We will be the first to admit, when electric mountain bikes hit the scene, some of the BikePerfect team were sceptical, but that apprehension melted away about three-seconds and two pedal strokes after we first threw our legs over an e-MTB. 

Riding an e-MTB is anything but cheating, and you can still finish a ride on an electric mountain bike just as gassed, if not more so, than on a standard mountain bike. They are an absolute hoot to ride and allow people of all types to ride faster and farther. 

I thought this was Bike Perfect, not Motorbike Perfect

The common refrain surrounding e-MTB's are 'it's cheating', or 'that's a motorcycle, not a mountain bike.' Neither of these are true. Once you take Strava segments out of the equation, forget the notion that everything must be a competition, and remember that experiencing the journey itself is why we ride, you can begin to appreciate how any e-bike fits into its intended market, especially e-MTBs. 

First and foremost, all of the electric mountain bikes featured here are pedal-assist, meaning to get any help from the motor you still have to pedal. There is no throttle, but there are different levels of assistance, allowing the rider to determine the intensity. 

 Regional restrictions

Most e-bikes will either use a drive system from Bosch, Shimano or Yamaha, however, depending on where you live, the wattage output and maximum speed will vary.

UK

The UK adopted a lot of the EU's regulations regarding e-bikes, but with Brexit still up in the air, it's hard to say if these restrictions will change as things move along.

The 'Electrically Assisted Pedal Cycle (EPAC) Amendment Regulations' mandates; electric assistance can only provide 250-watts of aid and must cut out at 25kph. It also stipulates the rider must be at least 14-years old and the bike must be in motion before the motor kicks in.

Electric bikes (and riders) that meet these standards have the same legal standing as regular bicycles and are allowed on roads, bike paths and singletrack.

US

In the US, rules for e-bikes vary from state to state; with 30 states classifying e-bikes as ordinary bicycles, while the remaining 20 label e-bikes as mopeds, scooters or something else altogether. 

Federal law defines an electric bicycle as a "two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts, whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20mph." 

It's worth noting this statute defines the maximum assisted speed of the bike propelled solely by the motor, not when it's being pedalled. To make things more confusing, state regulations can supersede the federal statute. 

The Bicycle Product Suppliers Association has proposed a three-class system which divides electric bikes up based on their maximum assisted speed:

For all three classes, the motor can only put out a max of 750 watts, and the class needs to be clearly labelled.

Even still, the Forest Service, Bureau of Land Management and the National Parks Service categorise e-MTB's as 'motorised', and they are only permitted where motorised vehicles are allowed. This means that trail network near your house might not be open for electric mountain bikes, however, some local and state land management agencies have made exceptions.  

Our friends over at People for Bikes and MTB project have put together a pretty comprehensive map of trails where electric mountain bikes are permitted. You can see the full map here.

Australia

In Australia, e-bikes are split into throttle operated and pedal assist. Both systems must be limited to 25kph, and the throttle-operated motors can only output 200 watts while pedal assist is legal up to 250 watts. Anything that exceeds these figures is considered a motorbike and must be licensed and insured.

E-MTB motors and batteries

While electric bike motors can be placed in either wheel or at the bottom bracket, e-MTBs should have a mid-drive motor system. The motor and battery are the heaviest parts on the bike, and with this weight between the wheels and close to the ground, it doesn't throw your centre of gravity out of whack.

Mid-motor systems also perform more efficiently at a lower cadence and have sensors to measure how hard you're pedalling to tailor the level of torque and maintain grip. The motors are optimised for trail use, with a few levels of assistance; ranging from low-watt 'eco' modes to gradient flattening 'turbo'.

Batteries will be described in Watt-hours or WH,  taking both output and capacity into account — a bigger number means the battery will take you farther on a single charge, but those with more capacity are heavier.

Frame and components

Many e-mountain bikes come with robust aluminium framesets, but brands are rolling out more carbon options as they get the hang of this new segment of bikes. As with analogue mountain bikes, full suspension reigns supreme when it comes to e-MTBs, and with the right suspension tune, the extra weight can improve descending. Look for robust suspension and a fork with at least 34mm stanchions.

With the extra weight from the motor and battery, it takes considerably more force to slow an e-MTB down, and when you're hurtling toward an unsuspecting hiker or a hairpin corner, you're going to want four-piston brakes and 200mm rotors.

The additional weight also means the wheels will be built solid, with more spokes and wrapped in 2.5in (or bigger) tubeless tyres. With rolling resistance being less of a consideration, manufacturers opt for puncture-resistant casings and more aggressive tread. 

Rocky Mountain Altitude Powerplay Alloy 50

Rocky Mountain Altitude Powerplay Alloy 50

As close to a MTB feel as you can get

Rear Travel: 150mm | Frame material: Aluminium | Drive system: Rocky Mountain Dyname 3.0 | Wheel size: 27.5in

Motor components available at bike shops
Geometry matches the non-assisted version 
Underforked
Battery not removable 

Rocky Mountain was somewhat late launching its first e-MTB, but that's because they designed their own drive system. Based around a standard crank and bottom bracket, Rocky Mountain fashioned its Powerplay drive system to use parts which are readily available at any bike shop.

Made with aluminium, the frame mirrors the geometry of the non-powered Altitude, including the short-for-an-e-bike 425mm chainstay. The Altitude Powerplay is powered by a 500wh battery, and gets the Ride9 flip-chip allowing for three variations of the geometry - the steep position makes for a 65-degree head angle and 74-degree seat angle (size M).

At the back, Altitude gets a 150mm RockShox Deluxe Select +, and at the front is a 160mm Yari RC fork.

Trek Powerfly FS 5

For those looking to try an e-MTB

Rear Travel: 130mm | Frame material: Aluminium | Drive system: Bosch Performance CX | Wheel size: 27.5in

Bosch CX motor
RIB battery 
 Long chainstays

Trek offers the Powerfly in hardtail, long and short travel versions; the FS5 is the latter with 130mm of squish at the back. Last year Trek updated the battery from the traditional bottom-loaded version to a side load 'Removable Integrated Battery' or RIB. The advantage here is the Bosch Powertube 500Wh battery isn't in the direct firing line of debris launched off the front wheel, and it's a bit easier to install.

At the cranks, Trek has specced a Bosch Performance CX motor which offers 75nm of torque, and the Purion display offers 'intelligent e-MTB' mode which tailors the output to the terrain at hand. 

Serving as the entry-level full suspension e-MTB in Trek's range, the PowerFly FS 5 rolls on 27.5in wheels and tyres, has a Shimano Deore 10-speed drivetrain, and a RockShox Recon RL fork. 

Commencal Meta Power 29 Ride

Commencal Meta Power 29 Ride

It's not pretty, but it rides well

Rear Travel: 140mm | Frame material: Aluminium | Drive system: Shimano STEPS E8000 | Wheel size: 29in

Value for money
Eats rock gardens for breakfast 
Lacking battery integration 

Commencal has long been delivering bikes that well outperform their price tag (especially when the trail points down), and the Meta Power 29 is no exception. For 2020 the geometry gets longer, lower and slacker, and if you can stay off the brakes, it will hang with anything. 

With the comparatively low price tag, the Meta Power 29 Ride comes with a 140mm RockShox Deluxe Select + rear shock, a 160mm Lyrik Select fork, SRAM NX Eagle drivetrain with Guide RE brakes and 200mm rotors doing the stopping. 

The Meta Power 29 Ride has a Shimano STEPS E8000 drive system but lacks the slick integration of its more expensive compatriots with the battery occupying the space for a water bottle.

Giant Trance E+ 1 Pro

Giant Trance E+ 1 Pro

Best for those looking to ride all-day

Rear Travel: 140mm | Frame material: Aluminium | Drive system: Giant SyncDrive Pro by Yamaha | Wheel size: 27.5in

Value for money
Good range 
Sluggish handling
Weight 

Putting out up to 80nm of torque and a claimed 360 per cent of pedalling input Giant has tuned the Yamaha motor attached to the Trance E+ 1 Pro to provide consistent power, even at low cadence.

The frame itself is made from Giant's ALUXX SL alloy with a 500WH battery integrated neatly into the down tube. At the back, the Maestro suspension design is supple, it simply glides over the small stuff, and the 140mm Fox 36 fork doesn't get squirmy under pressure. Rolling on 27.5 inch wheels and tyres, the smaller hoops help to lessen the weightiness of the bike.

Finished with a SRAM GX Eagle 12-speed drivetrain, and Code R brakes, Giant also supplies the Trance E+ 1 Pro with tubeless valves and rim strips factory-installed - they even include sealant so you can take full advantage of the Maxxis Minion tyres. 

Scott Genius eRide 920

Scott Genius eRide 920

Best for those who don't want to wait for the shuttle

Rear Travel: 150mm | Frame material: Aluminium | Drive system: Shimano STEPS E8000 | Wheel size: 27.5in or 29in

Trail mode assistance
Long and slack geometry 
Twinlock suspension overly complex 

The analogue Genius is a bike that loves to ride at full-send, and the electric version is no different. Depending on where you live, the Scott Genius eRide will either come with 29er or 650b wheels and tyres, although should you want to swap, a flip-chip allows for the necessary change in geometry. With the big wheels, plenty of travel and the heft of the motor, the Genius eRide is a veritable sled, allowing you to point it through nasty terrain and come out the bottom upright. 

The Shimano STEPS drivetrain gives you upto 250watts of assistance and has three modes, Eco, Trail and Boost. With up to 70nm of Torque, Trail mode gives you every newton-metre available, but dials back the watts to extend battery life.

The Fox suspension is paired to Scott's TwinLock dampening remote, which allows you to cycle the damper from closed, to half and fully open without compromising grip on the bars. But, when you add in a shifter, brakes and dropper remote, it creates quite a busy cockpit.

Battery removal

Pivot's new Shuttle is the pinnacle of e-MTB's, with a high-end carbon frame, Kashima coated Fox Factory suspension, and Shimano XTR. The bike can take 29in wheels and tyres or 650b with a 3in tyre — you could even mix wheel sizes to go full enduro. The Shuttle gets a DW-link rear suspension setup for best in class pedalling and traction, with a 140mm rear shock, which is mated with a Fox 36 160mm fork at the front. 

Tipping the scales at a little over 20kg, the Shuttle comes with a STEPS E-8000 drive unit and a 504Wh battery. You'll need an Allen key to remove the cover, but Pivot say it allowed them to create a stiffer downtube.

Norco Sight VLT 2

Rated at 630Wh, the Norco Sight VLT 2 has one of the more powerful batteries in the segment

Norco Sight VLT 2

Nimble and techy

Rear Travel: 150mm | Frame material: Carbon | Drive system: Shimano STEPS E8000 | Wheel size: 27.5in

Handling
Aesthetics
Range 
No bottle cage mount
Battery not removable 

The Sight VLT 2 looks just like its analogue cousin, with only a slight variation in the geometry; the BB is a bit higher, the reach is a touch longer, but the chainstays are the same length. 

Using a Shimano STEPS E8000 drive unit, Norco has opted for a 630Wh battery over the typical 500Wh, and integrated it cleanly into the down tube — though it's not removable. The STEPS motor provides plenty of power that kicks in without the jolt of some systems and is manageable even in turbo mode trying to navigate tight singletrack.

Specced with Sram Eagle NX 12-speed drivetrain, the Guide brakes offer plenty of power and modulation with four positions and 200mm rotors. The Sight VTL also gets RockShox suspension with the base tune customised for the added forces that come with an e-bike. 

YT Decoy 29 CF Pro

Business in the front, party in the back

Rear Travel: 165mm | Frame material: Carbon | Drive system: Shimano STEPS E8000 | Wheel size: 27.5in and 29in

Suspension
Gravity focused geometry
Mixed wheel size 
STEPS remote not very ergonomic

YT took a slightly different approach launching its first electric mountain bike. Instead of aiming to make the most powerful, or the lightest bike on the market, instead, they sought to make the best gravity e-MTB — a point they drove home in the launch video showing Adolf Silva making absolute mincemeat of a downhill track before sending a double backflip.  

With 165mm of rear travel and a 160mm fork, the Decoy borrows a lot of its geometry from the Capra enduro bike, but YT has lowered the BB which in-turn creates a lower centre of gravity. The frame is carbon and sees YT's Virtual 4 Link suspension, designed to have a sensitive beginning, supportive mid-stroke, and progressive end as you move through the travel. 

Using a STEPS E8000 Motor, YT says it designed its own 540Wh battery using the same technology you see in Tesla cars. The YT comes with mixed wheel sizes, with the front wheel offering roll over and control and the rear, specced with a 2.8in tyre offering grip and stability.
