If you have ever looked at e bike prices and felt a bit lost, you are not alone. You can spend £500 on a basic bike or hand over £20,000 for a dream build, and on paper many of them seem oddly similar. Same travel, same motor, same battery size, even the same frame geometry.
So how do you work out what you are really paying for, and where the sweet spot is between price and performance?
In this guide, built from real-world time at big mountain bike festivals in France and Spain, we will walk through what makes a legit eMTB, where cheap bikes go badly wrong, and which models under about €5,000 genuinely stand out. By the end, you will have a calm, clear way to judge if a bike is worth your money, not just shiny marketing.
eMTB Prices: From £500 “Deals” To 20k Super Bikes
The price range for electric mountain bikes is huge. At one end you have entry-level e bikes around £500 to £1,000. At the other, you have ultra high-end builds near £20,000, with factory suspension, carbon everything, and custom paint.
The confusing part is that many of these bikes share core numbers:
- 150 to 170 millimeters of suspension travel
- The same Bosch, Brose, Shimano, or Avenox mid-drive motor
- Similar battery capacities
- Very close frame geometry
A good example is something like a specialized trail eMTB in a “regular” build versus its S-Works limited version. Same motor, same battery, same geometry. The key differences are frame material, paint, and upgraded parts.
So the big question is not just “how much does it cost?” but “what does that extra money actually change for me on the trail?”
Before getting lost in fancy drivetrains and carbon bars, it helps to look at three bigger factors:
- Motor system quality and tune
- Battery capacity and real-world range
- How well the whole system works together (frame, suspension, components)
Once those are right, the rest becomes much easier to judge.
What Makes a “Legit” eMTB, Not Just Any eBike
At busy events like Roc d’Azur in France or Sea Otter in Girona, you see everything from bargain basement bikes to very polished machines. Over time, a pattern appears. The bikes that hold up in real riding share a few clear traits.
The Core eMTB System
A legit eMTB starts with a good electric system that is designed for off-road use. That means:
- A proven motor and control unit that works well at low speed and on steep terrain.
- A battery matched to the bike’s purpose, not just a random number on a spec sheet.
- A clear display and simple controls you can actually use with gloves on.
All of that has to work together with some efficiency, so you get more ride time and smoother power, not just big peak numbers.
Components And Frame Design That Back It Up
The next layer is the bike itself. Strong parts and smart design turn a motor and battery into a real trail bike.
- Wheels and tires need to be tough enough for real off-road use. Thin, cheap tires are common on budget e bikes and they ruin control.
- Brakes must be powerful and consistent, especially when you add the weight of a motor and battery.
- Drivetrain and cranks should shift cleanly and stand up to the extra torque from the motor.
- Frame geometry and suspension design should help you, not fight you, on climbs and descents.
Here is a simple comparison to show the difference between a basic “cheap” build and a more legit trail-ready setup.
| Area | Very Cheap e Bike | Legit eMTB Under 5k |
|---|---|---|
| Tires | Narrow, thin casing | Wider, stronger casing, real off-road tread |
| Brakes | Weak, basic discs | Hydraulic discs with decent power and control |
| Fork & Shock | “Suspension” in name only | Tunable suspension with real damping |
| Motor / System | Unknown or generic hub drive | Known brand hub or mid-drive with support and service |
| Battery | Small, no real data on cells | Stated capacity and tested range |
| Frame Geometry | One-size or limited sizes | Multiple sizes, trail-focused geometry |
At the Roc d’Azur festival, the difference was obvious when you saw bikes like Decathlon’s Rockrider or Polygon’s mid-drive options parked next to very cheap no-name e bikes. They might look similar from a distance, but ride them back-to-back and you feel it straight away.
If you want an extra view on what “value” can look like on paper versus on dirt, the long-term Rockrider E-ST 100 review on BikeRadar is a helpful read.
Where Ultra-Budget eMTBs Go Wrong
Cheap can be good. Ultra cheap usually is not. After spending time on budget eMTBs over the years, three problem areas keep coming back: comfort, reliability, and safety.
Comfort And Control
Some bargain e bikes actually give you less control rather than more. On paper they look like mountain bikes, but in use they feel more like heavy city bikes with knobbly tires.
Common issues:
- Noisy parts that rattle or even fall off
- Tires that are too thin for stones and roots
- Brakes that fade fast or feel wooden
- Suspension that is really just a spring for looks
You end up fighting the bike instead of focusing on the trail. That gets tiring fast and can be scary if you ride on steep or loose terrain.
Reliability In Real Terrain
Reliability problems tend to show up once you leave smooth paths.
Hub drive e bikes can be fine for light trails and gravel. They work well for gentle adventures, commutes, and country cruising. For that kind of riding, a simple hub motor can give years of use.
As soon as the climbs get steeper and the ground gets rough, a decent mid-drive motor starts to make sense. It puts power through the drivetrain, which:
- Gives better performance uphill
- Helps heavier riders on long, steep tracks
- Handles wet and technical conditions better
Some red flags on very cheap builds:
- Parts literally working loose over a few rides
- Inconsistent power delivery, cutting out under load
- Poor waterproofing around the motor and battery
Safety: The Part You Cannot Ignore
There is one area where cheap should never mean “good enough,” and that is safety. Stories of fires and burnouts from home-built kits and very low-quality batteries are sadly real. These are often kits assembled by people without a background in electrics, then charged in homes and garages.
On a proper, legit eMTB from a known brand, the system has been tested as a whole, not as a box of random parts. That is part of what you are paying for when you buy from brands with proper support.
Hub Drive vs Mid Drive e Bikes
One of the first big choices is motor layout: hub drive or mid drive.
Hub Drive: Simple And Affordable
Rear hub motors keep costs low. Most hub-drive e bikes sit between about £500 and £2,000. They can be a good option if you mainly:
- Ride on towpaths, gravel roads, and smoother tracks
- Want a simple bike for country cruising
- Care more about cost than maximum off-road performance
Hub drives are also easy to live with. Fewer sensors and a simpler layout can mean less hassle day to day.
Mid Drive: Power For Real Trails
Mid-drive systems sit at the bottom bracket and drive the chain. They cost more, but you get:
- Better climbing on steep, technical trails.
- More support for heavier riders and steeper regions.
- More refined control in wet and slippery conditions.
Mid drives also tend to come with larger batteries and better integration. For example, bikes using Bosch systems often come with strong dealer support and a choice of battery sizes. You can see this across brands supported by Bosch and sold through partners such as Canyon’s eMTB range.
If your riding is mostly off-road and you want to ride technical climbs, a mid-drive e bike is usually worth the extra money.
Hardtail vs Full Suspension eMTB
Once you have picked a motor layout, the next big choice is frame type.
When A Hardtail Makes Sense
A hardtail has a suspension fork at the front and a rigid rear end. It is lighter, simpler, and often much cheaper.
A good example is the Decathlon Rockrider ST 505, with a mid-drive motor, 420 Wh battery, and a solid hardtail frame. Bikes like this suit riders who:
- Spend a lot of time on forest roads and smoother singletrack
- Want a lower price but still need a proper eMTB system
- Prefer a simple bike that is easier to maintain
Why Full Suspension Is Worth It For Rough Trails
A full suspension eMTB has front and rear suspension. For off-road use, the benefits are clear:
- More comfort on long rides
- More grip when the trail gets loose or rocky
- Better control on descents and tricky climbs
Some stand-out examples mentioned in the video:
- A Lapierre Overvolt AM 5.8 AL at about £4,600 with a Bosch CX motor, 800 Wh battery, 170 millimeters of travel, RockShox Domain fork, and Shimano Cues drivetrain.
- The Riu Rahu from northern Spain at €2,999, with an earlier Bosch CX motor, 625 Wh battery, about 150 millimeters of travel, Fox 36 fork, and 29 inch wheels.
Both offer serious capability and comfort for real mountain trails. The Riu Rahu is especially interesting because you get full suspension at a price that often only buys you a hardtail.
Tires and shifting matter just as much as the frame. On the Focus Thron, the Shimano Cues derailleur gives crisp shifting and, as a bonus, replacement parts are very affordable. A derailleur around £60 and a cassette under £100 make long-term ownership less painful.
Real-World eMTB Picks Under About 5k
Let’s walk through the specific bikes highlighted, all found at festivals like Roc d’Azur and Sea Otter.
Decathlon Rockrider E-ST 100: Entry-Level Hub Drive
The Rockrider E-ST 100 sits at around €999. Key details:
- Rear hub drive motor
- Around 380 Wh battery
- Hydraulic brakes
- A serviceable front fork
It is a good match for riders who want an affordable e bike for country cruising and mellow trails. If you want more detail from long-term owners, the community-focused E-ST 100 review after 1,000 km on EMTB Forums is quite eye-opening about where its limits are.
Decathlon Mid-Drive Options: Rockrider 520S and ST 505
Decathlon also does more advanced mid-drive eMTBs that still keep prices sensible.
- Rockrider 520S: Full suspension, 500 Wh battery, Brose motor, just over €2,000.
- Rockrider ST 505: Hardtail frame, mid-drive motor, 420 Wh battery, built for hills and adventure.
These bikes show how far you can go with a realistic budget and a focus on the basics: a good motor, a decent battery, and honest component choices.
Polygon Siskiu: Mid-Drive Trail Bike
Polygon’s Siskiu range is a strong example of mid-drive eMTBs under €5,000.
- Prices start around €3,900
- Two versions: one with a Shimano motor and 630 Wh battery, one with Bosch and a 625 Wh battery in the downtube
- Around 150 millimeters of travel
- Solid, sensible component choices
These bikes cover a lot of ground. They are happy on big days out, technical climbs, and proper descents, without hitting silly price tags.
Lapierre Overvolt AM 5.8 AL: Long-Travel, Long-Range
The Lapierre Overvolt AM 5.8 AL is another standout:
- Around £4,600
- Aluminum frame
- Bosch Performance CX motor
- 800 Wh battery
- 170 millimeter travel with a RockShox Domain fork
- Shimano Cues drivetrain
For riders who want big range and big travel without stepping into top-tier pricing, it is a strong package.
Canyon, Riu Rahu, Focus, Superior: Quiet Gems
A few more bikes caught the eye at events.
- Canyon Neuron AL 7: Around €3,799, Bosch motor, trail-ready travel, and good support from both Canyon and Bosch.
- Riu Rahu: €2,999, early Bosch CX motor, 625 Wh battery, 150 millimeters of travel, Fox 36 fork, 29 inch wheels, and a removable battery. Full suspension for the price of many hardtails.
- Focus Thron: Around €3,999, with a very strong spec for the money, including quality suspension, proper tires, and Shimano Cues drivetrain.
- Superior 150 mm bike from Czech Republic: About €4,000, 800 Wh battery, mid-drive motor, four frame sizes, and a clean, modern look. It ticks all three boxes: solid system, smart components, and geometry that works.
These are the sort of bikes that feel “right” when you ride them. The motor, suspension, and frame all work together, so you can just focus on the trail.
Megamo Reason: Price vs Performance Champion
The Megamo Reason from Girona is a very interesting case.
The high-end version has:
- Factory-level suspension
- Carbon frame and carbon components
- Avenox motor with 1,000 W peak power
- 800 Wh battery
The more affordable entry-level Megamo Reason comes in under €5,000, yet uses the same:
- Avenox motor
- 800 Wh battery
- Frame dimensions
That means identical uphill performance to the top model. What you pay extra for at the high end is weight savings, flashier parts, and a bit more polish, not more raw capability on climbs.
This mirrors the early question about a “regular” Levo compared to an S-Works model. Same motor, same battery, same geometry. Once the frame and power system are fixed, expensive parts add finesse more than fundamental performance.
Sizing And Fit: The Most Overlooked “Upgrade”
There is one thing that affects every ride regardless of price: how well the bike fits you.
This is especially important on mid-drive, full suspension bikes. Get the size wrong and even the best eMTB feels awkward, twitchy, or sluggish.
Some brands handle sizing well. Superior, for example, offers four sizes in its 150 millimeter travel eMTB line, so more riders can get a good fit and the right reach.
A few simple checks help here:
- Look for at least three, ideally four, frame sizes in the model you want.
- Whenever you can, test ride at a festival or demo day.
- Pay attention to how the bike feels on climbs and descents, not just in the car park.
Fit also connects to running costs. eMTBs go through parts faster than regular MTBs because of the extra weight and power. Picking bikes with sensibly priced parts, like Shimano Cues on the Focus Thron, means you will spend less in the long run.

Wrapping It Up: Your Calm, Clear eMTB Shortlist
Looking across all these bikes, a pattern forms. You do not need to spend 20k to get a great e bike. You also probably do not want to drop right to the bottom of the price range if you care about off-road performance, comfort, and safety.
Around the €3,000 to €5,000 mark, bikes like the Lapierre Overvolt AM 5.8 AL, Polygon Siskiu, Superior’s 800 Wh trail bike, Riu Rahu, Focus Thron, and the entry-level Megamo Reason deliver a lot of real-world capability. A decade ago, when a base Levo was around £3,500, this level of performance at these prices would have felt wild.
Today, they are simply strong options that let you ride more, ride steeper, and ride farther, without feeling you overpaid for paint and logos.
The main thing to remember: focus on a solid system, smart components, and a bike that fits you. Get those right and you will have an e bike that feels like a partner, not a project.
