Beautiful bike, butt.

Everything is wonderful on the bike, 'butt' the seat stem shock absorber is not smooth. It's steps rather than being seamless up and down motion.

Jason Cortes
A Game-Changer for Heavyweights!

I stand tall at 6'1" and weigh 400lbs, and let me tell you, the Heybike Mars has blown away all my concerns about being too heavy for an ebike! This marvel effortlessly propels me to 20 mph, tackling hills and off-road terrain without breaking a sweat. What's more, I didn't have to break the bank with a $2,000+ bike. The Heybike Mars takes me on a battery-powered adventure that shows no signs of slowing down. The seat? Pure comfort. The ride? Incredibly smooth. To my fellow heavyweights, I wholeheartedly recommend the Heybike Mars – it's a ride like no other!

Mike Muttart
Fun Bike

This bike is very fun and seems well constructed, but time will tell. There was more assembly than I expected as the front wheel had to be put on and that led to issues with the disk break rubbing (in the videos I saw before purchase the front wheel was already attached when delivered). Also, the display is quite small and difficult to see with sunglasses on (the display in the videos was of a different type and appears larger). Finally, I wish there was a way to unlock the speed to get 25 mph (I easily get 20, but 25 would be nice). The bike is a blast to ride, it's a nice blue color, and I'm overall very satisfied with my purchase.

Mars first 20 miles

Wry impress with the bike. Shifts great and rides smooth. I have not yet transported it folded. I use a rear rack. Brakes are good and seems to hold a good charge. Definitely will be buying a bigger seat though
