Advice and recommendations from SkatePro
- Get an adult to help you with the assembly
- Use proper tools (see further down what is needed)
- Expect to use at least 1 hour for the assembly (if you have not tried it before)
- If you choose lightweight parts, then bear in mind, that they are usually more easily broken than heavy parts.
- When you receive the package, check if you have everything and the parts fit together before you start to assemble. (You can only return the new/unassembled parts).
- Always tighten all screws and nuts before biking and maintain the bike as described in the manual. Replace defective components & spare parts.
- Avoid water, sand, moist areas.
