I worked in bike shops for years, so I built a free website to help people fix their own bikes

2 Upvotes

Hey everyone!
I’ve worked in the bicycle industry for several years, mainly in bike mechanics, sales and workshop operations.
Recently, I started teaching myself AI tools and website development, and I decided to combine what I’m learning with my experience working on bikes.

That’s how I created Bike You Can — a free website designed to help people learn basic bicycle maintenance and repairs at home.

I’m still developing it, adding guides and improving the website.

I’d really appreciate some feedback from fellow cyclists:

● What bicycle repair guides would you find most useful?
● Is there anything you find confusing when trying to fix your bike?
● What would make a repair website easier to use?
Here’s the website: https://www.bikeyoucan.com
I’m not selling anything. It’s a personal project I’m building while learning new skills.

Thanks for any suggestions!

E-bike Weird scraping noise when my Tern HSD P5i is coasting

• Upvotes

I just got a Tern HSD P5i this last spring, and in the last 4-5 months, I've noticed a scraping noise around the back wheel, and it's been getting louder. When I was trying to troubleshoot it earlier today, I noticed that there was no scraping while I was pedaling, but as soon as I started coasting, it started. I thought it might be the brake pads rubbing on the rotor, but since I don't hear it while pedaling, that can't be it. I have to assume that is has something to do with the Nexus hub, unless you all have other suggestions.

Bike Repair Help w/ freewheel. (Single speed)

Thumbnail

1 Upvotes

Hello everyone,

I just had a question for anyone who has experience servicing single speed freewheels.

Mine makes an annoying "tickity-tack" sound when Im pedaling. The ONLY thing on my 24" Superstock 3 that makes any noise. I was able to disassemble, clean and reassemble. Still makes the sound. It SEEMS like the chainring(?) that spins around the hub is loose but I cant tighten the top cone any more. I can grab the chainring and jiggle it side to side. Probably 1/16" of play.

INSIDE the freewheel there were SIX (6) thin spacers. All the vids Ive seen have less. Im not the first owner of the bike and someone has been into this freewheel before.

My question is: Would removing a few spacers allow the removeable top cone to screw further down, thus removing play? Or am I misunderstanding the spacers function? Are the spacers removeable to account for future wear, maybe? I COULD disassemble my bike again and experiment but for a couple reasons, Im trying not to. If not, Ill just roll around sounding like Debo, I guess. Lol.

Sorry its such a long post, I just try to give detailed info to avoid confusion. Thank you to anyone who took the time to read it.

2022 Giant Propel Advanced Pro Headset (stupid design)

Replacing headset bearings on my 2022 Giant Propel Advanced Pro. In order to replace the bottom bearing I have to remove the hydraulic brake line. Do I have to cut the line or can I get it out of the fork with nut and olive in place?

Bike Repair What is the best order for me to do these things?

3 Upvotes

Hello!

I have a bike that I would like to use again, frame looks good but when it comes to the chain, derailleurs, shifters, and tires could use a lot of love. Heavily rusted, so was thinking of replacing all these components.

To be a bit more specific I would like to replace these following components with brand new ones:

- Chain
- Derailleurs (Front and Back)
- Combo Shifter (Left and Right)
- Shifter Cable
- Tire Inner Tube

My question would be I guess in what order would you preform the changes? And what other things might I need besides a screwdriver, Allen wrench, and a bit of elbow grease?

Thank you so much and God bless!

EDIT: I’m on a bit of a budget so looking to just keep it to the essentials.

Bike Repair A fun “how the hell did that happen” question

6 Upvotes

Hi all,

I volunteer at burning man and repair bikes there. I’ve done that for 11 years now. So when I’m talking about “how did this happen”, imagine an old shitty cruiser bike that’s never been maintained and is rusted and absolutely caked with dust and old shitty fur.

A burner came in with a cruiser bike that had a pedal brake on the rear wheel.

-Somehow- the rear wheel got stuck in such a way that the pedal brake applied itself whether you were going forwards OR backwards, so effectively she couldn’t move more than half a wheel rotation in either direction on the rear wheel.

We didn’t have the space or weight to bring spare wheels this year so we basically dusted it off with an air pressure hose, and applied dry lube over and over and over, flipping the bike from side to side to have gravity penetrate the oil.

After about 30 minutes it finally loosened up and she was able to ride.

I never figured out the mechanics of how it failed. How on earth did a pedal brake suddenly work in both directions, and what is the “real world” fix to this? A new wheel or?

Thanks!

PS go easy on me, I am not a professional bike repair person whatsoever and have learned only from others (and probably have terrible habits that you’d never do if you were trying to get a bike to last more than a week).

Is this hissing noise normal on a RockShox SIDLuxe Ultimate Flight Attendant?

2 Upvotes

I recently bought a brand-new Specialized S-Works Epic 8 with a RockShox SIDLuxe Ultimate Flight Attendant rear shock.
The shock makes a brief hissing/squeaking noise only during the first 5–10% of travel near full extension.
Once compressed beyond that point, I can cycle the suspension repeatedly without any noise, as long as I don’t let it fully extend.
I’ve found several SIDLuxe videos showing similar noises, but opinions are mixed.
Is this normal air-chamber equalization, or could it indicate a damper issue?

I’d especially appreciate feedback from SIDLuxe owners or suspension technicians who have had this checked

Check this video I have just uploaded .YouTube short video

I love this bike, and when it broke it was very sad, but i knew i was not giving it up. So i busted out the welder, and after bending the frame back in shape, i weldet it.

I also added some reinforcement to make it stronger than ever.

I bought a new bike. The seat was too narrow so I bought a bigger one. The seat post fell into the frame. I’ve tried everything. I turned it upside down and shook it. Banged it with a hammer. I put WD-40 in there. Nothing is helping. Any ideas?

Want to replace those busted up covers, but I'd like them to be kind of unique. Any ideas? I've seen someone do leather, but it didn't seem to break in very well. Thinking of just wrapping them when I rewrap the bars.

I bought a new Trek Procaliber 9.6, and while washing the bike after first 150km, I noticed this. Is it just a color transition or a crack in the color? It’s on the rear triangle.

I have a decent trek bike I believe a 2010 model. I’ll get a picture when I’m home. I got it as a gift it came with the property. I have been riding it constantly for about a year. Everything works fine I’m trying to figure out what maintenance to replace first. The tires or chain derail hanger? Wire/housing. Brake pads?

Can this be fixed by a bike steel welder, can it be structurally sound?

Got a broken chain stay.

Really want to keep this bike.

Can this be steel welded buy a bike mechanic with welding skills?

Do we do this to older vintage bikes when this happens?
I'll assume that this welding will make it perfectly structurally sound.

What is the history of these actions?

Bike Repair Is this dent a death sentence for my bike frame? Bergamont Grandurance 6 (2022)

Thumbnail
gallery
2 Upvotes

Hey everyone,

I have a 2022 Bergamont Grandurance 6 that unfortunately has a pretty noticeable dent in the downtube, roughly halfway between the head tube and the bottom bracket.

The bike is otherwise in good condition, but I'm not sure how much this kind of damage affects the strength of an aluminum frame.

I weigh around 65 kg (143 lbs) and mostly ride on paved roads (about 80%), with some light gravel riding (20%).

What do you think? Is this dent a death sentence for the frame, or would you still consider it safe to ride?

I'm especially concerned about whether the frame could develop cracks over time or, in the worst case, suddenly fail.

Has anyone had experience with similar dents in aluminum frames?

Bike Repair Chain coming off the cogs

Thumbnail

2 Upvotes

Please help me not walk an hour to work 🙏

I got a second hand bike and it rode fine when picked up and the chain and gears had lubricant added to them and was cleaned up a little.

When it came to me it was also fine but when I took it for a test ride and changed gears the chain came off and I’m not sure which one it’s supposed to go on and have tried different cogs and it’s ridden okay and then the chain falls off again.

I’m not familiar with any type of bike maintenance or repair and I know this is probably an easy fix but I can’t figure it out. I watched a lot of YouTube tutorials and that still didn’t help.

From what I have read and watched I think potentially the chain derailleur needs tightening (if that’s not how it would be phrased then I apologise, I really don’t have a clue lol). I can find the H or L that would supposedly be on the derailleur to tighten the chain.

Anyone who would be able to help me would be a life saver! I’ve just moved house and got this bike to help me commute to work and the train line by me is cancelled for the next 3 months so I’m relying on this bike.

If it’s a dud from what you can tell I’d also like to know up front as it was given to me for free and would just try and source another one asap.

Thank you for any responses in advance!
