Just arrived for the holiday weekend and I will be testing this bike for a beach city in Florida! I will update this review as I’m using it at work in a salt water and sandy environment. Initially upon opening box I immediately noticed that it has a really nice frame and high quality equipment! I was able to put it together in less than 20 minutes (ok my son helped or umm did it)! I have 30 years experience using a bicycle for patrol purposes! So the test begins 😁 First day using it on patrol! It has plenty of power and is fast! The brakes are fair and could use a little stronger braking power! Very smooth operation and easy to use! I’m 6’2” and 210 pounds and achieved a top speed of 34 mph! I only used 40% of the battery while using it for 8 hours on patrol and I’m going to use it again today without having to charge it! This is my 6th bike that I’ve tried and so far this is the heaviest and is hard to load for transport! Thus, I recommend a strong bike rack that has easy load! So far it’s a steal at the price point! One last thing, I hit the horn constantly because where it’s located on the bike! More to come!

After having ordered 2 of this bike and riding them around for a month here are my key takeaways to share. Challenges 1. I see they addressed the issue with people saying the front wheel fork gets bent in delivery by putting a bar with 2 nuts on it. Confusing part though was this was not reflected in any videos or the instructions. For a noob this presented a challenge but eventually I figured out what it was, its purpose, and how to remove it. Overall assembly took me about 30mins per bike. 2. On one of the bikes the back tire was flat day 1. Pumping it up gets it good for about a day but it needs a tube replacement. I don't know how to replace it but what I have gathered with these bikes is that they are easy to figure out with enough online research and some basic tools. 3. There are no holes to install things like bottle holders and phone holders. Get ones with clamps! Things I appreciate about it, 1. For the price point it has been a blast! It has gotten me on the road after work most days which is a huge win for my personal goals. It is a ton of fun and having the ability to change from 0-3 in assist is helpful for when I want it off to push myself or if I need it at some points on hills and such. It will not get you up a steep hill by itself! But it will assist you which is mainly the point. 2. It has an intuitive feel about it. The handlebars and seat are comfortable, the throttle and display are sleek and handy, I can tell it was well designed. 3. I have taken it on paved trails and roads just fine, as well as some easy trails. It is rather smooth overall. 4. Battery life is great if you don't use the assist by itself or on higher levels for long periods. When treating it like a motorcycle or trying to go fastest it will die in about 2hrs of riding. But used as a gentle assist I got the same distance in that would normally cost me about 75% of my battery in about 10%. Used as a tool it is rather efficient and can last multiple trips. I am sure with time as I get stronger and build endurance I can make the battery really last. If you are looking for a fun entry point to an ebike that is well thought out and has some pep to it to get you out there then look no further! This bike is an awesome e-bike purchase!

This is my very first ebike. I was a bit skeptical at first but I am not disappointed at all. Easy to assemble, great quality, price is just right, very durable, it's a bit heavy for me but it is very comfortable once you start riding it. Overall, I really think it is a great product for the price I paid for.

Im a 6 ft 4 in man and This bike is amazing I really don't know much about there compilation but this completely changed my life went from a hour walk to work at night and in the morning to a 15 minute ride . I wake up every time wanting to ride this bike and I'm a lazy dude it's absolutely fun just to rip around my town . The tires need to be inflates they both shipped at 10 psi . It took me not even 30 mins to put it together and I was off to the races and it did come with a 75% charge . Idk if it me going full rip all the time but you definitely dont get 40 miles out of a charge but that's not that important to me . And last thing is the hole electric system is 36 Volts so don't try and diy splice and wire in your own led for undergrowl it will cause the leds to burn up and no longer work I should have used my multimeter and read the output voltage to the headlight first but you learn from your mistake but still and amazing bike for me

I got this bike about 3 months ago, and I've ridden about 270 miles on it so far. Aside from typical bike maintenance with mileage like that (brake adjustment, chain lubrication, etc.), I have only had one issue with the bike, and that was a failed controller. Luckily, I worked with Jasion Support and they were super good about sending me a new controller, a new throttle, and a new pedal assist sensor just to cover all of the bases. It was super easy to replace, and it again works perfectly! The motor is super responsive and gives plenty of push. The overall gist of the power is that it feels like it basically doubles my own pushing power, especially at higher speeds. I was able to customize the bike to the way I like it by turning off Pedal Assist and just enabling the throttle so I am in more granular control of the power, and I love the fact that this bike allows you to twist the throttle to get power from a dead stop (That was one of the reasons I got this bike in particular). The 7 gears it has are plenty given the fact that you have a motor to help with low-speed maneuvering, and I have had no issues with the derailleur aside from a quick adjustment. I would recommend waterproofing the bike or keeping it in a dry place, because it isn't exactly waterproof from the get-go, but the times I have ridden in the rain were totally drama-free. Given Jasion's excellent customer support and their stood-by year long warranty, I would absolutely recommend this bike to any e-bike newcomers. Just remember to factor in the cost of shipping the bike in the overall cost haha!

The bike will be great for the first 100 miles, After a year and 100 miles the battery will not hold a charge and the bike will shut off showing almost a full charge. Do not buy!! Seller will not help you outside of a year and there is no warranty on the battery which is the most expensive part of the bike. Do not buy! Seller will not help you with faulty batteries! Not a good seller. Chinese battery with cheap cells that do not last!!!

Great bike and took about 30 minutes to assemble. Accurate description for speeds of 35 mph. Battery life is good and the bike looks really good. It’s a heavy bike and I recommend it for adults
