sprockets are custom made for the Whike. To maintain safe and responsive stopping the trike is fitted with
disk brakes on all wheels. The cycle also has a handbrake function to prevent it sailing away while without rider. The frame is available in black or white chromium molybdenum alloy steel, other colours are possible for an additional €100. The Whike weighs 23
kgs including the sail and can carry a maximum weight of 115
kgs including luggage. The sail also has the advantage of aiding visibility of the cycle on the roads.
