The best Bosch CX eMTBs under £5,000 give you a choice of capable trail bikes, long-travel enduro machines and practical hardtails. The right one depends on where you ride: suspension, tyres, fit and battery access matter just as much as the motor badge.
Our overall pick is the Cube Stereo Hybrid ONE44 HPC Race 800. Its balanced trail specification makes sense for a wide range of UK riding. Spend less and the Cannondale Moterra 3 offers particularly strong value; choose the Merida eOne-Eighty FR 600 if bike parks are the priority.

The best Bosch CX eMTBs under £5,000
Cube Stereo Hybrid ONE44 HPC Race 800 2027
Best Overall
£3,999
The ONE44 is our pick for riders whose week mixes trail centres, woodland singletrack and longer hill rides. Its 140mm rear travel and 150mm Fox fork offer a useful middle ground between a hardtail and a bigger enduro bike.
The 2027 Race pairs a carbon mainframe with an aluminium rear triangle, an 800Wh battery and a Kiox 400C display. Shimano four-piston brakes and a wide-range mechanical drivetrain keep the build practical. The broad Nobby Nic tyres suit mixed trails; frequent winter mud riding would justify a more aggressive front tyre.
Pros
Versatile travel for everyday UK trails
Large battery and useful display
Carbon mainframe without spending the full budget
Cons
Tyres favour mixed conditions over deep mud
Specifications
Frame: carbon mainframe, aluminium rear; 140mm rear travel
Motor/battery: Bosch CX; 800Wh
Fork/shock: Fox 36 Rhythm, 150mm; Float Rhythm RC
Gears: Shimano XT rear mech, Deore controls; 12-speed
Brakes: Shimano MT420; 203mm rotors
Cannondale Moterra 3 2026
Best value for all-day trail riding
£3,199
The Moterra 3 puts the money into the parts that matter for long trail rides: an 800Wh battery, full suspension and four-piston brakes. At this price, it is a strong starting point for riders who want Bosch assistance without spending close to £5,000.
Its 29in wheels and 150mm rear travel suit rocky tracks and trail-centre loops. The CUES drivetrain is a sensible everyday choice, while a removable battery helps if you need to charge indoors. The suspension is functional rather than luxurious; choose a more specialised bike if fast, rough descending is your main priority.
Pros
Excellent price for an 800Wh full-suspension bike
Removable battery
Useful trail suspension and braking specification
Cons
Basic suspension dampers compared with more expensive builds
Specifications
Frame: SmartForm C1 aluminium; 150mm rear travel
Motor/battery: Bosch CX; 800Wh
Fork/shock: Psylo Silver RC, 160mm; Deluxe Select
Gears: Shimano CUES U6000, 11-speed
Brakes: Shimano MT520 four-piston
Wheels/tyres: 29in; Continental Kryptotal
Haibike ALLMTN 4 2026
Best value with SRAM Transmission
£3,299 (RRP £3,599)
The ALLMTN 4 makes a convincing case for keeping your budget below £3,500. An 800Wh battery, RockShox suspension and mechanical SRAM Eagle 70 Transmission give it a useful specification for regular trail riding.
The 29in wheels favour carrying speed over roots and rocks, while the 160mm fork leaves room to tackle rougher descents. Continental Kryptotal tyres and four-piston DB8 brakes round out a purposeful build. It is a substantial full-power bike rather than a lightweight option, but the component balance is appealing for riders who want to ride regularly without planning immediate upgrades.
Pros
Strong equipment for the price
800Wh battery
Mechanical T-Type drivetrain
Cons
Trail tyre casings are less supportive than gravity casings
Specifications
Frame: aluminium; 150mm rear travel
Motor/battery: Bosch CX; 800Wh
Fork/shock: Psylo Gold RC, 160mm; Deluxe Select R
Gears: SRAM Eagle 70 T-Type, 12-speed
Brakes: SRAM DB8; 200mm rotors
Wheels: 29in; Purion 200 display
Trek Powerfly+ 6 Gen 5
Best for bridleways and mixed routes
£3,499 (RRP £3,850)
Not every ride needs rear suspension. The Powerfly+ is the sensible option for bridleways, forest roads and smoother trail-centre loops, where its simpler hardtail frame saves on suspension servicing.
The removable 800Wh battery is a major practical benefit for long days and charging away from the bike. A dropper post and four-piston brakes make it more useful off-road than a basic leisure hardtail, while the Shimano Deore/XT gearing gives a broad climbing range.
The trade-off comes on repeated roots and rocks: the rigid rear end demands more from your legs and line choice. Riders spending most of their time on technical descents should consider a full-suspension option. Our best hardtail eMTB guide covers more alternatives.
Pros
Removable 800Wh battery
Lower suspension maintenance
Dropper post and four-piston brakes
Cons
Rigid rear end is tiring on rough descents
Specifications
Frame: Alpha Platinum Aluminium hardtail
Motor/battery: Bosch CX; removable 800Wh RIB 2.0
Fork: RockShox Recon Silver RL, size-dependent travel
Gears: Shimano Deore/XT, 12-speed
Brakes: Shimano MT420 four-piston
Trek Rail+ 5 Gen 5
Best adjustable enduro platform
£3,499
The Rail+ 5 is worth a close look if you want to progress towards rougher trails. Its aluminium frame combines 160mm suspension with geometry adjustments and a removable 800Wh battery. That is a capable foundation for years of riding.
RockShox suspension and Shimano Deore gearing keep the build straightforward. Most sizes use a 29in front wheel and 27.5in rear; the small uses two 27.5in wheels. The smaller rear wheel gives useful clearance on steep terrain, while the removable battery makes charging and transport easier.
There is no need to replace parts before riding it. Set the suspension up properly, find the limits of the standard bike, then spend where your riding demands it. See our full-suspension eMTB guide for more options.
Pros
Adjustable 160mm chassis
Removable battery
Good price for a capable enduro platform
Cons
More bike than gentler routes require
Specifications
Frame: Alpha Platinum Aluminium; ABP; 160mm rear travel
Motor/battery: Bosch CX; removable 800Wh RIB 2.0
Fork/shock: Psylo Gold RC, 160mm; Deluxe Select+ RT
Gears: Shimano Deore, 12-speed
Brakes: Shimano MT420 four-piston
Cube Stereo Hybrid ONE77 HPC Race 800 2026
Best value carbon enduro bike
£3,799 (RRP £3,999)
Choose the ONE77 over the ONE44 when steep descents and rough trails dominate your riding. Its 170mm suspension and mixed wheels give it a more descending-focused brief, while the carbon mainframe and 800Wh battery make an attractive package at this price.
The Suntour suspension keeps costs down without sacrificing travel, and Magura four-piston brakes handle stopping duties. It is a tempting route into a longer-travel eMTB, but the extra suspension is unnecessary for smooth blue routes. Budget for tougher tyre casings if rocky, high-speed riding becomes a regular habit.
Pros
Carbon mainframe at a competitive price
170mm travel at both ends
800Wh battery for repeated climbs
Cons
Performance-series tyres are not heavy-duty gravity casings
Specifications
Frame: carbon mainframe, aluminium rear; 170mm travel
Motor/battery: Bosch CX; 800Wh
Fork/shock: Suntour Aion 38X; TRIAir 2CR
Gears: Shimano XT/Deore, 12-speed
Brakes: Magura Louise; 203mm rotors
Wheels: 29in front, 27.5in rear
Orbea Wild ST H30 Custom 750Wh
Best trail option for a smaller rider
£3,999 (RRP £4,949)
This small-frame Wild ST combines Bosch CX assistance with a 750Wh battery and a trail-focused chassis. It is a useful option for a rider who fits the small and prefers the ST’s shorter-travel approach to the more aggressive Wild enduro bikes.
The aluminium frame uses 29in wheels, a RockShox Psylo Silver fork and a Fox Float Performance shock. Shimano Deore gearing and MT420 four-piston brakes keep replacement parts straightforward. The 750Wh capacity provides substantial energy without making an 800Wh battery a condition of your purchase.
Fit matters more than a discount. Check reach, standover and saddle-height adjustment against a bike you already know; do not size down simply to buy this particular offer.
Pros
750Wh battery in a trail-focused build
Fox rear shock
Straightforward Shimano drivetrain
Cons
This offer is for a small frame only
Specifications
Frame: Orbea Wild Hydro aluminium; 29in wheels; small
Motor/battery: Bosch CX BDU3840; 750Wh
Fork/shock: RockShox Psylo Silver RC; Fox Float Performance
Gears: Shimano Deore M6100, 12-speed, 10–51T
Brakes: Shimano MT420
Controls: System Controller and Mini Remote; 2A charger
Haibike ALLMTN 6
Best for Shimano XT equipment
£4,299 (RRP £4,699)
The ALLMTN 6 is for riders who value a well-equipped aluminium bike over a carbon frame. Shimano XT shifting, Deore four-piston brakes and a RockShox Psylo Gold fork give it a strong everyday trail specification.
The 800Wh battery provides useful capacity for hilly routes, while the Kiox 300 makes ride information easy to see. Compared with the ALLMTN 4, the appeal is its Shimano equipment, upgraded rear shock and separate display. Choose the controls and suspension features you prefer rather than buying on the model number alone.
Pros
XT shifter, rear derailleur and cassette
Deore four-piston brakes
Kiox 300 display
Cons
Less economical than the ALLMTN 4 if you do not need its upgrades
Specifications
Frame: aluminium full suspension
Motor/battery: Bosch CX; 800Wh
Fork/shock: Psylo Gold RC, 160mm; Deluxe Select+ RT
Gears: Shimano XT M8100, 12-speed
Brakes: Deore M6120; 203mm rotors
Tyres: Continental Kryptotal Trail Endurance
Merida eOne-Eighty FR 600
Best for bike parks
From £4,299 (RRP £5,700)
The eOne-Eighty FR 600 is the bike-park specialist. Its 180mm suspension, coil rear shock and gravity-focused tyres make more sense on steep, rough tracks than on a gentle woodland loop.
A DVO Onyx 38 fork works with the Jade X coil shock, while mixed wheels provide front-wheel rollover and rear-wheel clearance. The removable 800Wh battery is useful for riding back to the top under your own power. Shimano CUES gearing keeps the drivetrain practical, and large brake rotors help manage repeated descents.
The £4,299 offer applies to the Short size. Merida’s sizing approach deserves attention: choose reach and handling characteristics that suit you, then check the seatpost adjustment. This is a substantial bike; the ONE44 or Moterra is a better starting point for less demanding terrain.
Pros
180mm travel and coil rear suspension
Supportive gravity tyre specification
Removable 800Wh battery
Cons
Heavy-duty design is excessive for mellow trails
Specifications
Frame: eOne-Eighty LITE I aluminium; 180mm rear travel
Motor/battery: Bosch CX; removable 800Wh
Fork/shock: DVO Onyx 38 D3, 180mm; Jade X Core coil
Gears: Shimano CUES U6000, 10-speed
Brakes: SRAM DB4; 220/200mm rotors
Wheels: 29in front, 27.5in rear
Orbea Wild M20 MX 2026
Best carbon mixed-wheel enduro option
£4,299 (RRP £6,299)
The Wild M20 MX is for riders who put descending first. Its carbon frame, mixed wheels and 170mm suspension make it a more specialised choice than a general-purpose trail bike. The available large-frame build is particularly worth considering for riders who fit that size.
A RockShox ZEB fork and Fox Float X shock provide a sturdy suspension platform, while the 750Wh battery supports the climbs back up. Shimano SLX/Deore gearing keeps the transmission conventional. The MT420 brakes are functional rather than a premium enduro system, so the carbon frame should not be mistaken for a top-spec build throughout.
Pros
Carbon frame with substantial suspension
Mixed-wheel format
750Wh battery
Cons
Available offer is size large
Basic brakes for a descending-focused bike
Specifications
Frame: Orbea Wild OMR carbon; 170mm travel
Motor: Bosch CX
Battery: 750Wh
Fork: ZEB Base, 170mm
Shock: Float X Performance
Wheels: OQUO; 29in front, 27.5in rear
Drivetrain: Shimano SLX/Deore, 12-speed
Brakes: Shimano MT420
How to choose the right Bosch CX eMTB
Match the suspension to your trails
For bridleways, forest roads and smoother singletrack, a hardtail such as the Powerfly+ can keep ownership simple. Rear suspension earns its keep on repeated roots, rocks and rough descents by helping the rear wheel track the ground and reducing fatigue.
A trail bike with roughly 140–150mm of rear travel is a useful starting point for mixed UK riding. The ONE44, Moterra and Wild ST fit this brief. Longer-travel bikes such as the ONE77, Wild M20 MX and eOne-Eighty make more sense when steep or rough descending is the main attraction. Extra travel is not automatically better on every route.
Battery capacity and charging
An 800Wh battery gives more energy capacity than a 750Wh battery, but it cannot guarantee a longer ride across different bikes and riders. Rider weight, elevation, tyre choice, temperature and assistance mode all affect range. Choose capacity around the rides you actually do, with a sensible margin for cold weather and unexpected detours.
Battery access can be more important than a small difference in capacity. If there is no socket where you store the bike, a removable battery makes daily charging much easier. Check the included charger too: a large battery and a low-current charger can mean a longer wait between rides. Our motor and battery explainer covers the main trade-offs.
Look beyond peak torque
Bosch CX assistance helps with steep climbs, but maximum output is not a substitute for suitable gearing and traction. The settings and updates available depend on the exact motor and bike. Use the options offered for your bike in the eBike Flow app, and ask the supplying dealer about compatibility before treating an advertised maximum as a deciding factor.
Start with a manageable level of assistance and increase it where it helps your riding. Stronger assistance can use more battery and put more load through the drivetrain. On slippery climbs, a smooth pedal stroke and an appropriate gear are often more useful than selecting the highest setting.
Brakes, tyres and running costs
A full-power eMTB puts substantial demands on tyres and brakes, especially on long descents. Four-piston brakes and appropriately sized rotors are a good starting point, but setup, pad choice and maintenance still matter. Tyre tread and casing should suit your ground: a lighter trail casing may be pleasant on easier routes, while rocky riding can justify extra support and puncture protection.
Allow room in the budget for a suitable helmet, pedals, tubeless setup and servicing. Suspension bearings, fork and shock services, brake pads and drivetrain wear all form part of ownership. Buying the right complete bike is usually more useful than spending the entire budget on a carbon frame and planning immediate component changes.
Which bike should you buy?
Choose the Cube ONE44 HPC Race 800 for the broadest mix of trail riding. The Cannondale Moterra 3 is the value choice for long days, while the Haibike ALLMTN 4 offers an appealing SRAM Transmission build. The ALLMTN 6 suits riders who prefer Shimano XT controls and a Kiox display.
The Trek Powerfly+ keeps things simpler for smoother routes. The Rail+ 5 provides an adjustable platform for rougher riding. The small Wild ST H30 is worth considering if its fit suits you and you want a trail-focused Orbea with a 750Wh battery.
For descending, compare the Cube ONE77 and Orbea Wild M20 MX. Both use mixed wheels and substantial travel. The Merida goes further towards bike-park use with 180mm suspension and a coil shock. Choose by terrain and fit rather than treating the longest-travel bike as the automatic winner.

Frequently asked questions
What is the best Bosch CX eMTB under £5,000?
The Cube Stereo Hybrid ONE44 HPC Race 800 is our overall choice for mixed UK trail riding. Its combination of suspension, battery capacity and practical components makes it a versatile place to start. Riders focused on bike parks or smoother bridleways should choose a bike suited to those routes instead.
Which is the cheapest full-suspension bike here?
The Cannondale Moterra 3 is the lowest-priced full-suspension selection at £3,199. The Haibike ALLMTN 4 follows at £3,299. Both combine Bosch CX assistance with an 800Wh battery.
Do I need a carbon frame?
No. Frame fit, suspension, brakes and tyres usually have a more direct effect on whether the bike suits your riding. Carbon can offer useful weight and design benefits, but a well-equipped aluminium bike can be a better purchase than a cheaper carbon build with parts you immediately want to replace.
Is an 800Wh battery essential?
No. More capacity is useful for long, hilly rides and regular use of higher assistance. A 750Wh bike may already cover your needs. Battery access, charging arrangements and the overall fit of the bike deserve equal attention.
Verdict
The Cube ONE44 HPC Race 800 is the best all-round starting point in this shortlist, with the Cannondale Moterra 3 standing out on value. Choose the Powerfly+ for simpler routes, the Rail+ or ONE77 for rougher trails, and the Merida for bike parks. Buy the bike that fits your riding and your body; the Bosch motor is there to support that choice.
