great starter bike budget friendly

great starter bike the seat may not be for everyone depending on the person ,also you have to pedal at least very slow to get the motor going if you stop pedaling it will stop too not automatic but still great on distance and speed great budget starter bike.

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
