Our test Robot, Crank Armstrong Using Crank Armstrong, Kurt Engineers can break a competitive fluid trainer in several hours. Feedback from bike dealers confirmed that leaking fluid units are a major issue with " other" trainers. Below is a picture of Crank Armstrong, the newest member of the Kurt Testing Team. Crank is powered by a Dayton 3 HP electric motor, driving through a Boston 10 to 1 gear reducer, and connected to the non-chaining side of the bicycle bottom bracket. In this photo, Crank has a 207-pound "rider" and running at 25 MPH, adding mileage to the test resistance unit and checking the durability of our custom feet. After 96 hours of continuous riding (2297 miles), neither unit nor feet (or Crank) showed any signs of wear.
