By Charles Pekow — A study in Holland found no differences in the severity of injuries of conventional and electronic bike users when taken to two trauma centers. As you might expect, eBikers tended to be older (average age about 67) than conventional bike riders (about 45). The study looked only at users aged 16 and up, including 78 electronic and 91 conventional bicyclists.
Conventional cyclists were twice as likely to have used alcohol, however. It certainly appeared to be a problem, since 40 percent of the former group had been drinking.
