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 468 Wh of battery. The maker quotes 37 mi; in mixed riding with some hills, expect nearer 28 mi. A full charge costs about £0.13. Across a year that is roughly £982.00 less than making the same journeys by car, so the bike pays for itself in about 7 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

A 16-inch step-through with an IP65 rating
The isinwheel U2 has a 45 cm step-through, an IP65 rating and a rear carrier fitted, at £559.
isinwheel states a 500W motor and 20 mph. We sell it for private land only. Read the panel above before you order.

Where you may ride it, and where you may not
In the UK an electric bicycle is capped at 250W and must cut its assistance at 15.5 mph. This is twice the power and above the speed.
It is sold for your own land, or land whose owner has given you permission. On a public road it would be a moped: registration, insurance, tax and a licence.


IP65, and that is a step above
Dust-tight and protected against water jets from any direction, where most machines at this price claim IP54 or nothing at all.
- Driving rain, not just splashing
- It is a measured rating, not a promise
- On a bike that lives outdoors it is what decides how long it lasts
- And the headlight is rated at 111 lumens, a figure rather than a claim


Forty-five centimetres to step over
That is low, and on a 59 lb bike it is what makes the difference.
You get on without lifting your foot higher than a stair, and off onto one foot at a standstill. The saddle adjusts from 87 to 101 cm and the handlebars from 103 to 113.


isinwheel publishes both ranges
Thirty-seven to forty-seven miles on the throttle alone, forty-seven to sixty-five with pedal assist, from a 36V 13Ah removable pack of 374 watt hours.
Our table carries 37 miles, the bottom of that band. Their own FAQ adds that real range varies with terrain, rider weight and assist level, which is more honesty than most sheets offer.


The brakes are mechanical, and you should know that
Cable rather than hydraulic, on a machine stated at 20 mph.
They stop well and want the cable tension checking now and then, but on a bike ridden above 15 mph we would prefer hydraulic. It is the line that gives us most pause on this sheet, and we would rather write it than leave you to find out.

A rear carrier, included
isinwheel fits its own rear rack rather than leaving it as an accessory, at 72 cm off the ground.
Sixteen by 1.75 inch pneumatic tyres, a 6061 aluminium fork, an adjustable seat post and an 8.4 × 5 cm LCD display. isinwheel sizes it for riders of 5 ft 3 in to 6 ft 3 in.

Before the first ride, and who it is for
It arrives in a box 144 × 24.5 × 65.5 cm for a 59.5 lb bike. Payload is 265 lbs, lower than 96% of our catalogue, so check it against your own weight.
- Fit the front wheel, the handlebars and the pedals
- Bed both mechanical brakes in at walking pace and set the cable tension
- Check that tension again after the first ride
- Inflate firm: a 1.75-inch tyre takes high pressure
- Charge it fully before the first long ride
Buy it for the weather rating and the low step-through, on land of your own. The mechanical brakes are the compromise that pays for the price.

- 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?

- 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.

- 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.

- 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.
