Overview

A great fit for commuters, recreational riders and anyone wanting dependable electric assistance for hills, longer rides and light off-road routes.

The dyson Hard Tail Evo is built for riders who want electric assistance without giving up the familiar feel of a conventional bicycle. Its alloy hardtail frame uses hidden cabling and a lockable battery integrated into the frame, giving the bike a tidy appearance while keeping a generous 630Wh capacity available for longer rides. The 250W high-torque hub motor delivers pedal assistance through six selectable levels, with the enclosed cadence sensor designed to respond quickly when you start pedalling.

On the road, the Evo is a practical everyday bike with enough versatility for rail trails and light off-road routes. 27.5-inch wheels, 2.1-inch Kenda tyres and a 100mm Suntour XCM 30 fork help smooth uneven surfaces, while the fork can be adjusted or locked out for firmer handling on sealed roads. The 8-speed Shimano Altus drivetrain gives you useful gearing for flatter stretches and climbs, and the hydraulic Tektro brakes with 180mm rotors provide confident control when slowing down.

Choose this model if you want a comfortable, uncomplicated e-bike for commuting, errands, fitness riding and weekend exploration. The backlit LCD display shows key ride information and includes USB charging output, while automatic brake power cut-off stops motor assistance as soon as you apply either lever. With an adjustable seatpost, comfort gel seat, centre kickstand and puncture-protection sealant, it is equipped for regular Australian riding rather than occasional use.

The large 17.5Ah lithium-ion battery is fully protected, lockable and neatly housed within the frame for a clean appearance and useful everyday range.

Hydraulic Tektro braking

8-speed Shimano Altus gearing

A single 46T chainring and 12–32T cassette give you a straightforward range for flats, rolling roads and climbs.

27.5-inch wheels with puncture protection

The 650B wheel format balances stable handling with easy manoeuvrability, while Slime sealant adds protection against everyday punctures.
