Overview

Ideal for commuters, recreational riders and rail-trail explorers who want a comfortable, ready-equipped e-bike with useful range and straightforward handling.

The dyson Hard Tail Evo RTC 2026 is built around a comfortable, practical electric hardtail format. The 250 W high-torque hub motor delivers smooth pedal assistance, while the enclosed fast-response cadence sensor helps the motor respond promptly as you start pedalling. With six selectable assistance levels, you can keep the ride light on easy paths or add more support for hills and headwinds.

The 630 Wh removable battery gives you a typical range of 50–80 km, with real-world distance varying according to assistance level, terrain, rider weight and conditions. The frame-integrated battery is lockable and protected, and the colour display keeps key information easy to read while providing a handy USB-C charging output.

This is the bike we recommend when you want commuting convenience without building a bike up from scratch. The integrated front and rear lights, colour-matched aluminium mudguards and MIK HD rack are ready for everyday use, while the swept handlebar, adjustable stem and comfort gel seat create a relaxed riding position. On the road, the assistance feels immediate and useful for getting away from intersections and smoothing out climbs; beyond the 25 km/h assistance limit, you can continue pedalling normally. The Suntour fork, wide 27.5 × 2.35 tyres and hydraulic brakes add control and comfort on uneven streets, shared paths and light rail-trail riding.

Large integrated battery

The lockable, removable 630 Wh battery provides a typical 50–80 km range and can be taken off the bike for charging.

Smooth hub-motor assistance

The 250 W high-torque hub motor and fast-response cadence sensor make starts, hills and headwinds easier without adding complexity to the drivetrain.

Ready for commuting

Integrated battery-powered front and rear LED lights, aluminium mudguards and a heavy-duty centre kickstand come fitted from the start.

MIK HD rear rack

The integrated rack makes it easier to carry panniers, rack bags and compatible child seats for practical everyday trips.

Comfortable upright setup

Swept 680 mm handlebars, an adjustable alloy stem and a comfort gel seat give you a relaxed, confidence-inspiring riding position.

Controlled stopping

Tektro hydraulic disc brakes with large 180 mm rotors provide strong, progressive braking, with automatic motor cut-off when you pull the levers.

Light trail capability

The 100 mm Suntour XCM 30 fork, lock-out function and wide 27.5 × 2.35 tyres add stability and comfort on uneven paths and rail trails.

Useful ride information

The water-resistant colour display shows battery level, speed and trip information, with selectable assistance and USB-C charging output.

Technology

Linear Power Control (LPC)

Enjoy smooth, consistent assistance across levels 1–5, even as battery voltage changes. The system is designed to meet Australian e-bike requirements.

Integrated 17.5 Ah battery system

The lockable, removable battery sits neatly inside the frame and provides 630 Wh of capacity for longer rides. Protected cells and fire-retardant resin add an extra layer of safety.

RTC package

RTC means Rail Trail Commute. You get practical all-weather equipment including extruded aluminium mudguards, an integrated rear rack and battery-powered front and rear lighting.

Integrated Dual Beam LED lighting

The front and rear lights run from the main battery, so you do not need to charge separate light batteries. The rear light also flashes as a brake light.

MIK HD rack mounting

The integrated heavy-duty rack uses the MIK HD mounting system, making it easier to carry panniers, rack bags and compatible child seats.

Hydraulic brake power cut-off

The Tektro hydraulic brakes provide controlled stopping with large 180 mm rotors, while the brake levers immediately cut motor power when braking.

Precision cadence sensing

The enclosed fast-response cadence sensor activates assistance as you pedal and stops motor assistance when you stop pedalling.

Ergonomic upright riding position

The upright position and wide, swept handlebars improve comfort, visibility and control on longer commutes and rail-trail rides.
