The best full-suspension eMTBs under £4,000 are now far more convincing than they used to be. This budget still involves compromises, but it can now buy a proper trail-ready electric mountain bike with a recognised mid-drive motor, useful battery capacity, hydraulic disc brakes and suspension that makes rough UK trails more manageable.
This is the price point where full-suspension eMTBs start to become realistic for more riders. You are not yet in flagship territory, and you should not expect top-end Fox Factory suspension or wireless drivetrains, but the best full-suspension eMTBs under £4,000 can handle trail centres, bridleways, woodland singletrack, steep climbs and rougher natural routes without feeling like cheap e-bikes dressed up as mountain bikes.
The key is choosing the right compromise. A cheaper full-suspension eMTB may give you comfort and traction, but a smaller battery or basic brakes. A bike closer to £4,000 may bring a Bosch CX motor, an 800Wh battery, better geometry or more suspension travel, but it will usually be heavier and more serious. If you want to compare against cheaper options, read our guide to the best eMTBs under £3,000. If you want the wider market view, see our best full-suspension eMTB 2026 guide.

The best full-suspension eMTBs under £4,000
Decathlon Rockrider E-EXPL 520 S
£2,499.99 (RRP £2,999)
The Decathlon Rockrider E-EXPL 520 S is the entry point for this guide and still one of the most important bikes here. It proves that the best full-suspension eMTBs under £4,000 do not all need to sit near the top of the budget. With 140mm travel front and rear, a Brose T motor with 70Nm of torque and a 500Wh battery, it gives newer riders a proper route into full-suspension eMTB riding without a huge spend.
This is not an enduro bike, and it should not be treated like one. The E-EXPL 520 S is best for trail centres, rougher bridleways, forest routes and riders who want comfort and grip rather than maximum battery size. The 500Wh battery is smaller than several hardtails at similar money, but the rear suspension, dropper post and 203mm brake rotors make it more confidence-inspiring on rough ground.
Pros
Very accessible price for a proper full-suspension eMTB
140mm travel front and rear adds useful comfort and traction
Brose mid-drive motor gives smooth climbing support
Cons
500Wh battery is smaller than many hardtails at similar money
Specifications
Frame: 6061 aluminium full-suspension frame, 140mm rear travel
Motor: Brose Drive T aluminium, 70Nm
Battery: 500Wh integrated removable battery
Fork: X-Fusion McQueen R, 140mm travel
Shock: X-Fusion Pro R, 140mm rear travel platform
Tyres: Rockrider Grip 500, 29×2.4in
Drivetrain: Microshift Advent X 1×10
Brakes: Tektro hydraulic disc brakes, 203mm rotors
Merida eONE-FORTY 400 SE
£2,999 (RRP £4,400)
The Merida eONE-FORTY 400 SE is a strong step up if you want a Shimano-powered full-suspension eMTB below £3,000. It uses a Shimano EP6 motor with 85Nm of torque, a 630Wh battery and Merida’s eONE-FORTY trail platform. That makes it a useful option for riders who want more battery and a more established trail-bike feel than the Decathlon, while still staying well below the £4,000 ceiling.
The eONE-FORTY 400 SE is more trail-focused than gravity-focused. Its mixed-wheel setup, roughly 140mm front and 133mm rear travel, dropper post and Shimano hydraulic brakes make sense for red trail-centre loops, woodland singletrack, rolling natural trails and longer mixed rides. It is not as plush or aggressive as the eONE-SIXTY or Cube ONE77, but that is part of the appeal if you want a manageable everyday full-suspension eMTB.
Pros
Shimano EP6 motor and 630Wh battery at a strong price
Manageable trail geometry suits varied UK riding
Good choice for riders stepping up from a hardtail
Cons
More all-round trail bike than aggressive enduro machine
Specifications
Frame: Merida eONE-FORTY Lite aluminium full-suspension frame
Motor: Shimano EP6, 85Nm
Battery: Shimano 630Wh internal battery
Fork: SR Suntour air fork, 140mm travel
Shock: SR Suntour rear shock, approx. 133mm rear travel
Tyres: Mixed wheel trail tyre package
Drivetrain: Shimano CUES 1×10
Brakes: Shimano hydraulic disc brakes
Cube Stereo Hybrid ONE44 Pro 800
£3,499
The Cube Stereo Hybrid ONE44 Pro 800 is one of the best full-suspension eMTBs under £4,000 for riders who want a sensible Bosch-powered trail bike. It has the latest Bosch Performance Line CX motor, a huge 800Wh PowerTube battery, 140mm travel front and rear, Shimano 4-piston brakes and a dropper post. That is a very complete package for regular UK trail riding.
The ONE44 Pro 800 is not trying to be a bike-park weapon. Its strength is balance. The 140mm travel gives more comfort and control than a hardtail, while the 800Wh battery gives far more range confidence than most budget full-suspension eMTBs. It suits trail centres, forest singletrack, steep bridleways and long weekend rides. The SR Suntour suspension is functional rather than premium, but the Bosch system and overall build make it an easy bike to justify.
Pros
Bosch CX motor and 800Wh battery at a strong price
140mm travel is ideal for everyday trail riding
Shimano 4-piston brakes and dropper post add real trail value
Cons
Suspension is useful rather than high-end
Specifications
Frame: Cube Aluminium Superlite full-suspension frame, 140mm rear travel
Motor: Bosch Performance Line CX smart system
Battery: Bosch PowerTube 800Wh
Fork: SR Suntour XCR36 2CR Air, 140mm travel
Shock: SR Suntour EdgeX R
Tyres: Schwalbe Nobby Nic, 2.6in
Drivetrain: Shimano XT / Deore 12-speed
Brakes: Shimano MT420 4-piston hydraulic disc brakes, 203mm rotors
Giant Stance E+ 2
£3,499
The Giant Stance E+ 2 is a good option if you want a full-suspension eMTB that feels approachable rather than overbuilt. It uses Giant’s SyncDrive Sport3 motor with 85Nm of torque, a 625Wh EnergyPak battery, 150mm front travel and 140mm rear travel. That makes it more capable than older Stance E+ models and a useful choice for riders who want trail progression without jumping straight into a big enduro bike.
The key strength is usability. The Stance E+ 2 has modern trail geometry, 29in wheels, Maxxis Minion tyres, a dropper post and Tektro Orion 4-piston brakes. It should suit riders who want to ride further, climb more easily and start taking on rougher trail-centre routes with more confidence. The 625Wh battery is smaller than the 800Wh Bosch bikes in this guide, but it keeps the bike from becoming too much of a brute.
Pros
Smooth Giant motor support with 85Nm torque
150/140mm travel suits trail progression
4-piston brakes, dropper post and Maxxis tyres are useful trail features
Cons
625Wh battery is not as large as several rivals here
Specifications
Frame: Giant ALUXX SL aluminium full-suspension frame, 140mm rear travel
Motor: Giant SyncDrive Sport3, 85Nm
Battery: Giant EnergyPak 625Wh
Fork: Giant STL 36 Air, 150mm travel
Shock: Giant Crest FloTrac
Tyres: Maxxis Minion DHF front and Maxxis Dissector rear
Drivetrain: Shimano CUES LinkGlide 1×10
Brakes: Tektro Orion 4-piston hydraulic disc brakes
Merida eONE-FORTY Lite 675
£3,599 (RRP £5,200)
The Merida eONE-FORTY Lite 675 is the stronger Merida trail option in this guide. It uses the Shimano EP801 motor, a large 750Wh removable battery, 150mm front travel and 143mm rear travel. If you like the eONE-FORTY idea but want more range and a more premium motor than the 400 SE, this is the model to look at.
This is one of the best full-suspension eMTBs under £4,000 if your riding involves longer days, winter conditions or repeated climbs. The 750Wh battery gives it a range advantage over many mid-price trail eMTBs, while the EP801 motor keeps the assistance smooth and familiar. The specification is still value-conscious in places, but the frame, battery and motor package are strong for the money.
Pros
Shimano EP801 motor and 750Wh battery below £4,000
Good travel range for UK trail centres and natural singletrack
Removable battery is practical for charging and storage
Cons
Discounted stock may mean limited size and colour choice
Specifications
Frame: Merida eONE-FORTY Lite aluminium full-suspension frame
Motor: Shimano EP801, 85Nm
Battery: 750Wh removable integrated battery
Fork: SR Suntour Aion, 150mm travel
Shock: RockShox Super Deluxe Select
Tyres: Maxxis trail tyre package
Drivetrain: SRAM NX Eagle 12-speed
Brakes: Hydraulic disc brakes, model dependent
Trek Rail+ 5 Gen 5
£3,479 (RRP £4,250)
The Trek Rail+ 5 Gen 5 is where this guide starts to move into proper long-travel territory. It has a Bosch Performance Line CX motor, an 800Wh removable battery and 160mm of suspension travel. That gives it a much bigger riding envelope than the more trail-focused bikes above it. It is built for riders who want to climb back up and repeat rougher descents, not just smooth out easy forest loops.
For the money, the core package is excellent. You get Trek’s aluminium Rail+ frame, adjustable geometry, a RockShox fork and shock, Shimano Deore 12-speed drivetrain, dropper post and 4-piston hydraulic disc brakes. The components are workhorse rather than flashy, but the battery, motor and chassis are strong. If you want one of the best full-suspension eMTBs under £4,000 for trail progression, the Rail+ 5 is a serious contender.
Pros
Bosch CX motor and removable 800Wh battery
160mm travel gives far more descending confidence
Adjustable geometry and upgradeable build make it a strong long-term platform
Cons
More bike and more weight than some riders need
Specifications
Frame: Trek Alpha Platinum Aluminium full-suspension frame, 160mm rear travel
Motor: Bosch Performance Line CX smart system
Battery: Bosch PowerTube 800Wh, removable
Fork: RockShox Psylo Gold RC, 160mm travel
Shock: RockShox Deluxe Select+ RT
Tyres: Bontrager Gunnison Elite XR, mixed wheel setup depending on size
Drivetrain: Shimano Deore M6100 1×12
Brakes: 4-piston hydraulic disc brakes
Haibike ALLMTN 2
£3,899
The Haibike ALLMTN 2 is a strong choice if you want a Bosch-powered all-mountain eMTB rather than a shorter-travel trail bike. It has 160mm travel front and rear, a Bosch Performance Line CX motor, an 800Wh PowerTube battery and a mixed-wheel setup. That gives it the support, grip and suspension travel needed for steeper trail centres and rougher natural riding.
The ALLMTN 2 is not as polished as some premium Haibike models, but the build is well judged for the money. Suntour suspension keeps the price under control, while Shimano Deore 12-speed, SRAM DB4 4-piston brakes, Continental Kryptotal tyres and a dropper post give it the parts it needs for proper riding. If you want big range and a confident 160mm chassis without spending beyond £4,000, it is a very relevant option.
Pros
Bosch CX motor and 800Wh battery
160mm travel front and rear suits all-mountain riding
4-piston brakes and Continental tyres are good trail choices
Cons
Suspension is capable, but not premium
Specifications
Frame: Haibike aluminium full-suspension frame
Motor: Bosch Performance Line CX, 85Nm, update dependent
Battery: Bosch PowerTube 800Wh
Fork: SR Suntour Zeron36X-Boost, 160mm travel
Shock: SR Suntour EDGE-X R
Tyres: Continental Kryptotal front and rear, mixed wheel setup
Drivetrain: Shimano Deore 1×12
Brakes: SRAM DB4 Stealth 4-piston hydraulic disc brakes
Cube Stereo Hybrid ONE77 HPC Race 800
£3,999
The Cube Stereo Hybrid ONE77 HPC Race 800 sits right at the top of the budget and brings the most gravity-focused Cube option into this guide. It has a C:62 carbon mainframe, aluminium rear triangle, Bosch Performance Line CX motor, 800Wh battery, 170mm travel front and rear, mullet wheels and 4-piston brakes. For a bike sitting just under £4,000, that is a serious specification.
This is the Cube to choose if the ONE44 Pro 800 looks too trail-focused for your riding. The ONE77 is more suited to steep terrain, bike-park days, rough trail centres and riders who want more travel in reserve. The SR Suntour Aion 38X fork and TRIAir rear shock are not top-end suspension parts, but they give the bike proper travel depth. If you ride harder terrain and still want Bosch CX and an 800Wh battery, this is one of the strongest options here.
Pros
Carbon mainframe with Bosch CX and 800Wh battery
170mm travel front and rear gives proper descending capability
Mullet setup, big tyres and 4-piston brakes suit rougher trail
Cons
Long-travel setup is overkill for gentler riders
Specifications
Frame: Cube C:62 carbon mainframe with aluminium rear triangle, 170mm rear travel
Motor: Bosch Performance Line CX smart system
Battery: Bosch PowerTube 800Wh
Fork: SR Suntour Aion 38X Air, 170mm travel
Shock: SR Suntour TRIAir 2CR
Tyres: Schwalbe Magic Mary front and Big Betty rear
Drivetrain: Shimano XT / Deore 12-speed
Brakes: Magura Louise 4-piston hydraulic disc brakes, 203mm rotors
Liv Embolden E+ 1
£3,999
The Liv Embolden E+ 1 is the women-specific full-suspension eMTB in this guide, and it earns its place on more than fit alone. It has a SyncDrive Pro 3X motor with up to 100Nm of torque, an 800Wh battery, 150mm front travel and 140mm rear travel. Those numbers put it right in the mix with the best full-suspension eMTBs under £4,000, especially for riders who want a bike designed around Liv’s sizing and contact-point approach.
The Embolden E+ 1 is best for riders who want a confident trail bike rather than a huge enduro machine. The 800Wh battery is a major strength, giving plenty of range for longer UK rides, while the motor has more punch than many mid-price eMTBs. It is still a powerful and relatively heavy full-suspension bike, so new riders should take time with setup, tyre pressures and support modes. For the right rider, it is one of the most complete women-specific eMTBs below £4,000.
Pros
Women-specific full-suspension eMTB with strong trail capability
100Nm motor and 800Wh battery give serious support and range
150/140mm travel is well matched to UK trail riding
Cons
Powerful full-suspension build may feel like a lot for absolute beginners
Specifications
Frame: Liv ALUXX SL aluminium full-suspension frame, 140mm rear travel
Motor: Giant SyncDrive Pro 3X, up to 100Nm
Battery: Giant EnergyPak 800Wh
Fork: Giant STL 36 Air, 150mm travel
Shock: Giant Crest FloTrac
Tyres: Maxxis Minion DHF front and Maxxis Dissector rear
Drivetrain: Shimano CUES LinkGlide 1×10
Brakes: Shimano Deore 4-piston hydraulic disc brakes
What should you expect from a full-suspension eMTB under £4,000?
The best full-suspension eMTBs under £4,000 are good enough for real trail riding, but they are still built to a price. Expect aluminium frames on most models, value-focused suspension, dependable rather than exotic drivetrains, and brakes that may be the first place heavier or faster riders consider upgrading.
Battery size varies a lot. The Decathlon uses 500Wh, which is fine for shorter rides but not ideal for big winter loops. The Merida eONE-FORTY 400 SE has 630Wh, while the Cube, Trek, Haibike and Liv options bring 800Wh batteries into the mix. If range matters more than low weight, aim for the bigger battery. If handling and price matter more, a smaller battery can still make sense.
Is 140mm, 150mm, 160mm or 170mm travel best?
For most riders, 140mm to 150mm is the sweet spot. It gives enough comfort and traction for UK trail centres and natural singletrack without making the bike feel too long, heavy or sluggish. That is where bikes such as the Cube Stereo Hybrid ONE44 Pro 800, Giant Stance E+ 2, Merida eONE-FORTY Lite 675 and Liv Embolden E+ 1 make sense.
Go to 160mm or 170mm if your riding is steeper, rougher or more gravity-focused. The Trek Rail+ 5, Haibike ALLMTN 2 and Cube Stereo Hybrid ONE77 HPC Race 800 are better choices for bike-park days, repeated rough descents and bigger trail-centre riding. They are not automatically better bikes. They are better for harder terrain.
Frequently Asked Questions
What is the best full-suspension eMTB under £4,000?
The best full-suspension eMTB under £4,000 for most riders is likely to be the Cube Stereo Hybrid ONE44 Pro 800 if you want a balanced trail bike, or the Trek Rail+ 5 Gen 5 if you want more travel and descending confidence. The Decathlon Rockrider E-EXPL 520 S is the best low-cost option, while the Cube Stereo Hybrid ONE77 HPC Race 800 is the strongest long-travel pick.
Can you get a good full-suspension eMTB under £4,000?
Yes, you can get a good full-suspension eMTB under £4,000 if you choose carefully. The best bikes in this price range now include Bosch CX, Shimano EP6 or EP801, Brose and Giant motor systems, with battery sizes from 500Wh to 800Wh. The key is matching the bike to your riding rather than simply buying the one with the most travel.
Is an 800Wh battery worth it?
An 800Wh battery is worth it if you ride long routes, winter trails, hilly areas or repeated trail-centre climbs. It adds weight, but gives much more range confidence. If your rides are shorter or you value lower cost, a 500Wh to 630Wh battery can still work well.
Should I choose Bosch, Shimano, Brose or Giant?
Bosch is the safest option for dealer support and battery ecosystem, Shimano often gives a natural ride feel, Brose is smooth and quiet, and Giant’s SyncDrive system offers strong power and good integration. Do not buy on motor brand alone. The best full-suspension eMTBs under £4,000 are the bikes where the frame, motor, battery, brakes and suspension all make sense together.
Is full suspension worth it on an eMTB?
Full suspension is worth it if you ride rough trails, roots, rocks, trail centres or longer descents where comfort and traction matter. A hardtail can still be better value for smoother bridleways and forest tracks, but a full-suspension eMTB gives more control and reduces fatigue once the terrain gets rough.
What should I upgrade first?
Tyres and brake pads are usually the first upgrades to consider. Many bikes under £4,000 come with good all-round tyres, but wet UK trails often need more aggressive rubber. If the bike has basic brakes or small rotors, stronger pads or larger rotors can also make a big difference to control.
