# FAQ — Assembly & Setup

---

## Assembly

**Are the bikes assembled when they arrive, or do I need to put them together?**
For safe shipping, the bikes arrive **partially assembled** — typically **85–90 % complete**. You will need to attach the front wheel, handlebars, pedals or footpegs, and the seat post, and perform some basic adjustments (brakes, gears).

All necessary tools and clear, step-by-step assembly instructions are included. Assembly videos are also available — see [Technical Guides](https://help.cemotoride.com/link/336).

If you are not comfortable doing this yourself, CEMOTO recommends taking the bike to a **local bike shop** for professional assembly and tuning. Costs vary by shop.

**How much assembly is required for a D-series dirt bike?**
The bike arrives about **85 % pre-assembled**. You only need to attach the **handlebars, front wheel and footpegs**. Most riders are trail-ready in about **20–30 minutes**.

The D02 Track specifically requires four parts to be installed: **front wheel, handlebars, footpegs and headlight**.

**What about eBikes?**
eBikes ship approximately **90 % assembled**. To ship the bike, the pedals, seat, front wheel and sometimes the handlebar are loosened or removed.

**How long does assembly take?**
- **D-series dirt bikes:** 20–30 minutes
- **eBikes:** 30–45 minutes including basic adjustments

**Should I assemble it myself or use a bike shop?**
If you have questions about your ability to assemble the product, consult a qualified bicycle technician. CEMOTO recommends that **two people work together** to assemble an electric bike.

**Is there an assembly video?**
Yes. CEMOTO publishes step-by-step unboxing and assembly videos:

- Off-Road Electric Dirt Bike D02 — Unboxing & Assembly
- Folding eBike B57A — Unboxing & Assembly

Plus individual how-to videos for motors, disc brakes, pedals and battery side guards. See [Technical Guides](https://help.cemotoride.com/link/336).

## First ride

**What should I do before my first ride?**

1. **Charge the battery fully.** The manual recommends an initial charge of up to **12 hours** for the first cycle.
2. **Complete the pre-ride inspection** — brakes, throttle, tires, battery, frame, fasteners, chain, display, lights.
3. **Re-check all fasteners** after assembly; they settle during the first ride.
4. **Practice in a safe open area first** — at least **10 m × 10 m** — riding forward, turning and stopping.
5. **Start in 1st gear (ECO mode).** Do not ride in high gear until fully familiar with the bike.
6. **Ride with an experienced person first** if you are new to the bike.

See [Pre-Ride Inspection](https://help.cemotoride.com/link/300).

**Why won't the bike move when I turn it on?**
On the D-series, turning the electric door lock on makes the instrument light up and display **0 gear**. In this state the vehicle **does not work** — the throttle is inactive by design.

Press the **"+" key** to switch to a gear above 1, and the throttle will respond.

**Do I need to practice before riding on trails?**
Yes. The owner manual recommends elementary exercises in an accessible area of at least 10 m × 10 m to practice riding forward, turning and stopping. Stay relaxed while practicing, and try to practice navigating tight areas, turning and stopping.

**Riding on ordinary roads is not allowed until you can precisely control the motorcycle through tight areas and simulate various terrain.**

Whenever you upgrade your electric motorcycle, experience the feeling of riding again and practice in the same area as the obstacle zone after the upgrade.
