The AAIRSK SU7 is a 24-inch step-through electric bike designed for comfortable everyday mobility. Its low-step frame makes getting on and off easier, while a 250W rear hub motor, Shimano 7-speed gearing, front suspension and practical everyday equipment make it well suited to commuting, errands and leisure riding.
Rather than focusing on aggressive off-road performance, the SU7 is built around a simple idea: make everyday electric riding easier, more comfortable and more practical.
Easy Step-Through Design
The SU7 features a 24-inch step-through frame, allowing riders to mount and dismount with less effort than a traditional high-step frame.
This makes it particularly practical for stop-and-go city riding, regular errands and leisure journeys where riders may get on and off the bike frequently.
The compact 24-inch wheel setup also gives the SU7 a more manageable everyday feel without turning it into a small folding bike.
250W Electric Assistance for Everyday Riding
The EU/UK configuration of the SU7 uses a 250W rear hub motor, providing smooth electric assistance for daily journeys.
The bike supports multiple riding options, including:
- Pedal
- Pedal Assist
- Electric
Electric assistance on the EU/UK configuration is limited to 25 km/h (15.5 mph).
This gives riders the flexibility to use traditional pedalling when they want more exercise, electric assistance when they want to reduce effort, or the applicable electric riding function according to the configuration and local riding rules.
Built-In 13Ah Battery
The SU7 uses a built-in 13Ah battery integrated into the bike.
Unlike a removable-battery model such as the S600, the SU7 battery is not designed for routine removal. Charging is therefore carried out directly on the bike.
This integrated design keeps the battery securely positioned within the frame while providing the capacity required for everyday riding.
Up to 52 km Estimated Riding Range
The SU7 offers an estimated riding range of up to 52 km under suitable riding conditions.
Actual range can vary considerably depending on rider weight, terrain, gradients, temperature, tyre pressure, riding speed, riding mode and the amount of electric assistance used.
For that reason, the 52 km figure should be treated as an up-to estimate rather than a guaranteed riding distance.
Comfort for Everyday Roads
A front suspension fork helps reduce vibration from uneven streets, paths and everyday road surfaces.
Combined with the 24-inch wheels and comfortable riding position, the SU7 is designed primarily for:
city streets, cycle paths, park routes, commuting and leisure riding.
It is not positioned as a technical mountain bike for demanding off-road trails.
Shimano 7-Speed Gearing
The Shimano 7-speed drivetrain gives riders additional control over pedalling effort when road conditions change.
Lower gears can make starts and gradual climbs easier, while higher gears are useful when maintaining speed on flatter roads.
The gearing also means the SU7 remains fully usable as a conventional pedal bicycle when electric assistance is not being used.
Front and Rear Mechanical Disc Brakes
The SU7 uses mechanical disc brakes at both the front and rear, providing controlled everyday braking across normal commuting and leisure riding conditions.
As with any bicycle, braking performance can be affected by road surface, weather, tyre condition, brake adjustment and rider technique.
Practical Equipment for Daily Use
The SU7 comes equipped with features intended to make everyday ownership more convenient.
A rear rack provides useful carrying capacity for compatible bags or everyday items, while full-coverage fenders help reduce road spray in wet conditions.
An LED front light provides additional forward visibility in low-light riding conditions.
Together, these features make the SU7 better suited to practical everyday use than a stripped-down recreational e-bike.
Size, Weight and Load Capacity
The SU7 uses a 24-inch wheel setup and weighs approximately 23.5 kg.
Its listed maximum total load is:
Up to 150 kg
The maximum load includes the rider and anything carried on the bicycle.
Actual rider fit can vary according to height, leg length, saddle position and personal riding preference.
Is the SU7 Difficult to Assemble?
The SU7 arrives mostly pre-assembled, so customers do not normally need to build the bicycle from individual components.
Only a small number of final parts generally require installation or adjustment before the first ride.
Before riding, customers should follow the supplied instructions and check important items such as brakes, handlebars, pedals, tyre pressure and fasteners.
Who Is the SU7 Best For?
The SU7 is particularly well suited to riders looking for an accessible and practical electric bike for:
daily commuting, local errands, park and cycle-path riding, leisure journeys and other everyday trips.
Its main strengths are the step-through frame, manageable 24-inch format, electric assistance, front suspension and practical everyday equipment.
Riders primarily looking for aggressive trail riding, large suspension travel or technical off-road performance may be better served by one of AAIRSK's mountain-oriented models.
Warranty and After-Sales Support
The SU7 includes a 2-year warranty for the frame and 1-year coverage for the battery, motor, controller and other eligible original components, subject to the applicable AAIRSK Warranty Policy.
AAIRSK also provides after-sales assistance for troubleshooting, product guidance and eligible warranty issues, with compatible replacement batteries and essential parts available for supported models.
Road Use in Europe and the UK
The SU7 is a pedal-equipped electric bicycle with fully functional pedals.
The EU/UK road-compliant configuration uses a 250W continuous-rated motor with electric assistance limited to 25 km/h (15.5 mph).
In Great Britain, an e-bike that meets EAPC requirements—including functional pedals, a continuous-rated motor of no more than 250W and assistance that does not propel the bike above 15.5 mph—does not require a driving licence, vehicle registration, road tax or motor insurance. GOV.UK
Under the EU framework, conventional pedal-assist cycles with a continuous-rated motor of no more than 250W are excluded from the L-category type-approval regime when motor assistance stops when the rider stops pedalling and is progressively reduced and cut off before 25 km/h. National rules concerning age, helmets, riding locations and other requirements may still differ. EUR-Lex
Customers should use the market-specific configuration supplied to them and follow the applicable local cycling rules.
Final Overview
The AAIRSK SU7 is designed as a practical step-through electric bike for everyday riders rather than a high-performance off-road machine.
Its combination of a 24-inch step-through frame, 250W rear hub motor, built-in 13Ah battery, up to 52 km estimated range, Shimano 7-speed gearing, front suspension, mechanical disc brakes, rear rack and full fenders gives it a clear role within the AAIRSK range:
comfortable, accessible and practical everyday electric mobility.
