Private Land Use Only.
Not for public roads, pavements or cycle paths. Its motor and assisted top speed are above the UK EAPC limits of 250W and 15.5 mph, which makes it a motor vehicle in law. It would need registration, insurance and a licence. Ride it on private land.

The manufacturer's figures, not ours.
This one carries 768 Wh of battery. The maker quotes 50 mi; in mixed riding with some hills, expect nearer 38 mi. A full charge costs about £0.21. Across a year that is roughly £981.00 less than making the same journeys by car, so the bike pays for itself in about 12 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

Seven hundred and fifty watts, for private ground
The VARUN 26x4.0 is a high-power fat bike for land you own or have the owner's permission to use. Its 750W motor puts it beyond what UK road law allows, so we sell it for private use only: not a road, not a pavement, not a cycle path.
We put that first because it is the fact that decides the purchase. If you have nowhere private to ride, buy one of our 250W bikes instead.

Rated for gradients most bikes stall on
Varun quote this frame for climbs between seventeen and thirty-eight percent. Thirty-eight percent is a bank you would think twice about walking up.
Eighty newton metres is what gets you there: not top speed, but the shove that keeps the wheel turning when a smaller motor would spin and stop.

Big wheels and big tyres, together
Most fat bikes use twenty-inch wheels. This pairs four-inch tyres with twenty-six inch wheels, so it rolls over obstacles instead of climbing them and holds speed across rough ground rather than bleeding it away.
On a field or a forestry track that combination is worth more than any number on the spec sheet.

The brakes put charge back in
Braking is regenerative: some of what you scrub off on a descent goes back into the battery rather than into heat. Varun put the figure at around five percent.
It will not transform the range. What it does is slow the bike with the motor as well as the pads, which on a long descent means the discs are doing less work.

Sealed to IP65
Dust and driven rain are not a concern on a machine meant for fields and tracks, and the electronics are rated accordingly.
That rating is the difference between a bike that shrugs off a wet winter and one that develops an intermittent fault in February.

Two years of warranty, the longest we list
Varun back this with twenty-four months, which is longer than almost anything else in our catalogue.
On a high-power machine that will be used hard, that is not a detail. It is the manufacturer saying what it expects the bike to survive.


Aluminium, and rated for a heavy rider
The frame is aluminium rather than steel, which keeps some weight out of a bike that already carries a large battery and two fat tyres.
It is rated to a hundred and fifty kilos of rider and load, and suits riders from roughly five foot three to six foot five.

A fast charge, for once
Four to six hours from empty on a pack this size is quick. Most bikes with a battery this large take longer.
The panel below turns the capacity into energy and into what a charge costs at the socket.

What to do before the first ride
It arrives largely assembled.
- Fit the front wheel, handlebar and pedals
- Check both disc brakes carefully: this bike is quicker than it looks
- Set tyre pressure low for loose ground, higher for hard-packed
- Confirm you have somewhere private and lawful to ride it
- Charge to full once before the first session

Heavy, and heavier when it is flat
This is among the heaviest bikes we sell, and the power makes it feel heavier still once the battery is empty. Pedalling thirty-five kilos home unassisted is not an afternoon anyone enjoys.
Plan your sessions around the charge rather than finding the bottom of it.

The limit, stated plainly
You cannot legally ride this on a public road, pavement or cycle path in the UK. A motor over 250W is not an electrically assisted pedal cycle, and no amount of care changes that.
If you have the ground for it, this is one of the most capable machines we stock. If you do not, it is the wrong purchase and we would rather sell you a 250W bike that you can actually use.

10 of 11 specifications differ. View DYU A1F Electric Folding Bike
- What is the top speed of the VARUN S26-1 Electric Bike?
- The bike provides pedal assistance up to 15.5 mph, making it compliant with UK and EU e-bike regulations. In certain markets, the speed can be unlocked for private property use where legally permitted.
- Does the VARUN S26-1 have full suspension?
- Yes. The bike features front and rear suspension, providing improved comfort, better traction, and enhanced control on rough roads and off-road trails.
- Is the VARUN S26-1 suitable for off-road riding?
- Yes. Its 26 × 4.0-inch fat tires, 85 Nm motor, full suspension, and Shimano 7-speed drivetrain make it ideal for gravel paths, mountain trails, sand, snow, and mixed-terrain riding.
- Are the electric bikes brand new?
- Yes. All electric bikes sold by BikTron are brand new, factory-sealed, and sourced directly from authorised manufacturers and official distributors.
- How do I choose the right electric bike for me?
- Pick a bike based on how you plan to ride. City bikes are great for commuting, folding bikes work well if you need compact storage, mountain bikes handle hills and mixed terrain, and cargo bikes are ideal for carrying shopping or loads. If you are not sure, our Bike Quiz can help.
- Are the batteries original and certified?
- Yes. Every electric bike battery is brand new and original from the manufacturer, with full safety certification and performance testing.
- Are the bikes tested before shipping?
- Yes. Each e-bike goes through a quality check before dispatch, covering electronics, brakes, motor response, and battery performance.
- Do electric bikes come with a warranty?
- Yes. All electric bikes from BikTron include a manufacturer warranty. Duration depends on the brand and model. Most bikes include a 12-month warranty as standard.
- How long does delivery take?
- Standard UK delivery usually takes 2 to 7 business days. Remote areas may take a little longer. You will receive a tracking link by email once your order is dispatched.
- Which payment methods do you accept?
- We accept Visa, Mastercard, PayPal, Apple Pay, Google Pay, and Klarna buy-now-pay-later. All payments are processed securely.
- Can I return my electric bike?
- Yes. You can ride the bike and still return it. Tell us within 30 days of delivery and we book the courier and collect it from your door. Contact us first and we will guide you through the process.
- Do the bikes need assembly?
- Most electric bikes arrive 85 to 90 per cent pre-assembled. You will usually need to attach the handlebars, pedals, and adjust the seat. A basic tool set is often included.
- Are BikTron electric bikes legal to ride in the UK?
- Yes. All bikes sold by BikTron that meet UK EAPC rules (250W motor, max 15.5 mph assisted speed, pedal-assisted only) are fully road-legal. You do not need a licence, tax, or insurance to ride them on public roads. Riders must be at least 14 years old.
- What about the electric scooters?
- Those are different, and the law treats them differently. A privately owned e-scooter cannot legally be ridden on a public road, pavement or cycle lane in the UK, whoever sold it. We sell ours for private land use only, with the landowner's permission, and every scooter product page says so. If you want something you can ride to work, choose an electric bike.
