Surprisingly Powerful Mountain Bike.

Pretty powerful mountain bike, the price is great and also it looks very nice in black color. Like moped style. Seat is super comfy. Take off is abrupt, be careful. Battery gets you far on one charge and I am very pleased with this mountain bike! Assembly was easy and straightforward and it didn't take much effort to get it ready to ride. This bike feels sturdy, well-built, heavy and reliable. It rides smoothly and has plenty of speed for an enjoyable ride without being too much. The brakes and suspension are great and work very well. I rode it for almost 60 miles yet and I don't see any loose bolt. Its 750W motor is strong enough, I highly recommend wearing a helmet and be very careful when you ride such a powerful mountain bike. I use it daily. Great value for the money!

Ebike

This e-bike is perfect for my 12 year old boys. My only complaint would be that some of the assembly was more difficult that it need to be. They give you all the tools need for assembly and it comes with a tire pump. If not for one or two over tighend bolts id give it 5 starrs
