Purpose¶
Give internal sales, product, and training teams a single deck that explains the technical difference between E-3 PRO and E-3H PRO with a clear architecture comparison, structured spec breakdown, and repeatable talk track.
Audience¶
Internal sales, product, and training teams who need to explain the trade-off between mid-motor and hub-motor configurations.
Narrative Shape¶
- State the training objective and source basis
- Clarify the two drivetrain architectures
- Compare the technical differences row by row
- Reinforce the comparison with diagrams and product imagery
- Turn the differences into positioning guidance
Design Direction¶
Use the OVES dark presentation language and the oves-dark-basic page shell with compact technical comparison layouts, disciplined content frames, and high-contrast training readability.
Output Link¶
- Live deck:
