So I reeeeallly wanted an E-Bike, just a nice pedal assist that's legal in my state. This is a Class 2 so good most places. I looked at many here, direct manufacturers, and even check my local bike shop. Ultimately I took a chance on this Gotrax and I'm glad. It's on the lower end price-wise, but still an investment so I wanted to go with an American manufacturer with support and replacement parts if needed. Honestly it IS entry level, but before dropping $1k+ on a bike I wanted to be sure I liked it! Good news, I do and plan to stick with this one! I've had it 4 months and it's been reliable and rides well. It's not as heavy as some I tested, maybe 50 lbs, and while assembly wasn't the easiest it wasn't too hard. All needed tools were included and the allen wrenches are actually good. The disc brakes did need adjusting, and it took me a little while and a couple videos to get right, but work well. The pedal assist and throttle are excellent, I only use the throttle on cold starts at lights really. The power levels 1-5 basically correspond to assistance up to 10, 12, 15, 18, & 20 mph as far as I can tell. It doesn't have a speedometer, but phone apps work great (I highly suggest a phone mount) and how often do you really need to know? If you have it at level 2-3 and aren't winded you're probably doing 12-15 max and that's fast enough for me. So overall: It's super cute, rides well, a bit barebones but solid and reliable to this point. I've had fun customizing it as well as riding and am somewhere around 200 miles on it so far.

Great Quality e-bike. Easy to assemble, very sturdy and reliable. Liked the the fact you can have option of riding it as a bike only and using the electric when needed. Love the handlebars reminds me of a beach cruiser look. The gear shifts are smooth and easy to use, the e-modes are relatively simple and functional. The bike rides smooth and handles great. The batteryand lock are in perfect location and easy to access. I would say the only con to the bike is theseat, it is veryhard, but fixabsle with a gel seat cover. If your getting into e-bikes I would recommend this Dolphin.

I’ve been really happy with the Gotrax Dolphin e-bike so far. This is actually my second Gotrax bike, and while this one doesn’t fold like my previous one, I’ve come to appreciate the added sturdiness and simplicity that comes with the fixed frame design. What I like most about this bike is how straightforward it is to use. It still has both pedal assist and a full electric mode, so you can ride however you’re feeling that day—whether you want a little exercise or just cruise without pedaling at all. The transition between modes is smooth and easy. My favorite feature by far is the handlebars. They’re more ergonomic than the typical straight bars you see on a lot of bikes, and that makes a big difference on longer rides. They feel natural, comfortable, and reduce strain on my wrists, which I didn’t realize I needed until I tried them. Overall, it’s a solid, reliable e-bike that does exactly what I need it to do without overcomplicating things. If you’re looking for something simple, comfortable, and versatile, this is a great option.

Cheaply made. Spent a majority of the day trying to tighten the screws but not matter how tight the parts were things were able to move. The seat constantly kept sliding down. The handle bars would always misalign. After an hour of that I decided to ride it just down the block and the handlebars still misaligned and almost caused me to fall off. I stopped at a bike stop near by and spent another 30 mins tightening the parts at the point disassembling it and putting it together. Went for another ride and the front wheel completely fell off while I was on the street. Happened in the middle of the night so I couldn't find all the pieces ended up leaving it on the side of the road as trash. Worst birthday present ever Update on Customer Service: The next morning i called GoTrax directly and talk to a very rude representative she wasn't sincere and sounded like she didn't care. She told me to just get the refund from amazon only if i returned the bike. Eventually amazon did process the refund so that door is closed. Now the month is almost over and I just recieved an email from this company that sounds AI generated one key give away was that they copied my review word from word and stated they will give me refund if I returned the bike. They wrote that on the same paragraph where I stated that this bike is damaged and in the bushes somewhere. I hope I get an actual human to read my response to this email.

I am absolutely loving this Gotrax Dolphin e-bike. The 26" size is perfect and it feels incredibly sturdy and well-built. The ride is smooth, and the pedal assist makes tackling hills completely effortless. I’ve been using it for daily commuting and casual weekend rides, and the battery life has been impressive—it easily lives up to the advertised range. Assembly wasn't overly complicated either. Highly recommend it if you're looking for a reliable, high-quality electric bike!

Picked this electric bike up for my wife for Christmas - she loves it. It was fairly easy to assemble, save for the front disc brake, which was confusing. I found the assembly instructions written both in a miniature font and unclear - the images were so small they were not helpful. But once assembled, the bike sails! It has a powerful battery and easy-to-learn functionality. The pedal assist is surprisingly powerful and fun - and the magic 'no pedaling at all' feature is a helpful bonus. The bike is very comfortable in a more casual biking way than an exercise way - you ride more upright as opposed to a 'racing' posture, which my wife also likes. For the price, I don't think this bike can be beat. It is high quality and well thought out. Aside from the assembly instructions, which were lacking, I would highly recommend.

1 YEAR UPDATE !! 7/2/2025 Purchased - May, 2024 I use the bike 6 out of 7 days a week. The battery is still in perfect condition and lasts as long as it did day 1. I charge the battery overnight or during the day when it hits 20%. I noticed that running the lowest setting (1 - 5 speed setting) is just a slower build up to max speed. I use the first setting and pedal, saving battery and going just as fast as the 5th speed. 5th speed gives a much quicker speedup from a stop. --------Original review before update-------- Compared to a regular non-electric bike, this has made getting to work MUCH easier. I ride 8mi total (4 there, 4 back) and the battery drops from 100% to 80% using PEDAL ASSIST and THROTTLE. It dropped to 60% when I mostly used throttle. This makes getting uphill possible without breaking a sweat. It has improved my quality of life a lot, being able to get to work FASTER, and less exhausted, while still being able to exercise like a normal bike. I’ve been charging it to full after I get home and let the bike sit for a little while. I have never built a bike, and it was VERY EASY as long as you follow the directions. BUT……. The breaks on both wheels were too tight and I had to fidget with them for a couple hours to get them to stop making a grinding noise. IDK if there is an easy way of fixing that, it took me a while of straight tightening and loosening the breaks. ^and im pretty sure I made the breaks a little less powerful by fidgeting with it with no knowledge of how to do it the correct way, but the bike makes no noise, and breaks still work perfectly. —-> look up a YouTube video on how to stop breaks from making noise. There’s a way by loosening the breaks, PRESSING your breaks, then tightening them. That fixed it immediately, just look at multiple videos and try to find someone show that specific way. The little light reflectors on both wheels came loose, I knocked both out of place when building the bike. I just pushed them back into place and they haven’t moved while riding. I’m only putting that in the review to try and let people know that it’s NOT BROKEN, it scared me at first but I have had absolutely 0 problems riding this bike so far. I’m beyond happy with how it’s been performing. ——BIKE INSTEAD OF UBER! —— I was spending $15 on Uber rides 2 times a day, $600 to me is VERY WORTH THE PRICE if you are someone who takes Ubers to work or school and are looking to save money long-term. WARNING‼️ ‼️WEAR A HELMET, THIS THING IS FAST‼️ EDIT AFTER 1 MONTH: I love this bike. It’s made getting to work SO MUCH LESS OF A CHORE. GET SLIME FOR YOUR TIRES! I go over thorns frequently. I put slime in my tires and I no longer get flats.

I got this e-bike for my wife just over a year ago or 7. October 2024. Assembly was easy and bike was ready to ride in less than 30 minutes. Gears have never had to be adjusted but brake cables set in a little so after 2-3 rides I had to adjust the brakes. The weight of the bike is only about 45 pounds with the battery, so it is easy to fit on a bike rack and to hang to my wall mounts in the garage and it is easy to ride without battery power. Now after one year the battery is still like new and range is just over 30 miles running the bike at speed settings 2 or 3 (10 and 15MPH aprx). In august 2025 the bike stopped working. I contacted the Gotrax customer service and right away they sent a replacement display unit which was easy to replace. That did not fix the problem and right away and Gotrax sent a replacement controller unit and that took just over 2 weeks to arrive. Lydia at Gotrax customer service was very helpful and sent DIY videos how to replace parts. After reading few of the reviews I wanted to point out that when you buy an e-bike, or anything for that matter, from a small company you have to be self sufficient to DIY any repairs under warranty. Don’t expect a small business to have nation wide warranty repair service. I support small businesses and bike repairs are an easy DIY task especially when you have a video to follow. I do recommend this e-bike for anyone who needs a city e-bike or one to venture on the smoother bike trails. After one year of use and over 1000miles it is still running like new, battery at full capacity, tires good, gear shifting great and front suspension fork still smooth and its low weight makes it easy to handle. All of this at a very favorable price point.
