surf for VANCOUVER MYSTERY ELECTRIC SCOOTER -- the only scooter with video on Hollyburn Country Club, at the upper levels of Vancouver's mountainous North Shore. No "regular" 500W electric scooter can do this; not even the Ego-2 has gotten up this high.
Please surf for chain-drive ego electric scooter, also in EValbum.com
