How does it work?

The track you’re racing on has a MYLAPS system installed at the start and finish line and at intermediate points along the track. The system picks up the signal sent out by the transponder mounted on your bike. This signal is analyzed and lap times measured. The system knows exactly on which lap you are and what your position is. This data is passed on to race officials and is published to your personal MYLAPS account on mylaps.com.

*Ask your club or race organization if they support MYLAPS transponders.

Your personal data

When the MYLAPS system is in practice mode, you can use your transponder at training sessions: all of your laps will be measured and automatically uploaded to mylaps.com. You can create a personal MYLAPS account on mylaps.com that provides you with free and unlimited access to all your performance data.

When used at events, the system measures lap times and determines finishing positions. This data is passed on to race officials and published to your personal account, where you can analyze and share your results. Insight into your results will help you improve your performance.

Easy to set up and maintain
Position the transponder at a maximum height of 120 cm (4 ft) above the ground. Temperature range: 0 – 50 °C (32 – 122 °F). Operating time is 5 days. It takes about 16 hours for a full charge. Keep track of battery status with FLEX Manager, available as a free download for Windows. The transponder is dirt and shockproof and easily cleaned with a damp cloth or brush. Use a cotton tip to carefully clean the connector pins.

Insurance and warranty
Your subscription comes with insurance. It covers damage as a result of accident or fire – but not theft or loss. This means MYLAPS will guarantee the device keeps working and is in good order. We provide an unlimited guarantee for the duration of your subscription. Should any problems occur during normal use – as described in the manual – MYLAPS will repair or replace your transponder free of charge.
