M1 Pro

I purchased the M1 Pro, the bike has been solid.
I do recommend upgrading the brakes to the Hydraulic ones.
After about 400 miles I had 02 error, I then contacted Aipas support, they were super helpful.
The response time was with in 24hours.
Aipas sent a replacement controller and wire Kit right away.
Works perfect again!

Aipas M1- Max

To start with the packaging of the bike is amazing. The assembly was easy, all the needed tools were provided. This bike was bought for my wife who has never been on an E-Bike, but she picked it up easily. We both have the same model’s and we both highly recommended the step through frame. My wife said she was happy it was a step through frame because the bike is on the heavier side.

We also bought the upgraded wide seat which she loved. She loved how there was 3 different riding styles for this bike. She was worried she was not going to get the exercise that she was used to from her old road bike. But she was happy after her first ride. No regrets on the bike or the upgraded seat and front basket. The bike seems to be well built and also has the upgraded 52v 17.5Ah battery.

I'm very pleased with the Aipas M1 pro, has all the power I was looking for. Rides easily, suspension is awesome. I do like that the bike has back blinkers on the brake light. Bike is very well put together. I feel safe when riding. I have a rover cart my dog rides in on the back, I can't forget her. Picks up speed quickly and no problem with climbing hill.

Riding in remote Alaska

Overall, I love the bike!!! It gives me a lot more freedom than I had. I am a travel nurse in remote Alaska, I spend $120 a week just in cab fare to/from work. The bike is fast, I get to work in 15 minutes. Easy to pedal, love the pedal assist. The two down sides are, putting it together, I would have liked more detailed instructions, though the pictures helped. The rubber piece that covers the on/off button for the battery doesn't close and is constantly getting pushed in when I insert the battery, or when I try to close the cover. Again, overall, I love my bike!!! Bonus that it came in my favorite color(purple)!

Great ride

Just finished assembling my new ride, took about 1/1/2 hours. Took a 20 mile test ride, very happy. Got my first E-bike in 2019, just turned 4500 miles. This new bike is a lot different than my Rad City. It is going to take a few rides to get use to the extra 20 lbs. Bike arrive in 3 days. Would definitely recommend this bike.

I’ve had my M1 bike for 6 days and have already put 500 miles on it! If it wasn’t for all the rain and storms we’ve had I would probably have a lot more! That tells you how much I love riding this bike! What I like about it is that it is very comfortable, sturdy, easy to ride, and it’s been a head turner here in Indiana!

Excellent bike, great price point

I recently purchased the Aipas M1 Max with hydraulic brakes, and it has exceeded my expectations in several key areas. The bike frame feels incredibly sturdy, giving me confidence whether I’m cruising on pavement or taking it onto rougher terrain. The acceleration is excellent—smooth, responsive, and powerful enough to get up to speed quickly without feeling jerky.

The hydraulic brakes perform really well, offering strong, reliable stopping power and a controlled feel. It’s a noticeable upgrade from mechanical brakes and adds a lot of safety and comfort to the ride.

Shipping was also handled impressively. The bike arrived well‑packaged with no notable damage, and all components were secure and protected. The assembly manual could use better instruction and pictures but we were able to figure it out using YouTube videos if we had questions.

I had not taken it on a long range ride yet but plan to very soon.

Overall, the Aipas M1 Max delivers great performance, solid build quality, and dependable braking—definitely a bike I’d recommend for the price point.

Strong Bike

Bike assembled easily. First ride was very impressive. Climbing power is great, 1st gear in PAS 1 climbed my driveway which I have trouble with with my regular bike. I'm 70 and this bike has power. PAS 5 in 7th gear is fast.

Does it have a throttle

Aipas Bike LLC

Of course, all our e-bikes have throttles! And there are three modes. Pure electric mode, drive directly with the throttle;
Bicycle mode, turn off the motor and ride purely on pedals like a bicycle;
PAS mode, the motor is driven by pedaling, which saves effort and allows for a longer riding distance.
