I have recently purchased a Ridgeback electron plus ebike. The advertised range on an Eco setting is 125km which is about 77 miles. I appreciate that this is very dependent on the weight of the rider, the hilliness of the terrain, headwinds etc. However on a fully charged battery and all previous settings zeroed I am told that the Eco range is only 57 miles, twenty miles less than that advertised by Ridgeback. I have emailed them three times about this but they have not replied. So much for customer relations! I have also discussed the issue with my dealer but he does not know. Any advice regarding this issue will be most welcome as I am 71 and having an extra 20 miles on Eco is important for longer cycle runs.
