Great bike. Good quality and easy to assemble. Battery life is good no issues. Just enough power to be in compliance with CA laws.

This product as well as Heybike Support make this an unbelievable E-Bike to buy in this price range. It's a very nice riding bike with front suspension and a spring loaded holding tube for the seat. The nice 20" by 4" tires give you the security you want to feel like so you can ride anywhere. Excellent system to remove the battery as well as a usb port to charge your phone while your resting. Here are some of the Pro's: 1: 8 different mode settings (Default 0-3). Can also set 1-3, 0-5, 1-5, 0-7, 1-7, 0-9, 1-9. Sounds like gibberish but you'll understand once you get one of these 2: Each of the settings you can adjust the power. Ex Mode 1=30%, 2=75%, 3=99% Why this is great. My wife and i both have E=Bikes and she has modes 0-3. I set mine to 1-5 so that my 1 goes 6 mph, my 2=her 1, my 3=her 2, my 4 is 4% faster than her 3 (so I can take breaks peddling) and my 5=her 3. So you can adjust your power for each mode so that you can peddle side by side with friends. 3. 500 watt motor with 48V 12.5AH motor. Power plus good lasting battery 4. Fold-able bike (yes it is 65lbs so a bit heavy but still doable) 5. Solid Frame and great front suspension 6. Fat tires (boy do I love them) 7. Easy to use throttle 8. Gear shifter that works like it's supposed. Marked 1-7 and unlike in the old days it means what it says. 9. Heybike Support. I wanted to make a slight change and I reached out to them. Not only to they respond right away, but they sent me a video to show me how to make the change. They also sent me a part from China which i got in about 6 days, so I rode my bike until the part came (no big deal). Also they sent it Fedex, and from China you know that wasn't cheap. Imagine a company that has a support group will to do this so that the bike is everything you want it to be. Cons: Heavy bike. So be sure if you going to fold it and place it in your car, remove the battery first. This will make it easier to handle. Even though I wrote this as a con. If you want a solid frame like this without spending $3000 to $4000 for a bike then this is the only draw back. For me it's not a con because I can mange the weight with no problem and I am 65 years old. One last comment. I wasn't given this bike to review or paid in anyway. I just believe that when a company makes a good product at great price for what it is, I always feel I should write a review. Especially with everything that the Heybike Support Group did to help me make this exactly what I want.

Great Bike! I purchased a Heybike Mars 2.5 years ago for my 19 year old God-daughter who used it as her primary transportation to and from school and work. Money well spent! I just purchased another Mars for me as I travel the country. It folds and fits perfectly in the backseat of my F-250 crew cab. Heads up... Even though I'm 6'3", 234lbs, this bike requires strength and focus. It's not a toy by any means. It can tip on you real quick... I love it..

My husband bought us the Mars bikes for Christmas and for my birthday road trip to state parks starting on the Dec 26. His black bike was fine but my white bike didn’t have the correct seat post. Needless to say we couldn’t use them for our special planned trip. Had difficulty contacting the manufacturer. Was told replacement post would not be available for them to send until at least 2 months but that we could purchase our own part from Amazon and they would refund. The replacement part wasn’t an exact match either and my husband had to heat and bend the metal seat lever to make it work but then had to repaint the part because heating the metal damages the paint. Just received notice that my Amazon account is being credited for the replacement part costs. We were able to take the bikes for a short ride and they seem to work fine. Didn’t get above 10 mph and my brakes needed to be adjusted. Learning to work the manual pedals and speed settings without the chain slipping. I will need to read up on the operation of ebikes to work out the correct way. Was able to foldup both bikes and fit into the back of my Honda pilot with the help of my husband but not sure if I could do it by myself without difficulty. I will probably purchase a bike rack instead. Overall I believe I’m going to enjoy the bike because the pedal assist worked wonderfully on mountain paths.

For being foldable it doesn't really shrink down much for it to be convenient to place in a trunk or backseat very easily. Can be a little heavy to tote around. Horrible handling in a rain storm at full throttle making sharp turns suddenly. Not great on ice. Very rugged and durable, I haven't had it completely die on me yet after 500 miles ridden and charging usually after every 15-25 miles or so. Longest trip on 1 charge has been 34 miles. Would not recommend changing any control settings in the computer that you aren't familiar with, I almost had mine stuck at 5 mph permanently just from trying to remove speed limiter. Brakes were great at 1st but seem worn down in front and need regular readjusting. Back cargo basket is poorly equipped with parts for fastening it to the cargo rack without it loosening enough to move a bit if carrying anything heavy and suddenly brake on an incline or decline. Withstood a sudden wreck going 20 mph full force into square island median curbed parking lot area, only ripped fender and headlight off and spun handlebars 360° with tires remaining unmoved. Only bumps and bruises and slight whiplash for me. I love this bike but I wouldn't marry it, I'd date it for 6 months to a year before upgrading to its hotter sister and pawning it off on a younger sibling and forgotten forever.

I don’t often leave reviews, but as I’ve been telling everyone in earshot what a great little bike this is, and good value, I am happy to do it here too. I ride this bike 5 miles to work on country roads, bumpy lanes and greenways, in all weathers and it is a smooth and fun ride. When I need to I can fold it and throw it in the back of my Jeep or Mini Cooper. Doing that, I broke the console, but Gloria from customer service helped me to replace it without fuss. Highly recommended!
