    • This bike was worth it
Review Image by Andrew Cross
First off I bought this bike for $375 so I was skeptical if it was going to even work. When it arrived I put it together which was very easy, I charged the battery, and it was ready to use. I love the fat tires and how the bike can accelerate up to 30mph roughly. I am 6’ tall 160 pounds and it is very comfortable. The only complaint I have is the battery life. I use the throttle a lot so I am sure that drains the heck out of it but I can go maybe 20 miles and it will be 13%. Like I said, I use the throttle a lot because its fun and convenient so I am sure that drains it much faster. It takes 6-8 hours to fully charge the battery. Other than that, I love this bike. Ive gone almost 200 miles on it so far. My only recommendation to a buyer is to tighten all the bolts and then check them after the first few rides. My front wheel almost fell off but that is because I was having so much fun that I wasn’t considering the bike maintenance. Pros, big tires, fast acceleration, and easy setup. Cons, the battery life could be improved but it is not terrible. I really have no other complaints. This thing rips ... show more

    • Broken down quickly
Nice bike but the controller went down after only a handful of rides. They sent the wrong one to fix it, which was a nice gesture, but we basically bought this bike and it’s been a garage ornament. Maybe we got a lemon but still trying to resolve the issue with the seller. I wouldn’t buy this bike again. ... show more

    • Powerful Bike
I have had this bicycle for a 3 weeks and have been enjoying it very much. It has a lot of power for climbing hills on our property. The battery has a lot of power and lasts a long time. It's faster than advertised. The grandkids sit on the front of the seat and hold on to the handlebars and get to go for rides. The brakes are excellent and have very good stopping power. 3 days ago I purchased a second one. ... show more

    • Cheaply made
We purchased this for our teenage son to be able to get to work until he got his driver's license. The issues we have had this far: front forks bent from minor impact. This happened twice, once with the original field and once with the replacement forks. Flat tire, while this is not unusual, we realized the cheap tire that came with the bike. It was very thin and flimsy. When we replaced the tube the original tire wouldn't seal on to the rim, so we have to replace the tire also. When our son had to push the bike home with the flat the tire rubbed against the brake line and caused a fluid leak from the line. And lastly, the battery lasts about 20-25 miles on normal roads, no major hills, just the natural ups and downs. In the description of the bike they don't really say actual miles. ... show more
