I've been riding scooters for several years and the TurboWheel Lighting+ is HANDS DOWN the best bang for the buck, especially for top speed and torque. All the specs listed by eWheels are correct...range and speed (I'm 150 lbs for reference)...and considering this gets to 40-4 mph, and gets you there with amazing torque, this is NOT for first time riders. (although I mildly workout, for the first week I was wondering why my arms, forearms, and pecs have been sore...because of holding on when taking off in dual mode. What's the complete opposite of buyers remorse?....whatever it is, I've got it...only regret is why I didn't get it earlier. ...and customer service is excellent...Jason at eWheels has been there answering every question, and fast. ...there nothing better than to pull up to a street light (bike lane portion) in full helmet, gloves, etc...and get looked at by a hot rod drivers, and see snickers and rolling eyes, only to lean forward and hit full throttle when the light turns green and leave them in the dust, to the speed limit of course. Jason, you should send me a stack of your business cards, because I'm asked about the Lightning+ at over half the stop lights I'm at here in Houston. Thanks for selling a great product! - Tre'
