The direct cable connection of the speedometer to the transmitter ensures smooth speed measurement. A battery for wireless transmission is unnecessary with the R1 WR, allowing your bike computer to operate for years without the need to worry about battery replacement. The display of the R1 offers ample space at 27 x 35 mm to continuously show your current speed and clearly present other important functions. The display is kept simple: with four different symbols, it is always clear which function is selected in the bottom row. The icons make the bike computer extremely easy to read. It’s hard to get quicker on the bike: with the cable ties, you can securely attach the handlebar mount for the R1 WR and the speed transmitter. The bike computer is always easy to remove and store. It couldn’t be simpler: the R1 can be safely operated even while riding, thanks to its large button. This allows you to easily switch between the various functions. Combined with the larger display, the ergonomics are taken to a new level. No matter the weather - the R1 delivers. It is waterproof and weather-resistant, making it reliably usable in everyday situations. Thanks to the predefined tire sizes, setting up the R1 is effortless - from a small children's bike to a 29" bike. It is also possible to enter the tire circumference with millimeter precision.
