TWO Aipas M1 max bikes are more fun than one!
I ordered (2) Aipas M1 max bikes. I received them in less than a week. They came packaged very securely in flat screen tv boxes. Smart idea!
Assembly was straight forward with well laid out directions and online videos. In less than a couple of hours I had them both assembled.
I ordered an oversized saddle for me, and my wife wanted the "Big Butt" noseless saddle for hers. My skepticism of the noseless saddle was unfounded. It works great for her 70 year old butt. I'm 63 years old and I might just order one myself.
Both of our bikes have rear baskets which should prove to be useful on longer rides.
My wife is 5'3" on the short side of the 5'5" rider heigth. I took a chance that I could shorten the frames saddle tube by 1" and still meet the saddle to pedal inseam requirements for her. It works like a charm.
We only have about 35 miles on them so far, but I see no reason why these beastly E Bikes won't stand up to thousands of miles and years of fun.

We bought our combo for our 50th wedding anniversary. Our plan is to ride as many bike trails and beaches as possible this year. These bikes are up to the task. With all of the current upgrades and the apparent quality of materials and assembly, I look forward to a long relatively carefree riding experience. My children have ridden our bikes with us, resulting in Aipas purchases by them.

One bike is great arrived in a decent amount of time both both of the two bikes I bought the child trailer is great. I’m having a service issue and it’s been a week now waiting for the replacement part so I could put it on so I’ll be able to use the second bike. I will update my review once we can get both bikes going and out for a good ride.

My husband has been wanting an ebike and I started looking at bikes Labor Day weekend because of sales. I don’t remember how I ran across this brand and the price caught my eye. We watched several videos on YouTube on a few brands and kept coming back to Aipas. We didn’t find any negative reviews or videos while doing our research. These bikes came packed extremely well!! We have ridden a few times and love these bikes. We have a trip to FL coming up soon and are excited to take the bikes with us. We also camp a lot here in AR and can’t wait to start taking the bikes on a lot more adventures. Some very close friends of ours liked our bikes and are looking at purchasing a pair as well. We give these bikes a 10/10.
