On bike electronics are for two things: safety and “don’t get lost”.

Safety

See and be seen is the motto.

• Rear DesignShine DS-500 flashing light (red, super bright)
• Rear Dinotte flashing light (red, very bright)
• Front Dinotte flashing light (amber, very bright)

This has a, one-button-push, get an ambulance here now function.

• Spot Gen3 Satellite Tracker

Also, I have created a “Find my bike” page using the Spot tracker on my blog.

To make sure I don’t over do it at the beginning of a long days ride I use the following sensors:

• Cadence Sensor
• Heartrate Monitor

Don’t Get Lost

Always have a paper route sheet in a plastic waterproof protector. Know how to use it.

For the route sheet you will need an odometer on your bike. I have two. One is very cheap, but has a battery that lasts at least a year. This is my backup. The other odometer is either the Garmin Edge 1000 or my iPhone.

I have been using a Garmin Edge 1000 for the last couple of years. I’m thinking of moving to the iPhone instead but I’ll need to test this on some long rides over the next couple of weeks.

• Cateye Odometer
• Garmin Edge 1000
• Apple iPhone 7 Plus
• Apple iWatch Gen2
• Battery USB Charger (extends the life of above)
