初心者向き。軽くて良いけど従来品より安っぽくショボい。にわかガチ勢には物足りなかったです（笑）仕方なくローラー用にしてますがとりあえず使えるレベル。一世代前のモデルがオススメ

Vélo de troupe assez simple mais mieux si explications en français

I like having my HR data directly in front of me, and I like the highly visible LCD screen. The GPS is probably adequate for road biking, but for mountain biking, it will chop off 50 feet of every switchback. It lost a whole mile on a 8 mile ride compared to my buddy’s Apple Watch Ultra. The AWU is dead-nuts on the dotted trail line on the map, while this thing wanders all over the place. I'm willing to overlook this, because very few GPS's can handle accurate mountain biking mileage, and a $14 wheel speed sensor from "moofit" solves this problem. Maps still look sketchy, but speed and distance is spot-on after you've taken a few rides and calibrated it. I was also annoyed that it did not pair to my bluetooth chest HR monitor, so I had to buy a new ANT+ one for $30. Now that I'm all set up though, the dedicated hr monitor is far more reliable than a watch. The watch gets the job done, but if you're looking for really consistent results, ride after ride, for a real comparison, you can't beat a speed sensor and dedicated hr monitor. One negative is that you can't make the ride a "mountain bike ride", so everything uploads to Strava as a "ride." Bryton does not allow you to even choose between road, gravel, and mountain, which is a major oversight. The Bryton app is sketchy. I'm a developer, and I could have made that app in my garage in a week by myself. Maybe the Bryton developers should buy a Garmin and use it for a week to see how this is supposed to be done. This inability to choose "mountain biking means that you have to go into Strava and edit every single ride you take be "mountain bike" to differentiate between your mountain and road rides. The user interface on the device itself is fine. One good thing -- and this is EXTREMELY good (it cannot be overstated enough) the screen is highly visible and highly customizable with between 8 and 2 stats. The numbers are large and readable while banging down a trail. Regular LCD screens are the way to go in the sun. When you reduce the number of stats, the numbers grow in size. If you're trying to read a watch while mountain biking, you have to take one hand off the bars, which is less than ideal in the gnar. What made the display even better is when I found the "graphs". So instead of just displaying speed as a number, it shows a histogram bar graph along with current, max, and avg speed. Same with heart rate if you want. That little touch reminds me of the split bar graphs that the Runkeeper app used to show for bike rides back in the day, and it is pretty fantastic.

■梱包GARMINとかに比べるとチープです。安価な分こういうところでコストカットしてるんですかね。気にはしません。■GPSの精度基本的に申し分ないです、粗探す方が難しいです。■充電持ち今の所問題なし。まだ買って70km程しか乗っていないが4時間利用で83%残しでした。■道案内近い距離なら悪くないですが、最短ルート？で計算しているのか細い道や普通なら選ばない道を選んできます。知ってる道なら案内通りの道はまず通らないです。笑、再計算は早く精度は悪くないです。あと通る道しか表示されないですが割とわかりやすいです。いい所として、スマホでマップ作成したらその場でデバイスにDLして再案内してくれるので、信号待ちの時間でも難なくできます。■ログ見やすいし精度も高いです。土日ライダーでは十分です。

Simple to use, app is great and all the metrics are easy to read.Don’t like the difficulty to switch back to turn by turn screen if a climb starts, and the turn by turn function is a little slow, so sometimes miss the turns.Apart from that, it’s fantastic for the money!!
