First I'd like to start by saying that I do all of my own bike maintenance and have for some time, so I'm familiar with cycling and have had a few e-bikes. I did 3k miles in 6 months on my last e-mountain bike, and well over 10k on the previous before that. I'm also a volunteer bike mechanic in my city during my free time. I've had this bike for a few weeks and have put a few hundred miles on it as I commute 20 miles a day. Initial impression is pretty standard for partially assembled bikes like these. My bike came pretty early, I think half a week. They did a very good job wrapping all of the components with protective material and plenty of cushioning for the sensitive parts. The tires came fully inflated which was rather surprising, but welcomed for those who want to ride right away. I put my own road tires on these right away, so I can't say to the stock tires. They look fine and I'll use them in the winter. The materials of the bike are pretty well made all around with one part that makes me nervous: the LCD display is mounted on a somewhat cheap piece of bracket/mount on the handlebar. You could easily snap the screen off the mount if you put enough force or flipped the bike upside down to change a tire. It's easily adjustable, so just be aware of it. Size & Stability: This is a huge, heavy bike. This has positives and negatives. Being so heavy, it feels extremely stable on the road and at higher speeds. Cracks and bumps that would make me grip my mountain e-bike are barely noticeable. At higher speeds I thought the LCD speedometer was wrong since it felt slow; nope, the bike is just very smooth. A con to the weight is carrying it. I had to carry this up a flight of stairs and it was pretty difficult. I'm 5'10" and lift heavy stuff all day, so taking this up and down stairs is very impractical if you aren't too strong. If you get off and don't hold it tightly it WILL fall and possibly take you with it. Be careful. Performance: This thing is FAST. They list it at 28+ emphasizing the plus. I don't know if I got a higher wattage motor or lucky parts, but mine easily goes into the 30s at full charge and feels like there's still power. I let off the throttle at 31 because it's too much for a bike in my opinion. I don't take it past 25 much, and I don't recommend anyone do this without proper gear and tires. That being said, the PAS levels are alright and pretty standard with levels 1-5, 1 being somewhere around 8mph, level 2 15mph, and 3 (which I usually keep it at) 20mph. 5 is full power which I use the throttle with. The computer sends too much power immediately when pedaling at level 3 so it will jerk you and take off, then eases up to 20/21mph. You may be able to change this in the LCD settings (mine came unlocked), but this is more personal preference. The LCD has lots of settings and controls that I haven't really messed with, which is very welcomed as other brands typically lock them down, which is a shame for us who like to tinker. The brakes are okay. I adjusted them immediately before even riding the bike through an alignment as I do with all of my bikes (YouTube will show you this, it's easy). They stop fine, but are rather noisy. The pads are somewhat cheap which is what I expected, but they're enough for a bike of this size and speed. The rear rotor is thin so sometimes when accelerating quickly it will rattle. My previous e-bike did this and I find it very annoying, although it doesn't affect anything stopping wise. Battery: The physical battery itself is huge. My previous EB-M1 was half the size but also half the range. Their range estimates are not exaggerated and I was pleasantly surprised as most other companies flat out lie or stretch the truth. Being familiar with e-bikes, I know how to stretch the range and did so on this bike one day. I did somewhere between 30-40 miles while keeping the motor at PAS 2 and got home with 50% battery. I ride 20 miles a day total to and from work, 10/11 miles each way. When I get to work I usually have 80-85% battery left which is exceptional. Other things I like: The rear rack is great in my opinion. It's very hefty and matches the bike well. I already put saddle bags on it and plan to use it to haul my camping gear. There's torque arms already installed which connect to the rear rack but look like they don't need to be. Cheaper e-bikes sometimes won't include torque arms which is incredibly dangerous and could cause the acceleration of the motor to rip out the rear wheel! The headlight is very good as well. It seems to be a projector system and is more like a motorcycles. It spans wide left and right but has a distinct horizon cut off at the top of the beam which prevents you blinding people, a very nice touch. Summary: This bike has some budget quirks that most budget e-bikes do, but nothing that really stuck out to me worth taking a star off. For the price the EB5 Max is absolutely 5 stars. Their speed and range specs are true, frame and build quality are good, and it's also a good looking bike. The LCD mount should be upgraded by Jasion in the future.

Such an awesome bike! I love to ride trails in my area as well as DoorDash so this has not only made it fun, but super easy! It was defiantly costly but well worth the price. Not only is it very comfortable when riding on for long periods of time but it looks awesome, and the size fits me. It's very durable and has great stability when riding on uneven paths as well. It is a little heavy but I would expect it from something as cool as this!

The good: Showed up packed well, assembly was easy and straight forward. Battery was fully charged out of the box. A lot of fun to ride. Seems really well built, heavy. The bad: Both tires slowly loose air, about 8 pounds overnight. Front tire starts vibrating around 15mph, will have to look into getting this fixed. Size: Bigger than expected, I'm 5'10 and can put my feet flat on the ground with the seat in the lowest position. 4.5 stars, would be 5 if not for the issues with the tires

The bike base comes mostly assembled. Does, tools put everything together if you need them. Tools are adequate and did the job. I actually kept the tools that came to fit to put the bike together and now I carry them in a poach in case I need them for if I’m on the road. It took me about 45 minutes to assemble the bike. It does come with a nice follow along video to watch. I’m not that mechanically inclined, but it was easy enough for me. I wouldn’t be intimidated by it. I’ve driven the bike now for about 20 miles and so far so good performance is good. I’m a big guy so I did replace the seat as it was uncomfortable. I’ve not been on a bike ride long enough to test the endurance of the battery but for the amount that I’ve gone it has done well. Sidenote: notice the pictures that I’ve posted. The basket came with miscellaneous scratches in the paint I feel they could’ve done a better job Packaging this but as you can see from the pictures, they do do a pretty good job it could be. It’s just incidental scratches from shipping. Would I buy this bike again? Yes 👍 I recommend it to a new person absolutely. Shipping went well good communication with the sales department and shipped on time. I also bought a second bike.

Fast shipping! I received my bike in four business days! Assembly was easy in less than an hour. The quality of all the parts and pieces was better than expected! I now have 115 miles on the bike with no issues at all! The value for my money has exceeded my expectations and I have had so much fun riding where ever I need to go! I can carry it right up my stairs so portability hasn't been an issue. The extra rear rack comes in handy for carrying packages home!

Againstmy better judgment my child wanted this bike and of course they tell us to keep the box I did. It’s prestige condition, but the control went bad along with the display. No one in my area will repair it and if I have it to prepare it on my own they’re gonna charge me $85-$95 an hour and they want to resend me parts and $50 compensation. I bought the insurance and the insurance won’t even pay out because of you have to have one year with them. What a rip off these people are almost cause my son to get hit by a car because the throttle takes off on its own without you, touching it. This product should be taken from off their website. It is dangerous. Beware beware! Shame on Amazon for not standing with the customer knowing they have bad reviews. I’ve sent endless pictures endless videos and they’ve admitted that through their communication that it’s a faulty, controller and display and expect me to pay another $300 to get it fixed even if they give me the parts no one will do it for free and no one is a representative here and then they think I believe them that they’ll give me my reimbursement to have it parts put on it I don’t think so. Shame on Amazon once again for not standing with their customers they know they have bad reviews. So it sits in the garage, not able to even ride it.

I'm so happy with this bike. I charged it once and I've been riding around our neighborhood and beyond for the past few days. Me and a buddy put it together in about 30 minutes. It seems super sturdy. It accelerates quickly and goes faster than I really need. It looks great and im super happy with the price. Im taking it to Silver Falls state park in a couple of days. It has 5 speed assists and on number 5 it goes fast. Gonna get my wife one soon. For the price, I highly recommend it!

Great bike, easy to assemble, shipping was great, no problem so far. The bikes pedal assist works really well, with pedal assist on level 2 (15 mph) you can effortlessly pedal and go about 20 miles and still have 60%, it does help the battery to stop a few times. I did notice the tires arent that great because after putting about 100 miles and a litle trail rides I got a flat because the tire flex caused its steel belt lining to break and the splayed wire punctured the tube. I would upgrade the tires
