Thankfully it isn’t mine. Just something I saw on FB

I want something for commuting or just to ride on weekends, I hate maintenance so I want something single speed, rim brakes, but also around $150😬, I also don’t want used

Hi!

I have been in contact with someone to buy a second-hand Triban RC520 bike. It is the version with a Shimano 105 groupset and semi-hydraulic disc brakes, and I have an agreement to buy it for 350 euros.

Does this seem like a decent deal? And what are things I should look out for when buying it? I've heard that you should check the chain at the big ring to see whether it is loose or not. The bike does seem like it was used quite a bit (or they may be old SPD pedals)?

Someone talk me out of buy my child a $200 woom WOW balance bike. We say one at the store and my child LOVED it. She can't even walk yet but was having the time of her life. Is it worth it? Just good marketing? Radio Flyer steady start for $50 really doesn't look THAT different? Thoughts, experiences, opinions?

But how can I lift up my bike seat? Nothing near that I’ve pulled either way will move, do I need a tool to lift it? Or is there something I’m missing

Riding in my town. Motorist decided that they wanted to be on the other side of the median. To be clear, I don't think this was meant out of any kind of malice towards cyclists. I think the driver was inattentive. But still, first time I've seen something like this...

Hello everyone, I am currently 16 and only started to lock in on cycling around April this year. I am still abit new to the sport but I feel like I am apart of it now :)
What are sum surprisingly low or high stats I have and where should I work on at getting better at. Thanks!
(I haven’t tested all of my areas)

First of all i dont know if its the right subreddit to ask this kind of question if not sorry then.
This is my bike its core. But i dont know if its 27.5 or 29 cause i brought it 2nd hand.
Its been sitting in my room for like 1/1.5 year or so cause, while biking late night coming from on a kind of a dodgy alley, a small glass went inside the tier and it punctured it.
I thought i am gonna fix it, but later started driving or started just walking.
Now i finally decided to fix it and go back on road with this.
I have very basic knowledge idea about bike, thats why i am asking this. Can i change it by myself at home? Or do i have to take it to a bike shop to do it?
Also what kind tier or tube what would i need? I am low on budget so anything that good works would be ideal choice for me rather spending good money on tier, but i wont use it like that.
Again sorry for such a long text and thanks for taking out time and suggesting.

Waaay out of my element here so I’m very thankful to have found y’all’s community. Hopefully you can see what the issue is in the video; sometimes the tensioner doesn’t want to pull back on the chain, causing slack and then it jumps off. What do I need to do?

I need help Identifying this bike

I got these photos 3rd hand so it’s all I have to work with. Someone I know is considering it as a purchase, (seller’s asking $350), and I’ve no clue what the actual value would be. Trying to help the dude out.

I personally love the thing.

Thank you!
