8 ESSENTIAL FUNCTIONS w/ SPEED COMPARISON AND MULTI-DAY TOUR TRACKING: On a weekend bike trip with the family or commuting to work, the BC 8.0 WR features the eight essential functions: trip distance, speed, total distance, trip time, clock, total trip time, average speed, and average speed comparison. The BC 8.0 WR measures trip time and distance for even long bike trips. This makes it convenient to read the entire distance of a multi-day biking holiday.
CONTINUOUS SPEED COMPARISON: A special feature of the BC 8.0 WR is its continuous comparison between current and average speeds. It is displayed with an arrow: If the arrow is pointing up, the cyclist is faster than their average. If it is pointing down, they are slower. At approximately average speed, no arrow is displayed.
STABLE DATA TRANSFER & PREDEFINED TIRE SIZES: The computer's direct cable connection with the transmitter ensures smooth speed measurement and eliminates the need for batteries in wireless transmission. The wired reed sensor with its sleek, slim design is easy to mount on the bike. The pre-defined tire sizes, ranging from a small child's bike to a 29" bike, make it easy to set the BC 8.0 WR. You can also enter the tire circumference exactly to the millimeter.
EASY OPERATION & SIMPLE MOUNTING: The BC 8.0 WR's 31 x 39 mm display is just the right size to give cyclists a perfect overview of data. Its large numbers make it easy to read, even during a ride. Handlebar bracket can be mounted on the bike with the cable ties included in delivery. Setting and using the BC 8.0 WR is very easy – and requires just one button. You can toggle through the functions safely and easily at any time. Display can be in English, German, French, Italian, Spanish, Dutch, or Polish.
WEATHERPROOF w/ LONG BATTERY LIFE: The BC 8.0 WR is water-resistant and weatherproof, so it can be used at any time. Cyclists do not have to worry about the wired speedometer's battery life either. The integrated, replaceable button battery (CR 2032) is sufficient to supply the BC 8.0 WR with energy for well over two years.
