Concepts, Design & Engineering of LB007 Vertical Elliptical Trainer
- A home fitness machine with professional-specs and yet a compact footprint
- Vertical elliptical - a better approach to ellipical biomechanics
Problems with Typical Home Fitness Machines
Compromized design due to use-case constraints
To fit home and satisfy the residential delivery requirements, home fitness machines are often designed downsized with compromized structure, construction, performance and durability:
- Lower metal guage
- Less beams and brace supports
- Reduced movement range
Prematuure damage due to user assembly error
To save on shipping costs, home fitness machines are usually packed in smaller pieces. Users need to do assembly job after receiving the package at their home. Assembly error can lead to
- quick wear and tear
- Bolt thread damage
- structural deformation
These damages are often beyond repair, resulting in the waste of the entire machine.
White-label — lack of accountability
Most home fitness machines are white-label products, especially those listed on Amazon market place. Both manufacturerers and sellers are lack of incentive in building a brand with quality products
- Lack of engineering accountiability
- Lack of consistent testing staandards
- Cost-driving design rather than perfformance
- Arbitrarily claimed specs, such as maxium user weight
- Unscientifical movement geometry. As long as it spins, it ships
- Poor or inaccurate biomechanics
- Seller lack of product knowledge for providing proper customer support
The Initiative
As a major OEM supplier, Lin Bo understood these problems firsthand.
He saw an opportunity to create:
- A compact footprint elliptical
- Minimal user assembly
- Professional-grade structure
- Real engineering accountability
Core Engineering Concept
LB007 uses a two-stage transmission system with a high transmission ratio and a smaller flywheel to achieve smooth resistance without excessive mass.
After extensive testing, the optimal configuration was determined as:
- 1:16 transmission ratio
- 2.5 kg flywheel
- Magnetic resistance system
This design produces smooth, responsive resistance without inertia lag.
After 18 months and over half a dozen prototypes, the final blueprint was approved and test production completed.

Vertical Elliptical Motion
Conventional ellipticals are planar four-bar mechanisms with heavy flywheels, producing mostly horizontal elliptical trajectories.
LB007 is fundamentally different.
Its motion is predominantly vertical, which:
- Reduces required floor space
- Engages muscles more effectively
- Reduces knee joint impact
- Supports both cardio and strength training

Fitness as Lifestyle
Jay introduced a key idea:
fitness equipment should be something people love to use.
That philosophy led to:
- The translucent design
- A straightforward 10-year warranty
- Emotional engagement with engineering quality
10-Year Warranty
Jay believes a straightforward 10-year warranty is essential for lifestyle fitness equipment.
Peace of mind encourages consistent daily use—and consistency is what creates results.
ASTM F2810-Based Testing
LB007 satisfies ASTM-based testing requirements to support a recommended maximum user weight of 250 lb, verified under conditions equivalent to:
- 30 minutes per day
- Average resistance
- 10-year lifespan

Inspired by iMac G3
Jay shared the story of the first translucent iMac with the Jintuo team.
Over time, resistance turned into pride.
We believe in introducing products we love ourselves before offering them to customers.

Navymov Brand
Finding a short, meaningful domain is difficult.
navymov.com was available—and perfect.
- “Navy” suggests depth and confidence
- “Mov” represents motion
Blue became the natural brand color—calm, confident, and engineering-driven.
The logo is intentionally understated.
We let the product speak.
Final Engineering Page Closing Paragraph (as requested)
At Navymov, engineering is not hidden—it is celebrated.
LB007 represents our belief that honest mechanics, transparent design, and thoughtful testing create not only better machines, but better long-term relationships with users.
We do not chase trends. We build things meant to last.
