Two ten week trials of electric bikes in Australia have resulted in a 50% uptake, with users reporting savings of around $530 over the hire.
 Sixty people in Perth and Albany were granted use of e-bikes in a study conducted by the RAC, the first run in 2015 and the latter late in 2016. Post-trial surveys have since returned some startling results, including news that around half have since purchased their own electric bike.
 Almost half of work trips completed by electric bike in the Albany trial, starting at a 60% peak in the first week and sustaining to 28% by week nine of the trial. (Time of year not weather indication were not cited). The majority suggested at the end of trials that they would be recommending electric bikes to friends and family.
