General Electric Bike: ¿Por qué se para cuando enciendo la luz delantera?

Sun, 10 Nov 2024 16:52:35 -0700

Cuando se enciende la luz delantera deja de funcionar y aparece error e10 en pantalla. Hay que apagar la luz para que vuelva a funcionar.

Gracias a ambos por vuestro interés. Es una Jansno x50. Primero he comprobado que el cableado está en buen estado. A continuación abrí el display y detecté que un darlington zt127 tiene emisor y colector en corto, de modo que la bicicleta siempre queda encendida (aunque apagaba el display podía acelerar y funcionaba, lo que me parece que no debería hacer). No sé si eso es lo que provocaba el error e10, pero pondré un nuevo zt127 a ver qué pasa y publicaré resultado.

Me gustaría subir una foto del display abierto donde se ve el transistor en cuestión, pero no veo ningún botón para subir archivos. ¿Cómo se hace?

Bicycle: How do I straighten a bent wheel rim?

Fri, 05 Jun 2020 10:18:30 -0700

One of the rims on my bike is very bent; it stops after 1/2 a revolution because the bent part hits the brake pads.

I've heard that I need a spoke key, and also read that the best way to get a rim straight is to just take it to a pro, since it is somewhat of an art. Is this something I can tackle on my own?

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

Wed, 27 May 2026 20:54:30 -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 !

Boosted Board 1st Generation: Replace new battery in Boosted board 1 gen

Sun, 16 Apr 2023 20:39:59 -0700

Hi,

i have a boosted board first generation and my battery is dead. Can somebody explain how i can replace the batteries and the board will work later on :)

I went to an batterie shop and they told me that the batteries are broke for sure they got new batteries but they said it will not work because of the BMS (battery management system)

So my question is: what batteries should i buy which tools do i need and how can i make my boosted board work again. If i charge it now it only runns for 2-3 minutes and then dead :(

the battery shop already took the batteries out from the board and the would make a new akku for me but i also would try it on my own

i would highly appriciate if somebody can help me to get my board fixed, i am from central europe and the shipping to USA would cost me 200 USD. So i would rather try it on my own before sending it to boosted for 200 usd and then pay additional for the repair work

thank you all for any hints

Simon

Surfboard: Can I use normal Solar Rez to repair my epoxy surfboard?

Sun, 11 Oct 2015 15:35:37 -0700

I have an epoxy/Boardworks Hynson twinzer with a few small nicks. I want to patch it up before I sell it but I don't want to ruin the paint on my board or mess anything up. Can I just use my standard solar rez to repair any dings? Will it adhere?

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

Mon, 27 Apr 2026 16:11:18 -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?

Bicycle: How do I convert my road bike to a fixed gear?

Thu, 19 Jun 2025 13:58:54 -0700

This has been answered on the internet in various other places, but I am new to bike repair and modification. The things I have read are geared towards people who seem to know bike parts well. With the exception of my most recent bike, every bike I have ever owned were fixed gears. I got a used road bike specifically to practice working on it and eventually converting it.

That being said, what is the best way to go about converting it to a fixed gear? Like I said, I know next to nothing about the subject, so please feel free to over explain.

Alpine Skis: Wall mounting

Thu, 15 Jul 2010 13:33:13 -0700

How would one go about mounting a pair of really old wooden skis to the wall in my house?

I would rather not drill holes, but I would consider some sort of adhesive.

Thanks

Frank

I'm going to go with dry wall hangars with screws and metal bands around skis. I do not so much worry about the wall since a drywall repair is relatively simple. I do not want to drill through the skis.

Thanks everyone
