This Model Is Fully Compliant With UK Road Regulations
This bike is built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning it can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h).
See UK LegislationThis one carries 624 Wh of battery. The maker quotes 34 mi; in mixed riding with some hills, expect nearer 26 mi. A full charge costs about £0.17. Across a year that is roughly £979.00 less than making the same journeys by car, so the bike pays for itself in about 9 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

Twenty-seven and a half inch wheels at a town-bike price
The Varun M27-1 runs larger wheels than almost anything else near its money, on an aluminium frame with dual disc brakes.
Road legal at 250W: no licence, no tax, no insurance, nothing to register.
Bigger wheels, fewer surprises
A twenty-seven and a half inch wheel meets a rut at a shallower angle than a twenty-six, and carries its speed over rough ground rather than losing it into every hole.
On a bridleway or a badly patched road that is felt on every metre, and it is the main reason to choose this over a smaller-wheeled bike at the same price.
Fifty-five newton metres, which is generous here
Good torque for a road-legal motor. It is what you feel setting off at a junction or starting a climb, rather than what you read on a spec sheet.
Assistance stops at the legal limit; past that the gearing is yours.
Aluminium, and it will not rust
An aluminium alloy frame at a price where steel is the norm. Lighter, and it survives being left outside or on a car rack through a wet winter without corroding.
It is the quiet upgrade on this bike.
Dual disc brakes
Discs front and rear, which keep their stopping power when the wheels are wet where rim brakes do not.
Simple to adjust and cheap to maintain: a set of pads costs a few pounds at any shop in the country.
Four to six hours to fill
An evening from empty. Plug it in when you get home and it is ready by morning.
The panel below works out what a charge costs at the socket. On a bike used for short trips, it is the number that makes the case.
What to do before the first ride
It arrives largely assembled.
- Fit the front wheel, handlebar and pedals
- Set the saddle so your leg is nearly straight at the bottom of the stroke
- Check both brakes and the tyre pressure
- Charge to full once before the first long ride
Two figures the manufacturer did not give
Varun did not state a weight or a maximum load for this model, so we do not print either. The table below leaves those rows out rather than filling them with an estimate.
Both matter: one decides whether you can lift it onto a rack, the other whether the frame suits you. Ask us before you order and we will weigh one and check.
A short range for the battery it carries
Thirty-four miles is below the middle of our catalogue, and that is at the lowest assist level on flat ground. Large wheels are efficient, but a thirteen amp-hour pack is only so big.
The bands in the table below are the realistic version. If your round trip is long or hilly, buy a bigger battery rather than hoping: we have several, and we would rather point you at one than have this come back.

- 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.
