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 360 Wh of battery. The maker quotes 37 mi; in mixed riding with some hills, expect nearer 28 mi. A full charge costs about £0.10. Across a year that is roughly £984.00 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.

Magnesium alloy, and fifty-one pounds
The DYU T1 uses a magnesium alloy frame, which is why it weighs less than four fifths of our catalogue while carrying a battery and folding in half.
Road legal at 250W: no licence, no tax, no insurance, nothing to register.

Weight is the specification that decides whether it gets folded
A folding bike too heavy to lift is a bike that stays unfolded in a hallway. Fifty-one pounds is light enough to put in a boot, carry up a step, or get onto a train without planning the manoeuvre first.
Magnesium is how the frame gets there: lighter than steel, and almost nothing else at this price uses it.

Twenty-inch wheels, the sensible middle
Larger than the fourteen and sixteen-inch wheels on the smallest folders, so it rides steadily rather than nervously, and small enough to keep the folded package compact.
For most riders that is the better end of the trade, and it is why twenty inches is the size most folding bikes settle on.


Magnesium does not rust
It also does not corrode the way steel does when a bike lives in a damp shed, gets rained on at a station, or spends the winter under a cover on a balcony.
On a bike designed to be left places, that matters more than it sounds.

Thirty-five newton metres, on a light bike
Modest torque, and on a bike this light it does not need to be more. There is far less to move than on a seventy-pound folder, so the same motor goes further and works less hard.
Assistance stops at the legal limit, where the gearing and your legs take over.


Five hours on charge
An evening from empty. Plug it in when you get home and it is ready by morning.
The panel below turns the capacity into energy and into what a charge costs at the socket. On a battery this small the answer is barely measurable.

What to do before the first ride
It arrives largely assembled.
- Unfold and lock the frame hinge and the stem
- Fit the pedals and set the saddle height
- Check the brakes carefully before you ride: see the note below
- Check tyre pressure
- Charge to full once before commuting on it


The braking system is not stated
DYU did not tell us what brakes are fitted, so we do not print a guess. The table below leaves that row out rather than filling it.
It is worth asking us before you order, and it should be: brakes are not a detail on any bike, folding or not.

A small battery and a low weight limit
Ten amp-hours is among the smaller packs we sell, and the thirty-seven mile claim is measured at the lowest assist level on flat ground. The bands in the table below are the realistic version, and winter takes more off them.
The rated payload is also lower than almost everything else on our shelf: check it in the table against your own weight plus what you carry. Buy this for the low weight and the magnesium frame, which are real and unusual at the price. Do not buy it for a long hilly commute.

- What is the maximum range of the DYU T1 Folding E-Bike?
- The DYU T1 offers up to 34 miles of pedal-assisted riding on a full charge under ideal conditions. Actual range depends on terrain, rider weight, weather, and riding style.
- Does the DYU T1 have a torque sensor?
- Yes. It features a 35 Nm torque sensor that delivers smoother, more natural pedal assistance by responding to your pedalling force.
- Is the DYU T1 foldable?
- Yes. The magnesium alloy frame folds quickly, making it easy to store and transport in cars, apartments, offices, or on public transport.
- Is the DYU T1 suitable for daily commuting?
- Yes. Its lightweight folding design, removable battery, Shimano 7-speed gears, torque sensor, and 34 miles assisted range make it an excellent choice for everyday city commuting.
- 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.

- 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.
