# Technical Guides — Video Library CEMOTO publishes step-by-step assembly and troubleshooting videos. This page is the **catalog**; each video has its own page in the [Video Tutorials](https://help.cemotoride.com/link/393) section, where the video is embedded inline with a short set of written notes. > **Watch for the pattern.** Several CEMOTO technical guides follow the same principle: **check these before replacing parts.** Most reported faults trace back to a connector, an adjustment or a charge state — not a failed component. Working through the checks saves both time and money. --- ## Where to find the tutorials **All 23 videos have dedicated pages** with the player embedded inline and brief written notes: | Section | Tutorials | | --- | --- | | **Assembly** | [D02 dirt bike](https://help.cemotoride.com/link/341) · [B57A folding eBike](https://help.cemotoride.com/link/339) · [Pedals](https://help.cemotoride.com/link/343) · [Battery side guards](https://help.cemotoride.com/link/340) | | **Setup** | [P-Setting guide](https://help.cemotoride.com/link/348) · [Speed unit](https://help.cemotoride.com/link/345) · [Limit speed](https://help.cemotoride.com/link/347) · [Controller reset](https://help.cemotoride.com/link/346) | | **Error codes** | [E02](https://help.cemotoride.com/link/358) · [E06](https://help.cemotoride.com/link/359) · [E07](https://help.cemotoride.com/link/360) · [E08](https://help.cemotoride.com/link/361) · [E09](https://help.cemotoride.com/link/362) · [E13](https://help.cemotoride.com/link/363) | | **Faults without a code** | [Horn not working](https://help.cemotoride.com/link/364) · [Battery not charging](https://help.cemotoride.com/link/357) · [Won't turn on](https://help.cemotoride.com/link/365) | | **Maintenance** | [Motor installation](https://help.cemotoride.com/link/352) · [Motor removal](https://help.cemotoride.com/link/353) · [Front disc brake](https://help.cemotoride.com/link/351) · [D02 lock set](https://help.cemotoride.com/link/350) | | **Electrical** | [Connecting the wires](https://help.cemotoride.com/link/355) | **→ [Go to the Video Tutorials index](https://help.cemotoride.com/link/393)** --- ## The complete video catalog ### Assembly guides | Video | Applies to | Tutorial page | | --- | --- | --- | | Folding eBike B57A — Unboxing & Assembly | B57A folding eBike | [Assembly guide](https://help.cemotoride.com/link/339) | | Off-Road Electric Dirt Bike D02 — Unboxing & Assembly | D02 Classic, D02 Track | [Assembly guide](https://help.cemotoride.com/link/341) | | How to Install a CEMOTO Motor — Step-by-Step Tutorial | D-series | [Installation guide](https://help.cemotoride.com/link/352) | | How to Remove a CEMOTO Motor — Step-by-Step Tutorial | D-series | [Removal guide](https://help.cemotoride.com/link/353) | | How to Install the Front Disc Brake on a CEMOTO Electric Dirt Bike — Step-by-Step Guide | D-series | [Brake guide](https://help.cemotoride.com/link/351) | | How to Install CEMOTO Pedals | eBikes | [Pedal guide](https://help.cemotoride.com/link/343) | | How to install the left and right battery side guards for the CEMOTO D series | D-series | [Side guard guide](https://help.cemotoride.com/link/340) | | How to change the lock set on the D02 | D02 | [Lock set guide](https://help.cemotoride.com/link/350) | ### Setup and configuration | Video | What it covers | Tutorial page | | --- | --- | --- | | D-Series P-Setting Guide in 20 Seconds | Controller parameter menu | [P-Setting guide](https://help.cemotoride.com/link/348) | | Change Speed Unit from KM/H to MPH | Parameter P02 | [Speed unit guide](https://help.cemotoride.com/link/345) | | How to Limit Speed on Your CEMOTO Electric Dirt Bike — Easy Setup Tutorial | Restricting top speed | [Limit speed guide](https://help.cemotoride.com/link/347) | | How to Reset CEMOTO Controller to Factory Settings — FarDriver Tutorial | FarDriver default restore | [Controller reset guide](https://help.cemotoride.com/link/346) | ### Technical support — error codes | Video | Error code | Tutorial page | | --- | --- | --- | | CEMOTO Battery Not Charging?
