BICYCLE LIGHTWEIGHTING

Specialist designers of lightweight bicycles that can achieve more with less.

Reduced Stage Times. Better Power Efficiency. Higher Top Speeds.

Why Bicycle Lightweighting Matters

All bicycles, whether road bikes or TT bikes, electrically powered or regularly powered, are all subject to the same laws of physics- specifically Newton's 2nd law of motion. Simply put, the heavier a bicycle is, the greater the power and energy demands required to move it.

For bicycle designers and manufacturers, shedding excess weight is of particular importance when it comes to seeking out every last competitive advantage, in the constant pursuit of maximising rider performance.

Marginal Gains

Excess weight is a particular problem when it comes to hill climbs, crit events & sprinting. Every kilogram of weight saved equates to a 1.2% power gain, or about 2-3 seconds for every 100m climbed.

Although not a lot, on a typical mountain stage this can easily result in over 25 seconds saved, for a typical racer putting out 400 watts over a 15 km ascent.

Minimised Power Losses

With a reduction in weight comes an increase in a rider's power-to-weight ratio. However, that power can't be used effectively if energy is lost to unwanted deformations in the bicycle's frame and front end.

Advanced carbon fibre composite materials have superior strength and stiffness-to-weight ratios, adding stiffness in the directions and locations needed the most. Using high modulus fibres ensures all energy is properly transferred, minimising losses and making every watt count.

Aerodynamic Advantage

In high speed events like triathlons, TTs and mountain descents, aero is undoubtedly king.

Advanced composite materials can be easily formed into complex structural shapes and geometries, unlocking a bicycle design's full potential. Sleek, low drag aero bikes cut through the air, increasing top speeds without increasing power consumption. For example, a 10% reduction in Cd can result in a 3.5% speed increase.

The Benefits of Bicycle Lightweighting

Lightweighting is the art of creating lightweight parts, structures & vehicles that can achieve more with less.

Improve all-round bicycle design & performance with innovative lightweighting techniques.

as pro engineering ltd. is an advanced-engineering consultancy, specialising in the design, development and prototyping of lightweight bicycle components and complete framesets.

We help our ambitious clients to remain relevant and at the forefront of the cycling industry, by transferring the latest in lightweight motorsport design & manufacturing technologies.

The cycling industry offers a lot of crossover potential from the world of motorsport and race car design. In particular, our experience gained in the design and manufacturing techniques of advanced composite materials offers the greatest opportunity for bicycle manufacturers to push the industry boundaries, and take the performance of their designs to the next level.

**//// Why Choose as pro engineering ltd.?**

as pro engineering ltd. already work with large and small bicycle manufacturers across the U.K, helping them to realise the full potential of carbon fibre composites, as well as high-quality modern engineering design techniques.

Experience

We offer world-class engineering services, with a proven track record of delivering bespoke lightweight design solutions to high-profile clients across the U.K and Europe. Such clients and racing teams include: Mercedes-AMG Petronas F1™, Scuderia Ferrari F1™, Toyota Gazoo Racing LMP1 & Koenigsegg Automotive AB.

A Proven Process

We have the resources, capabilities and expertise necessary to problem solve and develop new, bespoke and innovative bicycle designs.

We offer our clients a full design and prototyping service, and can develop concepts from a blank sheet of paper into finalised technical drawings and physical pre-production prototypes.

Client-First Mindset

We're not interested in the volume production element of a project. As a specialist lightweighting design and prototyping engineering consultancy, we instead support you as our client through designs that use the manufacturing methods best suited to your needs only, not anyone else's. This ensures that your project objectives are continually and successfully achieved.

We supply all our clients with the complete, finalised manufacturing and technical information required for procurement and production. This allows you to globally source and manufacture your own high-quality, lightweight parts, working with suppliers whose costs and production schedules best compliment your own budgets and timelines.
