Ride Test Dummy
These fabric-based water dummies provide the most flexibility in providing ballast to your ride. They have a fill port in the head and a drain port in the leg. They include strap handles on the sides for easy handling.
Without water, each dummy weighs a mere 1.3 kg (2.9 lb) and only takes up the space of a shoebox when folded.
The dummies weigh 90 kg (198 lb) when fully loaded with water.
For loaded dynamic ride testing per ASTM F2291, the ballast for each seat is to be 170 lb (77 kg).
