Nice to see both brakes on the handle bar. I like to keep my feet planted if they have nothing to do. I guess I got the habit from driving scooters. On the other hand, if they build that design, they need to rethink the final drive layout. With two idler pulleys (on the cog side of the belt no less) that are reducing the wrap in the front pulley, they will shred the drive belt the first time someone hammers the throttle. There appears to be little reduction ratio based on pulley size in the final drive. That puts a lot of torque on the system and the belt.
