Review on Hiboy S2 Electric Scooter - 8.5" Solid Tires - Up To 17 Miles Long-Range & 19 MPH Portable Folding Commuting Scooter For Adults With Double Braking System And App (Optional Seat) by Jim Plump

I won't say 5 stars means it's the best EV scooter out there, but it is exactly what we wanted for our 12 year old son. We bought him a Razor EV scooter rated for 12mph and that thing barely could move him (130lbs) up a 5 degree slope.So we returned the Razor and purchased the Hiboy S2. It was on sale but slightly higher than the price advertised today. We chose the S2 because it came with solid non-inflatable tires, 19mph, 17 mile range.It has enough power and torque to drive up a 20 degree inclined street with a bit of degradation at the top of the hill. Coming down the same hill we cn mx out at 23 mph. On flat surfaces it does reach 19 mph.Battery life is quite good. Don't know exact miles per charge but it does hold the charge over 40 minutes of riding. At constant 19 mph, it should take you about 53 minutes to reach 17 miles max range.It recharges without any issue so far. Hope to keep the battery life healthy by charging it once month during the winter season.There are two speeds built in the app where you can set max speed to 13 mph or 19 mph. For the first week my snows riding around set to 13 mph. Once he got used to the scooter he rode it at full 19 mph. It also has electric braking which I think helps to recharge the battery - like in F1 cars. He has to kick start the scooter for it to start moving. The throttle won't engage unless the scooter starts moving. This feature prevents it from starting suddenly from a full stop.Build quality is excellent. When compared to the Gotrax scooters, the main steering tube is smaller in diameter than the Gotrax, and the deck is much thicker then Gotrax. Gotrax houses the batteries in the steering tube while the Hiboy is under the deck. The Gotrax looks more streamed lined but both equally built well.So far the solid tires have been holding up but showing some wear. We may have to get new tires sometime mid season next year.We bough this Hiboy because my 12 year old is 130lbs and 5'2". Any other kids EV scooter would not be ideal for him. Note that the steering tube is taller on the adult S2 than kids size. I would not recommend for kids under 5 ft tall. Always wear a helmet.
