Well, I am very happy with this bike. I purchased a hay bike Mars about a year and a half ago. The battery always gave me range anxiety and it failed just about a year and a half old and I was always having to cut my trip short because the 10.5 amp battery was never sufficient. I could never get more than about 22 miles of range, so then I figured I would try this bike which I have been very happy with. I’ve already have about 300 miles on it less than a month. It is simply incredible bike. It will go up grades that are almost impossible for a motorcycle to climb. The all wheel drive is incredible. It helps you achieve speeds very fast and no matter how steep the hill is you’re not gonna go up that hill under 20 mph even with a 250 pound passenger I’ve been on this bike that my other bike would totally stop and not go up the hill And I’ve done it at 20 mph on this bike. Overall, I did a trip the other day that was 60 miles on the odometer about as fast as I could drive the bike which is usually around 32 mph and coming down the hills at about 38 mph and I did really hilly situation and I still had over 20% battery left after a marathon run with both motors going about as fast as I could possibly go so I would say it probably has about a 75 mile range at the absolute minimum. I think it’s going to have well over a 100 mile range with flat land for sure. I never get range anxiety at all this bike will wear you out before you can wear the battery out. . The speedometer is very accurate. The headlight is super bright at night time. The tail light is not really that bright, but I added a super bright 400 candle power flashing rechargeable light to the back for only $60 That you can see probably a mile away but overall I have Had no issues it was very easy to put together. It was very easy for me to adjust the disc brakes so that I had no drag. The brakes are awesome coming down literally 30% grade. They have no problems whatsoever Super powerful hydraulic brakes basically everything that the hay bike was not. You can take the battery and the seat out and pretty easily put it in the trunk of most any car. The only thing I did notice at full speed I did get a little bit of vibration out of the front motor for some reason, but if you level off just a little bit, it goes away, but this thing is a champ soft dirt. It’s like a motorcycle upgrades that you could not hardly even walk up overall I’m very satisfied. Also, the battery being so big it never feels like you’re working the battery out hard at all and even with that 60 mile mountain ride the front motor and the rear motor does not even generate any heat. I don’t understand that it runs very cool unlike my other bike that gets very hot, so hot you can’t even touch the motor on the Hay bike. I don’t know what the difference is, but they didn’t want to take care of a battery That went bad just a few days out of warranty so that’s why I decided to go with this bike and I’m very happy and I think you will be too. It seems like my wife uses the bike more than I do and she loves it and she’s only 135 pounds 5‘5“ and she can handle the bike with no problem at all. She does want me to get her one of them that has the step through frame. I am a charter bus driver so when I get to a destination, I love to explore the entire city all day long and go pretty much anywhere and this one will do it with no problem whatsoever I don’t ever have to turn around and come back because I’m scared the battery will not make it back home. Very good quality and great value I would recommend this bike to anybody. Thanks, Limomike
