Gotrax Dolphin 26" Electric Bike, Max Range 30Miles(Pedal-assist1) & 20Mph Power by Peak 500W, 5 Pedal-Assist Levels & Front Suspension, 7-Speed&Boost Mode, City E-Bike for Adult, Step-Thru Bicycle

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.

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 am glad to have this electric bike. Assembly was straightforward, and I had it ready to room about half an hour. The build quality is solid, and everything feels well made and reliable. The ride itself is smooth, and it handles bumps and uneven roads comfortably. It is easy to adjust how much power I want while riding, and the speed system shifts smoothly. The bike feels stable, responsive, and easy to control.

I absolutely love the look, feel, and ride of this bike. I bought it because it was the lightest ebike I could find at this price point. I love that the battery is easily removable for indoor charging. The bike is sturdy and the handlebar and seet hieghts easily adjustable to allow others to ride. The pedals are strong grippy metal. I don't need to wear my bike shoes or add shoe cups as my feet stay firmly in place when peddling. I bought this bike because one of my favorite roots has significant hills in either direction. I love that this bike pedals with ease even with no power. I typically try to use the pedal assist mode only when needed to help me strengthen my biking muscles. Having the extra assist to get up, those hills is a dream. I did need to buy a new bike rack for towing as the bike does weigh about fifty pounds and is a step through model. I have taken the bike out on three good trips before having to recharge the battery. I would recommend the bike to anyone. Tip: my bike came with a light which I could not figure out how to turn on and then realized if you press and hold the up Button it turns on.

The bike is overall decent, especially for the price point. The battery life gets me about 16 miles before I need to charge it again. Which isn't too bad for using the assist. The Speed isn't too bad, I do max the speed out pretty easy so I wish the bike had a higher speed (This is an entry level so I'm wanting too much). It was easy to assemble and pretty easy to operate. The removable battery is a great addition because it means I don't have to find a random outlet to get my bike to. The charging time for the battery is quite longer than it was with previous bikes I had and the charger does get pretty hot when you charge it so make sure it is in a safe place. The customer service isn't the greatest, but lately they have been improving. They reached out to me about my previous issues and offered to completely replace the bike + cover the return shipping along with other things. Im grateful they reached out because the bike is pretty great overall for this price point.

This electric bike gave me a big surprise! It’s can almost pass for a mechanical one; its design is sleek, and its battery is integrated well into the frame. the battery is easily detached, and there’s a handle beneath the seat that makes it easy to move around. Speaking of the seat, it must be the shape or something, because i think it’s more comfortable than other bike seats i’ve tried. Aside from aesthetics and comfort, the electric bike has suitable range and speed if you want to go somewhere that’s a bit far by foot, but not far enough to justify driving. It’s got multiple speed modes, so you can toggle it to whatever feels comfortable. Overall, a good bike and great buy!

When it breaks, Gotrax will ghost you and you will have wasted nearly $600. DO NOT BUY THIS BIKE!!! This bike worked for us for about 6 months. Then it went dead and I emailed customer support. They started sending me parts to install. A new interface, a battery, a motor controller, a motor plug interface. Sometimes sent the wrong parts and we had to wait for another replacement. Every time they send a part it takes 2 weeks to get it. After 3 months and (I kid you not) 30 emails back and forth, I sent them a message (mind you still within the 1 year warranty period) that I think it's time for them to send me a new bike. That's when they stopped responding completely. My son missed the whole summer on his bike. Just know that when this thing fails you are on your own. You HAVE to go through Gotrax for help so that is your only recourse. What a piece of junk. 6 months of use and already a brick. Do not buy this piece of trash; get a better product!!

The GoTrax Dolphin is a great entry-level electric bike because most of its parts are universally available for replacement online and are super easy to learn how to repair on your own. I have had mine for over a year and have only had to replace the tires and innertubes once. This bike weighs under 60 pounds, making it very easy to pick up and take anywhere. This bike features a decent assist mode, allowing you to still get a good amount of exercise while enjoying the extra electric boost to easily reach speeds of 20 miles per hour. Best Cyber Monday deal ever.
