    Overall great bike

    This bike performs well. Goes up hills with ease. Plenty of torque. The display is pretty nice. I have put almost 200 miles on it in the past week and a half since I bought it. Every time I'm out someone stops me to ask about it. The assembly was pretty easy and didn't take long. Overall it's a great bike. The brakes are good enough for me but most people think they are a little weak. The brakes were out of adjustment out of the box. I had to YouTube how to adjust them. They were rubbing and making allot of noise when not even using them. They are a little noisy when using which will make people turn there head. The seat is pretty uncomfortable. You will probably want to replace it. It will probably be my first upgrade. I average about 22 miles per charge. That is mostly using throttle so don't expect anything close to the advertised because it is a pretty small battery. I would like a second one but they are sold out. Hopefully they will have batteries again. This bike is a lot of fun. I use it on almost a daily basis.

    Excellent bike, no regrets!

    I didnt know an ebike could be so much fun! I ride just to ride because its so thereaputic. Speed is 28mph, I messed with the settings and was able to unlock 31mph. That is plenty fast. Going uphill is easy for me at 170lbs. Depending on the incline it will top out around 10 to 15 mph. Pedal assist definitely helps going uphill also i advise you use it to save your motor. Headlight is bright amd horn is ok. Brake lights are a huge plus. The cons .... Brakes are not very good. You will stop but you need ample time to do so. They are also squeaky. The other con is the seat is not that comfortable. After an hour ride you feel it forsure but you can always get a more comfortable one. Overall i love this bike and will be buying another.

    It’s really fast

    I cannot express in words how much I love this bike. First, the breaks aren’t great. Second this bike is great anyway. Great speed, good range, the stock seat is comfortable, it is not too bad to put together. But I just can’t ride this bike enough. The shocks are great for city riders smoothing out curbs and potholes. I have 400 miles on mine and it seems to be holding up fine. I would definitely recommend this bike and I would buy this bike again.

    Amazed at this thing!!

    I was hesitant but but I couldnt be happier with my bike. I get 30 miles at 24mph in throttle only mode and it doesnt matter what terrain you ride on. It tops out at 29.5mph. The brakes and gears are on the cheaper end but I knew this beforehand The motor however is powerful enough for whatever. I want to buy another for my son so we can ride the trails together. Such a blast. Just keep it slow at first because there is a little learning curve. The peddle assist will throw you forward when you dont want it to so make sure you are in 0 when you stop at crosswalks or any other danger area. I have discovered so much that I wouldnt have ever seen if it wasnt for the HeyBike..

    Love this bike!! I want to get a few more Heybikes

    Absolutely love this thing. Ships with throttle restricted to 20mph. Can be adjusted in settings to hit around 28 in pedal assist. Wish the brakes were hydraulic at those speeds. Shipping was two days and no damage; however rear tire had lower tire pressure than the front did. No leaks in it and I found the ride actually a little more comfortable lowering it some in the rear. Double check the spacing on the brake pads in the calipers. Mine were both running a little but was a quick adjustment. Battery will drain after like 2 hours of riding at max speed; however, I like pedal assist 2 mode(13-15ish) it’ll make it almost the whole 48. I suggest a bag for the rack. I keep bungees in it. Use the bike often to run to the store to grab small items and to the gas station to get a bundle of firewood to bungee down to the rack. Works fine. I’ve bungees fishing poles and gear to it and road right along the river fishing. The off road is amazing. Definitely purchase a handlebar bike mirror for the left side if you are in the US. I got a meachow brand that folds so when I bring it in for the night or lock it next to other bikes it’s not dinging around. I really wish I would have purchased two. I just hit the 250 mile mark on the odometer and have barely had it a month and a half. It is a lot bigger in person. I’m 5’8” and just barely raised the seat so I can get the suspension feel in the ride and I can hardly reach the ground full vertical. Folding is fun but it’s so heavy (90lbs) I don’t bother much easier to use the handle to lift it while it’s not folded.
