Exceeds My Expectations

I have been riding my Mars ebike since the first week of August 2023. Excellent customer service and excellent ebike durability (I have fallen a few times, no injuries), adequate torque, speed and wonderful PAS assist up steep mountain hills. Very comfortable to ride. Have traveled up to 28 miles (3hrs) up and down steep mountain roads on and off trails. I still have not been able to run out my battery. Ebike is great for my personal fitness making my rides as hard or easy as I prefer and also running my dog for miles alongside. At the same time providing a safe cargo basket for her to rest in during our remaining time outdoors. Very satisfied. Having a lot of healthy fun.

Charger Does Not Work

I received the Heybike and everything is great, however the charge does not work.


Gotten one of these over a year ago and ride it every day it ain't raining or freezing. I freaking love this thing ,it has a ton of torque u can stand next to this bike holding the handle bars and gun it on the throttle a lil and it will stand straight up with no help from me lol. Pretty crazy an electric motor with that much power goes for under a grand these days. PA my lil buddy loves it too. Lol my cat
