads, low braking safety
We list below all of the properties and factors that affect how an electric bike performs on the roads, in terms of performance, ergonomics and function. When buying an electric bike, regardless of whether you buy it via a reseller on the internet or via a physical bicycle shop, it's useful if you're clear about what type of requirements you have. Start with how often and how long you'll be using it for, and the type of terrain. Our guide below will then help you choose which type of electric bike will best suit you.
The control unit constitutes the electric bike's computer – its brain – and is the device that keeps track of everything. This includes speed, battery status, output and other important values. The cycle computer is often equipped with a screen so that you can see these values yourself, for example in the form of how far you've cycled and how much longer you can use electric power before you need to recharge the battery. You can also change settings, such as how much help you want from the motor when you're cycling.
Naturally, the motor is an essential part of the electric bike. According to an EU directive, the maximum output that this can have if the bicycle is to be classified as an electric bike is 250 watts. If the electric bike has a higher watt figure than this, it can still be classified as an electric bike, but then it will fall under the EU rules for mopeds. This means that other laws apply, together with requirements you must comply with if the bicycle will be used in traffic.
There are a number of different types of motor system, and some of the main manufacturers are Shimano, Bosch and Bafang. They are good at different things, and cycle manufacturers normally choose the type of motor that best suits the electric bike's target group. For example, Bosch make centrally positioned motors which are powerful and suitable for tough terrain, while E-motion make front-wheel positioned motors which are better suited for an urban environment.
The positioning of the motor on an electric bike is important in terms of how you intend to use it. Front-wheel drive electric bikes are better for simple terrain such as an urban environment. The advantages is that this position works with all gear types, you can have coaster brakes, and that the system is relatively cheap and simple. The disadvantage is that it requires more powerful brakes because you get up more kinetic energy in the wheels, that the cables have to be undone if you need to repair a puncture and that you have worse grip on the road.
If you're going to be cycling up and down hills a lot and you want more power, a rear or mid mounted motor is better. The mid mounted type has the advantage that you get good weight distribution, a good grip on both front and back wheels and that you avoid the extra kinetic energy in the wheels. Nor do you need to undo any cables if you need to change the tyres. The disadvantages are that the bicycle needs a special frame and that you can't have coaster brakes with some gear systems.
Finally, we have the rear mounted motor, which is also good for hills and more difficult terrain. The advantages here are that you get a good grip on the road, that it's a cheaper solution because it's a simple system and that it's easy to mount on an existing bike. The disadvantages are that you need more powerful brakes as you get extra kinetic energy in the wheels and that it's not possible to combine this solution with coaster brakes. Another disadvantage is that if the electric bike simultaneously has a battery packet installed on the luggage rack, the electric bike becomes slightly unbalanced as all of the weight is at the back.
The first thing you need to consider when it comes to batteries is whether the battery is even included in the electric bike you're looking at. Because sometimes very exclusive batteries are sold separately. To make a fair price comparison between different models, you should make sure that the price also includes a battery.
The batteries are normally lithium-ion type. This is the type used in the majority of machines and tools today, and the advantage of these is that they keep their charge well between charges. They're also easy to use and charge. However, you should remember that this type of battery should never be allowed to go completely flat, because this can mean it stops working. They also don't tolerate cold very well, and this will impair performance. You should therefore keep them indoors when it's below freezing outside.
When you buy an electric bike, it's important to choose one with sufficient battery capacity. Batteries have different capacities. However, the capacity isn't easy to compare because it is sometimes stated in Ah, sometimes in Wh and sometimes in range. Ah stands for ampere hours and states the battery capacity to deliver current over time. Wh stands for watt hours and states the capacity to store energy. The range is simply how far you can cycle with the electric bike before you will need to recharge it. Normally most bikes state the range, for example 120 kilometres. But sometimes it only shows ampere hours, and you'll have to ask what the range is for such electric bikes.
In addition to to battery capacity, the position is also important, and is above all linked to the motor position. If the motor is at the front and the battery is on the luggage rack, you often have good balance in the electric bike. The disadvantage with a battery on the luggage rack is that it's hard to find room for a child seat. Some electric bikes have the battery on the frame to create a lower centre of gravity, and this can also have its advantages depending on the rest of the design.
The charging time is important because you generally want the battery to recharge again as quickly as possible so that you don't have to wait for it. Many manufacturers today have systems where you can quickly charge up to a certain point – for example up to 80% capacity – and then the last few per cent are slower. This means that you can do a quick charge to get yourself home.
Many electric bikes are equipped with rotation sensors. This means that the additional power provided by the electric bike is determined by the speed at which you pedal. In other words, the rotation sensor makes sure that you get a boost from the motor. It is activated when you start pedalling, and then gives a uniform speed for as long as you continue.
However, it can't tell how much effort you're making. In other words, it doesn't give you more power if you're pedalling harder up a hill. Instead you have to change down a gear so that the electric bike doesn't overpower the assistance. If you don't want to have to do this, you need an electric bike equipped with a power sensor. If you have to expend more effort while pedalling, this will activate more assistance. If you live in a hilly area, it may be sensible to think about whether this is something you need from your electric bike. The disadvantage is that this function can negatively affect the range.
Just like on a normal bicycle, the number of gears is an important factor if you're going to be able to ride through a range of environments, from winding forest paths to tough hills. Even if you get a power boost from the motor, it's nice to be able to change down a gear to go uphill, and change up when you want to cycle fast on a long, flat straight. If you're going to cycle every day, we recommend at least 7 gears. A good rule of thumb is to stick to the number that you're used to. If you have 10 gears on your ordinary bicycle today and you're happy with this, you should try to get an electric bike that has the same number.
The gear system can either be external or internal. The former is most common on sports bikes as this provides lower rolling resistance and smaller jumps between the gears. This makes it good for cycling in rougher terrain. The latter system is more common among urban cycles as it's largely maintenance free and you don't have to put up with a clattering chain. However, there are bigger jumps between the gears, a higher rolling resistance and higher weight. Of course there are also disadvantages with the external system, primarily that it requires more maintenance and must be regularly adjusted, but also that you can only change gear while you're moving.
There are a number of different types of brake system on electric bikes. These are usually separated into foot (coaster) and hand brakes. Far from all electric bikes are equipped with coaster brakes as this depends on the overall design. Coaster brakes only work as hub brakes. The advantage of having coaster brakes is that they have very low service requirements. The disadvantage compared to hand brakes is that there are some pedal positions where it's more difficult to brake, and the coaster brake mechanism also weighs more. It's usually the case that if an electric bike has coaster brakes it will also have a hand brake. However, just because it has a hand brake it doesn’t necessarily have coaster brakes too.
Hand brakes are available in a number of different variants. V brakes are the most common. In practice, these consist of two brake pads pressed against the rim to brake the wheel. The system requires a certain amount of maintenance and adjustment, but it's also cheap, lightweight and easy to adjust. However, braking performance can be affected if it's wet out. Another type of hand brake is the hydraulic disc brake. This gives extremely effective braking that doesn't wear the rims and is not affected by weather conditions. However, the system is more expensive than others and also requires bleeding a couple of times a year. The hydraulic systems also include hydraulic caliper brakes which are more like V brakes than disc brakes. The advantage of these over V brakes is that they're more effective as a result of the hydraulic fluid, but at the same time they still have the same problem with impaired braking effect when the weather is wet. They're also more expensive than V brakes. Finally, there are drum brakes, which is a system where the brake pad is pressed against the inside of the wheel hub. This provides advantages in the form of low maintenance costs and not being affected by poor weather. The disadvantages are primarily the lower braking performance. They aren't very good if you're going to be cycling down very steep hills.
Appearance and comfort
There are a couple of things you need to include on your check list when you're considering comfort and electric bikes.
● Size – the electric bike should be right for your height.
● You need to be comfortable on the bike for long periods. Is the saddle padded?
● What's the balance like when you're cycling? One factor that affects this is the positioning of the motor and battery. If they're at the same end of the cycle, it can easily be unbalanced. You can normally check this at the resellers, but you can also read tests of electric bikes where the balance will be mentioned.
● How much does the electric bike weigh? If you sometimes have to carry the bike, this is particularly important.
● Do you have restricted storage space and need to be able to fold the bicycle? Folding electric bikes are available from a number of manufacturers.
Electric bikes have two primary certifications. These are European standard EN 15194:2011 and BATSO 01. If the electric bike is marked with these, it means that it is considered to maintain the correct speed and to fulfil the current safety provisions, including regarding fire and explosion risk from the battery.
Insurance and guarantees
Electric bikes are targets for thieves as a result of their value, and should therefore be protected as well as you can. If you buy an expensive electric bike it can be a good idea to insure it. You can do this through your normal home insurance, as this will include bicycle insurance. You should also make sure that you get a good guarantee when you buy.
Some examples of accessories that can be useful when you buy an electric bike are an approved helmet, a decent lock (you should ideally avoid thin wire locks) and a bicycle pump.
Other examples are: a bicycle bag, bell, child seat, basket, lights and a spare inner tube or repair kit.
