The manufacturer's figures, not ours.
This one carries 960 Wh of battery. The maker quotes 50 mi; in mixed riding with some hills, expect nearer 38 mi. A full charge costs about £0.27. Across a year that is roughly £978.00 less than making the same journeys by car, so the bike pays for itself in about 32 months. Everything here is worked out from this bike's own specification. Estimates, not promises: the assumptions are printed underneath.

A mid-drive motor, 160 Nm, and a step-through frame
The Cyrusher Quest runs a mid-drive motor making 160 Nm, carries 440 lbs and steps through, at £2,564, down from £4,399.
250W and 15.5 mph: it meets the EAPC rules, so there is no licence, no tax and no registration.
The motor is at the pedals, not in the wheel
Almost everything in this catalogue puts the motor in the rear hub. This one has it at the centre of the bike.
- The motor goes through your gears, so it multiplies as you do
- On a hill it pulls far harder for the same rated power
- The weight is low and central, which matters on a 104 lb bike
- And the rear wheel comes off like any ordinary bike's
160 newton metres from a legal motor
That is the highest torque figure in this catalogue, and a mid-drive is how it is reached.
Torque is what climbs a steep hill without a run-up and what moves a loaded bike away from a standstill. Rated power says nothing about either, and on a machine this heavy it is the number that decides how it feels.
A step-through frame on a 104 lb bike
You get on without swinging a leg over a top tube, which on a bike this heavy is not a small thing.
It is the combination that makes the Quest unusual: the frame of a comfortable town bike with the torque and payload of a cargo machine.
440 lbs of payload
Two hundred kilogrammes, more than 97% of what we sell: rider, kit and cargo together.
Subtract your own weight before you order, and remember the bike is 104 lbs on its own. Twenty by four inch fat tyres keep the centre of gravity low under a load.
Hydraulic brakes, and at this weight they are necessary
Hydraulic rather than cable, on a 6061 aluminium frame with a 48V 20Ah battery.
One finger is enough, they do not fade on a long descent, and they keep their bite in the wet. Fifty miles of claimed range and five hours to charge.
What we know about this bike, and what we do not
This model reached our catalogue before we started archiving our suppliers' own spec sheets, so there is no original table for us to check ours against.
What the table below shows comes from our own record and nothing has been added to it on a guess. If a specific measurement decides your purchase, write to us before you order and we will measure it rather than guess.
Before the first ride, and who it is for
It arrives nearly built and weighs 104 lbs. Unpacking is a two-person job, without exception.
- Fit the front wheel and the handlebars with two people
- Bed the hydraulic brakes in at walking pace before you ride it loaded
- Learn the bike empty before you put weight on it
- Ease off the pedal as you change gear, as you would on any mid-drive
- Allow five hours for the first charge
Buy it for the mid-drive and the step-through together, with £1,835 off. It carries like a cargo bike and you get on it like a town bike, and very little does both.

- How far can the Cyrusher Quest travel on one charge?
- The Quest offers a maximum riding range of 50–80 miles (50-81 miles) depending on terrain, rider weight, weather, and pedal assist level.
- What motor does the Cyrusher Quest use?
- It is equipped with a Bafang M620 mid-drive motor that delivers 160 Nm of torque, providing excellent climbing performance and efficient power delivery.
- Does the Cyrusher Quest have full suspension?
- Yes. The bike features a DNM 160 mm front air fork, DNM rear air shock, and suspension seatpost for maximum comfort on rough terrain.
- Is the Cyrusher Quest suitable for off-road riding?
- Yes. With its mid-drive motor, full suspension, 20 × 4-inch fat tyres, hydraulic disc brakes, and Shimano 9-speed drivetrain, the Quest is designed for mountain trails, gravel roads, snow, sand, and challenging off-road adventures.
- 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.
