The Varun M26-3 PRO Folding Electric Bike is one of the most affordable legal folding e-bikes in the UK. It is priced at £549, down from an RRP of £649, and it sits in the middle of the Varun range at Biktron.
This review does not pretend to be a hands-on ride. We have not ridden this exact bike. Instead, we judge the published specification, the price you pay and how well it fits UK e-bike rules in 2026.
Who is the Varun M26-3 PRO for?
This is a folding commuter bike built for short or mixed journeys. You ride a few miles to the station, fold it and carry it onto a train, then ride the last mile to work.
It suits a rider who wants a car-free option without storing a full-size bike in a hallway. The upright riding position and step-through style make it easy to use in normal clothes.
Commuters and car-boot riders
If your commute is under eight miles each way and mostly flat or gently rolling, this bike fits well. You charge it at your desk or in a hallway and avoid paying for parking.
The fold also helps people who drive part way. A folded e-bike fits in many car boots, so you can park outside the city and ride in.
First-time e-bike buyers
The M26-3 PRO keeps the controls simple. There is a legal 250W motor, a small display and a throttle-free pedal assist set-up that matches UK law.
This matters if you want an e-bike that is legally a bicycle, not a moped. There is no licence, tax or MOT to worry about.
What you actually get for £549
At £549, this is a budget e-bike. You are not buying a premium Bosch motor or a 100-mile battery. You are buying a capable town bike with a folding frame.
The Varun M26-3 PRO Folding Electric Bike uses a 20-inch wheel size, which keeps the folded package small. The frame is aluminium and the battery is usually mounted behind the seat tube.
- 250W rear hub motor with pedal assist up to 15.5 mph
- Folding aluminium frame with 20-inch wheels
- Mechanical disc brakes and a basic gear set
- Removable battery behind the seat tube
- LED display showing assist level and battery level
Frame, folding and build
The folding mechanism sits in the middle of the frame. You release a clamp, fold the bike in half and drop the handlebar stem. It locks closed so you can carry it one-handed for short distances.
There is no suspension fork on this model, so the ride is firmer than a mountain bike. That is normal for a folding city bike, because suspension adds weight and cost.
Motor and controls
The rear hub motor is rated at 250W, the legal maximum for an electrically assisted pedal cycle in the UK. Assistance stops at 15.5 mph, as the law requires.
You choose assist levels from a handlebar display. Because it is pedal assist rather than throttle only, the bike helps you while you pedal. It does not do all the work for you.
UK e-bike law and where this fits
In the UK, an electric bike must meet the EAPC rules to be treated as a normal bicycle. The motor must be 250W or less, and the power must cut out at 15.5 mph.
You must be at least 14 years old to ride one on public roads. You do not need a licence, insurance or a helmet by law, although a helmet is strongly advised.
The government e-bike rules explain this in plain English. The Varun M26-3 PRO is designed around those limits.
EAPC rules in plain English
Your bike is an EAPC if it has pedals, shows the manufacturer's power rating and cuts assistance above 15.5 mph. The motor can still help you up a hill, but only while you pedal.
This matters for insurance and police stops. As long as the bike is not modified, you can ride it anywhere a normal bicycle is allowed.
- Motor must be 250W or less
- Assistance must stop at 15.5 mph
- Rider must be 14 or older
- No licence, tax or MOT needed
What the M26-3 PRO means for insurance and licence
Because this bike is EAPC compliant on paper, you do not need to register it with the DVLA. You also do not need an MOT or a moped licence.
You may still want cycle insurance for theft or damage. Cycling UK has useful guidance on what bike insurance covers. Sustrans also explains how e-bike power works.
Range, charging and battery care
Range claims on any e-bike are optimistic. They assume a light rider, smooth tarmac, warm weather and low assist. Real UK rides will be lower.
For a 20-inch folding e-bike at this price, expect somewhere around 20 to 35 miles on lower assist. That is enough for most short commutes and errands.
Cold weather reduces range, and so do hills. If your route is hilly, plan to charge more often or carry the charger with you.
Real-world UK range
You will get the best range in level two of three or five assist levels. Full power on a windy day might drop the range below 20 miles.
If you need more than 25 miles between charges, look at a bigger battery or a model with a higher capacity pack. The VARUN S20-2 PRO Folding Electric Bike is a step up in price and battery.
Charging habits that protect the battery
Charge the battery indoors at room temperature. Do not leave it plugged in for days, and avoid running it completely flat every ride.
Most battery packs take four to six hours to charge. A partial charge is fine, and it is better to keep the battery between 20 and 80 percent when possible.
- Keep the battery away from extreme heat and cold.
- Charge in a dry room and unplug when full.
- Avoid deep discharges every day.
- Use the charger supplied with the bike.
Ride quality and comfort without a test ride
We cannot tell you how this bike feels on your street. We can tell you what the geometry and parts suggest. Small wheels accelerate quickly but feel bumps more than 26-inch wheels.
The saddle is usually padded for comfort, and the handlebar is set high. That gives a fairly upright position, which many commuters prefer.
20-inch wheels and road feel
Small wheels make a bike nimble in traffic and easy to store. The downside is that potholes and kerbs transfer more shock to your hands and backside.
Wider tyres help a little, but there is no full suspension on this model. If your route has rough roads, consider a fatter tyre like the Varun S20-1 Electric Bike.
Brakes, gears and saddle
The M26-3 PRO uses mechanical disc brakes in most builds. They work well in the wet and are easy to adjust at home.
A basic gear set is enough for gentle hills. You will not win a climb against a road bike, but the motor fills in when you slow down.
Folding and storage in real life
The main reason to buy this bike is the fold. It is not the smallest folder available, but it folds enough for a flat or a train vestibule.
Measure your storage space before ordering. A folded 20-inch e-bike is still heavy, usually around 20 to 25 kg, so you will not want to carry it up five flights of stairs.
Size when folded and carrying
Folded dimensions vary, but expect a package roughly 80 cm by 60 cm by 40 cm. It will sit in a hallway or under a desk if space allows.
There is often a small magnet or latch to keep the frame closed. Check it is secure before lifting, because a loose fold can swing open.
Trains, offices and flats
Many train operators allow folding bikes at any time if they are covered or carried. Check the operator's rules before you travel.
In an office, it can charge under a desk. In a flat, it stands against a wall. The Folding Bikes category has other options if you need a smaller fold.
How it compares to other Biktron folders
The M26-3 PRO is the cheapest folding model in the current Varun range. It costs £549, while the VARUN S20-2 PRO costs £879 and the Varun S20-1 Electric Bike costs £702.
The extra money on the S20-2 PRO buys a chunkier battery and a more refined build. The S20-1 adds fat 20x4 tyres for better comfort on towpaths and light trails.
Price and feature trade-offs
For pure town commuting, the M26-3 PRO does the same legal speed as the more expensive models. The difference is range, weight and ride comfort.
If you rarely ride more than ten miles in a day, the cheaper model makes sense. If you want longer rides or extra cushioning, step up.
Which one fits your journey
Think about your route before choosing. A flat city route with good tarmac suits this bike. A route with gravel or rough paths leans towards a fat tyre model.
There is no single right answer, but the M26-3 PRO is the best value for a simple folding commute.
Who should not buy it
This is not a bike for everyone. If your route has long, steep climbs, a 250W hub motor may struggle, especially with a heavier rider.
It is also not a long-distance tourer. The battery and riding position are set up for town trips, not a 50-mile weekend ride.
Long or steep commutes
If you have a 12-mile each-way commute with big hills, you will drain the battery quickly. You may need to charge at work and at home.
A full-size e-bike with a larger battery may suit you better. Look at the Mountain Bikes category for more range and torque.
Riders over 100 kg or needing high speed
The motor still assists up to 15.5 mph, but heavier riders will see lower range and slower hill climbing. Check the product page for the official weight limit.
If you want a throttle that works without pedalling or assistance above 15.5 mph, UK law would class the bike as a moped. That is a different type of machine and needs registration.
Verdict: is the Varun M26-3 PRO worth £549?
For a legal, foldable, everyday e-bike, the price is hard to beat. You get a real 250W motor, a folding frame and enough range for most city journeys.
The downsides are clear. It is firm over rough roads, the battery is not huge, and it is not designed for steep climbs or long rides.
Value against the rest of the range
The M26-3 PRO costs £549. That is a fair price for a folding e-bike with these parts, but it is still budget-level. The S20-2 PRO adds a better battery and costs £879.
If your priority is the lowest price for a legal folder, this model wins. If you value range and smoother power, spend a little more.
Final recommendation
Buy the Varun M26-3 PRO if you want a simple, legal folding e-bike for short commutes and errands. It is not a premium product, but it does the job at £549.

Frequently asked questions
Is the Varun M26-3 PRO legal to ride without a licence in the UK?
Yes. It uses a 250W motor and stops assistance at 15.5 mph, so it meets the EAPC rules. As long as you do not modify it, you need no licence, tax or MOT. You must be 14 or older to ride on public roads.
How far will it go on one charge?
On lower assist levels, expect around 20 to 35 miles in real UK conditions. Hills, cold weather and heavier riders reduce that. Manufacturer range figures are usually higher than real-world numbers.
Can I take it on a train?
Many UK train operators allow folding bikes at any time if they are folded or covered. Check the specific operator before you travel, because rules vary by route.
Does the battery come off for charging?
Yes, the battery is removable on this model. You can take it indoors to charge while the bike stays folded in a hallway or office.
What is the weight limit?
Varun does not publish a single universal figure. Check the specification tab on the product page. Most bikes in this class handle around 100 to 120 kg of total rider and luggage weight.
