Review on 🚴 CYCPLUS M1: Waterproof ANT+ Wireless GPS Bike Computer with LCD Display and Backlight - Perfect for Tracking Speed and Distance on Your Bicycle by Adam Martin

I like the design of this device. I think this is the best bike GPS you can find on the open market. The display is huge and I've never had any problems with glare. Unfortunately, this is a GPS bike computer and lacks accuracy. I went on a ride that I'm very familiar with and I know it's 25.6 miles, I ride it all the time. When I got back to where I started, the bike computer showed I had only covered 18.6 miles. That's a huge difference. I noticed that every time I drove through some forest area, the speed began to fluctuate wildly, sometimes it was apparent that I wasn't moving at all. It has a great design but is missing the most important part, the GPS part.
