Only exercise I get!
I bought this to help me exercise, since I hardly walk at all. This bike forces me to pedal and I just love it. It was almost completely assembled in the box and within minutes I was riding it ( I should've waited to fully charge the battery, but it had an 80% charge so I went for it ). With the large tires and shocks the rides smooth and when pedaling in high speed it moves pretty good! Tons of fun for young and old… I wish I got a larger bike (26” wheels) because I'm 5'10” and the larger bike would be more comfortable for me, but I'm really happy with this one and it's very comfortable to ride. I added lights so I can ride at night and it's a blast! The compartment under the seat holds everything I need plus a bottle of water.

So much fun!
We are having a great time with this bike! I was hoping it would fit my grandson who is about 4'6”, but he needs to do just a little more growing. My daughter in law and I are loving it although it's a little short for her. I'm 5'4” and it's perfect for me. This is our 2nd Hyper brand bike and we are very pleased with the quality and design. This bike is a perfect way for older people to get back into cycling. It's so easy and fun!

its awesome
I love it, yes, its a bycicle. If you expect more well, your dumb. the fastest you can go with the fastest option is 18mph. You do have to be pedaling it but i like it that way. its assisting you as you go so it doesnt accelerate its self. Its got big wheels, perfect for offroad and everything really 10/10 would recommend
