Geez.... I need a bike to travel long distance, I have to travel from Tseung kwan O to Tai Po and back (60km) and sometimes will go through Sai Kung(68km) to save tunnel fees, this won't work for me, especially that massive battery pack, not worth the hassle, will need to install a rear storage box as well for my grocery shopping, adding that, I assume it will reduce the mileage even more due to the weight.
