When we bought hours about 9/10 years ago we went to a specific 'optics' outlet, one that just sold binoculars & telescopes for bird/wildlife watching.
We tried loads of different ones without knowing the price ...... we both decided on a couple of pairs that we though gave the best vision. Both sets were almost the most expensive in the shop!!! Close to £1000 each pair!!!! We put them down & tried the others that we initially rejected until we found some within our budget & settle on some for under £200 each (still a very similar price now .....

What I'm trying to say here is that, in my opinion binoculars are one of those things that the more you pay the better they'll be.
We use ours regularly & they have had a lot of use over those years & are still in good order.
You need to think how you're going to use them, if they will remain on the bike & you use them from close by, weight won't matter too much, but if you end up walking a bit with them then a lighter pair might be better & they are usually more expensive.
The ones you posted a link to are 10 X 25. They will work & I'm sure will do the job for you but the 10 X's is as powerful as you want to go with hand held as it's more difficult to hold still because of the magnification. The 25 part is the objective lens (front) size & this allows the light into the binoculars, the bigger it is, the more light, the better the image.
Personally I'd go with nothing less than 32.
Go to a photographers or maybe better a nature reserve that has a shop selling them. That way you can try them & see (no pun intended) for yourself.
