Is the Aairsk SU7 Electric Bike road legal in the UK?

Many e-bikes are supplied with a UK‑compliant assist setting (25 km/h / 15.5 mph). If you use higher-speed or higher-power modes on public roads, it may be treated as a motor vehicle and need registration, tax and insurance. Always ride to the current rules.

Is the Aairsk SU7 Electric Bike easy to assemble?

The Aairsk SU7 Electric Bike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the Aairsk SU7 Electric Bike water resistant?

The Aairsk SU7 Electric Bike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.

Description

The Aairsk SU7 step-through electric bike is designed for comfortable, easy-going cycling. A low-step frame and compact 24-inch wheels make getting on and off more convenient, while its practical equipment suits everyday outings and relaxed leisure rides.

Key Features

Low-step frame for easier mounting and dismounting.
24-inch wheels for a compact, approachable riding feel.
36V 13Ah battery for dependable electric assistance.
Shimano 7-speed gears and front suspension for comfortable, adaptable riding.
Rear rack, disc brakes and NFC activation for everyday practicality.

Easy Access and Everyday Comfort

With no high crossbar to step over, the SU7 makes frequent stops simpler. Its comfortable riding position, front suspension and manageable wheel size are particularly appealing to anyone looking for a more relaxed alternative to a traditional mountain bike.

Practical Electric Assistance

The battery works alongside Shimano's seven gears to support comfortable pedalling on varied routes. A rear luggage rack adds room for compatible bags, while NFC keyless activation makes the electrical system easy to access. The SU7 brings useful features together in a 24-inch electric city bike with a welcoming design.

Step-through city comfort

The SU7 uses a low step-through frame that makes mounting and stop-start riding much easier in town. A more upright riding position and 24-inch balloon tyres help smooth rough tarmac and keep the bike feeling stable at low speeds. Its a great fit for relaxed commuting and everyday errands.

36V 13Ah removable battery

With a 36V 13Ah removable battery, you can charge on or off the bike depending on where you store it. TrailSurge lists up to 40 miles of range for the SU7 (real range varies with assist level, rider weight and terrain). Charging time is typically around 5 hours.

Daily-ready spec and kit

A rear hub motor paired with 7-speed gearing gives you flexibility for flats and gentle climbs. Mechanical disc brakes support consistent stopping, and the front suspension adds comfort on imperfect roads. You also get practical commuter touches like integrated lighting, a rear rack and mudguards, plus an LCD display with card access.
