My goto for E-bikes!

Wonderful 5-tier customer service!! Excellent packaging, presentation and easy assembly, reliable and impressive shipping. I just purchase 2 of the A4’s but considering one of their mountain bikes after having an awesome experience with my last purchase. Once I engaged the peddle assist, I was amazed. I’m coming from only tradition bicycling experience and never put much thought into e-bikes. This is a whole new level and Aipas helped deliver this new experience to me. I had excellent presale and post sale correspondence with customer service. They are super nice and great to work with. I did not receive a promotion or get anything free for writing this nor am I affiliated with the company whatsoever. I was very skeptical at first because I wasn’t familiar with the brand. The company treats you first class before take off and after landing. You won’t regret and I guarantee you will be recommending them to all your family and friends like I have. I love my A4 but would love to have an M2 Pro in my arsenal. If you’re having trouble deciding a color for the A4, I got the turquoise color A4 for my girlfriend. That color is beautiful in realtime! Mix it up with either orange or pink accessories and it pops!

Very pleased but confused

Very confused because we ordered a 2 bike combo and received only one tracking number. The first bike arrived according to that number. The second came two days later. They must come out of different warehouses. They earn that this is a possibility, two different delivery days. They did come in a timely manner, easy to put together and awesome to ride.

Excellent Ride and outstanding Service!

AI recently purchased two Aipas A4 Gentry bikes and couldn't be more impressed. From the moment I unboxed them, I could tell they were a quality product. The bike is sleek, sturdy and delivers a smooth powerful ride that makes every ride enjoyable.
What truly sets Aipas apart, though, is their exceptional customer service. They were responsive, helpful, and genuinely cared about my satisfaction. I had a few questions during setup, and their support team walked me through everything with patience and professionalism. It's rare to find a company so committed to both product and excellence and customer experience.
I highly recommend Aipas to anyone looking for a reliable e-bike and a brand that stand behind its customers. A+ all around

Bought a pair of Aipas A4 bikes and love them

I purchased and received my bikes in a timely manner and at a great price. They are very well made and very sturdy and of course pretty fast. Easy to ride and super fun. I would recommend to friends and family, also anyone looking for an e-bike. We bought them to take when we go glamping. To cruise the area without driving a car.

A4 Gentry Combo

Both bikes arrived earlier than expected, one 3 days before the other. Packer very well. Easy to assemble. Have not gotten to ride then much due to the weather. However, bikes seem to be very well constructed and are very comfortable. BMX style handle bars are a plus and add to the appearance. Unexpected surprise was the rear turn signals. Fold up nice and can both be placed in our Lincoln Nautilus which we tow with the motorhome. Would definitely recommend these bikes. Looking forward to putting some miles on them.

Lots of FUN!

Great for my commute to work and lots of fun to ride! This ride is Awesome!! All of my coworkers think it’s great and some are looking to buy one themselves. I added a bottle holder and the wood basket to make it even better.

Much more advanced Ebike

I got a smaller one last year around March for my mom, who is 4ft 11in and that one works well for her. She used that one for daily commute from our house to the community pool. One big concern is the whole right handle is for speeding up and my mom needs to be very careful not to accidentally twist it. Another issue is we have a big hill right outside our house and it doesn’t have strong horsepower to support the small Ebike goes fast enough.

What we really like about our initial purchase is the customer service from the seller. We did experienced some problems with the battery after 5mo of purchase. The seller’s responses were with patience, very detailed, and they sent over the parts within one week. I also got a flat tire once but that is not included in the warranty. Even though, the seller responded my email very quickly and patiently with possible solutions.

When my husband wants an Ebike for daily commute, I checked this seller without searching for other brands. Good things for this bigger one are: easy to assemble, huge & fat tires makes it very sporty, space for additional storage both in the front and back, and the half-handle for speed-up instead of the whole-handle. My husband is 6’2 and the lowest seat position is good for him (not for me who is 5’2). If you want to ride it like a regular bike it would be like doing exercise—the Ebike is indeed very heavy. And another advantage for this one compared to the smaller one: this one comes with one pair of keys-for the battery removal and Ebike turns on.

Versitle...

With almost 250 miles on it since I purchased this e-bike; I can honestly say I LOVE it!!! I have used it to get around the city exclusively with a few 17 mile rides included. I exclusively use pure electric mode. The bike averages about 28 miles in pure electric on a full charge.

Optimizing time with fun

Looking for an alternative transportation, I looked for a bicycle that would commute home and work. It's a 20-mile journey and so I looked for an alternative that would give me comfort, safety, autonomy and freedom. I found it by purchasing one the aipas A4, which saved me time and the opportunity to enjoy the scenery along the way. It was an excellent acquisition.

Perfect exercises for a 79 year old senior. I like the step through design.

Initial impression of this bike is that it’s a quality product and a good value for the money. A lot of thought went into this bike, from the shipping packaging to easy assembly for the new electric bike rider. This is a powerful bike that takes over my pedaling when I come to a hill or grade, making exercise a little less difficult and bike riding less demanding. I find that it’s easier to control when you start peddling with the power off and once you are under way, turn the bike on using the lowest pedal assist mode and then throttle (safer too). So far, I love it!
I would like to do a follow-up review after about 6 months and Summer use is complete.

Great economical electric bike.

Strong motor with a nice amount of torque. My teen had a smaller version from the same company and this is a nice upgrade. The dual suspension and larger tires make for a nice ride. Though the brakes are not hydraulic, they are still large with great stopping power. Overall the bike looks great and is an awesome commuting bike for a student.

Honest and very customer service oriented people

I received my new e-bike but the seat was too high for me. My husband adjusted it the best he could but still too high. I emailed company for advice and the sent me a shorter rod at no charge and continued to follow up on status. It worked great. I highly recommended this company and its people are awesome.

First impressions are "WOW"

I just received and set up the bike today, and rode a couple of miles. So far, I am very impressed. I have never owned an electric bike before so I'm by no means an aficionado, but I think this one stands well above the others in this price range.

First, the packaging. Wow was this thing packed well. Plenty of foam and a ton of zip ties kept it all safe and snug in a thick cardboard box. One could beat the box up during shipping, or drop it out of the back of a truck driving down the highway, and I'm sure the bike would survive without a scratch. These guys could teach plenty of other manufacturers a thing or two about how to package heavy equipment.

Second, the quality of construction surpassed my expectations. The frame welds are absolutely perfect. The paint and powder coating are perfect. Every screw that I worked with came with thread lock on it. Fit and form is perfect. All adjustable locks (seat, handlebars) and every bolt and screw were tight and required no adjustment. The only accessory that did need to be tightened down was the power switch on the left handlebar, which took two seconds to do.

I do have a couple of suggestions: First, you may need to flip the bike upside down to install the front wheel. I struggled with mounting the wheel but after flipping the bike over, I discovered that the brake caliper was partially closed and would not allow the disc to push through between the pads. After fiddling a bit with the brake it opened up, allowing enough space for the disc. Second, I watched a YouTube video and picked up an idea to attach the front headlight to the front fender bolt instead of the basket. That way, the light will point to where the wheel is turned, plus it looks much better. There is more than enough cord length to make this modification.

The front shocks are adjustable, but there is no explanation in the manual about this feature.

As mentioned, this bike mechanically is built like a tank. Time will tell how well the electronics hold up. As far as value is concerned, this bike is better looking and far more beefier than the ones I've seen at our local warehouse club in the same price range.
