The world of electric mountain bikes has long been dominated by eye-watering price tags. Walk into any mainstream bike shop, and a decent full-suspension e-MTB will easily set you back £3,000 or more. So when a new model pops up direct from the manufacturer for just £776 / €889, it’s bound to turn heads. Enter the Touroll U3 Pro – a full-suspension electric mountain bike that promises trail-capable features at a price that almost seems too good to be true.
But as anyone who has ever shopped for budget e-bikes knows, the fine print matters. While the U3 Pro looks the part with its chunky 29” tyres and dual suspension, a closer inspection reveals some significant compromises. Let’s break down exactly what you get for your money – and whether those trade-offs are worth making.
Pricing and Availability: Direct-to-Consumer Savings
Touroll is selling the U3 Pro exclusively through its official online store, cutting out the middleman to keep costs low. At the time of writing, the bike is priced at £776 for UK customers and €889 for European buyers. For that sum, you’re getting a full-suspension frame – something that’s virtually unheard of in this price bracket. Most sub-£1,000 e-bikes opt for a rigid or hardtail design to save on manufacturing complexity.
However, buying direct also means you won’t get the hands-on support of a local dealer. Assembly, tuning, and warranty claims will be down to you or a third-party bike shop. If you’re comfortable with a bit of DIY, that might be a fair trade for the savings.
Hub Motor vs. Mid-Drive: The Performance Debate
The Touroll U3 Pro is powered by a rear hub motor that delivers a claimed maximum torque of 70 Nm. On paper, that’s enough to tackle moderate hills and provide a decent boost on flat terrain. But there’s a reason most serious electric mountain bikes use mid-drive motors instead.
Mid-drive systems place the motor at the bike’s bottom bracket, keeping weight low and centred. That improves handling, especially on technical trails where balance is everything. Hub motors, by contrast, add unsprung mass to the rear wheel, which can affect traction and suspension response. They’re fine for commuting or light off-road use, but for genuine mountain biking, it’s a noticeable drawback.
Perhaps more concerning is the type of sensor the U3 Pro uses. The product advertising makes no mention of a torque sensor, which strongly suggests the bike relies on a cadence sensor. For those unfamiliar: a cadence sensor simply detects that the pedals are turning and then delivers a fixed amount of power. A torque sensor, on the other hand, measures how hard you’re pushing and adjusts assistance accordingly.
On a mountain bike, the difference is night and day. Cadence-based systems can feel jerky and unpredictable – especially when you’re starting on an incline. Imagine tackling a steep, loose climb: you push down on the pedals, the bike hesitates, then suddenly lurches forward with more power than you expected. That kind of abrupt delivery can break traction or throw off your balance, turning a tricky section into a potentially unsafe situation. For casual dirt paths and fire roads, it’s manageable. For technical singletrack? Less so.
Suspension and Frame: The Full-Package Appeal
The U3 Pro does score points for its suspension setup. It comes with a suspension fork up front and a rear shock, both featuring lockout functionality. That means you can stiffen the suspension for climbs or smooth pavement, then open it up for descents and bumpy trails. Lockout is a genuinely useful feature that even some more expensive bikes omit.
That said, we don’t yet know the brand or quality of the suspension components. At this price point, you’re likely looking at entry-level coils or basic air shocks with limited adjustability. They’ll take the edge off small bumps and ruts, but don’t expect the plush, small-bump sensitivity of a Fox or RockShox unit.
The frame itself appears to be a conventional aluminium hardtail-with-linkage design. Touroll has at least avoided the trap of using a step-through or commuter-style geometry – the U3 Pro looks properly aggressive, with a relatively slack head angle and plenty of standover clearance.
Battery and Range: Big Capacity, Old-School Placement
One of the more surprising specs is the 720 Wh battery. That’s a genuinely large capacity – many mainstream e-MTBs ship with 500–600 Wh packs. In theory, 720 Wh should give you a serious range, potentially 40–60 miles depending on terrain and assist level. But before you get too excited, notice how the battery is mounted.
It’s not integrated into the downtube. Instead, it’s an external unit, likely bolted to the frame or slotted into a rear carrier. This is a throwback to earlier generations of e-bikes. Why does it matter? First, an external battery raises the bike’s centre of gravity, making handling feel more top-heavy. Second, it’s more exposed to dirt, water, and impacts – not ideal for an off-road machine. And third, it simply looks dated.
For some riders, especially those who prioritise range over aesthetics, this might not be a deal-breaker. But in 2026, most buyers expect a sleek, integrated battery that disappears into the frame. Touroll has clearly made a cost-saving choice here.
Brakes, Drivetrain, and Tyres: A Mixed Bag
Stopping power comes from hydraulic disc brakes with 180 mm rotors front and rear. That’s actually a pleasant surprise. Hydraulic brakes offer better modulation and require less hand effort than mechanical discs. At this price, many budget e-bikes still skimp with mechanical calipers. Touroll deserves credit for going hydraulic.
The drivetrain is a 7-speed Shimano derailleur. Nothing fancy – it’s likely an entry-level Tourney or Altus group. But seven speeds are perfectly adequate for an e-bike, where the motor does most of the climbing work. Shifts should be reliable if not lightning-fast.
Tyres measure 29” x 2.4” with what appears to be a decent, knobby tread pattern. That’s a proper mountain bike size – the large diameter rolls over obstacles well, and the width provides decent float in loose conditions. However, budget tyres often use hard rubber compounds that lack grip on wet roots or rocks. We’d recommend inspecting the sidewalls for any brand markings; if they’re generic, you may want to budget for an upgrade later.

Who Is the Touroll U3 Pro For?
Let’s be realistic. If you’re an experienced mountain biker who rides aggressive trails, jumps, or rocky descents, this is not the bike for you. The hub motor, cadence sensor, and entry-level suspension will leave you frustrated and potentially unsafe.
But if you’re a casual rider, a budget-conscious commuter who also enjoys fire roads, or someone looking for a do-it-all e-bike that won’t break the bank, the U3 Pro starts to make more sense. Think of it as a “light trail” or “gravel-plus” machine. It’s also a great option for converting a non-cycling friend or family member who wants to explore off-pavement without spending a fortune.
The external battery, while inelegant, is at least easy to remove for charging or replacement. And the hydraulic brakes are a genuine win. For £776, you’re getting full suspension, a big battery, and reasonable component choices where it counts.
Final Verdict: Compromises You Can Live With – Or Not?
| Pros | Cons |
|---|---|
| Unbeatable price for full-suspension e-MTB | Hub motor adds rear weight, less responsive |
| Large 720 Wh battery for extended range | External battery looks dated, raises COG |
| Hydraulic disc brakes with 180 mm rotors | Likely cadence sensor (jerky power delivery) |
| Suspension fork and rear shock with lockout | Unknown quality of suspension components |
| 29” x 2.4” knobby tyres | No torque sensor for natural riding feel |
| Shimano 7-speed drivetrain | Direct-to-consumer = no local dealer support |
The Touroll U3 Pro is a classic case of “you get what you pay for” – but also a little bit more. It delivers on its headline promises: full suspension, hydraulic brakes, and a very large battery for under £800. The downsides – hub motor, cadence sensor, external battery – are real, but not necessarily fatal for the right rider.
If you understand the limitations and ride within them, this bike could be a fantastic value gateway into electric mountain biking. Just don’t expect it to keep up with a £5,000 Specialized Turbo Levo on black diamond trails. For gentle woods, canal paths, and country lanes with occasional bumps, the U3 Pro might just be the bargain of the year.
