Just picked up this Nanrobot D6+ from Roadruner Scooters. Awesome machine and great company to work with. This is just my opnion of the Scooter and its functionality. All in all I am very pleased with the Scooter and have no regrets whatsoever. Truly I believe this Scooter is all I will ever need. I don't see any reason to upgrade at all. I don't need to go faster than 42mph......... Comfort is on point, power, battery, neck, deck size, suspension is great! I hope this gives some information to help you make a decision on what Scooter to purchase. Don't do what I did! I bought one, not enough, bought a better one, broke the neck on it jumping, then got this one and it is my end all be all Scooter. Thanks for watching!!
