This is a solid, comfortable riding bike. Power is great, and it's a smooth ride. The bike arrived carefully packaged in a crate and is fairly easy to assemble on your own if you follow the enclosed directions (but just know it does take a few hours if you're not familiar with this kind of assembly). So far, I've been impressed with HappyRun's customer service. Every time I've emailed support, I've received a response within 1 business day. We had an issue with the battery overheating within 2 weeks of purchase while riding in 60 degree weather. I emailed customer service, and they immediately sent a replacement battery. I've emailed customer service twice since then to request parts that were damaged through accidental spills (not because of defects with the bike) and I received those parts quickly as well. We'll be keeping an eye on the replacement battery, as it tends to run hot, even in cool weather. There are also two features that prospective buyers need to know about: 1. There is no quick release cord, so it's a time consuming and tedious process to replace a tire or the battery. This choice may have been due to the fact that it's a dirt bike. We figured out what to do using YouTube videos and ordering special tools on Amazon. 2. The leather-like throttle grips that our bike came with looked sharp out of the box, but they immediately started showing wear after just a few days of use. I understand that there's now a rubberized version, so, if you have the option, go with that because they'll be much more durable. We've had this bike for a little over three months now and are pleased with it. It's been a learning curve because we've never had an Ebike or dirt bike before, but, given the option, I would purchase this bike again.

Bike was great until is stopped working after 30 miles. Chatted with customer service and they were fantastic. Have the parts on the way and hoping it has more power with a new controller. Didn't feel right from the beginning but because they stand by there product it will hopefully soon be fixed.

I bought this bike for our son and he absolutely loves it. The quality is excellent and it runs really smoothly. It feels sturdy and well built, and we haven’t had any issues with it so far. The customer service has also been fantastic, very responsive and helpful when we had questions. Overall we’re really happy with this purchase and would definitely recommend it to friends and family!

This bike is so fun they should have named the company HappyFun! I wanted to give a in depth review about the things I was concerned about with this bike. It's a long review but in short, I am impressed! The suspension is solid and the adjustments function properly with rebound rate and stiffness on the front and back, just like a motorcycle. Stiffness and rebound rate can be adjusted with a screwdriver on the forks, while the rear mono shock can be adjusted for rate with a screwdriver, and for stiffness by turning the collar with a special tool which will compress the spring to make it more stiff. It came adjusted 3/4 stiffness which is good for my 145 lbs weight. I have jumped this bike and the suspension has not bottomed out yet. The assembly was easy and took about 1 hour. The range is good. I rode it aggressively on the pavement and on dirt trails and still got 45 miles off a full charge. If you ride it conservatively you could probably get 60 or more miles. The customer service is top notch with HappyRun. I had 2 parts that were damaged during shipment and they responded quickly and sent the replacement parts free of charge. This bike is in a class of it's own. You won't find another bike with this power that you can putt along peddling like a bicycle, and then rip it up with high voltage power on the trails. The direct drive motor is silent which adds to the covert nature while providing a top speed of 48 to 50+ mph depending on rider weight. Overall the quality is good. The welds are solid and it has held up to some very hard trail rides with jumps, rocks, roots and small logs. I have about 100 miles on it so far with most of that on dirt trails and no broken parts so far. I highly recommend buying this bike.

I’m not sure if rating it three stars is being a bit more generous, the packaging precautions they took is not the best at all. Some areas they did good but a lot of the other areas they left a lot of the bike exposed. The box was damaged when I received it which was concerning so I took pictures and documented it and contacted them. They responded fairly quick but when given the documentation of the damaged parts and issues that I had with the bike they seem to be a little stingy on help resolve the issues. Assembly process was decently lengthy as well which isn’t really an issue. The weight of the bike is a lot heavier than most other bikes. Depends on how you look at it with it being a lot more durable feeling in my opinion. I got the bundle with the bike, bike lock, and phone mount but I did not get the phone mount with it, on received the bike lock. Also when triple checking the connections and having a fully charged battery when hitting some bumps the bike seems to turn off like a safety feature is enabling from a false positive? I would suggest buying your own blue thread lock for the handlebar screws because no matter how much you tighten them they seem to come loose. Acceleration is pretty weak to be honest as well which I assume with it being a rear motor. Out of the box default settings are pretty good, allows you to change up to the max mode to eventually hit that 50mph speed but definitely takes some time. Bike is actually pretty stable while going the max speed as well it doesn’t wobble which is surprising. Suspension is pretty good as well even though I was dealing with it squeaking a lot until I had to add grease to it myself to get rid of the noise. Battery life seems as advertised as well which is nice. Appearance of the bike is pretty slick definitely will catch some attention. It’s a fun bike for the price and power but definitely a lot of areas they could have improved in. I’m 6”2 as well and with the bike being decently higher up it’s nice and comfy for me since I don’t have to bend my legs a lot. For the price point though I feel like the consumer shouldn’t have to do so many troubleshooting to get the bike to a comfortable spot to ride.

I bought this bike for my son. It seems very durable and well built. Unfortunately it did start showing an error code 30. I contacted the company by email and received a response with suggestions on how to clear the error in less than 12hrs. Unfortunately we could not clear the error. I contacted them back and in less than 8hrs they responded informing me they were spending new report parts. I received tracking info very quickly. The bike of solid. Customer service is excellent and very quick to respond. I’m not sure what caused the error but the repair parts arrive today. I’m sure even of these parts don’t fix the problem this company will make it right. I would absolutely buy from them again and recommend them
