10KG only, easy to carry up and down.

Personally I don't think I will be heading proper route anytime soon. I just wanna cycle a bit on weekends when I'm not swimming. And road bike is over my budget at the moment.

there's plenty of other model that can do navigation, depends on your requirement

1. If you just need to track ur current speed
- no doubt cateye wireless is the best option, cheapest in the market
- or u can get shanreen meter, i think RM299, with speed, cadence and also front light, my gf is using this model since she's not enthusiast cyclist

2. if you need GPS data, cadence, heart rate or sync with strava
- entry level with be bryton 10, with cadence sensor oso around 300, or u can buy just the head unit and buy cadence and heart rate sensor individually
- else if u wan better display will be bryton 410, garmin 130

3. if you need navigation
- garmin 130, bryton 430 (around 600+, with minimal map guidance)
- bryton aero60, garmin 520 (around 1k, with slightly more accurate map guidance)

ehh salah, 450 

last time i also got such mirror.. but not useful la.. too tiny view area and sometimes misaligned then seeing wrong angle..
better turn your head to see and it is faster la in my opinion.. just try it few more times will be familiar already one..

You swaying to right sure la ppl stare 9 you..   lagi mau chase ppl for what..
