I received my Turbowheel Lightning 5 days ago and have logged 70 + leisure miles on it. Initially, I was disappointed because the battery would not charge higher than 3 bars. Then I began going through the settings and realized I had the battery voltage set at 60v rather that 52v. Now my battery fully charges and no issue there. Then I was disappointed because the stem squeaked a lot while riding. Then I purchased a $4 tube of lithium grease and unclamped the stem. Then greased the heck out of all the parts that might have friction and the squeaking is gone. Everything works great. Single motor mood is cool and smooth. I was able to get to 26 mph on the straights and 12 mph up pretty steep hills. Now dual motor is a different animal. I am 6’-3” and I weight 235 lbs. I was able to get up to 36 mph on the straights and 25 mph up pretty steep hills. Dual motor is very powerful and a little jerky on initial take off, but I love it! I never felt unsafe at any speed. I would give the scooter a 10 out of 10 because it has now met all my expectations. Just remember to get some lithium grease for the stem and hold on tight when in dual motor mood because this thing pulls like crazy!!! I live in Washington DC and this scooter rocks thus far.
