Took the bike out for a spin and it worked great. The power assist helped when going up steep grades or even shallow ones. Limited space on handlebars for accessories like a rearview mirror or horn. I am 78 years old and the shortcomings for me were the small seat, low handlebars, and some difficulty mounting the bike. Was able to purchase a kit to raise the handlebars and install a larger seat. For older people with some hip issues, getting on and off the bike can be difficult. Overall, the bike performs as advertised. Doing 20 mph was easy. Maximum range for me to date has been 10 miles total. Battery recharges in a reasonably short time. I also purchased a second bike for my 16 year old grandson. He has zero difficulty with it.
