Product Description

The IMREN UK Road-Limited Fat Tyre Electric Bike is a step-through electric bicycle configured specifically around the principal power and assistance limits used for electrically assisted pedal cycles in Great Britain.

The supplied configuration uses a 250W continuous-rated electric motor, while motor assistance is programmed to cut off at 15.5 mph / 25 km/h.

These are the core motor-power and assistance-speed limits stated in current UK government EAPC guidance. The bicycle also has functional pedals capable of propelling the cycle. Final EAPC status additionally depends on the complete physical configuration and required vehicle markings.

Unlike unrestricted higher-output IMREN-style fat bikes that may appear elsewhere online, this exact SKU is sold as:

IMREN-FAT-250W-UK

and should remain listed with:

250W continuous rated output / 15.5 mph assistance cut-off.

Power is supplied by a 48V 16Ah removable lithium-ion battery, providing 768Wh of nominal energy capacity.

The current product listing estimates a range of approximately 35–50+ miles, depending on factors such as rider weight, terrain, assistance setting and riding conditions. This figure should be treated as an estimated operating range rather than a guaranteed distance.

Electric assistance is managed through an intelligent five-level pedal-assist system. The current exact UK road configuration lists the throttle as disabled, helping keep the supplied setup focused on pedal-assisted operation.

Mechanical gearing comes from a Shimano 7-speed drivetrain. The current specification identifies a Shimano Altus 7-speed rear derailleur, Shimano Tourney shifter and Shimano 7-speed freewheel.

The bike uses large 26″ × 4″ all-terrain fat tyres, giving it a broad tyre contact patch compared with conventional narrow commuter tyres.

The front end incorporates an alloy suspension fork, while stopping performance is provided by hydraulic disc brakes.

An A6061 aluminium TIG-welded step-through frame provides an accessible mounting design, while the wide tyres, suspension fork and comfort saddle are intended to support everyday and leisure riding.

The current specification also includes a rear luggage rack and integrated lighting, adding practical utility for day-to-day cycling.

A C900E+ LCD display presents key ride and assistance information and incorporates a USB output.

The complete bicycle weighs approximately 72 lb, supports a published total payload of 350 lb, and is recommended for riders approximately 5’3″ to 6’4″ tall.

The above product-specific values are published on the exact IMREN/Pure Pedal listing.

Motor Configuration

250W Continuous Rated Motor

The exact UK configuration is limited to:

Continuous Rated Motor Output: 250W

This wording matters because UK EAPC rules refer specifically to maximum continuous rated power, not temporary peak power.

For this exact product page, do not replace 250W with specifications from unrestricted IMREN bikes.

Assistance Speed Configuration

15.5 mph / 25 km/h

Electric motor assistance is configured to cut off at:

15.5 mph / 25 km/h

The bicycle can still be pedalled beyond that road-assist threshold; the published limitation applies to electric assistance.

UK government guidance states that an EAPC motor must not continue propelling the bicycle when it is travelling above 15.5 mph.

UK Road Configuration

The exact retailer/operator specification lists:

• 250W continuous-rated output
• 15.5 mph / 25 km/h electric-assist limit
• Functional pedals
• Pedal-assist system
• Throttle disabled in the UK road configuration

These specifications align with the core motor-power and speed requirements of Great Britain’s EAPC framework.

Important Legal Accuracy Note

Do not advertise the bicycle merely as “100% UK road legal in all circumstances” based only on motor wattage and speed.

Current government guidance also requires applicable EAPC markings, and vehicles capable of throttle-only propulsion can have additional approval requirements.

A safer ecommerce description is:

“Supplied in a UK road-limited 250W / 15.5 mph pedal-assist configuration designed around the principal Great Britain EAPC power and speed limits. Users should follow applicable local regulations.”

Throttle Configuration

Supplied UK Version

Throttle: Disabled

The current exact product specification states that the throttle is disabled for the UK road configuration.

This is an important difference from unrestricted versions.

Do not advertise:

• Full-speed throttle
• Throttle-only 15.5 mph operation
• Unlockable road mode
• Off-road high-speed mode

for this exact road-limited SKU unless separate approved documentation supports it.

Current Department for Transport guidance warns that cycles with an “off-road” mode allowing motor propulsion above 15.5 mph are not considered compliant EAPCs.

Battery Configuration

48V 16Ah / 768Wh

Battery Voltage: 48V
Battery Capacity: 16Ah
Nominal Energy: 768Wh
Configuration: Removable, frame integrated

The removable design allows the battery to be taken off the bike for suitable charging or storage.

Range Configuration

Approx. 35–50+ Miles

The current product listing estimates:

Approximately 35–50+ miles

depending on:

• Rider weight
• Terrain
• Pedal-assist level
• Weather
• Riding speed
• Battery condition
• Stop/start frequency
• Tyre pressure
• Route conditions

Recommended Ecommerce Wording

Use:

“Estimated range approximately 35–50+ miles depending on riding conditions.”

Do not state:

“Guaranteed 50-mile range.”

Charging Configuration

Charger: UK-Compatible Smart Charger
Published Charging Time: Approx. 6–9 Hours

Pedal Assist Configuration

The bike uses an:

Intelligent 5-Level Pedal Assist System

This allows electrical assistance to be varied while retaining functional pedal propulsion.

Display Configuration

C900E+ LCD Display

The exact listing specifies:

C900E+ LCD

with:

USB Output

The display provides the rider interface for assistance and ride information.

Drivetrain Configuration

Shimano 7-Speed

Number of Gears: 7
Rear Derailleur: Shimano Altus
Shifter: Shimano Tourney
Freewheel: Shimano 7-Speed

The mechanical gears operate separately from the five electric pedal-assist levels.

Frame Configuration

A6061 Aluminium

Material: A6061 Aluminium
Construction: TIG-Welded
Style: Step-Through

The step-through layout provides lower frame clearance when getting on or off the bike.

Suspension Configuration

Front Suspension Fork

The bike uses an:

Alloy Front Suspension Fork

The exact public listing does not give a reliable travel measurement, so suspension travel should not be invented.

Brake Configuration

Hydraulic Disc Brakes

The current product specification identifies:

Hydraulic Disc Brakes

for the bike.

The exact public specification does not publish rotor diameter or caliper model, so those values should remain unspecified unless separately verified.

Wheel & Tyre Configuration

26″ × 4″ Fat Tyres

Wheel/Tyre Size: 26″ × 4″

These wide tyres increase tyre volume and ground contact compared with conventional narrow commuter-bike tyres.

The exact tyre brand/model is not published on the current listing and should therefore not be assumed.

Comfort & Utility Configuration

Standard practical equipment includes:

• Step-through frame
• HQ comfort saddle
• Front suspension
• Fat tyres
• Rear luggage rack
• Integrated lighting
• LCD display
• USB output

Rider Fit & Capacity

Recommended Rider Height: 5’3″–6’4″

Published Total Payload: 350 lb

Bike Weight: Approx. 72 lb

The 350-lb value is the total payload capacity and should not automatically be described as cargo capacity in addition to rider weight.
