The manufacturer's figures, not ours.
This one carries 1,040 Wh of battery. A full charge costs about £0.29. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

Based on £0.245 per kWh, £0.45 per mile to run a small car, and 2,200 miles a year. Charging is costed at the socket, not at the battery.
Nine gears, LG cells and levers that cut the motor
The Cyrusher Trax runs a Bafang motor with 80 Nm on a 52 volt LG battery, with Shimano nine speed and an IP65 rated frame, at £2,289 from £2,899.
Road legal at 250W: no licence, no tax, no insurance, nothing to register.
Brake levers with a motor cutoff switch
Logan anti-slip levers with a cutoff built in: the motor stops the instant you touch either one.
It is the sort of thing that never appears in a comparison and matters the one time you need it. On a full suspension fat bike on a descent, you want the motor to stop pulling before the brakes have to argue with it.
Nine gears, not seven
A Shimano nine speed, where almost everything in this catalogue has seven.
The motor stops assisting at 15.5 mph, so above that it is you and the gearing. Nine closely spaced ratios keeps the bike pleasant to pedal above the assist limit rather than feeling geared out.
An IP65 frame, which is a rating and not a claim
Cyrusher rate the frame IP65: dust tight and protected against water jets from any direction.
Most manufacturers say the bike is water resistant and leave it there. A number is a maker standing behind something and telling you where the limit is.
Air suspension at the back, lockout at the front
An air shock rated 165 by 750 lbs, tuned with a pump rather than accepting a factory spring, and a fork with both lockout and adjustment.
Lock the fork out for a road ride and open it for a track. That is two bikes rather than a compromise between them.
Twenty amp hours of LG cells
A 52 volt twenty amp hour LG pack rated for 800 charges, with a CE and UL certified charger and a five to seven hour fill.
Cyrusher quote 50 to 56 miles. Fifty two volts moves the same power at lower current, which means less heat and less sag when the motor is working hard.
The panel below turns the capacity into energy per mile and gives you the bands.
What is in the box
More than usual, and it is worth knowing before you order anything separately.
- An air pump, which you need for the shock and will otherwise buy
- A full assembly toolset and a guide
- The charger and the battery key
- A two year warranty
Kenda puncture resistant fat tyres and a 250 lumen light
Kenda four inch fat tyres on twelve gauge stainless steel spokes, with a 250 lumen LED headlight.
Two hundred and fifty lumens is a light to ride by on an unlit lane rather than a light to be seen by, which is what most bikes at any price actually fit.
Before the first ride
It arrives largely assembled with the tools to finish it.
- Fit the front wheel, handlebar and pedals
- Set the rear air shock with the supplied pump before anything else
- Bed the Logan brakes in at walking pace and check both cutoff switches
- Set tyre pressure: soft for grip, firmer for range on tarmac
- Charge to full before the first long ride
Two rows the table leaves blank
There is no range figure and no weight in our specification table for this model, because neither came through in a form we store, and we do not fill a blank with a guess.
Cyrusher state 50 to 56 miles elsewhere on their page, and we are telling you here where that came from rather than placing it in the table as though it arrived with the rest. A full suspension fat bike with a twenty amp hour battery will not be light.
Who it is for
Cyrusher size it for riders between 165 cm and 200 cm, which is 5ft 4in to 6ft 6in, and it carries 330 pounds.
It is the second most expensive bike in this part of our range, and what the money buys is the parts list: LG cells, a Bafang motor, nine Shimano gears, an air shock, a rated frame and levers that cut the motor. Buy it if each of those being real rather than nominal is what you are shopping for.

- 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.
