I Got this Trike because I love bike riding, but I am 48 yrs old now and have developed Osteoarthritis. Having the motor option is so very helpfull. I also have balance problems so 3 wheels is a good solution for me. I recieved this Trike yesterday. Putting it together was easy enough. It only took 4 hours. You will need some Allen wrenches, Channel Locks or adjustable wrench, and a medium size striaght Screwdriver. It is extremely comfortable, like sitting in a chair, and it's cool looking. I had a lot of people asking me questions about it while I was out. I took it out for my first all day road test today. This is where it comes a little short of 5 stars. I used the pedal assist all day, and at about the 14th mile the charge started to run down and peddaling became a little laborious. It is suppose to go 20 miles on a single charge.Twenty miles without labored peddaling would have given it 5 stars. Also there were no instructions on how to work the Odometer/Speedometer
