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.

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:

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.

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.
