New Rider 420

Moved up from the Rider 330, love the larger screen and additional functions

Bryton 420

Nice excellent bike computer. Not a touch screen. The buttons in the back are little confusing during a busy ride. The speed/cadence sensors makes the data more accurate. I like the page custom settings. Cute feature where you can set the alert limits. Which I set the speed limits to avoid crashes. It alerts me when I too slow and also when I’m too fast. Specifically when picking up speed, the Bryton 420 beeps to alert that my speed is near to a fast level. Maps gps are extra. But crashing is not an option to me. It is set mainly to reduce crashing situations.

I am happy but have noticed a few things that could be polished up a bit.

There are going to be 5 or 6 comments regarding some problems so let me start with “ I am very happy with the item. It is doing everything I need it to do.” The sensors (all Bryton) are working /measuring the parameters and sending the signals to the unit. The unit does send the data to the phone. I am getting what I need out of it.
I was looking for something to measure the normal info plus the less usual information of heart rate and separate left/right power. I didn’t need a lot of GPS functionality and wanted to pay less than the better GPS units so this was great for me. I appreciate Bryton putting this in the product line. For what I use, I give the unit appx 4.25 to 4.5 out of 5.

I have only had 3 issues that I care about.
(1) The heart sensor has quit during a ride on 2 occasions in 8 rides. It stays off for a while and comes back on. It could just need a strap tightening (although it feels pretty tight.) This my first heart rate sensor so it could be me. I’ll try a few adjustments and check results.
(2) Again, I have only ridden about 8 times and my phone has lost the device like 4 times(software states it needs me to add at least 1 device) . I am not sure why the phone would keep losing the device. I have other items like a blue tooth speaker that may not get used for a month or two and comes right back on every time. It does not take long to add it back, but it is just annoying.
(3) I don’t see a way to read the odometer in the phone. If my bike computer was broken or stolen, I would like to have the record, and I have wanted to see what my mileage was when looking at the phone and the Bryton 420 was not handy.

There are a couple of things that I don’t personally care about but they should work. Others might.

1. On the phone, most data is accurate. However Lap data is having problems. When reading data on the main LAP line, distance and time are accurate. When clicking on a particular lap,the cadence and heart rate are accurate. I do not have a power sensor yet. but speed average and max speed are off. 1st while I have chosen mph, it is reading km/hr. 2nd while the average speed is about 13.8 mph, it shows as 6.16 km/hr (appx 4 mph). I don’t really do laps so I don’t care but it would be something to correct in a future software update. As there are many complicated functions going on that do work, I am surprised something this simple has slipped by.
2. I could not find a way to use a programmed map and be able to see speed , time, heart rate. Am I missing something. I can understand the possibility of a gps conflict and not being able to get data to both the mapping functions and the data functions at the same time. I plan to change my speed distance to use the wheel sensor instead of gps and see if that changed anything but not expecting it to. Again, I don’t plan to use gps maps so it is not that important to me.
3. I have had at least one occasion when the uphill time and downhill time included the “paused time” Normally this is not included (and should not be.) The occasion I noticed the paused time was almost an hour so it was easily noticed.

Good product

Exactly what I need, thank you. Very professional customer service.

Great Value-Priced Bike GPS

I haven't delved very deeply into all the functions and features on this device, but I am very happy with accuracy and the detailed data it provides. The menu system has a learning curve, but once you get it, it is pretty easy to use.
