The Goldilocks of Electric Bikes - It's just right!

I tested a few e-bikes that felt too flimsy or were way over the legal power limit. The Aairsk SU7 is the perfect balance. It has enough power (a very zippy 400W/748W peak) to be fun and practical, but it's fully compliant and feels safe and controlled. The build quality is solid, not cheap. The battery range is just right for my needs. The step-thru frame is just right for easy mounting. It’s not overly complicated; it's a thoughtfully designed, high-quality product that does exactly what it promises. I couldn't be happier with my purchase

Surprisingly easy assembly and instant fun!

I was a bit nervous about assembling an e-bike, but the Aairsk SU7 arrived well-packaged and about 90% assembled. It took me less than 30 minutes to attach the front wheel, handlebars, and pedals. The instructions were clear. The moment I powered it on and took it for a spin, I was blown away. The power delivery is smooth, the bike feels incredibly sturdy, and everything just works as advertised. The rear rack was already installed, which was a nice bonus. A fantastic out-of-the-box experience that led to an even better riding experience.

The card key unlock is a genius feature!

I'm a tech guy, and the LCD display with card access immediately caught my eye. It’s not a gimmick; it's incredibly convenient. A quick tap of the card and the bike is on. The display itself is sleek and shows all the crucial data at a glance. Beyond the tech, the bike is a fantastic performer. The 36V 13Ah battery gives me a reliable range that I don't have to stress about, and the Class 2 throttle is perfect for when I need a quick burst of speed without pedaling. It’s a modern e-bike that perfectly blends smart technology with robust, legal performance.

Feel safe and seen, day or night.

My number one priority was safety, and the Aairsk SU7 delivers. The bright headlight and taillight make me feel visible during early morning or evening rides—a feature that should be standard on all e-bikes. The step-thru frame is not just about comfort; it's about stability. I can easily put both feet flat on the ground at a stop, which is a huge confidence booster. The full fenders are a lifesaver on wet roads. The fact that it has this powerful, legal motor and a removable battery for secure charging is the icing on the cake. A wonderfully safe and well-designed machine.

Finally, a bike that laughs at hills!

I live in a notoriously hilly area, and my regular bike was collecting dust. The Aairsk SU7 has changed everything. The 400W motor, which the specs say can peak at 748W, is an absolute beast. It provides a massive boost that makes steep inclines feel almost flat. I was careful to choose a bike that complies with the 750W federal limit, and this one delivers incredible performance within that regulation. The pedal-assist is so smooth and the Shimano 7-speed gears let me find the perfect cadence. I feel safe and powerful on every ride. If hills have been holding you back, this is the bike for you!
