The catch with each
E Ride Pro SS 4.0: At 161 lbs it is a solid step up from the 125 lb Light Bee class, and the seat height isn't on the page we read: sit on one or ask before you buy if you are short. It's an off-road and closed-course bike, full stop.
Talaria Sting R MX4: The dealer says it ships limited to 20 mph to comply with federal, state and local laws, and asks buyers not to bypass it. And it was shown as unavailable at REV Rides on November 12.
