A: It’s all waterproof but def not going to hold up if fully submerged. I’d worry more about the gears and other mechanical parts rusting if it consistently was downpoured on. I’ve ridden in the rain a few times and had no issues if that helps. I believe these tires would eat through snow with ease; however, salt on the roads from plows will definitely kick up on the bike so I’d for sure clean it after each use and get some kind of thermal cover for the battery if it will be exposed to extreme cold for long periods unused
Q: What is the maximum operating range mean? What does it effect on this bike?
A: It means on no pedal assist it can go that far between charges but higher the pedal assist lvl the more battery it uses cause you go faster and if you have it all the way up you can go like 28 mph for 8 miles plus with no issues
A: One year
Q: What are the dimensions of the rear rack?
A: 6.75” x 15”
Q: ARE THEY ASSEMBLED WHEN YOU PICK THEM UP?
A: You will have to install the front tire, rear rack and handle bars. It's pretty simple and doesn't take long.
Q: Is the battery detachable to take in the house to charge ?
A: undefined
Q: what tools do i need to put this together?
A: It comes with all tools needed, but it will be a lot easier with a ratchet set.

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.

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..

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.
