This HiBoy S2/S2 Pro is awesome! S2 for me (I weigh 130lbs) and my husband got the S2 Pro (he weighs 235lbs). Wow, what a blast these electric scooters are! We took them on the bike path and traveled about 19 miles during our almost 2 hour scooting adventure! Mostly on comfort mode we synced our top speed for about 14MPH then the last 2 miles we zoomed around in Sport mode topping 18MPH! Sturdy and comfortable for a whole afternoon out.. such a great purchase and can’t wait to see where else the HiBoy S2/S2 Pro scooters will take us!
