Impressive commuter off-road and folding bike.
Color: Navy Blue
Great Bike, easy to assemble. Folding is surprisingly super helpful for a fat tire bike. Was able to fit into my Camry trunk. You might want to buy a backup light but that's about it. Great battery, speed, and suspension.

A Ton of Fun — Especially for Bigger Riders! ⭐⭐⭐⭐⭐
Color: Sunset Orange
I am extremely happy with my purchase of the Heybike Mars 3.0. Honestly, it’s one of the most fun things I’ve purchased in the past few years! I’m 6'4" and 260 pounds, and this bike feels like it was made with larger riders in mind. It has plenty of power, and with me riding it, I’ve reached a top speed of around 28 mph. It has multiple riding modes, ranging from Eco up to Sport, so you can choose how much power you want. You can ride using the throttle, pedal assist, or a combination of both. I’ve really enjoyed having the flexibility to switch between them depending on what kind of ride I’m looking for. The battery has also impressed me. I got at least 35 miles out of it on one ride, and I probably could have gotten even more range if I had used more pedal assist instead of relying as heavily on the motor. Overall, I’m giving the Heybike Mars 3.0 five stars. I absolutely love this bike! It has made riding a bike fun for me again, and I actually look forward to getting out and riding it. Great bike, plenty of power, good range, and a whole lot of fun!

Great value, very solidly built, there's even a phone app.
Color: Sunset Orange
Bought the Mars 3.0 to use this summer and so far my wife and I love it! However I'm use to riding my hard tail, this ebike makes getting around so much more enjoyable. IMHO it handles great, I love how the different modes actually make sense when it comes to pedal assist, and my wife and I both agree the orange looks great. Everything was in order in the box, assembly wasn't bad at all, very satisfied with the bang for the buck here. We have our 3 yo in a Bellelli Pepe rack mount seat attached to the back, during family rides and it goes on and off the back rack like it was made for the bike. Lastly, I'm more than happy with it's strong braking.

Arrived missing parts and defective breaks. Seller resolved issue.
When delivered the one box appeared to have already been opened at one time. That bike was missing covers that went over the front wheel nuts. No big deal. The big deal is the second bikes rear breaks don not work and looks like I will has to take to a bike shop to have them repaired. NOT HAPPY !!!!!!! 2026.01.09 Review Update. The seller was very understanding and worked with me to get the bike fixed and paid for the repair. We are now enjoying our new Heybikes.

The best Foldable Bike
Color: Onyx Black
The bike is exceptionally comfortable, and I’m a big fan of both its sleek design and its smart features—especially the ability to power it on remotely via the app. Furthermore, the high-quality suspension system does an excellent job of absorbing bumps, making for a much smoother and more controlled ride.
