This one carries 374 Wh of battery. The maker quotes 35 mi; in mixed riding with some hills, expect nearer 26 mi. A full charge costs about £0.10. Across a year that is roughly £983.00 less than making the same journeys by car, so the bike pays for itself in about 8 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

Eighty newton metres for five hundred and ninety nine pounds, for private land

The VARUN C20-1 puts 80 Nm of torque and a 500W motor on a twenty inch frame, at £599 from £699.

At that power it sits outside the UK road rules, so we sell it for private use on private land. Please read the panel above before you order.

Where you can and cannot ride it

The rules cap an electrically assisted pedal cycle at 250W continuous. This motor is rated at 500W, so it falls outside that and cannot be ridden on a road or a cycle path without registration, tax, insurance and a licence.

It is sold for use on your own property, or on land where the owner has given you permission. If you need something for a commute, look at the 250W bikes we list and we will point you at the right one.

Eighty newton metres, and a gradient figure to go with it

Torque is what pulls you away from a standstill and up a slope. Eighty newton metres is the top of our range under six hundred pounds, and unusually VARUN also publish what it means: a gradient capability of seventeen to thirty eight per cent.

Thirty eight per cent is a one in two point six slope. Most manufacturers will not put a number on this at all, and a number is worth more than an adjective.

Regenerative braking, which almost nothing here has

The brakes recover energy back into the battery, and VARUN claim about five per cent restored.

Five per cent is not going to change your day. What it does change is brake wear on a long descent, because the motor is taking some of the work the pads would otherwise do.

Varun C20-1 Electric City Bike view 5

The battery is small, and that is the trade

Seven point eight amp hours at 48 volts. Only two per cent of our catalogue carries less.

VARUN quote 55 to 70 km on the motor alone and 80 to 128 km with pedalling, both measured with a 65 kg rider, which is a heavier caveat than it sounds. A larger rider will see less.

The panel below turns the capacity into energy per mile and gives the honest bands. Treat this as a bike for short, powerful journeys rather than long ones.

IP65, a horn and a light

Rated IP65, which is dust tight and rated against water jets from any direction, with a CE certificate and a twenty four month warranty.

  • A mechanical horn rather than a bell
  • A headlight fitted from the factory
  • Dual disc brakes front and rear
  • A suspension fork on a twenty inch wheel

Most bikes at six hundred pounds say nothing about water ingress at all.

Varun C20-1 Electric City Bike view 7

Read the two weight limits before you order

The rider weight limit is a hundred kilograms and the total payload is 220 pounds, which is lower than ninety nine per cent of our catalogue.

That is the real constraint on this bike, not the battery. If you are over sixteen stone, or you are near it and you carry anything, this is not the right frame and we would rather say so now than after it arrives.

Who it fits

VARUN size it for riders between 150 cm and 185 cm, which is 4ft 11in to 6ft 1in. Twenty inch wheels on a 1.96 inch tyre, so a narrow tyre rather than a fat one.

The frame is aluminium and the whole bike is sixty four pounds.

Varun C20-1 Electric City Bike view 9

Before the first ride

Four to six hours on the fast charger, and it arrives largely built.

  • Fit the front wheel, handlebar and pedals
  • Set the saddle to hip height
  • Check tyre pressure, which matters on a narrow tyre
  • Bed the discs in before you use the power in earnest
  • Charge to full before the first ride
Varun C20-1 Electric City Bike view 10

Who should not buy it

Anyone who needs to ride on a public road, anyone over a hundred kilograms, and anyone who wants long distance. Those are three real limits and none of them is negotiable.

Buy it if you have land, you are inside the weight and height range, and you want the strongest torque figure we sell for under six hundred pounds. On a steep private track, nothing else in this price bracket will pull like it.

10 of 11 specifications differ. View DYU A1F Electric Folding Bike

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.
