In this study, we looked at the effectiveness of a new rear anti-tip device (the Arc-RAD, so-named because it deploys through an arc) as a spotting tool during wheelie training, testing the hypothesis that participants trained with the Arc-RAD would require fewer spotter interventions then those trained conventionally. Fifty-nine able-bodied participants were assigned to the Arc-RAD (n = 24) or spotter-strap (n = 35) groups and underwent training of up to 3 hours. All participants in the Arc-RAD group needed 0 spotter-strap interventions while those in the spotter-strap group needed a mean (±SD) of 13.8 (±12.1) interventions (median 9.0) (p <0.0001). The Arc-RAD group had a mean of 36.4 (±35.7) Arc-RAD loadings (median 21.5), a significantly higher number than the spotter-strap interventions of the spotter-strap group (p = 0.0028). The Arc-RAD appears to be a safe and effective spotting tool for wheelie training, a finding with implications for training practices.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
