Just ride, eat, sleep and repeat ☝🏻

...position seems not ok: raise the saddle! :)

If you’re riding on the road, get a Garmin Varia taillight/radar unit. Then put the app on your phone. It will warn you about cars coming up behind you.

Get a good light for front and back reflective clothing have fun

You have good form, keep your elbows bent

Always downshift before you think you should

Have fun! And remember that your ride is your ride, nobody else’s

Looking good with fun 👍 maybe glasses and driving gloves. And maybe seat is little too low. That can cause knee pain.

First think getting into bicycle is, get a proper bike fitting.. anything else can come later.

Follow this guide to adjust your saddle height. If you find yourself riding a lot after a few months, consider to do bikefit procedure. https://m.youtube.com/watch?v=sUNgZ_aRRL8
