Best Electric Hybrid bikes
Electric hybrid bikes are the fastest selling style. Their flat bars, usually wide tyre, and commute friendly fittings - such as mudguard mounts and rack mounts - make them extremely practical machines.
The motor can be housed in the rear hub, or at the cranks, and the torque will vary - low torque models offer a natural pedalling assistance, but high torque versions will move off the lights more quickly.

The Turbo Vado is commute ready thanks to fenders and a rear rack
(Image credit: Future)
A fun ride that’s great in urban environments but also provides a confidence-inspiring ride on rougher terrain is what the Specialized Turbo Vado is all about.
If you're after a bike that is fully integrated with lights, fenders and rack (27kg capacity) as well as security (on the App & removable battery using a key), then this represents a straight forward choice. Only the weight, and to a lesser degree cost, need consideration.
We found the 70Nm/250W custom-tuned motor applies power seamlessly and powerfully as soon as you push down on the pedals. Range is excellent too - 95-130km / 60-80 miles should be easily attainable using the default settings of "Sport' and '50% power'. There is an Eco mode as well as Turbo, so if you're careful you can expect much greater range.
It is a heavy machine at 60lbs/ 27kg, so not easy to lift, so anyone needing to navigate steps in or out of the bike's storage place will need to take this into consideration, but aside from that we found the Specialized Vado Turbo to be a joy to ride.

The Ribble Hybrid AL e is a road-going hybrid bike that’s equally at home on gravel paths and trails, with a comfortable and confidence-inspiring upright riding position, so great for returning or newbie riders.
For us, we think the bike is one of the best looking hybrids we've ever come across, with the design hiding away the motor incredibly well, although we were a little sad that adjusting the seat post left behind scratch marks. The fully loaded package includes fenders (mudguards), lights and a rear rack making it perfect as a daily commuter or for ditching the car when going to the store, although we did find these a little rattily on test.
The Ebikemotion motor delivers its power smoothly and efficiently and offers long-range in between charges, making the Ribble far more than just an A to B bike.
Understandably it doesn't perform in the same way as the Canyon Grail:ON in terms of fast and tight torque, but tap along and it will tick over nicely, taking the top off any strenuous rides.
With all the added extras as standard and classy looks, the Ribble Hybrid AL e is a great electric bike for the money.

Tough to ride without pedal assist

Hill starts are hard before motor kicks in
We absolutely loved zooming around on the speedy Ride1Up Roadster V2 with its five levels of power assist. If you're anything like us and are more used to training and racing on standard road bikes it can easily become your guilty pleasure - it's fantastic fun to ride.
The bike was so quiet, even on level 5, convincing onlookers that our tester had to be some kind of super hero to ride so fast up 15 per cent climbs. The only downside - in common with other e-bikes that only assist when you're pedalling - was where there was a requirement for a hill start, the cranks had to be turned over in order to get the motor to engage, creating a pregnant pause at the lights, before vavavooming off.
The claimed 24mph maximum assisted speed (in the US) needs input from the pedals to reach on the flats, but without a doubt it's noticeable downhill, where other bikes, such as the Wilier Cento1Hy Ultegra Di2 e-bike auto assist would cut out and slow you down.
This extra speed also puts the bike into a class 3 e-bike, meaning that it doesn't meet EAPC rules in the UK, but that's by the by as US brand Ride1Up doesn't currently ship there.
If you are in a country lucky enough to be shipped to: the US, Canada and Mexico, then it's a great option and one that has a very high fun-to-dollar ratio.

The Canyon Precede:ON is an efficient automatic transmission city bike that performs well in multi-terrain settings whether for utility or for leisure purposes thanks to a powerful motor and control panel.
With built-in accessories such as lights, mudguards, rack and kickstand all the trappings are there to make for a comfortable ride with style straight out the box. All these add ons however do make it one of the heaviest e-bikes on the market, even heavier than the Specialized Turbo Vado.
We really loved the Canyon Grail: On and it's great to see the Precede:ON also be kitted with the Bosch Performance Line CX motor, although ideally we would love to see a little more juice in the battery to support the other impressive spec.
With everything you need straight out the box, including navigation system and lights, it's the easiest way to swap driving/ public transport for a bike, but it is at the higher end price tag wise. There are a couple of models to choose from, which also takes the cost down a touch, but with a six year guarantee, it could be a savvy investment.
The only other point to note is that Canyon has a direct sales model, so you'll have to buy directly from the brand here.

Frame not the most comfortable
The Giant Fastroad E+ Pro is another road-going hybrid bike with flat handlebars to promote a comfortable ride position for even the rustiest of riders, in fact we enjoyed riding this great electric hybrid road bike so much we gave it a Cycling Weekly Editor's Choice Award.
The tires provide plenty of squish and the ability to go lightly off-road. However on test we found the aluminium frame and fork quite stiff, which will suit those used to a traditional road bike’s feel and riders looking for a speedy commute, but worth bearing in mind if you’re used to a softer hybrid feel.
We really liked the bike's integration of the battery, which can often be a design factor forgotten about on hybrid bikes. We were also really impressed to see the spec on the FastRoad, with hydraulic disc brakes and quality Shimano shifting, with a compact chainset and wide range cassette at the rear to provide plenty of gears for the hills all making an appearance.
All in all, we think it's a great electric hybrid bike for a fair price that will have a lot of appeal to lots of different riders.

Best Electric Folding Bikes
Folding electric bikes are practical if you have a train journey forming part of your trip or are low on space. Being small, the battery and motor can represent a large percentage of the weight, so the focus is often on reducing this as much as possible.
Mileage on folding bikes is often low, since they're typically used to ride to and from train stations, so battery range isn't always a major consideration.
If you are considering going for a folder, you might find our buying guide page dedicated to helping you find the best folding bikes a useful read.

Not a lightweight carry
The G4i is a solid choice for a commuter, with the option to add many accessories such as mudguards (fenders), a front and rear pannier rack, integrated lights, lock holster and a travel case.
The design folds in half, so that you can push it on its wheels rather than needing to carry it, or you can fully fold it into a compact package. There's built-in rear suspension, concealed cabling and a fully enclosed drivetrain.
It features a discreetly integrated USB port on the handlebar, enabling owners to charge their phone or other small devices from the bike’s battery when not in use - although we found the quality of the integrated phone mount didn't quite match that of the bike itself. The same goes for the LED display, which we found to be rather basic - although the information it provides is useful.
It's also likely to be pretty low-maintenance given that the drivetrain is completely enclosed. This makes sense, given that commuting year round usually means cycling in the wet at some point. The G4i utilizes a Shimano Nexus 3 speed internally geared hub. With 1” of elastomer suspension and 2.35” wide tires, it is one of the more comfortable small wheelers. Single-sided wheel attachment means you don’t even have to remove the wheel, should you puncture one of the 20” wheels.
The 500W (250W in the UK/EU) G4 electric motor and 375Wh Lithium-ion battery is claimed to provide a range of up to 80km (50mi), but the most we managed to get out of it was just 44km (27mi). To be fair, that was in one of the more 'assisted' modes and we always had the daytime running lights on - and the city of Bath is well known for its brutally steep hills.
The bike is available from 17.6kg / 38.8lbs. However, as the weight is centred low on the frame, this at least makes the ride more stable. The folding mechanism has been improved since previous versions and can be quickly collapsed into a small package - Gocycle says this can be done in as little as ten seconds; we found it was closer to 20.

Heavy for a folding bike
Tern has numerous folding bike options, with the electric model options also growing in the fleet. The Tern Vektron S10 features 20-inch wheels and a 400-watt battery that can power you for 40 to 90 miles, depending on how much you use the assist.
We haven't tested this version, but highly rated the non-electric Tern Verge X11 and believe that you won't be disappointed in this electric cargo model.
To help the rider find the perfect fit, the stem and saddle are adjustable, making it a good interchangeable option for the whole family, from 4'10" to 6'5". Coming with an integrated rack, compatibility with child seats is a breeze as no additional adaptors are required.
Its integrated rack will be fantastically useful, but will add to the already quite large folded down package size, so if it's stowaway capabilities you're after, you might be better off with the Brompton Electric Folding bike option.
The bike boasts dynamo powered lights, alongside hydraulic disc brakes and highly regarded Shimano Deore groupset. The high spec does push the price up though, and weighing 22.5kg /48.7Ibs makes it a fairly hefty folder, and a limited one at that.

Hard to get rear wheel out, and back in
Brompton has had the Electric C Line in its range for a while. The Electric P Line takes the same electric drive tech, but packages it in a lighter weight model thanks to the titanium rear triangle in place of steel, dropping the weight to a claimed 34lb.
The removeable battery pack in a backpack makes the bike easier to carry than that headline weight would suggest as well. It's easy to clip it back onto the frame when you're ready to roll but, as with the standard Brompton, the high foldability remains, making the Electric P Line easy to store.
The Electric P Line has Brompton's clever four-speed gearing system. It comes with an ingenious two-piece derailleur which has been designed to fit inside the narrow fold - one part has a spring mechanism with one jockey wheel that is mounted and tucked under the chain stay, and the second part is a fixed chain tensioner that’s mounted below the rear drop out.
We did find however that the rear derailleur was a little fiddly to adjust and we'd have liked a smaller bottom gear, but both are relatively minor issues.
Best Electric Road and Gravel Bikes
The best electric road bikes will favour low weight. The expectation is that at times you might exceed the 25kph legal e-bike limit stipulated by many countries, and at that point, you'll want a lightweight bike. The motor will often be low torque, which makes the assistance feel more natural.
Hub based motors are becoming increasingly common in this category. They keep the weight low, and also allow the chassis to look almost identical to a non-assisted bike.

With geometry matching that of the Ribble Endurance SL Disc, the Ribble Endurance SL e gains a motor and battery, making it a great option for riders looking for subtle performance enhancement.
As with its non-electric equivalent, the Ribble Endurance SL e was also awarded a Cycling Weekly Editor's Choice award, mostly due to its low overall weight, spec and incredibly subtle integration of the motor and battery.
On hills the bike was fantastic at giving us a much needed boost in a natural and smooth linear delivery, but on the flat the legal e-bike speed limit of 15mph for the UK (where the bike was tested) did hold this otherwise great electronic bike back.
We felt that the location of the charge point on top of the bottom bracket was a little vulnerable, so it's important to double check it's covered up, particularly in wet conditions
The other slight gripe was the position of the power on button on the top tube. Once it's on it's on, but trying to locate it does mean taking your eyes off the road for a couple of seconds, which isn't ideal.
With a similar profile to the Wilier Cento1HY Ultegra Di2 e-bike, but kitted out with the lower price point, yet highly respected, Shimano 105 groupset, the Ribble Endurance SL e could save you half the money.

‘Turbo Connect Unit’ position makes it awkward to use
The Specialized S-works Turbo Creo is the brand's first venture into the world of road e-bikes and it is not a disappointing one. If you're able to look past the eye-watering price tag, you will be getting all the pros of a road bike but with a bit of, as Specialized puts it, 'oomph'.
This beautiful bike gets the same FACT 11r frame as the S-Works Roubaix, which means it already has a naturally racy feel, and thanks to its super lightweight construction, means that it's happy to be ridden without any assistance at all.
When taking advantage of the power, Specialized's own SL1.1 motor delivers smooth assistance to your ride and doesn't have the surges of acceleration you may find in some other e-bikes. That and its impressive battery life, which we found to be one of the longest on test, means that you do get a truly excellent e-bike.
It's a bit like the F1 of e-bikes as it comes with a lot of technical integration, such as the ability to connect to its own app and dial in the motor for your style of riding. This is really helpful when using the bike to help with training and ensuring that the motor only kicked in once the tester was at a certain speed/ wattage.
The good news is that there is a spectrum of the Specialized Turbo Creo with the SL Comp E5 available for nearly a third of the price. You do lose some of the spec of course, but both are still great options.

Looks won't be to everyone's taste
The Cannondale Topstone Neo Lefty 3 is an electric gravel bike - that means it blends drop handlebars with burly tires and suspension, so it's designed for on and off-road riding.
Running on 650b wheels keeps the rear end tight and nimble for almost any terrain, although this is an area where you might consider a future upgrade as the WTB ST i23 rims don't quite match the capability of the rest of the bike. It'll still shock you with its power delivery (hold on to your hats), but the looks are best described as an acquired taste.
It'll leave you in a similar giggly mess as the Canyon Grail:On CF 8 eTap does, just pure grin inducing fun on any ride. In fact, on test it proved to be a bit of a handful, and possibly provides too wild a ride for a lot of riders. If you can learn to love the looks, and tame the beast of the torque you honestly will struggle for more fun on two wheels.
This bike is unrivalled in its class in terms of motor performance while the suspension adds another layer of capability to the package and blurs the gravel/MTB divide even further.

Auto-assist not to everyone’s liking
Gaining a much-deserved Editor's Choice award, the Wilier Cento1 Hybrid is the e-bike for the road riders who still want the feel of a race bike. The Cento1 Hybrid is a good looking lightweight machine, which will assist you up those tough climbs, with plenty of power on tap.
On test, we found the supporting ebikemotion system, which is smartphone and PC app friendly, a doddle to use, with automatic syncing to Strava.
Some riders will love the automatic assistance, as it will immediately kick in when the going gets tough. However, this can be a pro or a con, depending on your ride assistance preference. If you would rather be the master of your own electrical deployment, then you might find the auto-assist a tad frustrating and just a little over torqued.
It's not the cheapest of bikes by any stretch, and the Ribble SL e could almost go toe to toe, but the Wilier is the no compromise option, which is reflected in the price tag.

Electric bike buying advice
There are a whole host of reasons why you might want to invest in one of the best electric bikes.
Perhaps you have to travel with lots of cargo, and the added power can mean the difference between using a car or still spinning your two legs.
Or maybe you want to start commuting to work, and an electric hybrid could be a great option for helping you cover the miles, without turning up at work in a sweaty mess and in need of a shower.
The benefit is obvious: less effort = less sweat. Hauling heavy luggage is an option, and you can often even keep pace and feel more comfortable in traffic. A hybrid e-bike with a rack and fenders and you've got a seriously practical bike that can replace many a car trip or having to use public transport.
You might be recovering from injury or illness and the added boost of a motor might help you get back out there again. Or it might simply be the case that you're not as young as you once were.
It is absolute hearsay that electric bikes don't provide an exercise benefit, you do still get a workout when riding an electric bike.
Scott's Hybrid uses a mid-drive motor
The biggest difference between an electric bike and a motorbike is that the e-bike can only assist its rider, its motor cannot be the sole source of power for the bike. To clarify, in order for an electric bike to be legal, in many countries it can only assist a rider up to 25km/h (that's roughly 15.5mph). This applies to most of Europe and Australia — if you live in the US, keep reading.
Outside the US the motor inside the bike can only be a maximum of 250w and cannot be operated by a throttle like you'd find on a motorbike. Which does mean you'll have to use your legs!
The rules in the US are a bit more difficult to follow as the laws can vary state to state, and federal law surrounding e-bikes may say something different again.
The Bicycle Product Suppliers Association has sought to clear up some of the confusion, slotting e-bikes into a three-class system, all of which are limited to 750-watt motors.
The laws surrounding where and who can ride which class of e-bikes also varies state to state, but the TL:DR version is class 1 and 2 are permitted anywhere bikes are allowed, and class 3 are okay on roads and in bike lanes, but not multi-use paths, and have rules surrounding helmet use and minimum rider age. Thankfully the lovely folks over at People for Bikes have a handy guide that breaks the rules up by state.
Most e-bikes come in the form of a Pedelec or pedal-assist, which monitors the input of a rider and assists as much as possible up to the region-specific top speed.
Less common are Twist-n-Go models, which allow riders to operate the input of the motor from a switch (or even a throttle). Most places classify these as a moped and you may need a licence, insurance, and a full helmet to ride them.
A hub mounted motor
The peak output of an electric bike is normally expressed in two measures.
The power output of the motor is measured in watts. Most electric bikes have a maximum continuously rated output of 250 watts, as that's the power that regulations allow in many countries. Their peak power may be higher than this - think power required to get you started from a standing start.
Torque is the turning effort that the motor can add to your own pedalling. It's measured in Newton-metres (Nm).
Torque output varies considerably between motors. Lower priced electric hybrid bikes and many folders may have a torque output of around 40Nm. That's also the power output of the motors on some electric road bikes, where the motor is designed to add extra power to assist a fitter rider rather than o pull you up a hill.
Mid-range motors, such as are found on many electric city hybrids, and some electric road bikes typically have outputs of 50Nm to 65Nm. Electric mountain bikes and some electric gravel bikes may have torque outputs of 90Nm or more to give plenty of grunt when climbing steep off-road inclines.
There are really only three options for e-bike motor placement: either on the front wheel, the back wheel or the cranks.
Placing the motor at the cranks offers much better weight distribution, which makes the bike more stable — a key consideration for both road and mountain bikes.
Hub based motors, found in the rear wheel, are usually lighter, so you're more likely to find them on electric road bikes. Motors in the front wheel are a lot less common, but you may find them on some hybrid e-bikes and folders.
Most motors are now placed around the bottom bracket for a better distribution of weight
Another consideration worth thinking about is electric bike batteries.
Generally speaking, like motors, you get what you pay for. No battery will have infinite power, or be totally invisible, even on the best electric bike - but the more you spend the longer the range/ the more subtle its placement.
Battery capacity is measured in both watts (watt-hours, Wh) or amps (amp-hours, Ah). In most cases, an e-bike's battery capacity lies between 250Wh-600Wh or 7-10Ah.
Typically, you should get around 800 charge cycles from the best electric bike lithium-ion battery before you'll need to replace it.
How far you can go on a single charge depends on range of factors, including the terrain, but a rule of thumb you can expect a riding range of anywhere between 25 and 75 miles of run time on a full charge. Although be warned, the more assistance the bike gives, the more power it will draw from the battery.
Here, a 9ah battery is hidden in the seat

E-bikes do have slightly different components to standard bikes, the obvious ones are the battery and motor.
In terms of motors, the big names are Bosch and Shimano. Shimano Steps was the first e-bike specific groupset from the Japanese giant and it features a mid-drive electric motor, as well as integrated electric shifters and a torque sensor to smooth out the ride a little.
Bosch is becoming a big name in the e-bike world
Bosch has really embraced the electric bike market and its range of eleven different motors offers a variety of power assistance depending on how much you're willing to spend and the type of riding you're doing. Its models have motors geared to more leisurely riding, more performance-oriented cycling or cargo moving applications.
Other brands such as Fazua, TQ and Mahle ebikemotion are common on lightweight e-road bikes, and these systems have done well when reviewed, so come recommended. Budget electric bikes often use Bafang motors.
Most electric road bikes will come with a normal groupset
(Image credit: Shimano)
The best electric bikes are likely to come specced with some form of hydraulic disc brakes. The added speed and weight of an e-bike will definitely warrant the extra stopping power.
Other areas that can differ are tires, which tend to be fatter, even on the road bike options, anywhere between 32mm and 40mm of rubber is most common on the hybrid options. The extra wide tires will help absorb the impacts of the heavier frame as well as providing more grip and stopping power to balance the extra weight and speed.
The more expensive, lightweight carbon road electric bikes do now come with leaner 28m tires, perfect for keeping up on the club run.

Paul started writing for Cycling Weekly in 2015 and since then he’s reviewed hundreds of bikes and thousands of other pieces of cycling equipment. He’s been cycling for a lot longer than that though and his travels by bike have taken him all around Europe and to California. He’s been riding gravel since before gravel bikes existed too, riding a cyclocross bike through the Chilterns and along the South Downs.
Paul Grele
Paul reviews both bikes and equipment for Cycling Weekly and has 40 years of riding under his belt across a variety of disciplines including road riding, commuting, a self-supported Land's End to John o' Groats trip, XC mountain biking and several Polaris Challenge two-day events. Naturally for a reviewer he loves bike and kit design and has even fillet brazed a couple of framesets himself.
Where we've been able to link to a review, it means that we've put the bike through its paces. This means that we've ridden it over varying terrain and distances to assess it's performance across a range of factors. For e-bikes this typically means that we'll have considered the quality of the motor and battery, from ease of use to charging time and range, while with regards to folding e-bikes we'll have also tested the folding mechanism for ease of use as well as the general suitability of the bike for commuting purposes.
Like regular bikes, we'll also consider the ride quality and the choice of components and how they impact key areas such as comfort, gear range and braking.
Where we haven't yet had the chance to review an item, we're still confident in recommending it as one of the best, because we either know the brand really well, and have probably tested another product or the previous version and can still happily recommend it as one of the best.
Brompton's P Line features a titanium rear triangle, and is offered as a lighter sub-10kg option to the original all steel Brompton, now called the C line, which will weigh in between 24.7 and 26.6lbs /11.2 and 12.1kg. During our testing we really noticed the difference, and while 22lbs / 10kg is still a fair amount to carry around for longer periods, the reduction in weight did make the P Line altogether easier to pick up and take with us.
Like all Bromptons it's nicely put together with umpteen clever little design hacks. We really liked the saddle up, roll-ability, not offered on previous P Lines, that allowed us to easily wheel it around a station concourse via the saddle and maneuver it around commuters during the rush to the train.
The four-speed gearing system is just as clever. It comes with an ingenious own brand two-piece derailleur which has been designed to fit inside the narrow fold - one part has a spring mechanism with one jockey wheel that is mounted and tucked under the chain stay, and the second part is a fixed chain tensioner that’s mounted below the rear drop out. We did find however that the rear derailleur was a little fiddly to adjust and we'd have liked a smaller bottom gear, but both are relatively minor issues.
All told, we found the new P Line to be more practical, more 'pickupable', more maneuverable than before, which truly makes it one of the best folding bikes out there.
