Bicycle: How to change the suspension oil without a rebuild

Wed, 01 Apr 2026 07:06:44 -0700

I know this is a website that mainly focuses on repair of electronics but does anyone happen to know how to swap the suspension fluid of the Fox Float X mountain bike without a complete disassembly and a rebuild?

Recently I discovered that the screw that acts as a cap for the suspension oil chamber is loose and leaking, and since I bought the shock secondhand I'm pretty sure the previous owner did not tighten it properly. Right now I need to add more suspension oil but every guide I see online requires complete disassembly of the shock with a lot of tools required. I personally do NOT have the skill or the tools, so I'm wondering whether I can add suspension oil without taking it apart. That screw have to be unscrew-able for a reason...

Any help is appreciated and thanks in advance!

On my Mountain bike the front wheel rim had bent sideways while gapping a huge rock in the middle of the trail i was on, it's only a minor bend but i don't there to be any further damage to that wheel before any repairs are done to the rest of the bike, is there any way of repairing this by myself without using any unnecessary amount of tools and without using any biking tools?

MiJia QiCycle Folding Electric Bike: Can't charge anymore the battery

Tue, 30 Dec 2025 22:04:34 -0700

Hello,

I’ve just bought the Xiaimo QiCycle bike, and I was so happy of my purchase.

I’ve ride it to my work for a few time before winter, and I put it in the garage waiting for better days.

The sun comes finaly earlier, and when i tried to charge the battery, nothing works…

I noticed that once connected to the charger, the green led of the charger did not turn red (charging indicator), while the indicator of the bike tells me that it is completely discharged

This green led stay to green, and do not charge the battery:(

Could you tell me what to do to find out if the problem is with the charger or the battery?

Thanks a lot for your responses !

MiJia QiCycle Folding Electric Bike: My Qicycle suddenly has no power assist

Sat, 27 Dec 2025 16:20:40 -0700

The battery level shows it is full and the LCD display shows up normal. Now it is just an ordinary bike with no power assist. The LCD display still shows the speed and watts of the bike when I am padel the bike. The bike has only 150km. Which component I should replace first or how to narrow down the faulty unit? Bike Control unit, torque sensor or the motor?

MiJia QiCycle Folding Electric Bike: Why my cycle is not charging?

Sun, 14 Dec 2025 22:19:30 -0700

Hi,

I purchased this qi cycle on 2019. So far, it was running fine. I usually charge it when the battery level goes below 40%. Yesterday, I put it in charge as battery level went down to 37%, the charging adapter light was green and then there was a click sound and it remains green.

While checking the solution in this group, I found that suggested solution is to either repeatedly plug and unplug to charging or run the front wheel in reverse mode without turning on the cycle. I did both last night and today morning, i found rest 37% is also gone.

Now if I put the adapter on, the while lights in the cycle keep blinking and the light in adapter stay green even after click sound.

Note: Due to rainy season, I didn't ride on this cycle and charging it after a month.

I couldn't find any service center in bangladesh. Can anyone please help?
