ENGWE X26 Dual Battery Review, Long-Range Electric Bike Tested

Looking for an electric bike that can handle long weekend rides and daily commutes without worrying about the next charge? The ENGWE X26 Dual Battery Electric Bike might be the answer. It packs not one but two batteries, huge puncture-resistant tyres, and a powerful motor into a rugged frame. At Biktron, we took it out for a thorough test on British roads and tracks.

We wanted to see if the X26 genuinely delivers 60-mile-plus rides, how it copes with steep hills, and whether it stays within UK e-bike rules. Read on for our detailed, honest review of this long-range dual-battery machine.

What Is the ENGWE X26 Dual Battery Electric Bike?

Built for Distance and Tough Terrain

ENGWE designed the X26 for riders who need range above all else. Its standout feature is a dual-battery system with a total capacity of nearly 1,400 watt-hours. That’s almost double what most e-bikes offer. The bike also rolls on 4-inch-wide fat tyres that soak up bumps and provide grip on muddy paths.

Other key specs include full suspension, hydraulic disc brakes, and a bright LED headlight. It’s a heavy bike at around 38 kg, but that weight comes from the extra battery and sturdy build. You can order it from Biktron’s dedicated ENGWE X26 page where we stock this model with fast UK delivery.

First Impressions and Assembly

The X26 arrives mostly assembled. You just need to fit the handlebars, front wheel, and pedals. The instruction manual is clear, and the included tools make the job simple. After about 30 minutes, you’re ready to charge the batteries and ride.

On first glance, the bike looks massive but well-built. The fat tyres and double-battery frame give it a purposeful, go-anywhere stance. It feels solid and premium, though you’ll notice the weight when lifting it up steps.

Battery and Range: How Far Can You Really Go?

Dual-Battery Specs and Real-World Testing

The X26 uses two removable 48V lithium batteries hidden inside the frame. Together they offer 1,392 Wh of energy. On paper, that means up to 90 miles of assisted riding in the lowest power mode. In our tests, with a mix of hills and throttle use, we got a realistic 55 – 70 miles per full charge.

Factors like rider weight, headwinds, and tyre pressure will affect your range. We found that sticking to pedal-assist level 2 out of 5 and using the throttle sparingly gave the best balance of speed and distance.

Charging Time and Tips

You need to charge each battery separately with the supplied charger. A full charge from empty takes 6–7 hours per battery. That’s a bit of a faff, but you can also charge just one battery while riding on the other. We recommend charging overnight before a long ride, and always storing the batteries at room temperature.

If you’re looking for a lighter dual-battery option, the ENGWE L20 3.0 Pro Folding Electric Bike also boasts twin batteries but in a more compact, foldable design. It’s worth comparing if you need to carry your bike indoors.

Motor and Performance: Power for Steep Hills

Motor Type and Torque

Sitting in the rear hub is a 250-watt continuous-rated motor that peaks at 1,000 watts. This gives you strong acceleration and the ability to climb slopes without struggling. On a 15% gradient, we could maintain 8–10 mph in pedal-assist mode 5. Even with the throttle alone, it pulled us up gently.

The motor is noticeably quiet, even under load. Its 80 Nm of torque feels instant, making roundabouts and junctions less daunting. However, you must remember that UK law limits assisted speed to 15.5 mph – more on that later.

Assisted Speed and Riding Modes

You have five levels of pedal assist plus a thumb throttle. The motor cuts off smoothly at 15.5 mph in compliance with the UK EAPC regulations. After that, you’re pedalling unassisted, and with the bike’s weight, you’ll feel every extra kilo.

We liked the throttle for pulling away from traffic lights, but on long stretches it drains the battery quickly. For daily commuting, using assist level 2 or 3 and pedalling lightly is the sweet spot. You can discover more about UK e-bike power rules in our guide to cyclist safety from RoSPA.

Ride Comfort and Handling on All Terrains

Suspension and Fat Tyres

The X26 features a front suspension fork with 80 mm of travel plus a rear spring shock. Combined with the 4-inch CST tyres, it flattens out potholes, kerbs, and gravel tracks. At the recommended 20 PSI, the tyres act as an extra layer of cushioning.

You can tackle light woodland trails and bridlepaths confidently. The bike never felt twitchy or unstable, even over exposed roots. For a commuter who faces cobbled streets or canal towpaths, this is a huge benefit.

On-Road Manners

Although it’s an all-terrain machine, the X26 rolls nicely on tarmac once you’re moving. The upright riding position gives a good view over traffic. The only downside is the sheer weight when you need to pedal without assist; you’ll likely rely on the motor most of the time.

The gearing feels sensible, with a 7-speed Shimano derailleur. Shifting is crisp, though you’ll rarely use the top gears unless going downhill. We’d recommend the X26 as a comfortable mountain bike alternative for leisure paths and unsurfaced roads.

Design, Build Quality, and Practical Features

Frame and Durability

The 6061 aluminium frame is burly but well-finished. Welds are neat, and the integrated battery design keeps things tidy. A central kickstand supports the bike’s weight, though a double stand would be even better. The bike is not foldable; you’ll need a large storage space or a sturdy bike rack.

Available in black or grey, the X26 looks understated but purposeful. Mudguards are fitted as standard, which is a welcome touch for British weather. The standard rear rack can carry up to 25 kg, handy for panniers.

Display and Controls

The colour LCD display is bright and easy to read in sunlight. It shows speed, battery level (combined), assist mode, and trip distance. You can also switch between mph and km/h. The control pad is within thumb reach and feels durable.

One small gripe: there’s no USB charging port on the display, which could be useful for smartphones. Still, the inclusion of hydraulic brakes and a bright headlight shows attention to detail.

Is the ENGWE X26 UK-Road Legal?

Meeting EAPC Rules

To ride an e-bike legally on UK roads as an electrically assisted pedal cycle (EAPC), the motor must be no more than 250 watts continuous, assist must cut off at 15.5 mph, and you must be at least 14 years old. The X26’s motor is rated 250W and it includes a speed limiter, so it fully complies.

However, the bike has a thumb throttle that works independently of pedalling. Under UK law, a full-speed throttle is only allowed on e-bikes type-approved before 2016 or on “twist and go” models with a maximum unassisted speed of 3.7 mph. Most riders use the throttle sensibly on private land, but on public roads you must ensure the throttle only assists while you pedal, via the bike’s legal mode. For the official word, see the Electrically Assisted Pedal Cycles regulations 2015.

Riding Safely within the Law

We recommend sticking to pedal-assist mode and using the throttle only for starting off, combined with pedalling. Always wear a helmet and fit front and rear lights – the X26 includes a powerful front light but you’ll need a rear light for full compliance.

Because of its speed and weight, this bike demands a mature rider. If you’re new to e-bikes, our guide to picking a trusted brand covers more beginner-friendly options.

Who Should Buy the ENGWE X26?

Ideal Riders

This bike suits a few distinct groups. First, anyone with a long commute (over 15 miles each way) who wants to arrive sweat-free and not worry about charging at work. Second, countryside dwellers who ride on unsealed tracks and need the extra grip. Third, leisure riders who enjoy day-long adventures without battery anxiety.

If you often carry shopping or touring gear, the rear rack and huge range make it a practical cargo workhorse. Compare it with the ENGWE EP-2 Boost All-Terrain Folding Electric Bike if you need a folding alternative with similar off-road ability but a single battery.

Who Might Look Elsewhere

The X26’s weight and bulk rule it out for anyone who needs to lift it onto public transport, up stairs, or into a small car boot. If your journeys are short and you have limited storage, a lighter city e-bike would be more practical. Also, the high price point (around £1,600–£1,800) means it’s an investment.

Beginners might find the power intimidating. Start in a low assist level and practise in a safe area. For a gentler introduction, read our AAIRSK GT900 review which looks at a budget-friendly e-bike.

Final Verdict: Is the ENGWE X26 Worth It?

After 200 miles of testing, the ENGWE X26 impresses as a long-range tank of an e-bike. Its dual-battery setup genuinely banishes range anxiety for all but the most epic rides. Comfort is exceptional thanks to fat tyres and full suspension, and the powerful motor flattens hills.

Drawbacks are the weight and the need to charge two batteries, but if you need supreme distance and all-terrain capability, the trade-off is worth it. For the price, you get an e-bike that can replace a car for many daily journeys.
