Just got my Swagboard Voyager today. Took it out for a spin near my neighborhood basketball court Super fun board. Very smooth ride and the dual hub motors are super quiet. It went pretty fast at only 10 mph. I was too scared to go the full 15 mph. Still trying to get use to the board and the speed/braking.
Braking is a little sketchy and sensitive. According to the manual, you have to lightly decelerate using the trigger. The remote control has additional buttons to accelerate/decelerate. Much easier to use than the trigger. Board is kinda BIG and heavy due to the larger battery. I guess that is a good tradeoff if you want a longer ride. I think the board is sporting 90 mm wheels which works great in going over bumps.
