Hi,
Just did this modification to my Giant Quick-E+ 2018 and increased speed from 32km/h to 45km/h. So cool, thanks for advice and video. Giant E-Bikes are advertised to go 45km/h or 28Mph, so my question is, is there any risk of damaging the engine or any other component of the bike by going faster? Thanks again, Gary from Cape Town South Africa.
